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

Can SP1001-02XTG be used on 5 V or 3.3 V signal lines without affecting normal logic levels?
SP1001-02XTG is commonly suited to 3.3 V and many 5 V signal lines, as long as the steady-state line voltage stays below its 5.5 V reverse standoff limit under all tolerance, startup, and fault conditions. For designs where the normal operating voltage can approach that level, check leakage current, rise-time impact, and any overshoot during hot-plug or power sequencing. If the protected node routinely exceeds 5.5 V, a higher-standoff TVS is usually a better fit.
Where should SP1001-02XTG be placed on the PCB for best transient suppression performance?
SP1001-02XTG should be placed as close as possible to the external connector or entry point so the transient is diverted before it travels through the board. Use a short, low-inductance path to the reference plane or return node, and avoid long thin traces between the connector, the SP1001-02XTG, and the protected IC. In practice, PCB inductance often determines the actual clamp seen by the IC more than the diode’s nominal clamp number.
Is SP1001-02XTG a good choice for USB, sensor buses, or other higher-speed data lines?
SP1001-02XTG can work on some lower-speed or moderate-speed single-ended interfaces, but high-speed suitability depends heavily on line capacitance and PCB parasitics, which are not specified here. For USB, fast ADC inputs, or other timing-sensitive paths, verify that the added capacitance and package parasitics do not distort the signal or reduce eye margin. If the interface is differential or very fast, a dedicated low-capacitance protector is often a safer design starting point.
Can SP1001-02XTG protect a power input, battery rail, or hot-plug supply line?
SP1001-02XTG is described as a TVS diode for general-purpose transient suppression, not as power line protection. It is better matched to low-energy signal or control lines than to sustained power transients, reverse battery, load dump, or large inrush events. For a power rail, the protection network usually needs higher surge energy handling, coordination with series impedance, and sometimes a fuse or ideal-diode stage.
How does SP1001-02XTG compare with ESDALC6V1P3 or ESDALC6V1M3 as a replacement?
SP1001-02XTG can be compared with ESDALC6V1P3 and ESDALC6V1M3 only after checking pinout, package compatibility, working voltage, clamp behavior, and capacitance. A part that looks similar on paper can still behave differently in board-level ESD tests because package inductance and layout coupling change the effective clamp. If your design already passes compliance with one part, a substitute should be validated on the same PCB rather than assumed equivalent.
Can SP1001-02XTG replace a different TVS diode in SOT-23 or a larger package?
SP1001-02XTG may replace another TVS only if the footprint, polarity, channel count, and thermal/pulse performance all align with the existing design. Moving from a larger package to SOT-553 can reduce board area, but the smaller package may also change assembly tolerances and surge current distribution on the PCB. When migrating, confirm that the land pattern, orientation mark, and reflow profile all match the manufacturing flow.
Is SP1001-02XTG suitable for lines that can go below ground or carry bipolar signals?
SP1001-02XTG is a unidirectional device, so it is best suited to ground-referenced lines that should not swing significantly negative in normal operation. If the protected node can see bipolar signaling, negative-going analog waveforms, or AC-coupled behavior, a unidirectional clamp can distort the waveform or conduct during valid excursions. In those cases, a bidirectional protector or a different front-end topology is usually easier to integrate.
How should I evaluate SP1001-02XTG for industrial equipment with repeated ESD or surge events?
SP1001-02XTG should be evaluated at the system level with the actual connector, cable, grounding, and enclosure structure, because repeated hits can create heating and cumulative stress even when single-pulse ratings look acceptable. The 2 A pulse figure is tied to a short waveform, so repeated EFT or surge events need derating and board-level validation. For industrial use, it is common to test the complete assembly against IEC-level disturbance profiles rather than relying only on component specifications.
Does SP1001-02XTG create any special assembly, handling, or storage concerns?
SP1001-02XTG is rated MSL 1, so it does not typically require moisture-sensitive dry-pack handling, which simplifies inventory and assembly flow. The SOT-553 package is small, so stencil design, placement accuracy, and optical inspection need to be set up carefully to avoid tombstoning or polarity errors. For rework, the compact footprint often benefits from controlled hot-air profiles and minimal mechanical disturbance to adjacent parts.
