Product details
Overview
P4KE36CHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for robust overvoltage protection of sensitive electronics. It features a 34.2 V minimum and 37.8 V maximum breakdown voltage (VBR) at 1.0 mA test current, 30.8 V standoff voltage (VWM), 49.9 V clamping voltage (VC) at 8.0 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - deployed on power rails and signal lines in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the P4KE36CHE3/54 datasheet, P4KE36CHE3/54 pinout, P4KE36CHE3/54 application, or P4KE36CHE3/54 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, DO-41 mechanical dimensions, thermal resistance values, and real-world protection use cases - all aligned to Vishay's official Document Number 88365 (Rev. 16-Sep-2021).
Technical Context
This TVS diode operates as a unidirectional clamping device, leveraging a glass-passivated silicon junction to deliver fast response (<1 ns) and low incremental surge resistance. Its 30.8 V working voltage enables reliable operation across 24 V automotive and industrial supply rails while maintaining <1.0 μA reverse leakage at VWM.
The device sustains 40 A non-repetitive forward surge current (8.3 ms half-sine) and exhibits 66 °C/W typical junction-to-lead thermal resistance. With an operating junction temperature range of –55 °C to +175 °C and AEC-Q101 qualification, it supports under-hood and high-temperature control module deployments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 34.2 V / 37.8 V at 1.0 mA - defines precise voltage threshold where clamping initiates under transient stress |
| VWM | 30.8 V - maximum continuous DC or RMS voltage the device blocks without conduction |
| VC @ IPPM | 49.9 V at 8.0 A - clamped voltage seen by protected circuit during 400 W 10/1000 μs surge |
| PPPM | 400 W - peak transient energy absorption capability per single pulse, critical for ISO 7637-2 pulse 1/2a/5a compliance |
| IFSM | 40 A - surge current handling for 8.3 ms half-sine wave, supporting motor driver and relay coil suppression |
| TJ max. | +175 °C - enables placement near heat-generating components in engine control units and power converters |
| RθJL | 66 °C/W - low thermal resistance allows effective heat transfer to PCB copper or lead frame without 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 |
|---|---|---|---|
| SMBJ36A | DO-214AA package; 36 V VBR (min 34.2 V); 600 W PPPM; higher capacitance (~150 pF) | Better suited for board space-constrained designs; higher clamping voltage (58.1 V) reduces margin for 3.3 V logic protection | Select SMBJ36A when footprint reduction and higher surge rating outweigh clamping voltage trade-off |
| 1.5KE36A | DO-201AD package; same VBR range; 1500 W PPPM; larger body and higher thermal mass | Preferred for high-energy industrial surge environments (e.g., factory automation drives); not AEC-Q101 qualified | Choose 1.5KE36A for non-automotive applications requiring >400 W single-pulse capability and higher IPPM |
Compared with SMBJ36A and 1.5KE36A, the P4KE36CHE3/54 offers AEC-Q101 qualification and optimized clamping performance in the compact DO-41 form factor - making it the preferred choice for cost-sensitive, thermally constrained automotive and industrial control modules where 400 W surge immunity suffices.

FAQ
What is the breakdown voltage tolerance of the P4KE36CHE3/54?
The P4KE36CHE3/54 has a specified breakdown voltage range of 34.2 V to 37.8 V at 1.0 mA test current, corresponding to ±5.6% tolerance around the nominal 36 V rating. This tight VBR window ensures consistent clamping behavior across production lots and supports predictable system-level surge margin analysis in designs using the P4KE36CHE3/54.
Is the P4KE36CHE3/54 suitable for automotive applications?
Yes, the P4KE36CHE3/54 carries the HE3 suffix, confirming AEC-Q101 qualification per Vishay Document Number 88365. Its –55 °C to +175 °C operating junction temperature range, glass-passivated junction, and DO-41 mechanical robustness make it approved for under-hood and chassis-mounted automotive modules - including those referenced in the P4KE36CHE3/54 datasheet.
What does the "HE3/54" suffix mean in P4KE36CHE3/54?
In P4KE36CHE3/54, "HE3" denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; "/54" specifies the preferred package code for 13-inch paper tape and reel delivery with 5500 units per reel. This ordering format is defined in Vishay's official documentation for the P4KE36CHE3/54 product line.
How does the clamping voltage of P4KE36CHE3/54 compare to its breakdown voltage?
The P4KE36CHE3/54 clamps at 49.9 V when subjected to its rated 8.0 A peak pulse current (10/1000 μs), yielding a clamping ratio (VC/VBR) of approximately 1.32. This low ratio - confirmed in the P4KE36CHE3/54 electrical characteristics table - ensures minimal let-through voltage during transients, protecting downstream ICs with narrow absolute maximum ratings.
Can the P4KE36CHE3/54 be used in bidirectional configurations?
No - the P4KE36CHE3/54 is a unidirectional TVS diode, as indicated by the "A" suffix (not "CA"). Bidirectional variants such as P4KE36CA exist in the same family but feature symmetrical breakdown in both polarities. Using the P4KE36CHE3/54 in reverse-biased AC applications would result in unintended conduction; always verify polarity marking and datasheet designation before layout placement of the P4KE36CHE3/54.
