Vishay BZT03C43TR Zener Diode

The BZT03 series comprises high reliability Zener diodes designed for voltage regulation and transient suppression in electronic circuits. Featuring a glass passivated junction and hermetically sealed package, these diodes offer fast clamping times in picoseconds, making them suitable for medium power applications. They operate in a broad voltage range from 6.2 to 300 V, with test currents from 2 to 100 mA. With high surge current handling capability up to 600 W, they ensure stable operation under transient conditions. The BZT03 series is RoHS compliant, UL94V-0 flammability rated, and ideal for voltage regulation, voltage reference, and surge protection circuits.
