The BZW04-20B is a high-performance Transient Voltage Suppressor (TVS) Diode manufactured by Diotec. This unidirectional diode is specifically designed to protect sensitive electronic equipment from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). With a power dissipation rating of 400W, it effectively clamps voltage spikes at 20V, safeguarding downstream components. Housed in a DO-15 package, the BZW04-20B is easy to install and integrate into existing circuits. Supreme Components International is an authorised distributor of Diotec, ensuring you receive genuine, high-quality components. This TVS diode is suitable for a wide range of applications, including telecommunications, industrial control systems, and consumer electronics, where reliable overvoltage protection is crucial.
