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

Is SP24-01WTG-C-HV suitable for a 24V nominal industrial rail that can rise above 24V during tolerance or plug-in events?
SP24-01WTG-C-HV is best used only when the line’s normal operating maximum stays below its 24V reverse standoff. If a “24V” rail can sit at 26V to 28V in steady state, SP24-01WTG-C-HV may start to leak or conduct during normal operation, which can create heating or disturb the rail. For typical 24V industrial inputs with wide tolerance, a higher-VRWM TVS is usually the safer fit.
Can SP24-01WTG-C-HV handle surge events on its own, or does it need upstream protection?
SP24-01WTG-C-HV is a small-signal TVS rated for 3A peak pulse current and 100W peak pulse power under an 8/20µs waveform, so it is not intended to absorb large energy events by itself. It is a good fit for local transient suppression, but for cable-entry surges, inductive kick, or industrial transients, it is usually paired with series impedance, a fuse, or a higher-energy front-end protector.
What PCB layout practices help SP24-01WTG-C-HV clamp transients effectively?
SP24-01WTG-C-HV should be placed as close as possible to the connector or entry point being protected, with very short traces and a low-inductance return path. The 2-FlipChip package works best when the pads are symmetric and the connection to the reference plane is direct. Long trace stubs can add overshoot before the device turns on, which reduces the benefit of the clamp.
Is SP24-01WTG-C-HV a good choice for hot-plug, connector ESD, or cable discharge protection?
SP24-01WTG-C-HV can work well for localized hot-plug or connector ESD protection when the energy level is moderate and the protected node is a 24V-type line. For repeated contact discharge, cable discharge, or harsh IEC 61000-4-2 environments, the surrounding layout matters as much as the part itself. Keeping the device at the connector and minimizing inductance usually improves the real clamp seen by the IC.
Can SP24-01WTG-C-HV replace an SMAJ or SMBJ TVS diode directly?
SP24-01WTG-C-HV is not a footprint-compatible drop-in replacement for DO-214 packages such as SMAJ or SMBJ parts. It uses a compact 2-XFDFN / 2-FlipChip package, so a PCB redesign is needed. Compared with larger SMBJ-class parts, SP24-01WTG-C-HV usually saves board space and can fit closer to the protected IC, but it is not the right substitute when the design needs much higher surge energy handling.
When should I choose SP24-01WTG-C-HV instead of a unidirectional TVS diode?
SP24-01WTG-C-HV is a bidirectional device, so it suits lines that can swing above and below ground or where polarity may reverse during transients. If the node is a fixed-polarity DC rail, a unidirectional TVS often gives more targeted clamping behavior for positive surges. For AC-coupled or polarity-ambiguous interfaces, SP24-01WTG-C-HV is the more natural fit.
Is SP24-01WTG-C-HV appropriate for long-term industrial use at high temperature?
SP24-01WTG-C-HV is specified for -40°C to 125°C junction temperature and is RoHS 3 compliant with MSL 1 handling. In industrial designs, that makes it compatible with many enclosure and board-temperature profiles, provided the TVS is not forced to dissipate continuous overvoltage. Long-term reliability is usually improved by keeping the line within its normal standoff window and avoiding repeated heating from chronic leakage or sustained clamp events.
Can SP24-01WTG-C-HV be used to protect 3.3V or 5V logic lines?
SP24-01WTG-C-HV is generally too high in standoff voltage for 3.3V or 5V logic protection. On low-voltage I/O, a TVS with a much lower reverse standoff and lower clamp threshold is usually needed so the protected IC never sees excessive overshoot. SP24-01WTG-C-HV is better matched to higher-voltage interfaces or 24V-class signals.
Is SP24-01WTG-C-HV suitable as the sole protector for a 24V power entry point?
SP24-01WTG-C-HV is usually not the only component used at a power entry point, especially if the line can see surge, reverse connection, or high-energy switching. Its “power line protection: no” characteristic indicates that it is better viewed as a local transient suppressor rather than a full front-end power protector. In power-entry designs, engineers often add a fuse, reverse-polarity protection, and sometimes a higher-energy TVS in front of sensitive circuitry.
What alternatives should I consider if SP24-01WTG-C-HV does not meet my surge margin or voltage tolerance needs?
If SP24-01WTG-C-HV clamps too late for your system, the first step is usually to move to a lower-VRWM part from the same SPXX family or choose a higher-energy Littelfuse TVS such as an SMBJ- or SMCJ-class device, depending on available board space. The trade-off is straightforward: lower-profile SP24-01WTG-C-HV style parts help with compact layouts and low parasitics, while larger TVS packages usually handle more surge energy and higher cable-entry stress.
