ON MBRS540T3 Surface mount schottky power rectifier Datasheet

MBRS540T3
Preferred Device
Surface Mount Schottky
Power Rectifier
The MBRS540T3 employs the Schottky Barrier principle in a large
area metal−to−silicon power diode. State−of−the−art geometry
features epitaxial construction with oxide passivation and metal
overlay contact. Ideally suited for low voltage, high frequency
rectification, or as free wheeling and polarity protection diodes in
surface mount applications where compact size and weight are critical
to the system.

Preferred devices are recommended choices for future use
and best overall value.
Maximum ratings are those values beyond which device damage can occur.
Maximum ratings applied to the device are individual stress limit values (not
normal operating conditions) and are not valid simultaneously. If these limits are
exceeded, device functional operation is not implied, damage may occur and
reliability may be affected.
1. The heat generated must be less than the thermal conductivity from
Junction−to−Ambient: dPD/dTJ < 1/RqJA.
