Product details
Overview
P4KE220-E3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on power and signal lines. It features 209 V to 231 V breakdown voltage (VBR), 185 V stand-off voltage (VWM), 328 V maximum clamping voltage (VC) at 1.2 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used in automotive sensor protection and industrial power supply input stages.
For engineers reviewing the P4KE220-E3/73 datasheet, P4KE220-E3/73 pinout, P4KE220-E3/73 application, or P4KE220-E3/73 equivalent, key selection criteria include unidirectional polarity, DO-41 mechanical compatibility, 175 °C max junction temperature, AEC-Q101 qualification status, and clamping performance under 10/1000 μs surge conditions.
Technical Context
This device operates as a silicon avalanche diode with glass-passivated junction, delivering fast response (<1 ps) and low incremental surge resistance to limit transient overvoltages before they damage downstream ICs or MOSFETs. Its unidirectional configuration uses cathode-band marking and exhibits 3.5 V forward voltage at 25 A test current.
The P4KE220-E3/73 is rated for 400 W peak pulse power (10/1000 μs), 1.5 W steady-state power dissipation on infinite heatsink, and 40 A non-repetitive forward surge current (8.3 ms half-sine). Thermal resistance is 66 °C/W junction-to-lead and 100 °C/W junction-to-ambient (LLead = 10 mm).
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220A | Surface-mount SMB package (vs. DO-41 through-hole); same VBR range and 400 W rating | Requires PCB rework for SMT assembly; better high-frequency response due to lower parasitic inductance | Select when board space is constrained and automated assembly is preferred over manual through-hole insertion |
| 1.5KE220A | Higher 1500 W peak pulse power rating; larger DO-201 package; 209–231 V VBR identical | Used where higher surge margin is required (e.g., outdoor telecom cabinets), but requires larger footprint and thermal mass | Choose when system-level surge testing exceeds IEC 61000-4-5 Level 4 and additional energy absorption is needed |
Compared with SMBJ220A and 1.5KE220A, the P4KE220-E3/73 offers proven through-hole mechanical robustness, AEC-Q101 qualification out-of-box, and optimal cost-performance balance for mid-tier surge protection in automotive and industrial power rails.

FAQ
What is the polarity configuration of the P4KE220-E3/73?
The P4KE220-E3/73 is a unidirectional TVS diode, with the cathode clearly marked by a color band on the DO-41 package body. This configuration allows it to conduct only during reverse-biased overvoltage events, making it suitable for DC power rail and signal line protection where polarity is fixed. The device does not conduct in forward direction beyond its specified 3.5 V forward voltage at 25 A.
Is the P4KE220-E3/73 qualified for automotive applications?
Yes, the P4KE220-E3/73 is AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias, temperature cycling, and ESD per JESD22-A114. This qualification confirms its suitability for use in automotive subsystems such as body control modules, infotainment power supplies, and sensor interfaces exposed to load dump and jump-start conditions.
What is the maximum clamping voltage of the P4KE220-E3/73 under surge conditions?
The P4KE220-E3/73 has a maximum clamping voltage (VC) of 328 V at 1.2 A peak pulse current (IPPM) using the standard 10/1000 μs waveform. This value represents the upper limit of voltage seen by downstream circuitry during a defined transient event and is critical for ensuring protected ICs remain within their absolute maximum ratings.
How does the P4KE220-E3/73 differ from the bidirectional P4KE220CA variant?
The P4KE220-E3/73 is unidirectional, while P4KE220CA is bidirectional - meaning the latter clamps transients of either polarity and has no cathode marking. The unidirectional P4KE220-E3/73 provides lower leakage current below VWM and is preferred for DC applications with known polarity; the CA version suits AC-coupled or floating signal lines where polarity reversal may occur.
What packaging and compliance information applies to the P4KE220-E3/73?
The P4KE220-E3/73 uses the DO-41 (DO-204AL) package with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. The "E3" suffix indicates RoHS-compliant, commercial-grade construction meeting JESD 201 Class 1A whisker resistance. It is not AEC-Q101 qualified unless specified with "HE3" suffix (e.g., P4KE220AHE3/73).
