Product details
Overview
P6KE27AHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for primary overvoltage protection of DC power rails and signal lines. It features 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 - deployed in automotive sensor interfaces and industrial I/O modules.
For engineers reviewing the P6KE27AHE3/54 datasheet, P6KE27AHE3/54 pinout, P6KE27AHE3/54 application, or P6KE27AHE3/54 equivalent, this AEC-Q101 qualified TVS offers verified clamping performance, low leakage (<1.0 μA at VWM), and robust surge handling for ESD and load-dump transient suppression in space-constrained designs.
Technical Context
This unidirectional TVS operates by avalanche breakdown to clamp transient voltages above its VBR threshold while maintaining <1.0 μA reverse leakage at 23.1 V. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1.0 ns), enabling effective suppression of ESD (IEC 61000-4-2), EFT (IEC 61000-4-4), and inductive switching spikes.
Thermal design is supported by RθJL = 20 °C/W and RθJA = 75 °C/W, with rated operating junction temperature up to +175 °C and 100 A non-repetitive forward surge capability (8.3 ms half-sine). The device is RoHS-compliant and qualified to AEC-Q101 for automotive-grade reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 25.7 V / 28.4 V at 1.0 mA - defines precise avalanche initiation window for repeatable clamping onset |
| VWM | 23.1 V - maximum continuous DC or RMS voltage the device blocks without significant leakage |
| VC @ IPPM | 37.5 V at 16.0 A (10/1000 μs) - limits downstream voltage stress during worst-case transients |
| PPPM | 600 W - peak transient energy absorption capacity under standardized surge waveform |
| IPPM | 16.0 A - maximum non-repetitive surge current the device safely clamps without degradation |
| ID @ VWM | <1.0 μA - ensures negligible standby power loss and no interference with high-impedance circuits |
| TJ max. | +175 °C - enables operation in under-hood automotive and high-temperature industrial environments |
Pinout & Package
DO-15 (DO-204AC) molded epoxy package with axial leads; cathode indicated by color band on body. Matte tin-plated leads meet J-STD-002 solderability and JESD 201 Class 2 whisker resistance requirements. Package dimensions: 3.3–3.5 mm diameter × 6.15–6.55 mm length, lead spacing ≥25.4 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to circuit ground or lowest potential node; completes conduction path during reverse transient |
| Cathode | Protected line input | Connected to line being protected (e.g., 24 V rail or sensor output); avalanche occurs when voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units and body electronics with full temperature and life-cycle testing |
| Glass passivated junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity exposure |
| 600 W peak pulse power (10/1000 μs) | Handles high-energy transients such as ISO 7637-2 Pulse 1/2a/5a without failure or parameter shift |
| Fast response time (<1 ns) | Clamps before sensitive ICs experience overvoltage damage - critical for protecting CAN transceivers and microcontrollers |
| Low clamping ratio (VC/VBR ≈ 1.33) | Minimizes overvoltage margin required in system-level protection design, reducing need for additional buffering stages |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A | Lower PPPM (400 W), SMA package (smaller footprint, higher RθJA = 110 °C/W), VBR = 26.7–29.5 V | Better suited for PCB area-constrained consumer electronics; less thermal margin in high-ambient industrial use | Select when board space is limited and peak surge energy rarely exceeds 400 W |
| 1.5KE27A | Same DO-15 package, identical VBR/VC, but commercial-grade (non-AEC-Q101), 1.5 kW PPPM rating | Higher power handling but lacks automotive qualification and tighter process controls for automotive BOMs | Prefer for cost-sensitive industrial power supplies where AEC-Q101 is not mandated |
Compared with SMAJ24A and 1.5KE27A, P6KE27AHE3/54 delivers AEC-Q101 assurance and optimized thermal resistance (RθJL = 20 °C/W) for sustained surge duty in automotive and harsh-environment applications - making it the preferred choice where reliability validation and junction temperature control are critical.

FAQ
What is the clamping voltage of P6KE27AHE3/54 at its rated peak pulse current?
The P6KE27AHE3/54 has a maximum clamping voltage (VC) of 37.5 V when subjected to its rated 16.0 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is guaranteed across temperature and production lots per Vishay's datasheet specification 88369, ensuring predictable overvoltage limiting for downstream components in the protected circuit.
Is P6KE27AHE3/54 suitable for automotive applications?
Yes, P6KE27AHE3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its +175 °C maximum junction temperature, glass-passivated junction, and validated surge performance per ISO 7637-2 make it appropriate for engine control, body electronics, and ADAS sensor protection - confirmed in Vishay's qualification report referenced in document 88369.
How does the HE3 suffix differ from E3 in P6KE27AHE3/54?
The HE3 suffix in P6KE27AHE3/54 indicates AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas E3 denotes commercial-grade RoHS compliance only. Both share identical electrical specs and DO-15 packaging, but HE3 is required for automotive BOMs where reliability validation is mandatory - a distinction clearly defined in Vishay's ordering information table on page 3 of document 88369.
What is the maximum reverse leakage current for P6KE27AHE3/54 at its stand-off voltage?
At its 23.1 V stand-off voltage (VWM), the P6KE27AHE3/54 exhibits a maximum reverse leakage current (ID) of 1.0 μA at 25 °C, as specified in the Electrical Characteristics table of Vishay's datasheet 88369. This ultra-low leakage preserves signal integrity in high-impedance sensor and communication circuits without loading effects.
Can P6KE27AHE3/54 be used in bidirectional configurations?
No, P6KE27AHE3/54 is a unidirectional TVS diode, identifiable by its cathode band marking. Bidirectional variants require the "CA" suffix (e.g., P6KE27CA). Using P6KE27AHE3/54 in bidirectional applications would result in forward conduction during negative transients - violating its design intent and risking failure. Always match suffix to polarity requirement per Vishay's device naming convention.
