The BZW04-85B is a high-performance, unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Diotec. This diode is designed to protect sensitive electronic circuits from voltage transients induced by lightning, electrostatic discharge (ESD), and inductive load switching. With a power dissipation rating of 400W and a breakdown voltage (Vbr) of 85V, the BZW04-85B effectively clamps overvoltage events, preventing damage to downstream components. Its unidirectional configuration allows it to suppress positive voltage transients. Housed in a DO-15 package, it is easy to install and integrate into various circuit designs. Supreme Components International is an authorised distributor of Diotec components, ensuring you receive genuine and reliable products. Trust the BZW04-85B for robust circuit protection in your applications.
