Product details
Overview
P6KE160CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in DC power rails and signal lines. It features a 136 V standoff voltage (VWM), 152–168 V breakdown range (VBR at 1 mA), 219 V maximum clamping voltage (VC) at 2.7 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive sensor interfaces, industrial I/O modules, and telecom line protection.
For engineers reviewing the P6KE160CA-E3/54 datasheet, P6KE160CA-E3/54 pinout, P6KE160CA-E3/54 application, or P6KE160CA-E3/54 equivalent, key selection criteria include bidirectional clamping symmetry, DO-15 package thermal resistance (RθJL = 20 °C/W), AEC-Q101 qualification status, 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 136 V), then rapidly avalanches below 152 V to limit transient energy. Its glass-passivated junction ensures stable VBR tolerance (±5 %) and low temperature coefficient (0.108 %/°C), critical for repeatable clamping across -55 °C to +175 °C operating range.
Designed for unidirectional and bidirectional configurations, P6KE160CA-E3/54 delivers symmetrical electrical characteristics in both directions - including identical VBR, VC, and leakage (<1 µA at VWM) - enabling direct replacement of legacy bidirectional TVS devices without polarity-aware layout changes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 136 V - Maximum continuous reverse working voltage before significant leakage; defines safe operating margin for 120 V AC-derived DC rails. |
| VBR (min/max) | 152 V / 168 V at 1 mA - Tight 5 % tolerance ensures predictable turn-on across production lots and temperature. |
| VC @ IPPM | 219 V at 2.7 A (10/1000 µs) - Clamping voltage directly limits downstream IC stress during ESD or lightning-induced surges. |
| PPPM | 600 W - Sustains single high-energy transients common in automotive load-dump (ISO 7637-2 Pulse 5a) and industrial switching events. |
| ID @ VWM | <1 µA - Negligible standby power loss and minimal signal distortion in high-impedance sensor bias networks. |
| TJ max. | +175 °C - Enables placement near hot components (e.g., power MOSFETs, motor drivers) without derating concerns. |
| RθJL | 20 °C/W - Low junction-to-lead thermal resistance supports reliable power dissipation without heatsinking in DO-15 footprint. |
Pinout & Package
Package: DO-15 (DO-204AC) - axial-leaded, molded epoxy case meeting UL 94 V-0; matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 1A whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (unmarked) | Bidirectional terminal pair | No polarity marking required; symmetric conduction enables installation without orientation check in PCB layout. |
| Lead 1 / Lead 2 | Current path terminals | Leads serve as both mechanical anchor and thermal path; RθJL = 20 °C/W confirms effective heat transfer to PCB copper. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150CA | DO-214AA package; lower 150 V VWM; 600 W rating; higher IPPM (3.3 A); RθJA = 40 °C/W vs. 75 °C/W for P6KE160CA-E3/54 | Surface-mount alternative for space-constrained PCBs; less suitable for high-temperature ambient due to higher thermal resistance. | Select SMBJ150CA only when board real estate prohibits axial DO-15 and thermal management includes localized airflow or copper pour. |
| 1.5KE150CA | Same DO-15 package; 150 V VWM; 1500 W PPPM; larger die size; higher VC (243 V); non-AEC-Q101 rated | Higher-power alternative for infrequent but extreme surges; lacks automotive qualification and UL recognition. | Choose 1.5KE150CA only for non-automotive industrial applications where 1500 W headroom outweighs certification and leakage trade-offs. |
Compared with SMBJ150CA and 1.5KE150CA, P6KE160CA-E3/54 uniquely balances AEC-Q101 qualification, UL 497B recognition, and precise 136 V standoff - making it optimal for certified automotive and telecom designs where reliability, safety compliance, and parameter accuracy are non-negotiable.

FAQ
What is the standoff voltage (VWM) of P6KE160CA-E3/54, and why does it matter?
The P6KE160CA-E3/54 has a 136 V standoff voltage (VWM), meaning it remains non-conductive up to this DC or RMS voltage. This value ensures reliable operation on 120 V AC-derived DC rails while maintaining >1 µA leakage - critical for preserving signal integrity in high-impedance sensor circuits and avoiding false triggers in monitoring ICs. Exceeding VWM risks premature conduction and accelerated aging.
Is P6KE160CA-E3/54 suitable for automotive applications?
Yes - P6KE160CA-E3/54 is AEC-Q101 qualified and UL 497B recognized, validating its use in automotive subsystems such as body control modules, ADAS sensor interfaces, and infotainment power supplies. Its 175 °C max junction temperature, glass-passivated junction, and tested robustness against thermal cycling and humidity make it appropriate for under-hood and cabin environments per ISO 16750-4.
How does the clamping voltage (VC) of P6KE160CA-E3/54 compare to its breakdown voltage (VBR)?
P6KE160CA-E3/54 has a VBR range of 152–168 V at 1 mA and a maximum clamping voltage (VC) of 219 V at 2.7 A (10/1000 µs). The clamping ratio (VC/VBRmin) is ~1.44, indicating tight voltage control during surge events - essential for protecting 200 V-rated MOSFETs and ensuring downstream ICs experience no more than 219 V under worst-case transient conditions.
What package type does P6KE160CA-E3/54 use, and what are its thermal characteristics?
P6KE160CA-E3/54 uses the DO-15 (DO-204AC) axial package with matte tin-plated leads. Its thermal resistance is RθJL = 20 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient). This allows direct soldering to PCB copper without heatsinks while sustaining 5.0 W continuous power dissipation at lead temperature ≤75 °C - ideal for compact, thermally constrained layouts.
Does P6KE160CA-E3/54 have polarity markings, and how is it installed?
No - P6KE160CA-E3/54 is a bidirectional TVS and carries no cathode band or polarity marking. It installs identically in either orientation across protected lines (e.g., between VCC and GND, or across differential pairs), simplifying assembly and eliminating orientation-related solder defects. Electrical behavior is identical regardless of lead direction due to symmetrical avalanche structure.
