Packaging & ESD

Industry-standard static shielding packaging is used for electronic components.Anti-static, light-transparent materials allow easy identification of ICs and PCB assemblies.
The packaging structure provides electrostatic protection based on Faraday cage principles.This helps protect sensitive components from static discharge during handling and transportation.


All products are packed in ESD-safe anti-static packaging. Outer packaging labels include part number, brand, and quantity for clear identification. Goods are inspected prior to shipment to ensure proper condition and authenticity.

ESD protection is maintained throughout packing, handling, and global transportation. Secure packaging provides reliable sealing and resistance during transit. Additional cushioning materials are applied when required to protect sensitive components.

Frequently Asked Questions

What are the thermal management implications when designing with the SP20150R in high-ambient-temperature industrial environments?
The SP20150R, packaged in a TO-220F non-isolated package, relies on direct heatsink mounting for effective thermal dissipation. In ambient temperatures exceeding 50°C, junction temperature must be carefully calculated using the device’s thermal resistance (RθJA) of approximately 62.5°C/W without a heatsink. Engineers should implement a properly sized heatsink with thermal interface material and ensure adequate airflow to maintain Tj below 150°C under full load, especially in enclosed industrial enclosures where convection is limited.
Can the SP20150R be used as a drop-in replacement for the STMicroelectronics STTH2002CT in a 200V rectification application?
While both the SP20150R and STTH2002CT are 200V, 20A rectifiers in TO-220 packages, the SP20150R has a higher forward voltage drop (VF ≈ 1.1V at 10A) compared to the STTH2002CT (VF ≈ 0.95V), leading to increased conduction losses. Additionally, reverse recovery characteristics differ—substitution may affect EMI performance in high-frequency switching circuits. Thermal and efficiency validation is required before deployment, particularly in power supplies with tight thermal budgets.
What layout considerations are critical when integrating the SP20150R into a high-current DC-DC converter design?
Due to the SP20150R’s high surge current capability and fast switching behavior, PCB layout must minimize parasitic inductance in the anode-cathode loop. Use short, wide traces for the power path, place decoupling capacitors close to the device, and avoid routing sensitive analog signals near the diode leads. The TO-220F package’s exposed metal tab is electrically connected to the cathode; ensure isolation if mounting to a grounded chassis unless intentional grounding is part of the design.
Is the SP20150R suitable for use in automotive 12V battery systems subject to load dump transients?
The SP20150R is not rated for automotive load dump conditions (which can exceed 40V for hundreds of milliseconds). Its maximum repetitive reverse voltage is 200V, but transient voltage suppression must be handled externally. For automotive applications, a TVS diode or clamping circuit is required upstream. Consider AEC-Q101 qualified alternatives if long-term reliability under ISO 7637-2 pulse conditions is needed.
How does the SP20150R compare to the Vishay VS-20ETF06PBF in terms of reverse recovery time and switching losses in a PFC stage?
The SP20150R has a typical reverse recovery time (trr) of 35ns, while the VS-20ETF06PBF is optimized for ultrafast recovery (trr ≈ 25ns) with softer recovery characteristics. In a power factor correction (PFC) circuit operating above 50kHz, the SP20150R may exhibit higher switching losses and EMI due to its less controlled recovery profile. For high-efficiency designs, the Vishay part may offer better performance, though the SP20150R remains viable at lower frequencies or where cost is a primary driver.
What derating guidelines should be applied to the SP20150R when operating continuously at elevated case temperatures?
The SP20150R’s forward current rating must be linearly derated above 25°C case temperature. At 100°C case temperature, the allowable continuous forward current drops to approximately 40% of the 20A maximum. Use the derating curve from the datasheet and apply a safety margin of at least 20% in mission-critical applications. Continuous operation near thermal limits accelerates aging and increases the risk of thermal runaway under fault conditions.
Can the SP20150R be paralleled to increase current handling in a high-power rectifier bank?
Paralleling the SP20150R is not recommended without current-sharing measures. Due to manufacturing variations in forward voltage drop (±5% typical), one device may carry disproportionately higher current, leading to thermal imbalance and premature failure. If paralleling is unavoidable, use individual ballast resistors (0.1–0.5Ω, 5W) in series with each diode or select devices from the same batch with matched VF. Active current-sharing circuits are preferred for high-reliability systems.
What are the long-term reliability concerns when using the SP20150R in outdoor solar inverter applications with wide temperature cycling?
The SP20150R, while robust in industrial settings, may experience solder joint fatigue and lead fatigue under repeated thermal cycling from -40°C to +125°C, common in solar installations. The TO-220F package lacks the enhanced thermal cycling performance of specialized packages like TO-247 or D2PAK with copper base. Ensure proper mounting torque (typically 0.6–0.8 Nm) and consider underfill or conformal coating in high-humidity environments to mitigate moisture-induced corrosion.
How should the SP20150R be configured when used in a center-tapped full-wave rectifier for a 100W AC-DC converter?
In a center-tapped configuration, the SP20150R must withstand peak inverse voltage (PIV) equal to twice the transformer secondary peak voltage. Ensure the transformer’s RMS secondary voltage does not exceed 70V to stay below the 200V PIV rating with margin. Account for voltage spikes from leakage inductance by adding an RC snubber across each diode. The SP20150R’s low Qrr helps reduce switching noise, but layout symmetry is critical to balance current sharing between the two diodes.
Is the SP20150R compatible with lead-free soldering profiles, and what reflow precautions are necessary?
The SP20150R is compatible with lead-free soldering per JEDEC J-STD-020, with a peak reflow temperature of 260°C for 10 seconds maximum. However, the TO-220F package is sensitive to thermal shock; preheating to 150–180°C for 60–120 seconds is recommended to minimize stress. Avoid rapid temperature changes during hand soldering—use a temperature-controlled iron set to 350°C with minimal dwell time to prevent delamination or internal wire bond damage.
