Product details
Overview
P4KE150HE3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 128 V standoff voltage (VWM), 143–158 V breakdown range (VBR at 1 mA), 207 A peak pulse current (IPPM), and clamps transients to ≤207 V at rated surge-used in automotive power supply inputs, industrial PLC I/O modules, and telecom line interface circuits.
For engineers reviewing the P4KE150HE3/73 datasheet, P4KE150HE3/73 pinout, P4KE150HE3/73 application, or P4KE150HE3/73 equivalent, key selection criteria include its AEC-Q101 qualification, 400 W 10/1000 μs pulse rating, DO-41 mechanical compatibility, and verified clamping performance under repetitive surge stress in harsh environments.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR, it avalanches rapidly (<1 ns response) to divert surge energy away from downstream components. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (≤1.0 μA at 128 V).
Thermal design is constrained by RθJL = 66 °C/W and RθJA = 100 °C/W; maximum junction temperature is 175 °C. The device supports 40 A non-repetitive forward surge (8.3 ms half-sine) and maintains 1.5 W steady-state power dissipation on infinite heatsink at TL = 75 °C.
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 | DO-214AA package; 150 V VBR min, 219 V VC at 172 A; 600 W PPPM | Higher power rating but larger footprint; better suited for PCB space-constrained designs requiring >400 W margin | Select SMBJ150A if board layout allows SMC/SMB package and higher surge margin is required; not pin-compatible with DO-41 |
| 1.5KE150A | DO-201AD package; same VBR/VC specs; 1500 W PPPM (10/1000 μs); higher IFSM (200 A) | Designed for higher-energy transients; requires larger pad layout and thermal relief due to higher PD (5 W) | Choose 1.5KE150A where legacy 1.5 kW surge standards apply (e.g., MIL-STD-1275); DO-201AD mounting differs from DO-41 |
Compared with SMBJ150A and 1.5KE150A, the P4KE150HE3/73 offers AEC-Q101 qualification in the compact DO-41 form factor-making it optimal for automotive and space-limited industrial designs where 400 W surge immunity suffices and axial lead assembly is preferred.

FAQ
What is the clamping voltage of the P4KE150HE3/73 under maximum rated surge?
The P4KE150HE3/73 clamps to a maximum of 207 V when subjected to its rated 207 A peak pulse current (IPPM) using the standard 10/1000 μs waveform. This value is measured at the device terminals and represents the upper limit of voltage imposed on the protected circuit during surge events.
Is the P4KE150HE3/73 suitable for automotive applications?
Yes, the P4KE150HE3/73 carries the HE3 suffix indicating AEC-Q101 qualification-verified for automotive use across temperature cycling, high-temperature reverse bias, and humidity testing. Its 175 °C max junction temperature and DO-41 mechanical robustness make it appropriate for engine bay and chassis-mounted ECUs.
How does the P4KE150HE3/73 differ from the commercial-grade P4KE150A-E3/73?
The P4KE150HE3/73 is identical in electrical specifications to P4KE150A-E3/73 but adds AEC-Q101 qualification, JESD 201 Class 2 whisker resistance, and enhanced screening for automotive reliability. Both share the same DO-41 package, VBR range (143–158 V), and clamping voltage (207 V), but only the HE3 version is approved for automotive production.
What is the maximum steady-state power dissipation for the P4KE150HE3/73?
The P4KE150HE3/73 has a maximum steady-state power dissipation (PD) of 1.5 W when mounted on an infinite heatsink at lead temperature TL = 75 °C. Derating is required above 25 °C ambient, following the curve in Figure 5 of the Vishay datasheet 88365.
Can the P4KE150HE3/73 be used in bidirectional configurations?
No-the P4KE150HE3/73 is a unidirectional TVS diode. Bidirectional variants require the "CA" suffix (e.g., P4KE150CA). Using the unidirectional P4KE150HE3/73 in AC or symmetrical surge environments would result in forward conduction during negative half-cycles, potentially causing failure.
