Product details
Overview
P4KE160HE3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for robust overvoltage protection of sensitive electronics. It features a 136 V standoff voltage (VWM), 152–168 V breakdown range (VBR at 1 mA), 219 V maximum clamping voltage (VC) at 1.8 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive power line and industrial sensor interface protection.
For engineers reviewing the P4KE160HE3/73 datasheet, P4KE160HE3/73 pinout, P4KE160HE3/73 application, or P4KE160HE3/73 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, DO-41 mechanical data, clamping performance under surge conditions, and direct alternatives for ESD/transient-hardened designs.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR, it avalanches to divert transient energy away from downstream circuitry. Its glass-passivated junction ensures stable breakdown and low leakage (<1.0 μA at 136 V), while the unidirectional polarity (cathode-banded) enables DC-biased rail protection without forward conduction interference.
Thermal design is constrained by RθJA = 100 °C/W and RθJL = 66 °C/W, supporting operation up to +175 °C junction temperature. The device meets JESD 22-B106 solderability (275 °C, 10 s) and JESD 201 Class 2 whisker resistance, confirming suitability for automotive-grade reflow and long-term reliability.
Key Specifications

Applications
| Automotive Power Line Protection | Industrial Sensor Interface |
|---|---|
Use Scenario: Protecting 12 V supply rails in BCM modules against load dump and alternator transients per ISO 7637-2. IC Role / Device Role / Timing Role: Shunt-type transient suppressor placed between battery rail and local regulator input.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150A | DO-214AA package; 150 V VWM, 243 V VC @ 1.64 A; 600 W PPPM. | Higher clamping voltage but superior power density; requires PCB layout change due to SMC footprint. | Select when higher surge margin is needed and board space allows surface-mount rework. |
| 1.5KE150A | DO-201AD package; same VWM/VBR range but 1.5 kW PPPM; larger body, higher IFSM (125 A). | Designed for higher-energy transients (e.g., 10/1000 μs >500 W); not AEC-Q101 qualified. | Prefer for industrial mains-input protection where automotive qualification is unnecessary. |
Compared with SMBJ150A and 1.5KE150A, the P4KE160HE3/73 offers AEC-Q101 validation and DO-41 through-hole compatibility - critical for legacy automotive harness assemblies and repair-friendly field replacements - while delivering precise 136 V standoff and 219 V clamping within its 400 W rating.

FAQ
What is the standoff voltage (VWM) of the P4KE160HE3/73?
The P4KE160HE3/73 has a standoff voltage VWM of 136 V, meaning it remains non-conductive up to this reverse DC voltage. This value ensures compatibility with nominal 12 V and 24 V automotive and industrial systems while providing sufficient margin below the 152–168 V breakdown range. Exceeding VWM initiates controlled avalanche clamping.
Is the P4KE160HE3/73 AEC-Q101 qualified?
Yes, the P4KE160HE3/73 is explicitly AEC-Q101 qualified, as confirmed in Vishay Document 88365 (Rev. 16-Sep-2021), Note (1) under Ordering Information. The HE3 suffix denotes RoHS-compliant construction with JESD 201 Class 2 whisker resistance - fulfilling automotive reliability requirements for under-hood and chassis-mounted electronics.
What is the maximum clamping voltage (VC) for the P4KE160HE3/73?
The P4KE160HE3/73 exhibits a maximum clamping voltage VC of 219 V at 1.8 A peak pulse current (IPPM) under the standardized 10/1000 μs waveform. This parameter defines the upper voltage limit imposed on protected circuitry during surge events and is critical for ensuring downstream components remain within their absolute maximum ratings.
Does the P4KE160HE3/73 have bidirectional capability?
No, the P4KE160HE3/73 is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. Bidirectional variants use the "CA" suffix (e.g., P4KE160CA). Unidirectional operation allows optimal clamping on DC-biased lines while avoiding forward conduction during normal operation - essential for protecting regulated power rails.
What package type does the P4KE160HE3/73 use?
The P4KE160HE3/73 uses the DO-41 (DO-204AL) axial-leaded package, featuring a molded epoxy body over a glass-passivated chip, UL 94 V-0 flammability rating, and matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. Its 9.5 mm lead length and 5.2 mm body diameter align with legacy through-hole assembly standards.
