Product details
Overview
P4KE7.5A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for circuit-level ESD and surge protection. It features 7.13–7.88 V breakdown voltage (VBR), 6.40 V stand-off voltage (VWM), 11.3 V clamping voltage (VC) at 35.4 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - deployed on power rails and I/O lines of automotive sensor interfaces.
For engineers reviewing the P4KE7.5A-E3/54 datasheet, P4KE7.5A-E3/54 pinout, P4KE7.5A-E3/54 application, or P4KE7.5A-E3/54 equivalent, key selection criteria include unidirectional polarity, DO-41 mechanical compatibility, 175 °C max junction temperature, AEC-Q101 qualification status, and thermal resistance (RθJL = 66 °C/W) for board-level thermal design validation.
Technical Context
This TVS diode operates as a voltage-clamping device that remains non-conductive below VWM = 6.40 V and rapidly transitions to low-impedance conduction above VBR = 7.13–7.88 V. Its glass-passivated junction ensures stable leakage performance (<500 μA at VWM) and fast response time (<1.0 ns), enabling effective suppression of ESD transients per IEC 61000-4-2 and lightning surges per IEC 61000-4-5.
The device supports repetitive surge duty cycles up to 0.01 %, with derated peak pulse power above 25 °C ambient per Fig. 2 and thermal impedance profile optimized for lead-mounted PCB layouts. Its matte tin-plated leads comply with J-STD-002 solderability and JESD 201 Class 1A whisker resistance, confirming suitability for automated assembly in automotive-grade production.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.13 V / 7.88 V at 10 mA test current - defines precise clamping onset threshold for overvoltage detection |
| VWM | 6.40 V - maximum continuous reverse working voltage before leakage exceeds 500 μA |
| VC @ IPPM | 11.3 V at 35.4 A - clamped voltage during 400 W transient, limiting downstream IC stress |
| PPPM | 400 W - peak pulse power handling with 10/1000 μs waveform, validated for industrial surge immunity |
| TJ max | +175 °C - enables operation in under-hood automotive environments without thermal shutdown |
| RθJL | 66 °C/W - junction-to-lead thermal resistance informs heatsinking requirements for sustained surge events |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with axial leads; cathode indicated by color band on body. Matte tin-plated leads meet J-STD-002 solderability and JESD 22-B102 reliability standards.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0A | DO-214AA package, 7.0 V VWM, 10.5 V VC @ 34.4 A, same 400 W rating | Surface-mount footprint; lower profile but higher thermal resistance (RθJA ≈ 40 °C/W vs. 100 °C/W for DO-41) | Select when board space is constrained and reflow assembly is preferred over through-hole. |
| 1N6267A | Same DO-41 package, 7.5 V nominal VBR, but 1.5 kW peak power (10/1000 μs), higher VC = 12.5 V | Higher energy handling; used where single-event surge magnitude exceeds 400 W but clamping margin is relaxed | Choose for legacy designs requiring backward compatibility with MIL-STD-1275E load dump profiles. |
Compared with SMBJ7.0A and 1N6267A, the P4KE7.5A-E3/54 offers optimal balance of axial-leaded mechanical robustness, AEC-Q101 qualification, and precise 6.40 V standoff for 5 V system protection - making it preferred for new automotive and industrial through-hole designs where thermal management via lead conduction is prioritized.

FAQ
What is the breakdown voltage range of the P4KE7.5A-E3/54?
The P4KE7.5A-E3/54 has a guaranteed breakdown voltage (VBR) range of 7.13 V to 7.88 V at 10 mA test current, measured per ANSI/IEEE C62.35. This tight tolerance ensures consistent clamping behavior across production lots and supports reliable overvoltage threshold design in 5 V systems where margin above VWM = 6.40 V is critical.
Is the P4KE7.5A-E3/54 suitable for automotive applications?
Yes, the P4KE7.5A-E3/54 carries the E3 suffix indicating RoHS-compliant commercial grade, and its HE3 variant is explicitly AEC-Q101 qualified. While the E3 version itself is not certified, its construction - glass-passivated junction, DO-41 molding meeting UL 94 V-0, and 175 °C TJ max - aligns with automotive environmental requirements, and it is widely deployed in non-safety-critical ECU sensor protection circuits.
What is the clamping voltage of the P4KE7.5A-E3/54 under surge conditions?
The P4KE7.5A-E3/54 clamps to a maximum of 11.3 V at its rated peak pulse current of 35.4 A (10/1000 μs waveform). This value is measured under standardized transient conditions and defines the upper voltage limit imposed on protected circuitry during surge events - essential for verifying compatibility with 5 V logic I/O absolute maximum ratings.
Does the P4KE7.5A-E3/54 have bidirectional capability?
No, the P4KE7.5A-E3/54 is a unidirectional TVS diode, identified by the "A" suffix. Bidirectional variants use the "CA" suffix (e.g., P4KE7.5CA). The unidirectional configuration provides lower leakage and tighter VBR tolerance, making the P4KE7.5A-E3/54 appropriate for DC-biased lines like power rails and single-ended signal paths where polarity is fixed.
What packaging and reel configuration is supplied for the P4KE7.5A-E3/54?
The P4KE7.5A-E3/54 is supplied in 13-inch diameter paper tape and reel format with a base quantity of 5500 units per reel (ordering code /54). Lead length is standardized for DO-41, and the matte tin-plated terminals support wave and selective soldering per J-STD-002, enabling high-yield assembly in automotive and industrial manufacturing lines.
