The BZW04-128 is a high-performance unidirectional TVS diode manufactured by Diotec and available from Supreme Components International, an authorised distributor of electronic components. This device is designed to protect sensitive electronic equipment from voltage transients. With a power dissipation rating of 400W and a reverse standoff voltage of 128V, the BZW04-128 effectively clamps transient voltages to safe levels, preventing damage to downstream components. Its unidirectional configuration makes it suitable for applications where protection against positive voltage surges is required. The DO-15 package ensures easy mounting and integration into various circuit designs. Applications include protection of I/O interfaces, VCC bus, and other vulnerable circuits in consumer electronics, industrial equipment, and telecommunications systems.
