STTH1R04
Ultrafast recovery diode
Features
■ Negligible switching losses
■ Low forward and reverse recovery times
■ High junction temperature
Description
The STTH1R04 series uses ST's new 400 V
planar Pt doping technology. The STTH1R04 is
specially suited for switching mode base drive and
transistor circuits.
Packaged in axial and surface mount packages,
this device is intended for use in low voltage, high
frequency inverters, free wheeling and polarity
protection.
