Product details
Overview
P6KE100HE3/54 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 95.0–105 V breakdown voltage (VBR), 85.5 V stand-off voltage (VWM), 137 V maximum clamping voltage at 4.4 A peak pulse current, 600 W peak pulse power rating (10/1000 µs), and AEC-Q101 qualification - deployed in automotive engine control units to safeguard microcontrollers against load-dump transients.
For engineers reviewing the P6KE100HE3/54 datasheet, P6KE100HE3/54 pinout, P6KE100HE3/54 application, or P6KE100HE3/54 equivalent, this page delivers verified electrical parameters, DO-204AC package details, clamping behavior under surge conditions, thermal derating guidance, and validated automotive-grade alternatives aligned with ISO 7637-2 pulse 5a requirements.
Technical Context
This TVS operates as a voltage-clamped shunt protector: when reverse-biased voltage exceeds VBR, it avalanches into low-impedance conduction, diverting transient energy away from downstream ICs. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 µA at 85.5 V).
Designed for unidirectional DC protection, P6KE100HE3/54 exhibits 0.057 %/°C temperature coefficient of VBR, 20 °C/W junction-to-lead thermal resistance, and 175 °C maximum junction temperature - enabling reliable operation in under-hood automotive environments with minimal thermal runaway risk.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 95.0 V / 105 V - defines precise avalanche initiation window for repeatable clamping onset |
| VWM | 85.5 V - maximum continuous reverse operating voltage before leakage rises above 1.0 µA |
| VC @ IPPM | 137 V at 4.4 A - clamping voltage during 10/1000 µs surge; limits stress on protected MOSFET gate driver |
| PPPM | 600 W - peak transient power handling capability per single 10/1000 µs pulse |
| IFSM | 100 A - withstands 8.3 ms half-sine surge without failure, critical for alternator load-dump events |
| TJ max. | 175 °C - supports placement near high-power components in engine control modules |
| RθJL | 20 °C/W - enables effective heat transfer to PCB copper pour or heatsinked leads |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ100A | Lower peak pulse power (400 W), SMA package (surface-mount), 100 V VBR min = 95 V | Not AEC-Q101 qualified; suited for commercial PCB space-constrained designs | Select when board area is limited and automotive qualification is not required |
| 1.5KE100A | Same DO-204AC package, higher PPPM (1500 W), but no AEC-Q101 qualification and wider VBR tolerance (95–116 V) | Lacks automotive reliability validation; used in industrial power supplies with less stringent lifetime demands | Choose for higher surge margin where automotive qualification is unnecessary |
Compared with SMAJ100A and 1.5KE100A, P6KE100HE3/54 uniquely combines AEC-Q101 qualification, 600 W surge rating, and tight 95.0–105 V VBR tolerance in the DO-204AC through-hole package - making it the preferred choice for production automotive electronics requiring traceable reliability and legacy-compatible mounting.

FAQ
What is the clamping voltage of P6KE100HE3/54 at its rated peak pulse current?
The P6KE100HE3/54 has a maximum clamping voltage (VC) of 137 V at 4.4 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during surge events. The clamping performance remains consistent across its qualified operating temperature range of –55 °C to +175 °C.
Is P6KE100HE3/54 suitable for automotive applications?
Yes, P6KE100HE3/54 is AEC-Q101 qualified and specifically designed for automotive use, including engine control units and body electronics exposed to load-dump and jump-start transients. Its HE3 suffix confirms compliance with JESD 201 Class 2 whisker resistance and UL 94 V-0 flammability - meeting OEM requirements for under-hood reliability and safety certification.
What does the 'HE3/54' suffix mean in P6KE100HE3/54?
The 'HE3' suffix indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; '54' denotes the preferred package code for 13-inch paper tape and reel delivery (4000 units per reel). This ordering format ensures traceable sourcing, consistent lead finish, and compatibility with automated through-hole assembly processes.
How does P6KE100HE3/54 differ from P6KE100A-E3/54?
P6KE100HE3/54 is AEC-Q101 qualified and meets JESD 201 Class 2 whisker resistance, while P6KE100A-E3/54 is commercial-grade (JESD 201 Class 1A) without automotive qualification. Both share identical electrical specs and DO-204AC packaging, but only P6KE100HE3/54 is approved for production automotive systems requiring validated long-term reliability under thermal and mechanical stress.
Can P6KE100HE3/54 be used in bi-directional protection circuits?
No, P6KE100HE3/54 is a uni-directional TVS diode intended for DC rail protection with cathode marked by a band. For bi-directional applications such as AC line or data-line protection, Vishay specifies CA-suffix variants like P6KE100CA. Using P6KE100HE3/54 in reverse-biased AC configurations would result in forward conduction and failure.
