Product details
Overview
P4KE13CHE3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for circuit protection against ESD and inductive switching transients. It features a 12.4 V minimum breakdown voltage (VBR), 11.1 V maximum stand-off voltage (VWM), 18.2 V clamping voltage (VC) at 22.0 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - deployed on power rails and I/O lines of automotive sensor modules.
For engineers reviewing the P4KE13CHE3/73 datasheet, P4KE13CHE3/73 pinout, P4KE13CHE3/73 application, or P4KE13CHE3/73 equivalent, key selection criteria include its AEC-Q101 qualification, 175 °C max junction temperature, low 1.0 μA reverse leakage at VWM, and compatibility with lead-free reflow and wave soldering per J-STD-002.
Technical Context
This device operates as a unidirectional clamping TVS diode, leveraging glass-passivated junction technology to deliver fast response (<1 ns) and low incremental surge resistance. Its breakdown threshold is tightly specified (12.4–13.7 V at 1.0 mA test current), ensuring reliable turn-on before downstream IC damage.
The P4KE13CHE3/73 is rated for 400 W peak pulse power under 10/1000 μs waveform and supports 40 A non-repetitive forward surge current (8.3 ms half-sine). Thermal resistance is 66 °C/W (junction-to-lead), enabling effective heat dissipation in compact PCB layouts without heatsinking.
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 |
|---|---|---|---|
| SMBJ13A | DO-214AA package; 13.0 V VBR min; 200 W PPPM; 30 A IPPM | Lower power rating and surface-mount only; unsuitable for through-hole legacy designs | Select when board space is constrained and 200 W clamping suffices; not drop-in for P4KE13CHE3/73 due to package and power mismatch |
| 1.5KE13A | DO-201AD package; identical 12.4–13.7 V VBR; 1500 W PPPM; 100 A IPPM | Higher surge capacity but larger footprint and higher VC (21.2 V); requires more PCB area | Choose for extreme surge environments (e.g., industrial motor drives); verify layout clearance for DO-201AD body size |
Compared with SMBJ13A and 1.5KE13A, the P4KE13CHE3/73 offers optimal balance of AEC-Q101 qualification, 400 W pulse handling, DO-41 through-hole compatibility, and low 18.2 V clamping - making it ideal for cost-sensitive, high-reliability automotive and industrial control designs where leaded assembly remains standard.

FAQ
What is the clamping voltage of the P4KE13CHE3/73 and how is it measured?
The P4KE13CHE3/73 has a maximum clamping voltage (VC) of 18.2 V, measured at 22.0 A peak pulse current using a 10/1000 μs waveform per Fig. 1 in Vishay document 88365. This value represents the actual voltage imposed on the protected circuit during a standardized transient event, ensuring downstream ICs remain within safe operating limits. The P4KE13CHE3/73 achieves this with low incremental surge resistance and fast avalanche response.
Is the P4KE13CHE3/73 suitable for automotive applications?
Yes, the P4KE13CHE3/73 is AEC-Q101 qualified (denoted by HE3 suffix), meaning it has passed rigorous stress tests including temperature cycling, high-temperature reverse bias, and ESD per JESD22 standards. Its 175 °C maximum junction temperature, glass-passivated junction, and 1.0 μA leakage at 11.1 V make the P4KE13CHE3/73 appropriate for under-hood and cabin-mounted automotive electronics such as body control modules and sensor interfaces.
What does the "HE3" suffix mean in P4KE13CHE3/73?
The "HE3" suffix in P4KE13CHE3/73 indicates RoHS-compliant construction with AEC-Q101 qualification and JESD201 Class 2 whisker resistance. It distinguishes this variant from commercial-grade "E3" versions (e.g., P4KE13AE3/73) and confirms compliance with automotive reliability requirements. The P4KE13CHE3/73 is not interchangeable with non-HE3 variants in AEC-Q101–mandated designs without requalification.
How does the P4KE13CHE3/73 compare to bidirectional TVS diodes like P4KE13CA?
The P4KE13CHE3/73 is unidirectional and intended for DC line protection where polarity is fixed (e.g., +12 V rail to ground), offering lower leakage and tighter VBR tolerance than bidirectional types. In contrast, P4KE13CA provides symmetrical clamping for AC or floating signals but exhibits higher leakage and wider VBR spread. The P4KE13CHE3/73 should not be substituted for P4KE13CA without verifying circuit polarity and transient directionality.
What is the thermal resistance and power derating behavior of the P4KE13CHE3/73?
The P4KE13CHE3/73 has a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W and a junction-to-ambient rating of 100 °C/W (with 10 mm lead length). Its 1.5 W steady-state power dissipation derates linearly above 75 °C lead temperature, reaching zero at 175 °C. This behavior is defined in Fig. 5 of Vishay document 88365 and ensures predictable thermal performance in both free-air and PCB-conducted cooling scenarios for the P4KE13CHE3/73.
