Product details
Overview
P4KE150-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for circuit-level overvoltage protection. It features a 143 V to 158 V breakdown voltage (VBR) at 1 mA test current, 128 V maximum standoff voltage (VWM), and clamps transients to ≤207 V at 1.9 A peak pulse current (IPPM) under 10/1000 μs waveform - used to safeguard MOSFETs and sensor signal lines in automotive power supplies.
For engineers reviewing the P4KE150-E3/54 datasheet, P4KE150-E3/54 pinout, P4KE150-E3/54 application, or P4KE150-E3/54 equivalent, key selection criteria include its 400 W peak pulse power rating, AEC-Q101 qualification, 175 °C max junction temperature, unidirectional polarity with cathode band marking, and DO-41 mechanical compatibility with legacy through-hole PCB layouts.
Technical Context
This TVS diode operates as a clamping device that remains non-conductive below VWM = 128 V and enters avalanche breakdown above VBR = 143–158 V. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1 ns), enabling suppression of ESD and inductive switching spikes before downstream ICs are damaged.
Thermal performance is defined by RθJL = 66 °C/W (junction-to-lead) and RθJA = 100 °C/W (junction-to-ambient, LLead = 10 mm). The device supports repetitive surge duty cycle ≤0.01 % and withstands solder dip up to 275 °C for 10 s per JESD 22-B106.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 143 V / 158 V at IT = 1 mA - defines reliable turn-on threshold for transient clamping |
| VWM | 128 V - maximum continuous reverse operating voltage without significant leakage |
| VC @ IPPM | ≤207 V at IPPM = 1.9 A (10/1000 μs) - clamping voltage seen by protected circuit during surge |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A | DO-214AA package, 130 V VWM, 144–159 V VBR, same 400 W PPPM | SMT footprint; lower thermal resistance (RθJA ≈ 40 °C/W) but requires reflow-compatible layout | Select for space-constrained designs where board area and automated assembly outweigh through-hole serviceability needs. |
| 1.5KE150A | Same DO-41 package, higher 1500 W PPPM, 143–158 V VBR, 128 V VWM | Higher surge capacity suits infrequent but extreme transients (e.g., utility grid coupling); larger junction capacitance | Choose when system-level testing reveals insufficient margin with 400 W rating, especially in industrial mains-connected equipment. |
Compared with SMBJ130A and 1.5KE150A, P4KE150-E3/54 offers optimal balance of proven DO-41 mechanical robustness, AEC-Q101 readiness (via HE3 variant), and cost-effective 400 W protection for mid-tier automotive and industrial applications - without requiring PCB redesign or premium surge margin.

FAQ
What is the breakdown voltage range of the P4KE150-E3/54?
The P4KE150-E3/54 has a specified breakdown voltage (VBR) range of 143 V to 158 V at a test current of 1 mA, measured per ANSI/IEEE C62.35. This range ensures consistent clamping behavior across production lots and validates its use in 125–150 V transient suppression zones, such as automotive load-dump protection circuits where precise voltage thresholding is required.
Is the P4KE150-E3/54 suitable for automotive applications?
Yes, the P4KE150-E3/54 is suitable for automotive applications when selected in the HE3 variant (P4KE150AHE3/54), which is explicitly AEC-Q101 qualified per the Vishay datasheet. The base P4KE150-E3/54 is RoHS-compliant commercial grade; for automotive deployment, engineers must specify the HE3 suffix to ensure qualification for temperature cycling, humidity bias, and mechanical shock testing required in vehicle subsystems.
What is the maximum clamping voltage of the P4KE150-E3/54 under surge conditions?
The P4KE150-E3/54 clamps to a maximum of 207 V when subjected to its rated peak pulse current of 1.9 A under the standard 10/1000 μs waveform. This clamping voltage is measured at the device terminals and represents the upper voltage limit imposed on the protected circuit during transient events - a critical parameter for ensuring downstream components like 200 V-rated MOSFETs remain within safe operating area.
Does the P4KE150-E3/54 have polarity markings, and how is it installed?
Yes, the P4KE150-E3/54 is a unidirectional TVS diode with a visible cathode band on the DO-41 package body. During installation, the banded end (cathode) connects to the line being protected (e.g., 12 V rail), while the anode connects to ground. Incorrect orientation prevents proper clamping and may result in catastrophic failure under reverse surge conditions.
What is the thermal resistance and maximum junction temperature of the P4KE150-E3/54?
The P4KE150-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W and a maximum junction temperature (TJ) of +175 °C. These values allow the device to sustain repeated 400 W pulses in thermally constrained environments - such as sealed automotive junction boxes - provided lead length and copper pour meet Vishay's recommended layout guidelines for heat dissipation.
