Product details
Overview
P6KE11AHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for primary-level overvoltage protection of DC power rails and signal lines. It features 600 W peak pulse power (10/1000 μs), 15.6 V maximum clamping voltage at 38.5 A peak pulse current, and 10.5–11.6 V breakdown voltage at 1 mA test current. Used to protect MOSFETs, ICs, and sensor interfaces against inductive switching transients in automotive and industrial control systems.
For engineers reviewing the P6KE11AHE3/54 datasheet, P6KE11AHE3/54 pinout, P6KE11AHE3/54 application, or P6KE11AHE3/54 equivalent, key selection criteria include clamping voltage margin relative to protected device VDS/VCC, standoff voltage compatibility with operating rail (9.4 V max reverse stand-off), thermal resistance (20 °C/W junction-to-lead), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This TVS operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at 9.4 V), but avalanches rapidly (<1 ns response) when transient voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low leakage (<5 μA at VWM).
Designed for single-pulse and low-duty-cycle surge events, it sustains 100 A non-repetitive forward surge (8.3 ms half-sine) and derates linearly above 25 °C ambient-power dissipation drops to 0 W at 175 °C junction temperature. Thermal resistance values (RθJL = 20 °C/W, RθJA = 75 °C/W) define its PCB heat-sinking requirements for sustained surge handling.
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 |
|---|---|---|---|
| SMBJ11A | DO-214AA package (smaller footprint), same VBR range (10.5–11.6 V), identical 600 W rating | Preferred for space-constrained PCBs; lower thermal mass reduces sustained surge capability | Select SMBJ11A when board area is limited and surge duty cycle remains <0.01 % |
| 1.5KE11A | Same DO-15 package but higher 1.5 kW peak power; VBR 10.5–11.6 V, VC 17.5 V at 85.5 A | Used where higher energy transients (e.g., ISO 16750-2) require greater margin | Choose 1.5KE11A only if system-level testing confirms need for >600 W clamping capacity |
Compared with SMBJ11A and 1.5KE11A, P6KE11AHE3/54 offers optimal balance of AEC-Q101 qualification, proven DO-15 manufacturability, and cost-effective 600 W protection-making it ideal for high-volume automotive and industrial designs where reliability and legacy footprint compatibility are critical.

FAQ
What is the maximum clamping voltage of the P6KE11AHE3/54 under surge conditions?
The P6KE11AHE3/54 has a maximum clamping voltage (VC) of 15.6 V at 38.5 A peak pulse current (10/1000 μs waveform). This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuits during transient events. The clamping voltage remains stable due to the device's low incremental surge resistance and glass-passivated junction structure.
Is the P6KE11AHE3/54 suitable for automotive applications?
Yes, the P6KE11AHE3/54 is AEC-Q101 qualified and specifically designed for automotive use. Its −55 °C to +175 °C junction temperature range, robust 600 W surge capability, and DO-15 package with matte tin plating meet requirements for engine bay and chassis-mounted ECUs. The HE3 suffix explicitly denotes AEC-Q101 qualification per Vishay's ordering nomenclature.
How does the P6KE11AHE3/54 differ from the standard P6KE11A-E3/54?
The P6KE11AHE3/54 differs from P6KE11A-E3/54 solely in qualification level: the "H" prefix indicates AEC-Q101 qualification, while the base P6KE11A-E3/54 is commercial grade only. Both share identical electrical parameters (VBR, VC, PPPM), DO-15 package, and RoHS compliance-but only P6KE11AHE3/54 carries the automotive reliability validation required for Tier 1 automotive supply chains.
What is the standoff voltage rating for the P6KE11AHE3/54?
The P6KE11AHE3/54 has a maximum reverse stand-off voltage (VWM) of 9.4 V, meaning it remains in high-impedance state with leakage <5 μA up to this DC or RMS voltage. This allows safe integration on 9 V nominal rails (e.g., automotive battery backup lines) while providing sufficient margin below its 10.5–11.6 V breakdown threshold to avoid false triggering.
Can the P6KE11AHE3/54 be used in bidirectional configurations?
No, the P6KE11AHE3/54 is a unidirectional TVS diode, identified by its cathode band marking. For bidirectional protection, Vishay specifies CA-suffix variants (e.g., P6KE11CA). Using P6KE11AHE3/54 in reverse-biased AC applications would result in forward conduction and potential failure; always match device polarity to circuit topology and transient directionality.
