Product details
Overview
SMA5J13CHE3/5A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, designed for high-energy surge protection on power and signal lines. It features a 13 V standoff voltage (VWM), 14.4–15.9 V breakdown range (VBR), 500 W peak pulse power (10/1000 µs), clamping voltage of 21.5 V at 23.3 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMA5J13CHE3/5A datasheet, SMA5J13CHE3/5A pinout, SMA5J13CHE3/5A application, or SMA5J13CHE3/5A equivalent, this device is selected for robust overvoltage protection in DC power rails, automotive sensor interfaces, and industrial control inputs where low clamping ratio, fast response (<1 ns), and 150 °C junction operation are critical.
Technical Context
The SMA5J13CHE3/5A operates as a silicon avalanche diode with glass-passivated junction, delivering bidirectional-capable surge suppression in unidirectional configuration. Its 500 W peak pulse power rating is defined under standardized 10/1000 µs waveform conditions, with thermal resistance RθJA = 80 °C/W and RθJL = 25 °C/W enabling effective heat dissipation on standard PCB pads.
It exhibits 1.0 µA maximum reverse leakage at 13 V, 21.5 V clamping voltage at 23.3 A peak pulse current, and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. The HE3 suffix confirms AEC-Q101 qualification and JESD 201 Class 2 whisker resistance.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ13AHE3/A | Same VWM (13 V), identical DO-214AC package, but rated for 400 W PPPM and 19.9 V VC at 20 A | Lower clamping voltage but reduced surge capacity; suitable where peak current rarely exceeds 20 A | Select when tighter clamping is prioritized over single-event 500 W capability |
| ON Semiconductor 1.5SMC13AH | Same VWM/VBR, DO-214AB (SMB) package (larger footprint), 500 W rating, 21.5 V VC at 23.3 A | Requires PCB layout change due to SMB pad dimensions; higher thermal mass improves sustained surge handling | Choose when board space permits larger package and enhanced thermal cycling endurance is needed |
Compared with SMA5J13CHE3/5A, the Littelfuse SMAJ13AHE3/A offers lower clamping but less surge headroom, while the ON Semi 1.5SMC13AH delivers identical electrical performance in a physically larger package-making SMA5J13CHE3/5A optimal for space-constrained AEC-Q101 designs requiring full 500 W compliance.

FAQ
What is the clamping voltage of the SMA5J13CHE3/5A under maximum surge conditions?
The SMA5J13CHE3/5A clamps to 21.5 V when subjected to its rated peak pulse current of 23.3 A (10/1000 µs waveform). This value is measured per ANSI/IEEE C62.35 and guarantees that downstream circuitry sees no more than 21.5 V during a full 500 W transient event, making SMA5J13CHE3/5A suitable for protecting 24 V-rated components in automotive and industrial settings.
Is the SMA5J13CHE3/5A suitable for automotive applications?
Yes, the SMA5J13CHE3/5A carries the HE3 suffix, confirming full AEC-Q101 qualification, MSL Level 1 reflow compatibility, and JESD 201 Class 2 whisker resistance. Its 150 °C maximum junction temperature, 500 W surge rating, and validated performance across temperature extremes make SMA5J13CHE3/5A appropriate for under-hood ECUs, body control modules, and ADAS sensor power rails.
How does the HE3 suffix differ from the E3 suffix in SMA5J13CHE3/5A?
The HE3 suffix indicates AEC-Q101 qualification, JESD 201 Class 2 whisker resistance, and automotive-grade screening-whereas E3 denotes commercial-grade RoHS compliance only. SMA5J13CHE3/5A is therefore tested to stricter reliability standards, including extended temperature cycling and high-acceleration life testing, distinguishing it from non-HE3 variants like SMA5J13AE3/5A.
What is the reverse leakage current of the SMA5J13CHE3/5A at its standoff voltage?
The SMA5J13CHE3/5A specifies a maximum reverse leakage current of 1.0 µA at its 13 V standoff voltage (VWM) and 25 °C ambient. This ultra-low leakage ensures minimal power loss in always-on automotive modules and preserves signal integrity in high-impedance sensor bias networks, directly supporting design goals for battery longevity and measurement fidelity.
Can the SMA5J13CHE3/5A be used in bi-directional configurations?
No-SMA5J13CHE3/5A is a unidirectional TVS diode, indicated by the "A" (not "CA") suffix. Bi-directional operation requires the CA variant (e.g., SMA5J13CA), which has symmetrical breakdown in both polarities. Using SMA5J13CHE3/5A in reverse-biased AC applications would result in forward conduction and potential failure; always verify polarity alignment in schematic and layout for SMA5J13CHE3/5A.
