Product details
Overview
P4KE150HE3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in DO-41 package, designed for clamping inductive switching surges and lightning-induced transients on power rails and signal lines. It features 150 V breakdown voltage (VBR min/max: 143–158 V), 128 V stand-off voltage (VWM), 207 A peak pulse current (IPPM), 207 V clamping voltage (VC) at IPPM, and 400 W peak pulse power (10/1000 μs waveform). It is AEC-Q101 qualified and used in automotive power supply protection.
For engineers reviewing the P4KE150HE3/54 datasheet, P4KE150HE3/54 pinout, P4KE150HE3/54 application, or P4KE150HE3/54 equivalent, key selection criteria include unidirectional polarity, DO-41 mechanical compatibility, 128 V working voltage margin, 207 V clamping performance under 207 A surge, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device operates as a silicon avalanche diode with glass-passivated junction, optimized for fast response (<1 ns) to transient overvoltages. Its unidirectional configuration provides cathode-anode conduction only during reverse-bias surges, with forward voltage drop of 5.0 V at 25 A per specification note (3).
The thermal design relies on low junction-to-lead resistance (RθJL = 66 °C/W) and supports operation up to 175 °C junction temperature. It is rated for 1.5 W steady-state power dissipation on infinite heatsink at TL = 75 °C and withstands 40 A non-repetitive forward surge (8.3 ms half-sine).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 143 V / 158 V - defines minimum and maximum voltage at which avalanche breakdown begins at 1 mA test current; sets clamping threshold range |
| VWM | 128 V - maximum continuous reverse operating voltage; must exceed normal circuit operating voltage to avoid leakage |
| VC @ IPPM | 207 V - clamped voltage during 207 A 10/1000 μs surge; determines protected circuit's maximum transient exposure |
| IPPM | 207 A - peak surge current capability under standard 10/1000 μs waveform; defines transient energy handling capacity |
| PPPM | 400 W - peak pulse power rating; confirms suitability for high-energy transients like ISO 7637-2 Pulse 1/2a/5a |
| TJ max | +175 °C - maximum junction temperature; enables use in under-hood automotive environments without derating |
| AEC-Q101 | Qualified - validated for automotive electronic systems per stress test requirements including HTGB, H3TRB, and temperature cycling |
Pinout & Package
Package: DO-41 (DO-204AL), axial-leaded, molded epoxy body with matte tin-plated leads. Cathode identified by color band on body end.

Use Value: 207 V clamping ensures protected equipment remains below -40 V absolute minimum rating, preventing MOSFET gate oxide failure in hot-swap controllers. |
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 | DO-214AA package, 150 V VBR, 214 A IPPM, 243 V VC, 600 W PPPM | Higher clamping voltage (+36 V), surface-mount format, higher power rating | Select SMBJ150A when PCB space allows SMD layout and higher surge margin is required; not pin-compatible with axial DO-41 footprint |
| 1.5KE150A | DO-201AD package, same VBR/VWM, 224 A IPPM, 220 V VC, 1500 W PPPM | Higher power rating, larger axial package (5.6 mm diameter vs. DO-41's 2.7 mm), no AEC-Q101 qualification | Choose 1.5KE150A for industrial power supplies needing >400 W surge handling; requires board rework due to larger lead spacing and missing automotive qualification |
Compared with P4KE150HE3/54, SMBJ150A offers superior surge power but sacrifices automotive qualification and introduces SMT assembly complexity, while 1.5KE150A delivers higher energy absorption at the cost of larger size and no AEC-Q101 validation-making P4KE150HE3/54 optimal for space-constrained, automotive-grade designs requiring proven qualification and DO-41 compatibility.

FAQ
What is the polarity configuration of P4KE150HE3/54?
P4KE150HE3/54 is a unidirectional transient voltage suppressor diode, meaning it conducts only in reverse bias during overvoltage events. The cathode is marked by a color band on the body, and its forward voltage drop is specified as 5.0 V at 25 A. This polarity makes P4KE150HE3/54 suitable for DC power rail protection where polarity is fixed and reverse conduction must be blocked during normal operation.
Does P4KE150HE3/54 meet automotive qualification standards?
Yes, P4KE150HE3/54 carries the HE3 suffix, indicating full AEC-Q101 qualification per Vishay's documentation. This includes stress testing for high-temperature reverse bias, humidity, temperature cycling, and mechanical shock-validating its use in automotive power distribution modules, body control units, and infotainment systems where component reliability is critical.
What is the clamping voltage of P4KE150HE3/54 under surge conditions?
The clamping voltage (VC) of P4KE150HE3/54 is 207 V at its rated peak pulse current of 207 A (10/1000 μs waveform). This value represents the maximum voltage seen across the device during a standardized surge event and directly determines the protection level afforded to downstream circuitry such as LDOs, microcontrollers, or CAN transceivers connected to the same rail.
How does the DO-41 package of P4KE150HE3/54 impact thermal performance?
The DO-41 package of P4KE150HE3/54 provides a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W, enabling effective heat transfer to PCB copper or external heatsinking. Its axial lead form supports manual or wave soldering, and the 100 °C/W junction-to-ambient rating (with 10 mm lead length) allows reliable operation at full 400 W pulse power when mounted with adequate copper area per Vishay's layout guidelines.
Can P4KE150HE3/54 be used in bidirectional applications?
No, P4KE150HE3/54 is strictly unidirectional. Bidirectional variants in the same family use the "CA" suffix (e.g., P4KE150CA). Using P4KE150HE3/54 in AC or floating applications would result in forward conduction during half-cycles, potentially causing overheating or failure. For bidirectional protection, select the CA-suffixed version or pair two unidirectional devices in series opposition.
