Product details
Overview
P4KE220HE3/54 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-41 package, designed for robust overvoltage protection of sensitive electronics. It features a 209 V minimum breakdown voltage (VBR), 185 V maximum standoff voltage (VWM), 328 A peak pulse current (IPPM), and clamps transients to ≤328 V at rated surge - deployed on power rails and signal lines in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the P4KE220HE3/54 datasheet, P4KE220HE3/54 pinout, P4KE220HE3/54 application, or P4KE220HE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, 400 W 10/1000 µs peak pulse power rating, low 1.2 µA reverse leakage at VWM, and DO-41 mechanical compatibility with legacy through-hole layouts.
Technical Context
This device operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its 209–231 V breakdown range (IT = 1.0 mA). Its glass-passivated junction ensures stable VBR tolerance and low dynamic impedance under surge conditions.
Clamping performance is defined by a maximum 328 V clamping voltage (VC) at 328 A IPPM, with thermal resistance RθJL = 66 °C/W enabling reliable power dissipation in constrained PCB environments without heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 209 V / 231 V at 1.0 mA test current - defines precise overvoltage trip threshold for circuit protection |
| VWM | 185 V maximum - ensures no conduction during normal 170 VAC-derived DC rail operation |
| IPPM | 328 A at 10/1000 µs waveform - supports high-energy surge suppression per IEC 61000-4-5 Level 4 |
| VC | ≤328 V at IPPM - limits protected IC voltage stress to safe levels during transient events |
| PPPM | 400 W peak pulse power - enables single-device handling of repetitive 0.01% duty cycle surges |
| TJ max | +175 °C - allows operation in under-hood automotive and high-ambient industrial environments |
| AEC-Q101 | Qualified - certified for automotive-grade reliability including temperature cycling and HTRB |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with axial leads; cathode indicated by color band. Matte tin-plated leads meet J-STD-002 solderability and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference node | Connected to ground or low-voltage return path; forms clamping path during reverse surge |
| Cathode | Protected line input | Connected to line being protected (e.g., 24 V supply rail); conducts avalanche current to anode during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR across temperature and lifetime; eliminates surface degradation under humidity/stress |
| 400 W 10/1000 µs pulse rating | Meets IEC 61000-4-5 surge immunity requirements for industrial and automotive power inputs |
| AEC-Q101 qualification | Validated for automotive applications including engine control, body electronics, and ADAS sensor interfaces |
| Low 1.2 µA IR at VWM | Minimizes standby power loss and avoids false triggering on nominal 185 VDC systems |
| DO-41 mechanical compatibility | Direct drop-in replacement for legacy TVS diodes in existing through-hole designs without layout change |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220A | DO-214AA package; 200 W peak power; lower IPPM (171 A); same VBR range | Suitable for space-constrained SMT designs but requires PCB rework; not AEC-Q101 qualified | Select SMBJ220A only when board real estate is limited and automotive qualification is not required. |
| 1.5KE220A | Same DO-41 package; higher 1500 W peak power; larger 1.5 kW package footprint; VBR 209–231 V | Used where higher surge margin is needed (e.g., outdoor telecom cabinets), but consumes more board area | Choose 1.5KE220A when system-level surge testing exceeds IEC 61000-4-5 Level 4 requirements. |
Compared with SMBJ220A and 1.5KE220A, the P4KE220HE3/54 uniquely balances AEC-Q101 compliance, 400 W surge capability, and DO-41 through-hole compatibility - making it optimal for automotive and industrial replacements where qualification and mechanical fit are mandatory.

FAQ
What is the breakdown voltage tolerance of the P4KE220HE3/54?
The P4KE220HE3/54 has a specified breakdown voltage range of 209 V to 231 V at 1.0 mA test current, corresponding to a ±5% tolerance around the nominal 220 V rating. This tight VBR window ensures consistent clamping behavior across production lots and temperature extremes from –55 °C to +175 °C.
Is the P4KE220HE3/54 suitable for bidirectional transient suppression?
No, the P4KE220HE3/54 is a unidirectional TVS diode - its cathode band indicates polarity, and it conducts only during reverse-biased overvoltage events. For bidirectional protection, Vishay offers the P4KE220CA variant; the "A" suffix in P4KE220HE3/54 explicitly denotes unidirectional configuration.
Does the P4KE220HE3/54 require a heatsink for standard operation?
No, the P4KE220HE3/54 does not require a heatsink under typical transient conditions. Its RθJL of 66 °C/W and 1.5 W steady-state power dissipation rating allow safe operation with standard lead lengths (10 mm) at ambient temperatures up to +75 °C, per Vishay's Fig. 5 derating curve.
How does the HE3 suffix affect the P4KE220HE3/54 specification?
HE3 denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. Unlike the E3 suffix (commercial grade), HE3 confirms automotive-grade reliability testing including HTOL, temperature cycling, and unbiased HAST - critical for under-hood and safety-critical applications.
What is the maximum clamping voltage of the P4KE220HE3/54 at rated surge current?
The P4KE220HE3/54 exhibits a maximum clamping voltage (VC) of 328 V when subjected to its rated 328 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is guaranteed per datasheet Table on page 2 and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
