STPS8L30
Low drop power Schottky rectifier
Main product characteristics
Features and benefits
■ Low cost device with low drop forward voltage
for less power dissipation and reduced
heatsink
■ Optimized conduction/reverse losses trade-off
which leads to the highest yield in the
application
■ High power surface mount miniature package
■ Avalanche capability specified
Description
Single Schottky rectifier suited to Switched Mode
Power Supplies and high frequency DC to DC
converters.
Packaged in DPAK and IPAK, this device is
especially intended for use as a Rectifier at the
secondary of 3.3 V SMPS or DC/DC units.
