Product details
Overview
P6KE27CHE3/54 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for clamping voltage transients on signal or power lines. It features a 27 V breakdown voltage (VBR min/max = 25.7–28.4 V at 1.0 mA), 23.1 V stand-off voltage (VWM), 37.5 V maximum clamping voltage (VC) at 16.0 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6KE27CHE3/54 datasheet, P6KE27CHE3/54 pinout, P6KE27CHE3/54 application, or P6KE27CHE3/54 equivalent, this device delivers AEC-Q101 qualified surge protection with verified bi-directional clamping behavior, low thermal resistance (RθJL = 20 °C/W), and RoHS-compliant matte tin-plated leads suitable for J-STD-002 soldering.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, with identical electrical characteristics in forward and reverse directions. Its glass-passivated junction enables fast response time (<1 ns), low incremental surge resistance, and stable clamping under repetitive 10/1000 µs transients at 0.01% duty cycle.
The device is rated for -55 °C to +175 °C operating junction temperature, supports 100 A non-repetitive forward surge current (IFSM), and exhibits a 0.096 %/°C temperature coefficient of VBR, ensuring predictable voltage threshold drift over temperature in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 25.7 V / 28.4 V at 1.0 mA - defines reliable conduction onset under transient stress |
| VWM | 23.1 V - maximum continuous working voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 37.5 V at 16.0 A - clamped voltage during worst-case 600 W surge, limiting downstream stress |
| PPPM | 600 W - peak pulse power handling with 10/1000 µs waveform, enabling robust ESD/Lightning immunity |
| IPPM | 16.0 A - maximum non-repetitive surge current the device safely clamps without failure |
| TJ max. | +175 °C - high-temperature operation support for under-hood automotive or industrial power rails |
| RθJL | 20 °C/W - low junction-to-lead thermal resistance improves power dissipation reliability during repeated surges |
Pinout & Package
Package: DO-204AC (DO-15), molded epoxy case with matte tin-plated leads; bi-directional polarity - no cathode marking required.
| Pin/Terminal | Circuit Role | Design Meaning |

Use Scenario: Protecting analog front-end inputs of pressure/temperature sensors exposed to ESD and inductive switching noise in PLC I/O modules. IC Role / Device Role / Timing Role: Low-capacitance shunt protector across differential signal pairs (e.g., RS-485, 4–20 mA loops). Use Value: Maintains signal integrity with <1 pF junction capacitance at zero bias while clamping ±37.5 V surges without forward conduction. |
| Consumer Power Adapter Input Stage | Telecom DC Power Feeds |
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24CA | DO-214AA package; lower 400 W PPPM; VC = 38.9 V @ 10.3 A; higher VWM = 24 V | Better suited for space-constrained PCBs but requires derating for 600 W surge events | Select when board area is critical and peak surge energy is ≤400 W; verify thermal margin with RθJA = 50 °C/W |
| 1.5KE27CA | DO-201AD package; same 600 W rating; VC = 43.0 V @ 13.9 A; higher clamping voltage (+14.7%) | Higher clamping increases risk to downstream 3.3 V/5 V logic; less optimal for low-voltage IC protection | Choose only if legacy DO-201AD footprint must be retained; avoid where VC margin below IC abs max is <5 V |
Compared with SMBJ24CA and 1.5KE27CA, P6KE27CHE3/54 offers superior clamping efficiency (37.5 V vs. ≥38.9 V), AEC-Q101 qualification for automotive use, and optimized thermal resistance for sustained surge duty - making it preferred for high-reliability 12–24 V system protection.

FAQ
What does the 'HE3' suffix indicate in P6KE27CHE3/54?
The HE3 suffix in P6KE27CHE3/54 denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. This distinguishes it from the commercial-grade E3 variant and confirms suitability for automotive electronics where reliability under thermal and mechanical stress is mandatory. P6KE27CHE3/54 meets UL 94 V-0 flammability and supports soldering per J-STD-002.
Is P6KE27CHE3/54 uni-directional or bi-directional?
P6KE27CHE3/54 is a bi-directional TVS diode, as confirmed by the 'CA' designation in its full family name (P6KE27CA) and explicit documentation stating "electrical characteristics apply in both directions." It has no polarity marking and functions identically for positive and negative transients - unlike uni-directional variants such as P6KE27A which require cathode orientation.
What is the maximum clamping voltage of P6KE27CHE3/54 and at what current is it specified?
The maximum clamping voltage of P6KE27CHE3/54 is 37.5 V, measured at 16.0 A peak pulse current (IPPM) using a 10/1000 µs waveform. This value is guaranteed per the Vishay datasheet and defines the upper voltage limit imposed on protected circuits during worst-case surge events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Can P6KE27CHE3/54 replace P6KE27A in an existing design?
No - P6KE27CHE3/54 is bi-directional (P6KE27CA), while P6KE27A is uni-directional. Substituting them requires verifying circuit topology: P6KE27CHE3/54 may be used across differential lines or ungrounded rails, but cannot replace P6KE27A in single-ended, cathode-grounded configurations without risking improper clamping. Always confirm polarity requirements before interchange.
What is the thermal resistance from junction to lead (RθJL) for P6KE27CHE3/54?
The junction-to-lead thermal resistance (RθJL) for P6KE27CHE3/54 is 20 °C/W, as specified in the Vishay thermal characteristics table. This low value enables efficient heat transfer from the silicon die to the PCB copper via the leads, supporting reliable operation during repetitive surge events and contributing to the device's 175 °C maximum junction temperature rating.
