SB540 Description

Short technical summary and product information.

The Vishay Dale SB540 is a Schottky Barrier Rectifier designed for low voltage, high frequency applications such as inverters, freewheeling circuits, and DC-to-DC converters. It features a guardring for overvoltage protection, extremely fast switching speeds, and a high forward surge capability.

Key electrical characteristics include a maximum repetitive peak reverse voltage of 20V, a maximum average forward rectified current of 5A, and a peak forward surge current of 220A. The maximum instantaneous forward voltage is 0.48V at 5A. The operating junction temperature range is -65°C to +150°C.

This rectifier is housed in a DO-201AD case with matte tin plated leads, suitable for through-hole mounting. The molding compound meets UL 94 V-0 flammability rating. It is compliant to RoHS directive 2002/95/EC and WEEE 2002/96/EC.
