**TO-247 STTH30R03CW** 

## **FEATURES AND BENEFITS** 

- I Designed for high frequency applications. 

- I Hyperfast recovery competes with GaAs devices. 

- I Allows size decrease of snubbers and heatsinks. 

## **DESCRIPTION** 

The TURBOSWITCH "R" is an ultra high performance diode. 

This TURBOSWITCH family, which drastically cuts losses in associated MOSFET when run at high dIF/dt, is suited for HF OFF-Line SMPS and DC/DC converters.
