Main product characteristics
Features and benefits
Description
Single Schottky rectifier suited to switched mode
power supplies and high frequency DC to DC
converters.
Packaged in SMB, SMB flat for thermal resistance
characteristic improvement, this device is
especially intended for use in parallel with
MOSFETs in synchronous rectification.
