Product details
Overview
P6KE150AHE3/54 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 150 V breakdown voltage (VBR min/max = 143–158 V), 207 V maximum clamping voltage at 2.9 A peak pulse current, and 600 W peak pulse power dissipation with 10/1000 μs waveform - used for safeguarding MOSFETs, ICs, and sensor signal lines in automotive and industrial power supplies.
For engineers reviewing the P6KE150AHE3/54 datasheet, P6KE150AHE3/54 pinout, P6KE150AHE3/54 application, or P6KE150AHE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, 128 V stand-off voltage (VWM), ≤1.0 μA reverse leakage at VWM, 175 °C max junction temperature, and DO-15 mechanical compatibility with legacy through-hole PCB layouts.
Technical Context
This device operates as a voltage-clamping protection element placed in parallel with the protected circuit node. Its glass-passivated junction enables fast response time (<1 ns) and low incremental surge resistance, ensuring effective suppression of transient energy before downstream components experience overvoltage stress.
The unidirectional configuration provides forward conduction capability up to 100 A IFSM (8.3 ms half-sine), while maintaining 3.5 V max forward voltage at 50 A. Thermal resistance is specified at RθJL = 20 °C/W and RθJA = 75 °C/W, supporting reliable operation under repetitive surge conditions when mounted on standard PCB copper land patterns.
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 |
|---|---|---|---|
| SMBJ150A | Surface-mount SMB package (vs. through-hole DO-15); same VBR range and PPPM, but lower IFSM (100 A → 71.4 A) | Requires PCB redesign for SMT placement; better suited for high-density layouts with automated assembly | Select SMBJ150A only if board space constraints prohibit axial-leaded components and thermal management supports lower surge margin. |
| 1.5KE150A | Same DO-15 package and VBR, but higher PPPM (1500 W vs. 600 W); larger die size increases capacitance and thermal mass | Overqualified for most 12–48 V systems; may require derating in confined thermal environments due to higher power density | Choose 1.5KE150A only when system-level testing confirms need for >600 W surge handling and layout accommodates higher thermal inertia. |
Compared with SMBJ150A and 1.5KE150A, P6KE150AHE3/54 delivers optimal balance of AEC-Q101 qualification, proven DO-15 reliability, and 600 W surge capability - making it the preferred choice for cost-sensitive, thermally constrained, and automotive-qualified through-hole designs.

FAQ
What is the clamping voltage of P6KE150AHE3/54 at its rated peak pulse current?
The P6KE150AHE3/54 has a maximum clamping voltage (VC) of 207 V at its rated peak pulse current (IPPM) of 2.9 A, measured using the standardized 10/1000 μs waveform. This value represents the highest voltage the protected circuit will experience during a full-rated transient event, and it is guaranteed across the operating temperature range per Vishay Document 88369.
Is P6KE150AHE3/54 suitable for automotive applications?
Yes, P6KE150AHE3/54 is AEC-Q101 qualified and explicitly rated for automotive use, with a maximum junction temperature of +175 °C and validation across temperature cycling, high-temperature reverse bias, and ESD tests. Its HE3 suffix denotes compliance with JESD 201 Class 2 whisker resistance and automotive material categorization per Vishay doc# 99912.
How does the DO-15 package of P6KE150AHE3/54 affect thermal performance?
The DO-15 package of P6KE150AHE3/54 provides a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient (RθJA) of 75 °C/W. Effective heat dissipation requires adequate copper land area on the PCB and proper lead length control (0.375" recommended); thermal derating above 25 °C ambient follows the curve in Figure 2 of Document 88369.
What is the reverse leakage current specification for P6KE150AHE3/54 at its stand-off voltage?
At its stand-off voltage (VWM) of 128 V, the P6KE150AHE3/54 exhibits a maximum reverse leakage current (ID) of 1.0 μA at 25 °C, as specified in the Electrical Characteristics table of Vishay Document 88369. This low leakage ensures minimal power loss and signal integrity impact in always-on protection circuits.
Does P6KE150AHE3/54 have bidirectional capability?
No, P6KE150AHE3/54 is a unidirectional TVS diode - its cathode is marked with a band and it conducts only in reverse breakdown. For bidirectional protection, Vishay offers the P6KE150CA variant; the "A" suffix in P6KE150AHE3/54 explicitly denotes unidirectional polarity per the ordering nomenclature in Document 88369.
