Product details
Overview
P4KE160C from Taiwan Semiconductor is a unidirectional 400W transient voltage suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 160V nominal breakdown voltage (VBR min/max: 144V–176V), 130V working stand-off voltage (VWM), clamps to ≤230V at 1.8A peak pulse current, and delivers sub-nanosecond response (<1.0ps from 0V to VBR). It is used in automotive body control modules to protect CAN transceivers from load dump and ISO 7637-2 pulses.
For engineers reviewing the P4KE160C datasheet, P4KE160C pinout, P4KE160C application, or P4KE160C equivalent, key selection criteria include clamping voltage margin vs. protected IC's absolute maximum rating, VWM derating for temperature and tolerance, unidirectional polarity marking, DO-41 mechanical fit, and AEC-Q101 qualification status for automotive deployment.
Technical Context
The P4KE160C operates as a silicon avalanche diode with sharp reverse-breakdown knee and low dynamic impedance. Its 400W peak pulse power rating is specified at the standard 10/1000μs double-exponential waveform per ANSI/IEEE C62.35, and it maintains stable VBR across temperature with a +0.108%/°C coefficient.
It exhibits <1μA reverse leakage at 130V (VWM), ensuring minimal standby power loss in high-impedance circuits. The device is unidirectional only - cathode band marking defines polarity - and is not rated for bidirectional use; bipolar variants require "CA" suffix (e.g., P4KE160CA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous DC or RMS voltage the device blocks without significant leakage; must be ≥15% below protected circuit's max operating voltage. |
| VBR @ IT=1mA | 144–176 V - Measured breakdown range at 1mA test current; defines minimum overvoltage threshold before clamping initiates. |
| VC @ IPPM=1.8A | ≤230 V - Clamped voltage during 10/1000μs surge; determines worst-case stress on downstream ICs (e.g., must be < IC's 250V abs max). |
| PPK | 400 W - Peak pulse power handling per single 10/1000μs event; derates linearly above 25°C ambient per Fig.2. |
| IR @ VWM | <1 μA - Reverse leakage at stand-off voltage; ensures negligible current draw in battery-powered or high-impedance sensor interfaces. |
| TJ max | +175 °C - Maximum junction temperature; enables operation in under-hood automotive environments without thermal shutdown. |
| Package | DO-204AL (DO-41) - Axial-leaded through-hole package with tin-plated leads; compatible with wave soldering and meets JESD201 Class 2 whisker resistance. |
Pinout & Package
DO-204AL (DO-41) axial package: Cathode indicated by colored band; anode and cathode terminals are non-polarized in layout but functionally asymmetric - cathode connects to protected line, anode to ground for unidirectional clamping.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Protected Line Connection | Connected to the node requiring overvoltage protection (e.g., CAN_H rail); conducts avalanche current to ground when V > VBR. |
| Anode (unbanded end) | Reference/Ground Return | Connected to system ground or low-impedance return path; completes clamping loop and defines unidirectional conduction direction. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including temperature cycling, humidity bias, and mechanical shock per stress test requirements. |
| 400W 10/1000μs surge rating | Withstands ISO 7637-2 Pulse 1 (−150V/50Ω) and Pulse 5a (load dump up to 60V) without degradation when properly heatsinked. |
| Clamping ratio VC/VBR ≈ 1.6 | Low ratio ensures tight voltage limiting - e.g., clamps at 230V while breaking down no later than 144V, giving robust design margin. |
| Sub-1.0ps response time | Activates before most ESD events fully develop, protecting sensitive inputs such as LIN or CAN transceiver pins from damage. |
| UL 94V-0 molding compound | Flame-retardant epoxy housing prevents fire propagation in enclosed automotive junction boxes or lighting housings. |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ160A | Same DO-214AC (SMA) package; 160V VBR, 230V VC, but lower 400W rating applies only at 25°C (derates faster above 75°C). | Surface-mount only; requires PCB rework for through-hole legacy designs; better thermal performance with copper pour but no axial lead option. | Select when board space is constrained and reflow assembly is available; verify thermal pad layout matches SMA footprint. |
| ON Semiconductor 1.5KE160A | Higher 1500W rating but larger DO-201AD (Axial) package; identical VBR/VC specs but 2.5× heavier (1.1g vs. 0.3g) and longer body (9.5mm vs. 5.2mm). | Used where higher single-pulse energy is needed (e.g., railway traction systems); incompatible with DO-41 socket or automated axial insertion equipment. | Choose only if surge energy exceeds 400W requirement; otherwise, P4KE160C offers optimal size/power density for automotive and industrial PCBs. |
Compared with SMAJ160A and 1.5KE160A, P4KE160C provides the best balance of compact DO-41 form factor, AEC-Q101 qualification, and verified 400W capability - making it preferred for space-constrained, high-reliability automotive ECUs and industrial controllers where axial mounting and proven qualification are mandatory.

FAQ
What is the polarity configuration of the P4KE160C?
The P4KE160C is a unidirectional TVS diode with cathode marked by a colored band. It conducts only when the cathode is at a higher potential than the anode - meaning it clamps positive transients on a line referenced to ground. It must not be used for bidirectional protection; for that, the P4KE160CA variant is required. The P4KE160C datasheet explicitly states "Devices for bipolar applications" require the "C or CA suffix", confirming P4KE160C is strictly unidirectional.
Does the P4KE160C meet AEC-Q101 qualification?
Yes, the P4KE160C is AEC-Q101 qualified, as confirmed in the "FEATURES" section of the official Taiwan Semiconductor datasheet (Version N2104). This qualification covers stress tests including temperature cycling, high-temperature operating life, and mechanical shock - validating its suitability for automotive under-hood and cabin applications. Note that AEC-Q101 status applies to the base P4KE160C part number, not just "H"-suffixed variants.
What is the maximum clamping voltage of the P4KE160C at its rated peak pulse current?
The P4KE160C has a maximum clamping voltage (VC) of 230 V at its rated peak pulse current (IPPM) of 1.8 A, tested under the standard 10/1000μs waveform. This value is guaranteed across the full operating temperature range and represents the worst-case voltage seen by downstream components during surge events - critical for ensuring protected ICs remain within their absolute maximum ratings.
Can the P4KE160C be used in bidirectional signal line protection?
No, the P4KE160C is unidirectional only and unsuitable for bidirectional signal lines like RS-485 or USB D+/D−. Its electrical characteristics apply in one direction only, and reverse conduction is not characterized or guaranteed. For bidirectional protection, the P4KE160CA variant must be used - it features symmetrical breakdown in both directions and is explicitly designated for bipolar applications in the datasheet.
What is the reverse leakage current specification for the P4KE160C at its working stand-off voltage?
The P4KE160C exhibits a maximum reverse leakage current (ID) of 1 μA at its working stand-off voltage (VWM) of 130 V, measured at 25°C. This ultra-low leakage ensures minimal power loss in always-on circuits such as automotive wake-up receivers or battery-backed sensors, preserving system efficiency without compromising protection integrity.
