1N5819-E3/54 Description

Short technical summary and product information.

The 1N5819-E3/54 is a Schottky barrier rectifier diode from Vishay General Semiconductor (part of Vishay Dale). It features a maximum reverse voltage (VRRM) of 40V and an average forward current (IF(AV)) of 1A. The diode has a low forward voltage drop of 0.6V at 1A, making it suitable for high-efficiency applications. It is designed for use in low voltage, high frequency inverters, freewheeling, DC/DC converters, and polarity protection circuits.

 

The device offers a peak forward surge current (IFSM) of 25A (8.3 ms single half sine-wave) and has a fast recovery time typical of Schottky diodes. It includes a guardring for overvoltage protection and operates over a junction temperature range of -65°C to 125°C.

 

The 1N5819-E3/54 is housed in a DO-204AL (DO-41) through-hole package with axial leads. It is RoHS-compliant (E3 suffix) and has a matte tin plated lead finish. The package has a flammability rating of UL 94 V-0.
