Product details
Overview
P4KE160CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on power and signal lines. It features 160 V breakdown voltage (VBR min/max = 152–168 V), 136 V stand-off voltage (VWM), 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 - used to protect MOSFETs and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P4KE160CA-E3/54 datasheet, P4KE160CA-E3/54 pinout, P4KE160CA-E3/54 application, or P4KE160CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-41 mechanical compatibility, AEC-Q101 qualification status, thermal resistance (RθJL = 66 °C/W), and leakage current ≤1.0 µA at VWM.
Technical Context
This device operates as a voltage-clamped surge protector with symmetrical avalanche behavior in both polarities, enabling protection of AC-coupled or floating signal paths without polarity concerns. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance under repetitive transient stress.
The P4KE160CA-E3/54 delivers 400 W peak pulse power handling per 10/1000 µs waveform at TA = 25 °C, derating linearly above 25 °C with 0.66%/°C slope, and supports operating junction temperatures from –55 °C to +175 °C - critical for under-hood automotive and high-temperature industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 152 V / 168 V at IT = 1.0 mA - defines reliable avalanche initiation range for bidirectional clamping |
| VWM | 136 V - maximum continuous reverse working voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 219 V at 1.8 A - clamped voltage during 10/1000 µs surge, limiting downstream IC stress |
| PPPM | 400 W - peak transient energy absorption capacity with standard lightning-surge waveform |
| IPPM | 1.8 A - maximum non-repetitive surge current the device sustains without failure |
| RθJL | 66 °C/W - thermal resistance from junction to lead, guiding heatsinking requirements for sustained duty |
| TJ max | +175 °C - maximum junction temperature, supporting operation in engine-control or motor-drive enclosures |
Pinout & Package
Package: DO-41 (DO-204AL), axial-leaded molded epoxy case with matte tin-plated leads; meets UL 94 V-0 flammability rating and J-STD-002 solderability standards. Bidirectional construction has no polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | No functional distinction between terminals; either lead serves as input/output for transient suppression |
| Lead 1 / Lead 2 | Current path for surge conduction | Leads conduct full IPPM during clamping; require ≥10 mm length for specified RθJA = 100 °C/W |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity |
| 400 W peak pulse power (10/1000 µs) | Supports IEC 61000-4-5 Level 4 surge immunity compliance in industrial power inputs |
| AEC-Q101 qualified | Validated for automotive applications including body electronics and powertrain sensor interfaces |
| Low leakage (≤1.0 µA at VWM) | Minimizes standby power loss in always-on circuits such as CAN bus nodes or battery monitors |
| UL 94 V-0 molding compound | Meets flame-retardancy requirements for enclosed industrial control cabinets and EV charging units |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160CA | Surface-mount SMB package (vs. through-hole DO-41); same VBR range and PPPM = 600 W | Requires PCB re-layout; better suited for high-density consumer electronics vs. legacy industrial chassis designs | Select when automated assembly and space constraints outweigh manual repairability needs |
| 1.5KE160CA | Higher PPPM = 1500 W; larger DO-201AD package; identical VBR, VC, and bidirectional function | Used where higher surge margin is mandated (e.g., outdoor telecom cabinets), but requires larger board area and higher cost | Choose when system-level surge testing exceeds IEC 61000-4-5 Level 4 and DO-41 thermal limits are insufficient |
Compared with SMBJ160CA and 1.5KE160CA, the P4KE160CA-E3/54 offers optimal balance of proven DO-41 mechanical robustness, AEC-Q101 qualification, and cost-effective 400 W surge handling - making it preferred for serviceable industrial controls and automotive subsystems where through-hole mounting and long-term supply stability are prioritized.

FAQ
What is the breakdown voltage tolerance for P4KE160CA-E3/54?
The P4KE160CA-E3/54 has a minimum breakdown voltage (VBR) of 152 V and a maximum of 168 V at test current IT = 1.0 mA. This ±5.6% tolerance ensures consistent clamping behavior across production lots while accommodating thermal drift within its –55 °C to +175 °C operating range.
Is P4KE160CA-E3/54 suitable for automotive applications?
Yes, the P4KE160CA-E3/54 carries AEC-Q101 qualification (per note on page 3 of Vishay document 88365), confirming its suitability for automotive use cases including engine control units, body electronics, and sensor interface protection where reliability under thermal cycling and vibration is required.
Does P4KE160CA-E3/54 have polarity markings?
No, the P4KE160CA-E3/54 is a bidirectional TVS diode and carries no color band or other polarity marking. Its symmetrical construction allows installation in either orientation across protected lines - essential for AC signal paths and floating differential interfaces.
What is the maximum clamping voltage of P4KE160CA-E3/54 under surge conditions?
The P4KE160CA-E3/54 exhibits a maximum clamping voltage (VC) of 219 V when subjected to its rated peak pulse current (IPPM = 1.8 A) using the standard 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during transient events.
How does the thermal resistance of P4KE160CA-E3/54 affect PCB layout?
The P4KE160CA-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W. To maintain safe junction temperature, PCB traces connected to its leads must provide adequate copper area and thermal relief; Vishay specifies 10 mm lead length for the published RθJA = 100 °C/W rating.
