Product details
Overview
P4KE7.5C-E3/73 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 7.13 V to 7.88 V breakdown voltage (VBR) at 10 mA test current, 6.40 V standoff voltage (VWM), and clamps to ≤11.3 V at 35.4 A peak pulse current (IPPM) under 10/1000 μs waveform - used in automotive sensor line protection and industrial I/O interface surge suppression.
For engineers reviewing the P4KE7.5C-E3/73 datasheet, P4KE7.5C-E3/73 pinout, P4KE7.5C-E3/73 application, or P4KE7.5C-E3/73 equivalent, key selection criteria include bidirectional clamping capability, 400 W peak pulse power rating, low clamping ratio (VC/VBR ≈ 1.43), AEC-Q101 qualification, and DO-41 leaded package compatibility with through-hole PCB assembly.
Technical Context
The P4KE7.5C-E3/73 implements a glass-passivated PN junction optimized for fast transient response (<1 ns) and low incremental surge resistance. Its bidirectional architecture enables symmetrical clamping in AC-coupled or floating signal paths without polarity constraints.
It operates across -55 °C to +175 °C junction temperature range, supports 1.5 W steady-state power dissipation at TL = 75 °C, and maintains stable VBR temperature coefficient of +0.061 %/°C - critical for thermal stability in under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.13 V / 7.88 V at 10 mA - defines reliable conduction onset threshold for transient suppression |
| VWM | 6.40 V - maximum continuous reverse operating voltage before leakage exceeds 500 μA |
| VC @ IPPM | ≤11.3 V at 35.4 A - clamped voltage during 400 W 10/1000 μs surge, limiting downstream stress |
| PPPM | 400 W - peak pulse power handling per single transient event, compliant with IEC 61000-4-5 Level 4 |
| IFSM | Not applicable - bidirectional device has no forward surge rating; only unidirectional variants specify 40 A |
| TJ max. | +175 °C - enables use in high-temperature engine control units and industrial motor drives |
| Package | DO-41 (DO-204AL) - axial-leaded, UL 94 V-0 molded epoxy case for manual or wave soldering |
Pinout & Package
DO-41 (DO-204AL) package: axial-leaded, glass-passivated silicon junction in flame-retardant epoxy body; leads are matte tin-plated, solderable per J-STD-002 and JESD 22-B102; no polarity marking for bidirectional types.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction terminals | No functional distinction - either lead serves as input/output for transient energy diversion in both directions |
| Lead 1 / Lead 2 | Current path for surge conduction | Leads conduct clamped current to ground or rail; RθJL = 66 °C/W enables thermal management via PCB copper pour or heatsink contact |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables stable VBR tolerance and long-term reliability under repeated surge stress |
| 400 W peak pulse power (10/1000 μs) | Meets IEC 61000-4-5 surge immunity requirements for industrial and automotive electronics |
| AEC-Q101 qualified | Validated for automotive under-hood applications including engine control, body electronics, and ADAS sensors |
| Low clamping ratio (VC/VBR ≈ 1.43) | Minimizes overvoltage exposure to protected ICs such as CAN transceivers or microcontrollers |
| UL 94 V-0 flammability rating | Ensures flame resistance during catastrophic failure modes in safety-critical systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0CA | Surface-mount SMB package; 7.0 V VWM, 7.78 V VBR min, 12.5 V VC @ 32.8 A; 600 W PPPM | Higher power rating but larger footprint; requires rework for SMT-only boards | Select when board space allows SMT and higher surge margin is required |
| 1.5KE7.5C | Same DO-41 package; 7.5 V VWM, 8.33 V VBR min, 12.0 V VC @ 33.3 A; 1500 W PPPM | Higher clamping voltage and 3.75× peak power - suited for heavy-duty industrial mains protection | Select when legacy 1.5KE footprint compatibility is mandatory and higher surge levels expected |
Compared with P4KE7.5C-E3/73, SMBJ7.0CA offers superior power handling in SMT form but lacks AEC-Q101 qualification, while 1.5KE7.5C delivers greater robustness in identical through-hole packaging but increases clamping voltage by 0.7 V - impacting sensitive 3.3 V logic interfaces.

FAQ
What does the "C" suffix indicate in P4KE7.5C-E3/73?
The "C" suffix in P4KE7.5C-E3/73 denotes a bidirectional configuration, meaning the device provides symmetrical clamping in both polarities - essential for protecting AC-coupled or floating signal lines where voltage transients may swing positive or negative relative to ground. This differs from unidirectional "A" variants that require correct polarity orientation during placement.
Is P4KE7.5C-E3/73 AEC-Q101 qualified?
Yes, P4KE7.5C-E3/73 is AEC-Q101 qualified - confirmed by Vishay's documentation stating HE3-suffix parts are AEC-Q101 qualified, and E3/73 ordering code corresponds to commercial-grade RoHS-compliant version with AEC-Q101 qualification explicitly noted for P4KE7.5C-E3/73 in the mechanical data section and notes.
What is the maximum clamping voltage for P4KE7.5C-E3/73 under surge conditions?
The maximum clamping voltage (VC) for P4KE7.5C-E3/73 is 11.3 V at 35.4 A peak pulse current (IPPM) using the standard 10/1000 μs waveform. This value is measured per Figure 1 and Table on page 2 of Vishay document 88365 and defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
Can P4KE7.5C-E3/73 be used in place of a unidirectional TVS like P4KE7.5A-E3/73?
No - P4KE7.5C-E3/73 is bidirectional and lacks polarity marking, whereas P4KE7.5A-E3/73 is unidirectional with cathode band identification. Substitution requires verifying circuit topology: bidirectional use is mandatory for AC signals or floating grounds; unidirectional parts are required for DC-biased lines where reverse conduction must be blocked.
What is the standoff voltage (VWM) rating for P4KE7.5C-E3/73?
The standoff voltage (VWM) for P4KE7.5C-E3/73 is 6.40 V - the maximum DC or continuous AC voltage the device can withstand without exceeding 500 μA reverse leakage current. This ensures reliable operation on 5 V logic or sensor supply rails while maintaining sufficient margin below VBR to avoid false triggering.
