Product Overview
The 1N5817 is a Vishay Schottky barrier rectifier for Power_Management use, configured as a single rectifier. Its voltage ratings include 20 V maximum repetitive peak reverse voltage, 14 V maximum RMS voltage, 20 V maximum DC blocking voltage, and 24 V maximum non-repetitive peak reverse voltage.
Forward-current capability is specified as 1.0 A maximum average forward rectified current with 0.375 in lead length at TL=90 °C. Surge capability is 25 A for an 8.3 ms single half sine-wave. Forward-voltage limits are 0.450 V at IF=1.0 A and 0.750 V at IF=3.1 A.
The DO-41 (DO-204AL) package uses matte tin plated leads solderable per J-STD-002, with a UL 94 V-0 molding compound and 275 °C maximum solder dip temperature.
