Product details
Overview
P6KE91A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features a 91 V breakdown voltage (VBR min/max = 86.5–95.5 V at IT = 1.0 mA), 125 V maximum clamping voltage (VC) at 4.8 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 μs waveform.
For engineers reviewing the P6KE91A-E3/54 datasheet, P6KE91A-E3/54 pinout, P6KE91A-E3/54 application, or P6KE91A-E3/54 equivalent, key selection criteria include stand-off voltage (77.8 V), low leakage (<1.0 μA at VWM), AEC-Q101 qualification status, thermal resistance (RθJL = 20 °C/W), and compatibility with automated SMT placement via E3-compliant matte tin leads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ) below its 77.8 V stand-off voltage (VWM), then rapidly avalanches into low-impedance conduction when transient voltage exceeds its 86.5–95.5 V breakdown range. Its glass-passivated junction ensures stable VBR tolerance and fast response time (<1.0 ns).
It is rated for 100 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine), dissipates 5.0 W on infinite heatsink at TL = 75 °C, and maintains operation across –55 °C to +175 °C junction temperature range. The E3 suffix confirms RoHS compliance, JESD 201 Class 1A whisker resistance, and commercial-grade qualification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 86.5 V / 95.5 V at 1.0 mA - defines reliable avalanche initiation threshold with ±5% tolerance |
| VWM | 77.8 V - maximum continuous reverse operating voltage before leakage rises above 1.0 μA |
| VC @ IPPM | 125 V at 4.8 A - clamping voltage limiting downstream circuit stress during 10/1000 μs surge |
| PPPM | 600 W - peak transient energy absorption capability under standardized surge waveform |
| IFSM | 100 A - withstands single 8.3 ms inrush without failure, critical for motor drive or relay coil snubbing |
| RθJL | 20 °C/W - enables thermal design using lead-to-case path; supports >2.5 W steady-state dissipation at TL = 75 °C |
| TJ max. | +175 °C - allows use in under-hood automotive or industrial power supply environments |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ90A | DO-214AA package; lower RθJA (50 °C/W vs. 75 °C/W); same VBR (85.5–94.5 V), slightly lower VC (123 V) | Better suited for surface-mount PCBs with limited board space; requires different footprint and reflow profile | Select SMBJ90A when automated SMT assembly and higher power density are prioritized over through-hole serviceability. |
| 1.5KE91A | Same DO-15 package but higher PPPM (1500 W); identical VBR/VC specs; larger physical size (1.25" length) | Used where legacy 1.5 kW surge immunity is mandated (e.g., UL 1449 Type 2 SPDs) | Choose 1.5KE91A only if system-level surge test requirements exceed 600 W, accepting larger footprint and higher cost. |
Compared with SMBJ90A and 1.5KE91A, P6KE91A-E3/54 offers optimal balance of proven reliability, AEC-Q101 qualification, and cost-effective through-hole manufacturability for mid-tier surge protection in automotive and industrial control systems.

FAQ
What is the breakdown voltage tolerance of P6KE91A-E3/54?
The P6KE91A-E3/54 has a specified breakdown voltage range of 86.5 V to 95.5 V at test current IT = 1.0 mA, representing a ±5% tolerance around the nominal 91 V rating. This tolerance is guaranteed per Vishay's datasheet revision 27-Sep-2021 (Document Number: 88369) and applies to all units bearing the E3/54 ordering code. The P6KE91A-E3/54 maintains this specification across its full operating temperature range.
Is P6KE91A-E3/54 suitable for automotive applications?
Yes, P6KE91A-E3/54 is AEC-Q101 qualified per the manufacturer's documentation, confirming its suitability for automotive subsystems such as body control modules, sensor interfaces, and lighting drivers. The E3 suffix denotes RoHS compliance and JESD 201 Class 1A whisker resistance, while its –55 °C to +175 °C operating range supports under-hood and cabin environments. P6KE91A-E3/54 meets these requirements without requiring derating in standard automotive ambient conditions.
What is the maximum clamping voltage of P6KE91A-E3/54 under surge conditions?
The maximum clamping voltage (VC) of P6KE91A-E3/54 is 125 V, measured at peak pulse current IPPM = 4.8 A using the standardized 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events and is guaranteed per the Electrical Characteristics table in Vishay's official datasheet. P6KE91A-E3/54 achieves this clamping performance with sub-nanosecond response time and low dynamic impedance.
Does P6KE91A-E3/54 have bidirectional capability?
No, P6KE91A-E3/54 is a unidirectional TVS diode, indicated by the "A" suffix (as opposed to "CA" for bidirectional variants). Its cathode is marked with a color band, and it conducts only during reverse-bias overvoltage events. Bidirectional operation would require a part number ending in "CA", such as P6KE91CA. The P6KE91A-E3/54 datasheet explicitly states polarity as unidirectional and provides forward voltage (VF) data only for this configuration.
What packaging format is used for P6KE91A-E3/54?
P6KE91A-E3/54 is supplied in 13-inch diameter paper tape and reel packaging, with a base quantity of 4000 units per reel (ordering code suffix "/54"). The device uses DO-15 (DO-204AC) axial package with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. This packaging supports both manual insertion and wave soldering, and the E3 designation confirms RoHS compliance and JESD 201 Class 1A whisker resistance for P6KE91A-E3/54.
