Product details
Overview
P6SMB27AHE3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 23.1 V stand-off voltage (VWM), 25.7–28.4 V breakdown voltage (VBR) at 1 mA, 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 protection.
For engineers reviewing the P6SMB27AHE3/52 datasheet, P6SMB27AHE3/52 pinout, P6SMB27AHE3/52 application, or P6SMB27AHE3/52 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 150 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a clamping device that remains high-impedance below VWM = 23.1 V and rapidly transitions to low-impedance conduction above VBR = 25.7–28.4 V to limit transient overvoltage. Its glass-passivated junction ensures stable breakdown characteristics and long-term reliability under repetitive surge stress.
The device delivers 37.5 V clamping at 16.0 A (10/1000 µs), with thermal resistance RθJA = 100 °C/W and RθJL = 20 °C/W, enabling effective heat dissipation in compact PCB layouts. It meets MSL Level 1 per J-STD-020 and supports lead-free reflow up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 23.1 V - Maximum continuous reverse operating voltage before significant leakage; defines safe operating margin for protected circuitry. |
| VBR (Breakdown) | 25.7–28.4 V at 1 mA - Voltage range at which device enters avalanche conduction; tight tolerance enables precise overvoltage thresholding. |
| VC (Clamping) | 37.5 V at 16.0 A (10/1000 µs) - Peak voltage seen by downstream IC during worst-case surge; determines survivability of protected MOSFET or MCU I/O. |
| PPPM | 600 W - Peak transient power handling capability; sufficient for ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 Level 3 surges. |
