Product details
Overview
P4KE220AHE3/54 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 a 209 V minimum breakdown voltage (VBR), 185 V standoff voltage (VWM), 328 A peak pulse current (IPPM), and 400 W peak pulse power (PPPM) with 10/1000 µs waveform - used to protect MOSFETs and sensor interfaces in automotive ECUs.
For engineers reviewing the P4KE220AHE3/54 datasheet, P4KE220AHE3/54 pinout, P4KE220AHE3/54 application, or P4KE220AHE3/54 equivalent, key selection criteria include clamping voltage (328 V at IPPM), AEC-Q101 qualification, DO-41 mechanical compatibility, and unidirectional polarity with cathode band marking.
Technical Context
This TVS diode operates as a voltage-clamping protection device using an avalanche breakdown mechanism. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, critical for suppressing ESD and inductive switching spikes.
The device is rated for -55 °C to +175 °C operating junction temperature, with thermal resistance of 66 °C/W (junction-to-lead) and 100 °C/W (junction-to-ambient). It meets JESD 22-B106 solderability (275 °C, 10 s) and JESD 201 Class 2 whisker testing (HE3 suffix).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 209 V / 231 V at 1.0 mA test current - defines reliable conduction onset under transient stress |
| VWM | 185 V - maximum continuous reverse working voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 328 V clamping voltage at 328 A peak pulse - limits downstream circuit voltage during surge |
| PPPM | 400 W with 10/1000 µs waveform - quantifies single-pulse energy handling capability |
| IFSM | 40 A non-repetitive forward surge (8.3 ms half-sine) - supports inrush tolerance in DC power paths |
| TJ max. | +175 °C - enables operation in under-hood automotive environments without derating |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling and HTRB |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with matte tin-plated leads; cathode indicated by color band on body end.

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
|
Use Scenario: 24 V battery-supplied control module exposed to load dump (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between VBAT and GND to clamp transients above 185 V while remaining inert during normal operation. Use Value: Limits voltage seen by downstream LDOs and microcontrollers to ≤328 V, preventing latch-up or gate oxide damage. |
Use Scenario: Analog output line (4–20 mA) from pressure sensor routed through noisy factory cabinet with relay coils. IC Role / Device Role / Timing Role: TVS mounted across sensor output and return to suppress inductive kickback induced by nearby contactor switching. Use Value: Clamps transients within 1 ns to protect precision op-amp input stages without affecting 20 kHz signal bandwidth. |
| Telecom Line Card Surge Protection | Consumer Appliance Motor Drive Protection |
|
Use Scenario: DC power feed to remote DSLAM card over long copper runs susceptible to lightning-induced surges. IC Role / Device Role / Timing Role: Primary-level TVS on +48 V input rail, coordinated with upstream GDT and downstream π-filter. Use Value: Absorbs up to 400 W of surge energy per event, enabling compliance with ITU-T K.21 Basic Protection Level. |
Use Scenario: Brushed DC motor driver PCB in washing machine where commutation spikes threaten MCU GPIO and gate drivers. IC Role / Device Role / Timing Role: TVS across motor terminals to shunt back-EMF spikes before they propagate into logic supply domains. Use Value: Withstands 40 A 8.3 ms forward surge, protecting against repeated motor stall events without parameter drift. |
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; 3.5 mm × 3.5 mm footprint; 300 W PPPM; 356 V VC at same IPPM | Surface-mount layout; higher board density but lower surge margin than P4KE220AHE3/54 | Select SMBJ220A when space-constrained PCBs require SMT assembly and 300 W rating suffices. |
| 1.5KE220A | Same DO-41 package; 1500 W PPPM; 355 V VC; higher IPPM (423 A); no AEC-Q101 qualification | Higher-energy industrial surge environments; not validated for automotive temperature cycling or lifetime stress | Choose 1.5KE220A for non-automotive 1500 W surge requirements where AEC-Q101 is unnecessary. |
Compared with SMBJ220A and 1.5KE220A, P4KE220AHE3/54 uniquely balances AEC-Q101 qualification, axial DO-41 serviceability, and 400 W surge capacity - making it optimal for automotive and industrial replacements where reliability traceability and through-hole service access are required.

FAQ
What is the clamping voltage of P4KE220AHE3/54 and how is it measured?
The clamping voltage (VC) of P4KE220AHE3/54 is 328 V, measured at its rated peak pulse current (IPPM) of 328 A using a 10/1000 µs double-exponential waveform per IEC 61000-4-5. This value reflects the maximum voltage imposed on the protected circuit during worst-case surge conditions and is confirmed in the Vishay datasheet Document Number 88365, page 2.
Is P4KE220AHE3/54 suitable for automotive applications?
Yes, P4KE220AHE3/54 is AEC-Q101 qualified (note in datasheet page 3), with operating junction temperature range of -55 °C to +175 °C and validation for temperature cycling, highly accelerated life testing, and surge robustness. Its HE3 suffix confirms compliance with automotive whisker resistance (JESD 201 Class 2) and RoHS requirements.
What does the "HE3/54" suffix mean in P4KE220AHE3/54?
The "HE3" suffix indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; "/54" denotes packaging in 13-inch paper tape and reel with 5500 units per reel. This ordering code aligns with Vishay's standard delivery format for high-volume automotive and industrial procurement.
How does P4KE220AHE3/54 differ from P4KE220A-E3/54?
P4KE220AHE3/54 is AEC-Q101 qualified and meets JESD 201 Class 2 whisker resistance, whereas P4KE220A-E3/54 is commercial grade (JESD 201 Class 1A). Both share identical electrical specs and DO-41 package, but only the HE3 version is approved for automotive under-hood use per Vishay's material categorization documentation.
Can P4KE220AHE3/54 be used in bidirectional configurations?
No - P4KE220AHE3/54 is unidirectional, as indicated by the "A" suffix (not "CA"). Bidirectional variants like P4KE220CA exist but have different breakdown symmetry and no cathode marking. Using P4KE220AHE3/54 in bidirectional circuits would result in forward conduction during negative transients, causing failure.
