Product details
Overview
P4KE75CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on signal or power lines. It features a 71.3 V minimum and 78.8 V maximum breakdown voltage at 1 mA test current, 64.1 V standoff voltage, 103 V maximum clamping voltage at 3.9 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform.
For engineers reviewing the P4KE75CA-E3/54 datasheet, P4KE75CA-E3/54 pinout, P4KE75CA-E3/54 application, or P4KE75CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-41 through-hole compatibility, AEC-Q101 qualification (via HE3 variant), 175 °C max junction temperature, and suitability for automotive sensor line protection against inductive switching surges.
Technical Context
This device operates as a voltage-clamped shunt protector: when reverse (or forward, in bidirectional mode) voltage exceeds VBR, it avalanches to divert surge current away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance.
Designed for single-pulse transient suppression, it supports 10/1000 μs waveform compliance per REA standards, with thermal derating above 25 °C ambient and junction-to-lead thermal resistance of 66 °C/W. It exhibits no polarity marking - consistent with bidirectional construction - and maintains clamping performance across -55 °C to +175 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 71.3 V / 78.8 V at 1 mA - defines precise avalanche initiation threshold for reliable overvoltage detection |
| VWM | 64.1 V - maximum continuous working voltage before leakage exceeds 1 μA; sets safe operating margin below VBR |
| VC @ IPPM | 103 V at 3.9 A - clamping voltage during 400 W surge; determines protected circuit's maximum stress level |
| PPPM | 400 W - peak pulse power handling with 10/1000 μs waveform; defines transient energy absorption capacity |
| IPPM | 3.9 A - peak pulse current corresponding to VC; used to size series impedance for current limiting |
| TJ max | +175 °C - maximum junction temperature; enables operation in under-hood automotive environments |
| Package | DO-41 (DO-204AL) - axial-leaded through-hole package with UL 94 V-0 molded epoxy body |
Pinout & Package
DO-41 package: axial-leaded, non-polarized bidirectional device with no cathode band or marking; leads are matte tin-plated, solderable per J-STD-002 and JESD 22-B102, rated for 275 °C solder dip (10 s max).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (unmarked) | Bidirectional terminal pair | Identical electrical behavior in both directions; connects across protected line and ground or differential pair |
| Lead 1 / Lead 2 | Current conduction path | Leads serve as mechanical attachment and thermal path; RθJL = 66 °C/W enables PCB copper pour heat sinking |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable, repeatable breakdown voltage with low leakage drift over temperature and lifetime |
| 400 W peak pulse power (10/1000 μs) | Supports robust protection against ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 Level 3 surges |
| AEC-Q101 qualified (HE3 variant) | Validated for automotive electronics use including engine control, ADAS sensors, and infotainment interfaces |
| Low clamping ratio (VC/VBR ≈ 1.31) | Minimizes voltage overshoot during clamping, reducing stress on downstream ICs like CAN transceivers or ADCs |
| UL 94 V-0 flammability rating | Molding compound meets safety standard for flame resistance in enclosed industrial and automotive enclosures |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting analog sensor outputs (e.g., pressure, temperature) in engine bay modules from load dump and inductive kickback. IC Role / Device Role / Timing Role: Shunt clamping element placed between signal line and chassis ground to limit transient voltage to safe levels. Use Value: Maintains signal integrity by clamping transients to ≤103 V while surviving repeated 400 W pulses per AEC-Q101 stress profiles. |
Use Scenario: Safeguarding 24 V DC digital input channels in programmable logic controllers against field wiring surges. IC Role / Device Role / Timing Role: Bidirectional voltage clamp on isolated input terminals to suppress common-mode and differential transients. Use Value: Enables reliable operation in harsh factory environments where ESD and lightning-induced surges exceed 1 kV. |
| Telecom Line Interface | Consumer Power Adapter Input |
Use Scenario: Protecting RS-485 transceiver bus lines in telecom base station backhaul equipment. IC Role / Device Role / Timing Role: Differential-mode TVS across A/B lines to absorb fast-rising EFT/burst events without distorting data signals. Use Value: Low capacitance (<100 pF typical) preserves signal rise time; bidirectional symmetry avoids polarity installation errors. |
Use Scenario: Secondary-side overvoltage suppression on 12–24 V DC output rails of wall-mounted AC/DC adapters. IC Role / Device Role / Timing Role: Clamp component absorbing residual transients escaping primary-side MOVs and Y-capacitors.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75CA | Surface-mount SMB package (vs. DO-41 through-hole); same VBR range (71.3–78.8 V), 600 W PPPM | Preferred for high-density PCBs; requires reflow-compatible layout; lacks axial lead mechanical robustness | Select SMBJ75CA when board space is constrained and automated SMT assembly is used. |
| P6KE75CA | Higher PPPM = 600 W; same DO-41 package; VBR min/max = 71.3/78.8 V; higher IPPM = 5.2 A | Better suited for systems requiring higher surge margin (e.g., 12 V battery rail protection in commercial vehicles) | Choose P6KE75CA when legacy DO-41 footprint must be retained but 50 % higher pulse power is needed. |
Compared with P4KE75CA-E3/54, SMBJ75CA offers superior power density and automated assembly compatibility but reduced mechanical ruggedness, while P6KE75CA delivers 50 % higher surge capacity in identical through-hole form factor - enabling drop-in upgrades where thermal design allows.

FAQ
What is the polarity configuration of the P4KE75CA-E3/54?
The P4KE75CA-E3/54 is a bidirectional TVS diode with no polarity marking on the DO-41 package. Its symmetrical construction allows identical clamping behavior in both directions - making it ideal for AC-coupled lines or differential signal pairs where polarity assignment is undefined or variable. This eliminates orientation errors during manual assembly.
Does the P4KE75CA-E3/54 meet automotive qualification standards?
The P4KE75CA-E3/54 itself is RoHS-compliant commercial-grade; however, its HE3-suffix variant (P4KE75CAHE3/54) is explicitly AEC-Q101 qualified. The P4KE75CA-E3/54 shares identical electrical and thermal specifications with the HE3 version - only differing in qualification documentation and whisker testing class - so design-in for automotive use requires specifying the HE3 suffix for formal compliance.
What is the maximum clamping voltage of the P4KE75CA-E3/54 under surge conditions?
The P4KE75CA-E3/54 has a maximum clamping voltage (VC) of 103 V at its rated peak pulse current (IPPM) of 3.9 A, measured with a 10/1000 μs waveform. This value represents the highest voltage that will appear across protected circuitry during a full-rated surge event - critical for verifying downstream ICs remain within absolute maximum ratings.
How does the P4KE75CA-E3/54 compare to unidirectional TVS diodes in circuit protection?
Unlike unidirectional TVS diodes (e.g., P4KE75A), the P4KE75CA-E3/54 provides symmetrical clamping for both positive and negative transients without requiring external polarity alignment. This simplifies design for AC signals, floating grounds, or bidirectional buses like RS-485, eliminating risk of incorrect orientation and enabling single-part inventory for dual-polarity protection needs.
What thermal considerations apply when using the P4KE75CA-E3/54 in high-temperature environments?
The P4KE75CA-E3/54 has a maximum junction temperature of +175 °C and thermal resistance RθJL = 66 °C/W. In high-temperature ambient conditions (>75 °C), power derating per Figure 2 is required; PCB copper pour connected to both leads significantly improves heat dissipation. For sustained operation near TJmax, ensure lead temperature (TL) remains ≤75 °C per Figure 5.
