1N5819UR-1 Description

Short technical summary and product information.

The 1N5819UR-1 is a Schottky barrier rectifier manufactured by Microchip Technology. It features a low forward voltage drop of 490 mV at 1 A, a reverse voltage rating of 45 V, and an average rectified current of 1 A. The device offers fast recovery with a maximum recovery time of 500 ns at currents above 200 mA, making it suitable for high-speed switching applications.

 

This rectifier is housed in a hermetically sealed DO-213AB (MELF, LL41) glass package, designed for surface mount mounting. It operates over a wide temperature range from -65°C to 150°C. The junction capacitance is typically 70 pF at 5 V and 1 MHz.

 

Per the datasheet, these devices are available with military-grade qualifications (JAN, JANTX, JANTXV, JANS) and RoHS compliant versions are available for commercial applications. The hermetic seal provides high reliability in harsh environments.
