STTH4L06
Turbo 2 ultrafast high voltage rectifier
■ Ultrafast switching
■ Low forward voltage drop
■ Low leakage current (platinum doping)
Description
The STTH4L06, which uses ST Turbo 2 600 V technology, is specially suited as boost diode in discontinuous or critical mode power factor corrections.
Packaged in DO-201AD and DO-15, this device is intended for use as a free wheeling diode in power supplies and other power switching applications.
