Product details
Overview
P4KE75-E3/54 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 71.3 V minimum breakdown voltage (VBR), 64.1 V maximum standoff voltage (VWM), 103 V clamping voltage (VC) at 3.9 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the P4KE75-E3/54 datasheet, P4KE75-E3/54 pinout, P4KE75-E3/54 application, or P4KE75-E3/54 equivalent, key selection criteria include unidirectional polarity, DO-41 leaded package compatibility, 64.1 V working voltage margin, 103 V clamping performance under 3.9 A surge, and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
This device operates as a silicon avalanche diode optimized for transient suppression using controlled reverse-biased breakdown. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low incremental surge resistance, enabling consistent clamping across repetitive 10/1000 μs pulses at 0.01% duty cycle.
The P4KE75-E3/54 exhibits a 0.105 %/°C temperature coefficient of VBR, confirming predictable voltage drift over temperature, and supports 40 A non-repetitive forward surge current (IFSM) - critical for handling inductive switch-off events in DC power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 64.1 V maximum - defines highest continuous DC or RMS voltage the device blocks without conduction |
| VBR (min/max) | 71.3 V / 78.8 V at 1 mA - specifies precise avalanche onset range for reliable transient detection |
| VC @ IPPM | 103 V at 3.9 A - clamping voltage during 10/1000 μs surge, limiting downstream component stress |
| PPPM | 400 W - peak transient energy absorption capability under standardized waveform |
| IFSM | 40 A - single half-sine surge current rating (8.3 ms), supporting inductive load switching protection |
| TJ max | 175 °C - maximum junction temperature enabling operation in under-hood automotive environments |
| Package | DO-41 (DO-204AL) - axial-leaded through-hole package with matte tin-plated leads, UL 94 V-0 compliant |
Pinout & Package
DO-41 (DO-204AL) package: axial-leaded, molded epoxy body with glass-passivated chip; cathode indicated by color band on one end; leads are matte tin-plated and solderable per J-STD-002/JESD 22-B102.

| Cathode | Avalanche clamping terminal | Marked end; sinks transient current when reverse voltage exceeds VWM; clamps to ≤103 V |
Key Features
| Feature | Design Value |
|---|---|

| AEC-Q101 qualified (E3 suffix variant) | Validated for automotive applications including engine control units and body electronics per stress test requirements |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage exposure to protected ICs compared to higher-ratio suppressors |
| UL 94 V-0 molding compound | Meets flammability safety standards for enclosed industrial and automotive enclosures |
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 |
|---|---|---|---|
| SMBJ75A | Surface-mount SMB package; same VWM (64.1 V), slightly lower VC (104 V), 600 W PPPM | Requires PCB redesign for SMT assembly; better suited for space-constrained consumer electronics | Select when board area is limited and automated assembly is preferred over through-hole mounting. |
| 1.5KE75A | Same DO-41 package but higher PPPM (1500 W); VWM = 64.1 V, VC = 118 V at 12.7 A | Higher clamping voltage reduces protection margin for sensitive 3.3 V ICs; suited for heavy industrial surge zones | Choose where higher surge energy (e.g., 4 kV IEC 61000-4-5) must be absorbed, accepting trade-off in clamping level. |
Compared with SMBJ75A and 1.5KE75A, the P4KE75-E3/54 offers optimal balance of through-hole manufacturability, 400 W surge handling, and 103 V clamping - making it ideal for cost-sensitive automotive and industrial designs requiring AEC-Q101 compliance without SMT conversion.

FAQ
What is the polarity configuration of the P4KE75-E3/54?
The P4KE75-E3/54 is a unidirectional TVS diode, with the cathode identified by a color band on the DO-41 package. It conducts only in reverse bias during overvoltage events and blocks forward current up to its specified IFSM. This polarity enables targeted clamping on positive-going transients in DC power rails, and the P4KE75-E3/54 must be oriented with cathode toward the protected circuit's higher potential side.
Does the P4KE75-E3/54 meet automotive qualification standards?
Yes, the P4KE75-E3/54 is AEC-Q101 qualified per Vishay documentation, confirming validation for automotive applications including engine control, body electronics, and infotainment systems. The "E3" suffix denotes RoHS-compliant commercial grade with JESD 201 Class 1A whisker resistance, and full qualification testing covers temperature cycling, humidity, and surge endurance - all verified for the P4KE75-E3/54 part number.
What is the maximum clamping voltage of the P4KE75-E3/54 under surge conditions?
The P4KE75-E3/54 has a maximum clamping voltage (VC) of 103 V at 3.9 A peak pulse current with a 10/1000 μs waveform. This value is measured under standardized test conditions and defines the upper voltage limit imposed on protected circuitry during transient events - critical for ensuring downstream components like 5 V regulators or 3.3 V MCUs remain within safe operating margins. The P4KE75-E3/54 achieves this with low incremental resistance and stable avalanche characteristics.
Can the P4KE75-E3/54 be used in bidirectional protection circuits?
No, the P4KE75-E3/54 is strictly unidirectional and not rated for bidirectional operation. Bidirectional variants in the same family use the "CA" suffix (e.g., P4KE75CA). Using the P4KE75-E3/54 in AC or dual-polarity signal lines would result in forward conduction during negative half-cycles, causing failure or improper clamping. For bidirectional protection, select a CA-suffixed part or pair unidirectional devices anti-parallel - never substitute P4KE75-E3/54 directly.
What is the thermal resistance profile of the P4KE75-E3/54?
The P4KE75-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W and junction-to-ambient resistance (RθJA) of 100 °C/W with 10 mm lead length. These values enable effective heat dissipation during repetitive surge events and support operation up to 175 °C junction temperature. Derating curves in the Vishay datasheet confirm that the P4KE75-E3/54 maintains full 400 W pulse rating only below 25 °C ambient - above that, power must be reduced per Fig. 2, which applies directly to the P4KE75-E3/54.
