Product details
Overview
P6KE27CHE3/73 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for primary overvoltage protection of DC power rails and signal lines. It features 600 W peak pulse power (10/1000 μs), 25.7 V minimum breakdown voltage (VBR), 23.1 V stand-off voltage (VWM), and clamps to ≤37.5 V at 16.0 A peak pulse current - used in automotive ECU input protection and industrial sensor interface circuits.
For engineers reviewing the P6KE27CHE3/73 datasheet, P6KE27CHE3/73 pinout, P6KE27CHE3/73 application, or P6KE27CHE3/73 equivalent, key selection criteria include verified clamping performance under 10/1000 μs surge, AEC-Q101 qualification status, thermal resistance (RθJL = 20 °C/W), and RoHS-compliant matte tin plating per J-STD-002.
Technical Context
This device operates as a voltage-clamped shunt protector: when reverse voltage exceeds VWM (23.1 V), it transitions from high-impedance blocking to low-impedance conduction at VBR ≥25.7 V, limiting transient energy with <37.5 V clamping at 16.0 A. Its glass-passivated junction ensures stable breakdown and fast response (<1 ns).
Rated for 175 °C maximum junction temperature and 100 A non-repetitive forward surge (8.3 ms half-sine), it supports robust protection in automotive and industrial environments where inductive switching transients occur. The HE3 suffix confirms AEC-Q101 qualification and JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 23.1 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 μA; defines safe DC rail margin. |
| VBR (min) | 25.7 V at 1.0 mA test current - guaranteed turn-on threshold for transient detection and clamping initiation. |
| VC | ≤37.5 V at 16.0 A IPPM - maximum clamped voltage during 10/1000 μs surge; determines protected circuit's worst-case overvoltage. |
| PPPM | 600 W - peak pulse power handling capability with 10/1000 μs waveform; enables suppression of high-energy transients. |
| RθJL | 20 °C/W - junction-to-lead thermal resistance; supports 5.0 W steady-state dissipation at TL = 75 °C with minimal heatsinking. |
| IFSM | 100 A - peak forward surge current rating (8.3 ms half-sine); validates robustness against accidental polarity reversal events. |
| TJ max | 175 °C - maximum junction temperature; enables operation in under-hood automotive and high-ambient industrial settings. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24A | DO-214AA package; 24 V VWM, 26.7 V VBR min, 38.9 V VC at 15.4 A; 600 W rating same. | Surface-mount footprint; higher thermal resistance (RθJA ≈ 40 °C/W vs. 20 °C/W for P6KE27CHE3/73); less suited for high-ambient through-hole designs. | Select SMBJ24A only when PCB space constraints require SMD mounting and thermal management permits higher junction rise. |
| 1.5KE27A | Same DO-204AC package; 23.1 V VWM, 25.7 V VBR min, but 40.5 V VC at 14.8 A; 1500 W rating (10/1000 μs). | Higher clamping voltage increases stress on protected ICs; larger package volume; not AEC-Q101 qualified (E3 only). | Choose 1.5KE27A only for non-automotive applications requiring higher single-pulse energy absorption and where clamping margin allows. |
Compared with SMBJ24A and 1.5KE27A, P6KE27CHE3/73 delivers tighter clamping (37.5 V vs. 38.9 V/40.5 V), AEC-Q101 qualification for automotive use, and superior thermal performance via lower RθJL, making it optimal for space-constrained yet thermally demanding through-hole deployments.

FAQ
What is the clamping voltage of P6KE27CHE3/73 at its rated peak pulse current?
The P6KE27CHE3/73 clamps to a maximum of 37.5 V when subjected to its specified 16.0 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured at the device terminals and represents the upper limit of voltage seen by downstream circuitry during surge events - critical for ensuring compatibility with 3.3 V or 5 V logic interfaces and power management ICs. The clamping voltage is guaranteed across the full operating temperature range.
Is P6KE27CHE3/73 suitable for automotive applications?
Yes, P6KE27CHE3/73 is explicitly AEC-Q101 qualified (confirmed by the HE3 suffix), meaning it has passed rigorous stress tests including high-temperature operating life, temperature cycling, and highly accelerated stress testing. It is widely deployed in automotive engine control units, body electronics, and infotainment systems for protecting 12 V and 24 V power rails against ISO 7637-2 transients. Its 175 °C maximum junction temperature rating further supports under-hood deployment.
What does the "HE3" suffix indicate in P6KE27CHE3/73?
The "HE3" suffix in P6KE27CHE3/73 denotes two key qualifications: RoHS compliance (per Directive 2011/65/EU) and AEC-Q101 qualification for automotive use. Additionally, it specifies JESD 201 Class 2 whisker resistance for matte tin-plated leads - essential for long-term reliability in high-vibration, high-temperature environments. This distinguishes it from commercial-grade "E3" variants lacking automotive validation.
How does P6KE27CHE3/73 differ from P6KE27A-E3/73?
P6KE27CHE3/73 and P6KE27A-E3/73 share identical electrical specifications (VWM = 23.1 V, VBR ≥25.7 V, VC ≤37.5 V), DO-204AC packaging, and RoHS compliance. The critical difference lies in qualification: P6KE27CHE3/73 carries AEC-Q101 certification (HE3), while P6KE27A-E3/73 is commercial-grade (E3) without automotive validation. Both meet JESD 201 whisker requirements, but only HE3 is approved for automotive safety-critical subsystems.
What is the maximum reverse leakage current for P6KE27CHE3/73 at its stand-off voltage?
At its 23.1 V stand-off voltage (VWM) and TA = 25 °C, the P6KE27CHE3/73 exhibits a maximum reverse leakage current (ID) of 1.0 μA. This low leakage ensures minimal power loss in always-on circuits and prevents false triggering in high-impedance sensor bias networks. Leakage remains below 5.0 μA up to 85 °C ambient, supporting reliable operation across industrial temperature ranges.
