Product details
Overview
1.5KA13AHE3/54 from Vishay General Semiconductor is an automotive-grade unidirectional transient voltage suppressor (TVS) diode designed for inductive load switching protection in harsh environments. It delivers 1500 W peak pulse power (10/1000 µs), clamps at 18.2 V @ 82.4 A, and operates up to +185 °C junction temperature - used to safeguard MOSFETs and sensor signal lines in automotive powertrain control units.
For engineers reviewing the 1.5KA13AHE3/54 datasheet, 1.5KA13AHE3/54 pinout, 1.5KA13AHE3/54 application, or 1.5KA13AHE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, 12.4–13.7 V breakdown range, 11.1 V stand-off voltage, low 0.081 %/°C VBR tempco, and RoHS-compliant HE3 packaging with JESD201 Class 2 whisker resistance.
Technical Context
This TVS diode employs Vishay's patented PAR® construction for stable clamping under repeated surge stress and high-temperature operation. Its unidirectional polarity enables precise reverse-biased overvoltage protection on DC power rails and signal paths, with fast response time and low incremental surge resistance ensuring minimal let-through energy during transients.
The device is rated for 200 A non-repetitive forward surge current (8.3 ms half-sine), supports 6.5 W steady-state power dissipation on infinite heatsink at TL = 75 °C, and maintains reliable performance across –65 °C to +185 °C junction temperature range - meeting automotive reliability requirements per AEC-Q101.

|---|---|
Use Scenario: Protects 12 V supply input of diesel/gasoline ECU against load dump transients (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS clamping device placed between battery rail and upstream fuse, shunting surge energy to ground. Use Value: Clamps to 18.2 V at 82.4 A, preventing overvoltage damage to MCU, CAN transceivers, and power management ICs operating at 12 V nominal. | Use Scenario: Shields isolated gate driver ICs (e.g., Si823x) from inductive flyback spikes generated by IGBTs in HVAC compressors or pump inverters. IC Role / Device Role / Timing Role: Fast-response TVS on gate drive supply rail (VDD) to limit voltage overshoot during switching transitions. Use Value: Sub-1 ns response time and 18.2 V clamping ensure gate oxide integrity is preserved even during 100 A+ dI/dt events. |
| Automotive Sensor Signal Line Protection | Telecom Power Supply Surge Suppression |
Use Scenario: Safeguards analog outputs (e.g., pressure, temperature) of automotive sensors connected to body control modules against ESD and cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance unidirectional TVS placed inline on sensor output trace, referenced to chassis ground. Use Value: 11.1 V stand-off voltage avoids signal distortion during normal 0–5 V output range; 18.2 V clamping prevents ADC input saturation or op-amp latch-up. | Use Scenario: Suppresses lightning-induced surges on -48 V telecom rectifier outputs feeding base station backplane power distribution. IC Role / Device Role / Timing Role: Primary-level TVS on DC input bus before DC-DC converters, absorbing multi-kW transients per ITU-T K.20/K.21. Use Value: 1500 W rating and 185 °C max junction temperature support continuous operation in sealed, high-ambient telecom cabinets. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A | 600 W rating, SMB package (surface-mount), lower IPPM (62.7 A), same VBR range (12.4–13.7 V) | Better suited for PCB space-constrained designs; lacks AEC-Q101 qualification and automotive thermal derating data | Select when board area is limited and automotive qualification is not required |
| 1.5KE13A | Same 1500 W rating and VBR, but TO-204AA (DO-41) package, non-automotive grade, no HE3 whisker compliance | Lower cost alternative for industrial/commercial use; not qualified for automotive under-hood deployment | Select for cost-sensitive non-automotive applications where JESD201 Class 2 and AEC-Q101 are unnecessary |
Compared with SMBJ13A and 1.5KE13A, the 1.5KA13AHE3/54 provides higher thermal robustness (185 °C TJ max), automotive qualification, and whisker-resistant plating - making it the only option qualified for safety-critical engine bay applications requiring long-term reliability.

FAQ
What is the clamping voltage of the 1.5KA13AHE3/54 and how is it measured?
The 1.5KA13AHE3/54 has a maximum clamping voltage (VC) of 18.2 V at 82.4 A peak pulse current, tested with a 10/1000 µs waveform per ANSI/IEEE C62.35. This value represents the upper voltage limit imposed on the protected circuit during a standardized surge event, ensuring downstream components remain within safe operating limits. The 1.5KA13AHE3/54 achieves this clamping performance using Vishay's PAR® construction for stable, repeatable behavior.
Is the 1.5KA13AHE3/54 qualified for automotive applications?
Yes, the 1.5KA13AHE3/54 is AEC-Q101 qualified and designated as automotive grade (base P/NHE3). It undergoes rigorous testing for temperature cycling, humidity bias, mechanical shock, and high-temperature operating life - confirming suitability for under-hood applications such as engine control units and transmission control modules. The 1.5KA13AHE3/54 meets all requirements specified in the Vishay document 88300 Rev. 20-Oct-08.
What does the HE3 suffix mean on the 1.5KA13AHE3/54?
HE3 denotes a RoHS-compliant, high-reliability variant with matte tin-plated leads that pass JESD201 Class 2 whisker testing. This ensures long-term reliability in high-temperature, high-humidity automotive environments where tin whisker growth could cause latent short circuits. The HE3 suffix also confirms compliance with EU RoHS Directive 2002/95/EC and WEEE 2002/96/EC. The 1.5KA13AHE3/54 is supplied in 13" paper tape and reel (package code 54, base quantity 1400).
How does the 1.5KA13AHE3/54 differ from the standard 1.5KA13A?
The 1.5KA13AHE3/54 adds HE3-specific qualifications - RoHS compliance, AEC-Q101 certification, JESD201 Class 2 whisker resistance, and enhanced high-temperature reliability - beyond the base 1.5KA13A. While both share identical electrical specs (VBR, VC, PPPM), only the 1.5KA13AHE3/54 is approved for automotive safety-critical systems. The 1.5KA13AHE3/54 is packaged in 13" paper tape and reel (code 54), whereas standard variants may use bulk or different reels.
What is the maximum operating temperature for the 1.5KA13AHE3/54?
The 1.5KA13AHE3/54 has a maximum junction temperature (TJ) of +185 °C and operates from –65 °C to +185 °C. This extended range supports placement in high-heat zones such as near engines or power converters. Derating curves (Fig. 2 and Fig. 5 in Vishay doc 88300) define allowable pulse power and steady-state dissipation versus ambient and lead temperature - critical for thermal design of the 1.5KA13AHE3/54 in automotive ECUs.
