The BZW04-188B is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Diotec. Supreme Components International is an authorised distributor of Diotec components, ensuring you receive genuine and high-quality products. This TVS diode is designed to protect sensitive electronic circuits from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). With a power dissipation rating of 400W, it effectively clamps overvoltage events at 188V. The BZW04-188B is housed in a DO-15 package, making it easy to integrate into existing designs. Its unidirectional configuration provides protection against positive voltage surges. This diode is suitable for a wide range of applications, including telecommunications, industrial equipment, and consumer electronics, where reliable overvoltage protection is crucial.
