Product details
Overview
P4KE7.5AHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for circuit protection against ESD and inductive switching transients. It features 7.13 V to 7.88 V breakdown voltage (VBR) at 10 mA, 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 - used in automotive sensor signal lines and industrial I/O interfaces.
For engineers reviewing the P4KE7.5AHE3/54 datasheet, P4KE7.5AHE3/54 pinout, P4KE7.5AHE3/54 application, or P4KE7.5AHE3/54 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, DO-41 mechanical compatibility, thermal resistance (RθJL = 66 °C/W), and low leakage (<500 μA at VWM).
Technical Context
This TVS diode operates as a voltage-clamping overvoltage protection device, triggered when reverse voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5%) and fast response time (<1.0 ns), enabling suppression of transient spikes before downstream ICs are damaged.
The device supports repetitive surge events at 0.01% duty cycle and is rated for operation from –55 °C to +175 °C junction temperature. Its 1.5 W steady-state power dissipation and 40 A non-repetitive forward surge capability (8.3 ms half-sine) make it suitable for high-reliability board-level protection without heatsinking.

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 @ 34.3 A; 600 W PPPM rating | Higher power density but surface-mount only; requires reflow-compatible layout | Select SMBJ7.0A when board space is constrained and SMT assembly is available; not drop-in compatible with P4KE7.5AHE3/54's through-hole DO-41 footprint. |
| 1.5KE7.5A | DO-201AD package; same VBR range (7.13–7.88 V); 1.5 kW PPPM; higher IPPM (123 A) | Larger package size (5.6 mm diameter vs. 2.7 mm); higher thermal mass; suited for higher-energy transients | Choose 1.5KE7.5A where system-level surge testing exceeds 400 W requirements; requires PCB pad redesign due to larger DO-201AD outline. |
Compared with SMBJ7.0A and 1.5KE7.5A, the P4KE7.5AHE3/54 offers optimal balance of AEC-Q101 qualification, axial-leaded DO-41 compatibility for manual repair and high-vibration mounting, and verified performance in 400 W transient scenarios - making it preferred for cost-sensitive automotive and industrial through-hole designs.

FAQ
What is the polarity configuration of the P4KE7.5AHE3/54?
The P4KE7.5AHE3/54 is a unidirectional TVS diode, with the cathode identified by a color band on the DO-41 package body. It conducts in forward bias like a standard diode and clamps in reverse bias above its breakdown voltage. This configuration is required for DC line protection where polarity is fixed, unlike bidirectional variants (e.g., P4KE7.5CA) used in AC or floating signal paths. The P4KE7.5AHE3/54 must be oriented correctly on PCB to avoid unintended conduction.
Is the P4KE7.5AHE3/54 qualified for automotive use?
Yes, the P4KE7.5AHE3/54 carries the HE3 suffix, indicating full AEC-Q101 qualification per Vishay documentation. It has undergone stress testing including temperature cycling, high-temperature reverse bias (HTRB), and ESD per ANSI/ESDA/JEDEC JS-001. This makes the P4KE7.5AHE3/54 suitable for under-hood and cabin applications such as engine control sensors, infotainment interfaces, and ADAS camera modules where automotive-grade reliability is mandatory.
What does the "/54" in P4KE7.5AHE3/54 signify?
The "/54" in P4KE7.5AHE3/54 denotes the preferred package code per Vishay's ordering nomenclature, specifying 13-inch paper tape and reel packaging with a base quantity of 5500 units. It does not affect electrical or thermal specifications. This format aligns with automated SMT placement equipment feed requirements and distinguishes bulk packaging variants - for example, P4KE7.5AHE3/36 uses 7-inch reels. The P4KE7.5AHE3/54 remains electrically identical to other P4KE7.5AHE3 variants.
How does the clamping voltage of P4KE7.5AHE3/54 compare to its breakdown voltage?
The P4KE7.5AHE3/54 has a breakdown voltage (VBR) range of 7.13 V to 7.88 V at 10 mA test current, while its maximum clamping voltage (VC) is 11.3 V at 35.4 A peak pulse current. This 3.4–4.2 V difference represents the dynamic voltage rise under surge conditions - critical for ensuring protected ICs (e.g., 5 V microcontrollers) remain below absolute maximum ratings. The P4KE7.5AHE3/54 maintains this clamping performance across its full operating temperature range (–55 °C to +175 °C).
Can the P4KE7.5AHE3/54 be used in bidirectional signal lines?
No, the P4KE7.5AHE3/54 is strictly unidirectional and unsuitable for bidirectional signal lines such as RS-485, CAN, or USB D+/D– without additional circuitry. Bidirectional protection requires symmetric clamping in both polarities, which the P4KE7.5AHE3/54 cannot provide. For such applications, Vishay specifies CA-suffix parts (e.g., P4KE7.5CA). Using the P4KE7.5AHE3/54 on bidirectional lines risks forward conduction during negative transients and potential damage to the protected interface.
