BZW04-28B Description

Short technical summary and product information.

The BZW04-28B is a bidirectional Transient Voltage Suppressor (TVS) diode from STMicroelectronics, designed for general purpose overvoltage protection. It features a stand-off voltage of 28.2V, a breakdown voltage range of 28.2V to 31.4V, and a maximum clamping voltage of 45.7V at 8.8A peak pulse current (10/1000µs waveform). The device can dissipate up to 400W of peak pulse power and has a typical capacitance of 255pF at 1 MHz. It is a unidirectional or bidirectional type? The specs confirm bidirectional, as it has a bidirectional channel count of 1. The BZW04-28B is housed in a DO-204AC (DO-15) axial lead through-hole package, making it suitable for manual or automated assembly. Applications include transient protection for DC power lines, I/O interfaces, and sensitive ICs. The device is recognized by UL (per datasheet extract). Compliance data is available but unverified: RoHS3 compliant, REACH unaffected, and MSL level 1 unlimited.
