Product details
Overview
P6KE160CAHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features a 136 V standoff voltage (VWM), 152–168 V breakdown voltage (VBR) at 1 mA, 219 V maximum clamping voltage (VC) at 2.7 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform. It is AEC-Q101 qualified and used to protect MOSFETs and sensor signal lines in automotive ECUs.
For engineers reviewing the P6KE160CAHE3/54 datasheet, P6KE160CAHE3/54 pinout, P6KE160CAHE3/54 application, or P6KE160CAHE3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-15 mechanical compatibility, AEC-Q101 qualification status, thermal resistance (RθJL = 20 °C/W), and compliance with UL 497B surge protector classification.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at VWM), but switches to low-impedance conduction within <1 ns when transient voltage exceeds VBR. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1 μA at VWM).
The bidirectional structure enables symmetrical clamping in both polarities-critical for AC-coupled or floating signal lines-and eliminates need for polarity-aware placement. Its 175 °C max junction temperature and 20 °C/W junction-to-lead thermal resistance support reliable operation in thermally constrained automotive and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 136 V - Maximum continuous reverse voltage before significant leakage; defines safe operating window for protected circuit. |
| VBR (Breakdown Voltage) | 152–168 V at 1 mA - Confirmed breakdown threshold range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 219 V at IPPM = 2.7 A - Peak voltage seen by downstream circuit during 10/1000 μs surge; determines protection margin. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy-handling capacity per transient; validates suitability for IEC 61000-4-5 Level 4 surges. |
| RθJL (Junction-to-Lead) | 20 °C/W - Enables thermal design with lead-frame heat sinking; supports >5 W continuous dissipation at TL = 75 °C. |
| TJ max | 175 °C - Allows operation in under-hood automotive zones without derating below ambient +100 °C. |
| AEC-Q101 Qualified | Yes - Validated for automotive electronics per stress test requirements including HTOL, TCT, and ESD HBM ≥ 2 kV. |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, molded epoxy case meeting UL 94 V-0. Matte tin-plated leads, solderable per J-STD-002/JESD 22-B102. No polarity marking - bidirectional symmetry confirmed.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals function identically; no cathode band - simplifies PCB layout and eliminates orientation errors. |
| Leads (anode & cathode) | Thermal and electrical interface | Provide primary heat path to PCB copper; RθJL = 20 °C/W assumes 0.375" (9.5 mm) lead length per JEDEC standards. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable VBR over lifetime and temperature; prevents parameter drift in humid or high-bias stress environments. |
| 600 W peak pulse power (10/1000 μs) | Supports robust protection against lightning-induced surges and inductive switching spikes in 12 V/24 V systems. |
| AEC-Q101 qualification | Validates reliability for automotive powertrain, body control, and ADAS modules without additional qualification effort. |
| UL 497B recognized (QVGQ2) | Meets safety agency requirements for telecom and industrial surge protection devices; simplifies end-equipment certification. |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage stress on protected ICs - critical for 135 V-rated components like automotive CAN transceivers. |
Applications
| Automotive Body Control Module (BCM) | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Protecting LIN bus transceiver inputs from load-dump and jump-start transients in door module ECUs.

FAQ
What is the clamping voltage of P6KE160CAHE3/54 at its rated peak pulse current?
The P6KE160CAHE3/54 has a maximum clamping voltage (VC) of 219 V at 2.7 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88369 and defines the upper voltage limit imposed on protected circuitry during surge events.
Is P6KE160CAHE3/54 suitable for automotive applications?
Yes, P6KE160CAHE3/54 is AEC-Q101 qualified (note "HE3" suffix), tested for high-temperature operating life, temperature cycling, and ESD robustness. Its 175 °C max junction temperature and UL 497B recognition make it appropriate for under-hood and body control module deployments.
How does the bidirectional configuration of P6KE160CAHE3/54 affect circuit layout?
The P6KE160CAHE3/54 has no polarity marking and identical electrical behavior in both directions, eliminating orientation constraints during placement. This simplifies PCB assembly and enables use on AC-coupled or floating lines - such as LIN bus or differential sensor outputs - without risk of reverse installation.
