Product details
Overview
1.5KA13HE3/54 from Vishay General Semiconductor is an automotive-grade unidirectional transient voltage suppressor (TVS) diode designed for high-energy surge protection in power and signal lines. It features a 1500 W peak pulse power rating (10/1000 µs), 11.7–14.3 V breakdown voltage range, 19.0 V maximum clamping voltage at 78.9 A, and AEC-Q101 qualification for under-hood automotive electronics.
For engineers reviewing the 1.5KA13HE3/54 datasheet, 1.5KA13HE3/54 pinout, 1.5KA13HE3/54 application, or 1.5KA13HE3/54 equivalent, key selection criteria include clamping performance at rated surge current, junction temperature derating above 25 °C, RoHS-compliant matte tin plating, and JESD201 Class 2 whisker resistance for high-reliability soldering.
Technical Context
This TVS diode uses patented PAR® construction to achieve low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of inductive switching transients and ESD events. Its unidirectional polarity and 10.5 V stand-off voltage make it suitable for DC-biased protection circuits where reverse leakage must remain below 2 µA at TJ = 150 °C.
The device operates across –65 °C to +185 °C junction temperature range and supports 200 A non-repetitive forward surge current (8.3 ms half-sine). Thermal derating follows Fig. 2 in the datasheet, with full power dissipation (6.5 W) only at TL = 75 °C on infinite heatsink.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13AHE3/52 | Lower peak pulse power (600 W), smaller SMB package, 13.3 V clamping at 43.3 A | Better suited for space-constrained PCBs with lower surge energy requirements (e.g., consumer USB ports) | Select when board area is limited and surge threat level is ≤600 W; not AEC-Q101 qualified |
| 1.5KE13A | Same 1500 W rating but TO-204AA (DO-41) package; higher thermal resistance; no HE3 suffix or JESD201 Class 2 whisker test | Acceptable for industrial non-automotive use where extended temperature reliability is less critical | Choose for cost-sensitive non-automotive designs; avoid in AEC-Q101-mandated automotive modules |
Compared with SMBJ13AHE3/52 and 1.5KE13A, the 1.5KA13HE3/54 delivers superior thermal robustness (185 °C TJ max), automotive qualification, and consistent clamping performance under repeated high-current surges-critical for safety-critical vehicle subsystems.

FAQ
What is the clamping voltage of the 1.5KA13HE3/54 at its rated peak pulse current?
The 1.5KA13HE3/54 has a maximum clamping voltage (VC) of 19.0 V at 78.9 A peak pulse current (10/1000 µs waveform). This value is measured per ANSI/IEEE C62.35 standards and ensures protected circuits remain below critical overvoltage thresholds during standardized surge events. The 1.5KA13HE3/54 maintains this clamping performance across its full operating temperature range.
Is the 1.5KA13HE3/54 qualified for automotive applications?
Yes, the 1.5KA13HE3/54 is AEC-Q101 qualified and designated as high-reliability/automotive grade (Base P/N HE3). It undergoes rigorous stress testing-including temperature cycling, high-temperature reverse bias, and mechanical shock-to meet automotive under-hood requirements. The 1.5KA13HE3/54 is explicitly listed in Vishay's AEC-Q101 certified product list per Document Number 88300.
What does the HE3/54 suffix mean in 1.5KA13HE3/54?
The HE3 suffix indicates RoHS compliance, high-reliability construction, and JESD201 Class 2 whisker resistance-critical for lead-free reflow assembly in automotive manufacturing. The /54 denotes the preferred package code: 13" diameter paper tape and reel, with 1400 units per reel. This packaging format ensures automated placement compatibility and moisture-sensitive handling per J-STD-020.
How does the 1.5KA13HE3/54 compare to the 1.5KA13A variant?
The 1.5KA13HE3/54 and 1.5KA13A share identical electrical characteristics (VBR, VC, IPPM) but differ in qualification and plating. The 1.5KA13HE3/54 adds AEC-Q101 certification, JESD201 Class 2 whisker resistance, and matte tin plating per J-STD-002. The 1.5KA13A lacks these automotive-specific qualifications and is intended for industrial use only.
What is the maximum operating junction temperature for the 1.5KA13HE3/54?
The 1.5KA13HE3/54 has a maximum operating junction temperature (TJ) of +185 °C, validated per AEC-Q101 stress testing protocols. This enables reliable operation in under-hood automotive locations where ambient temperatures exceed 125 °C. Derating curves (Fig. 2) specify reduced peak pulse power above 25 °C ambient, ensuring thermal safety margins are maintained throughout the 1.5KA13HE3/54's operational life.
