ULTRAFAST RECTIFIERS,
High Efficiency 25A and 30A
DESCRIPTION
The UES701(HR2) through UES703(HR2) series of ultrafast high-efficiency rectifiers is
specifically designed for operation in power switching circuits operating at frequencies of 20
kHz or higher. The low thermal resistance and forward voltage drop of this series allows the
user to replace larger DO-5 packaged devices in many applications. Microsemi also offers
numerous other products to meet higher and lower power voltage regulation applications.
High-Reliability
screening available

FEATURES
Very low forward voltage (0.825 V @ IF = 25 A).
Very fast recovery times (35-50 ns).
Low thermal resistance.
High reliability screening option.
Mechanically rugged.
Both polarities available.
RoHS compliant devices available by adding “e3” suffix (commercial grade only).
APPLICATIONS / BENEFITS
Power switching circuits 20 kHz and above with minimal parasitic switching losses.
Catch diodes for switching regulators.
Output rectifiers for high frequency square-wave inverters.
Extremely robust in power cycling.
High surge capability.
Hermetically sealed.
