Vishay 800 V 1 A Surface Mount Avalanche Diode SMF (DO-219AB) AU1FK-M3/H

Vishay AU1FK-M3/H avalanche diode is a high-reliability 2-pin diode supplied in a compact SMF (DO-219AB) surface mount package designed to meet rigorous industrial requirements. With a maximum continuous forward current of 1 A and a peak reverse repetitive voltage rating of 800 V, it provides robust protection and rectification in electronic circuits.

The device's low forward voltage drop of 1.85 V and fast reverse recovery time of 75 ns reduce power loss and switching time, enhancing system efficiency. The glass passivated pellet chip junction and the low profile package allow seamless integration into automated assembly lines.

This avalanche diode is ideal for a wide range of industrial, automotive, consumer, and telecommunication applications, including power supply rectification, inverter circuits, freewheeling diodes, and voltage surge protection.

The diode withstands operating temperatures from -55°C to 175°C and can handle peak surge currents up to 25 A, making it suitable for demanding environments. The diode supports a maximum continuous forward current of 1 A.

It has a peak reverse repetitive voltage rating of 800 V. The diode features a low profile SMF (DO-219AB) package for automated placement. Low forward voltage drop of 1.85 V and low reverse current improve efficiency. Operational temperature range from -55°C up to 175°C ensures durability.

Peak non-repetitive forward surge current capacity is 25 A. Peak reverse recovery time is fast at 75 nanoseconds. Glass passivated pellet chip junction enhances reliability. RoHS compliant and suitable for consumer, automotive, and telecommunication industries.
