BZW04-376B Description

Short technical summary and product information.

The BZW04-376B is a bidirectional Transil TVS diode from STMicroelectronics designed to protect sensitive electronics from voltage transients. It features a stand-off voltage of 376V and a minimum breakdown voltage of 418V, clamping transient overvoltages to a maximum of 603V at 800mA peak pulse current (10/1000µs waveform). With a peak pulse power dissipation of 400W, this diode provides robust protection for general-purpose applications.

 

Key electrical characteristics include a low leakage current of 1µA at the stand-off voltage, a forward voltage drop of 1.5V, and a capacitance of 35pF at 1MHz. The device operates over a wide temperature range from -65°C to +175°C, with junction-to-lead thermal resistance of 60°C/W and junction-to-ambient thermal resistance of 100°C/W.

 

The BZW04-376B is housed in a DO-204AC (DO-15) axial leaded package, suitable for through-hole mounting. It is not intended for power line protection but is ideal for protecting voltage-sensitive components in industrial, telecom, and consumer electronics.
