The BZW04-37B is a high-performance, unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Diotec. As an authorised distributor, Supreme Components International guarantees the authenticity and quality of this component. This diode is specifically designed to protect sensitive electronic circuits from voltage transients induced by lightning, electrostatic discharge (ESD), and inductive load switching. Featuring a power dissipation of 400W and a minimum breakdown voltage (Vbr) of 37.6V, the BZW04-37B effectively clamps overvoltage events, preventing damage to downstream components. Its unidirectional configuration makes it suitable for applications where protection is required in one direction only. The DO-15 package provides easy mounting and integration into various circuit designs. Ideal for use in telecommunications equipment, industrial control systems, and consumer electronics.
