Product details
Overview
BZW04P10B-E3/54 from Vishay General Semiconductor is a bi-directional TransZorb® transient voltage suppressor (TVS) diode designed for robust overvoltage protection on signal and power lines. It features a 10.2 V stand-off voltage (VWM), 16.7 V maximum clamping voltage (VC) at 24.0 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the BZW04P10B-E3/54 datasheet, BZW04P10B-E3/54 pinout, BZW04P10B-E3/54 application, or BZW04P10B-E3/54 equivalent, key selection criteria include its bi-directional symmetry, AEC-Q101 qualification, DO-41 package compatibility, low 0.078 %/°C VBR temperature coefficient, and verified 1.0 µA reverse leakage at VWM.
Technical Context
This bi-directional TVS operates symmetrically in both polarities, with breakdown voltage (VBR) specified between 11.4 V and 13.2 V at 1.0 mA test current. Its clamping performance is characterized under standardized 10/1000 µs surge conditions, delivering consistent VC ≤ 16.7 V up to IPPM = 24.0 A.
The device uses a glass-passivated junction and meets UL 94 V-0 flammability requirements in its DO-204AL (DO-41) molded epoxy package. It is rated for continuous operation from –55 °C to +175 °C junction temperature and qualified to AEC-Q101 for automotive reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10.2 V - maximum steady-state reverse voltage before conduction begins; defines safe operating margin below breakdown |
| VBR (min/max) | 11.4 V / 13.2 V at 1.0 mA - ensures reliable turn-on within tight tolerance for predictable surge response |
| VC @ IPPM | 16.7 V at 24.0 A - limits downstream voltage during 10/1000 µs transients to protect 15 V-rated ICs |
| PPPM | 400 W - peak surge power handling capability with 0.01 % duty cycle; supports repetitive ESD/lightning surges |
| IPPM | 24.0 A - peak pulse current capacity under standard 10/1000 µs waveform; enables protection of medium-energy lines |
| TJ max. | +175 °C - high-temperature junction rating allows use in under-hood automotive and industrial environments |
| Temp. Coeff. VBR | 0.078 %/°C - low drift ensures stable clamping across wide ambient ranges without derating penalties |
Pinout & Package
Package: DO-204AL (DO-41), axial leaded, molded epoxy case with matte tin-plated leads compliant to J-STD-002 and JESD22-B102. No polarity marking - bi-directional symmetry eliminates orientation concerns during placement.
