Product details
Overview
P4KE7.5-E3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in DO-41 package, designed for clamping inductive switching surges and ESD events on DC power rails and signal lines. It features 7.13 V minimum breakdown voltage (VBR), 6.40 V maximum standoff voltage (VWM), 11.3 V clamping voltage at 35.4 A peak pulse current (IPPM), and 400 W peak pulse power rating with 10/1000 μs waveform - used in automotive body control modules and industrial sensor interfaces.
For engineers reviewing the P4KE7.5-E3/54 datasheet, P4KE7.5-E3/54 pinout, P4KE7.5-E3/54 application, or P4KE7.5-E3/54 equivalent, key selection criteria include unidirectional polarity, DO-41 leaded package compatibility, 6.4 V working voltage margin, 11.3 V clamping performance under 35.4 A surge, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
This TVS diode operates as a voltage-clamping protection device that transitions from high-impedance standby to low-impedance conduction when reverse voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable leakage (<500 μA at VWM) and fast response time (<1.0 ns), enabling effective suppression of EFT bursts and lightning-induced transients.
The device sustains 400 W peak pulse power per 10/1000 μs waveform with derating above 25 °C, and handles up to 40 A non-repetitive forward surge (8.3 ms half-sine). Thermal resistance is 66 °C/W junction-to-lead, supporting reliable operation in ambient temperatures from –55 °C to +175 °C.
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 range for overvoltage detection |
| VWM | 6.40 V - maximum continuous reverse operating voltage before leakage rises significantly |
| VC @ IPPM | 11.3 V at 35.4 A - actual clamped voltage during worst-case 400 W transient, limiting downstream stress |
| IPPM | 35.4 A - peak surge current capability with 10/1000 μs waveform, directly tied to 400 W rating |
| PPPM | 400 W - standardized surge power handling per industry waveform, enabling direct comparison across TVS families |
| TJ max | +175 °C - maximum junction temperature supports under-hood automotive placement without derating penalties |
| Leakage ID | 500 μA at VWM - low standby current avoids battery drain in always-on systems |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with axial leads; cathode indicated by color band on one end; matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 1A whisker resistance.

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, 12.0 V VC @ 32.1 A, 400 W rating | Surface-mount alternative; higher thermal resistance (110 °C/W) limits power density in high-ambient designs | Select for automated SMT assembly where board space is constrained and leaded DO-41 is incompatible |
| 1N6267A | Same DO-41 package, 7.5 V VWM, 12.5 V VC @ 32.0 A, 400 W rating, no AEC-Q101 qualification | Lacks automotive qualification; higher clamping voltage increases risk to downstream 5 V ICs | Acceptable for cost-sensitive industrial controls where AEC-Q101 is not mandated |
Compared with SMBJ7.0A and 1N6267A, the P4KE7.5-E3/54 provides tighter clamping (11.3 V vs. ≥12.0 V), AEC-Q101 qualification for automotive use, and lower thermal resistance (66 °C/W) - making it optimal for thermally demanding, safety-critical placements.

FAQ
What is the polarity configuration of the P4KE7.5-E3/54?
The P4KE7.5-E3/54 is a unidirectional TVS diode, meaning it conducts only in reverse bias above its breakdown voltage. The cathode is marked by a color band on the DO-41 package body, and the anode connects to ground or lower potential. This configuration protects positive-rail circuits from negative-going transients and positive surges relative to ground.
Does the P4KE7.5-E3/54 meet automotive qualification standards?
Yes, the P4KE7.5-E3/54 is AEC-Q101 qualified, as confirmed in Vishay's official documentation (Document Number 88365, Revision 16-Sep-2021). This qualification validates its reliability for automotive applications including engine control, body electronics, and infotainment systems under extended temperature cycling, humidity, and mechanical stress conditions.
What is the clamping voltage of the P4KE7.5-E3/54 under surge conditions?
The P4KE7.5-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 per standard test conditions and represents the upper bound of voltage seen by protected circuitry during a full-power transient event.
Can the P4KE7.5-E3/54 be used in bidirectional protection applications?
No - the P4KE7.5-E3/54 is strictly unidirectional. For bidirectional protection, Vishay specifies the CA-suffix variant (e.g., P4KE7.5CA), which has symmetrical breakdown in both directions. Using the unidirectional P4KE7.5-E3/54 in AC or floating-line applications risks failure due to forward conduction during negative half-cycles.
What is the maximum steady-state power dissipation of the P4KE7.5-E3/54?
The P4KE7.5-E3/54 has a maximum steady-state power dissipation (PD) of 1.5 W when mounted on an infinite heatsink at lead temperature (TL) = 75 °C. In typical PCB mounting, derating applies per Figure 5 in the datasheet, with usable power dropping to ~0.8 W at TA = 70 °C.
