## **Description** 

**Product status** ~~hs~~ STPSC6H065 **Product summary Symbol Value** ~~ee~~ **IF(AV)** 6 A **VRRM** 650 V **Tj(max.)** 175 °C **Product label** ~~hs~~ 

This 6 A, 650 V SiC diode is an ultrahigh performance power Schottky diode. It is manufactured using a silicon carbide substrate. The wide band gap material allows the design of a Schottky diode structure with a 650 V rating. Due to the Schottky construction, no recovery is shown at turn-off and ringing patterns are negligible. The minimal capacitive turn-off behavior is independent of temperature. 

This STPSC6H065 is especially suited for use in PFC applications. This ST SiC diode will boost the performance in hard switching conditions. Its high forward surge capability ensures a good robustness during transient phases.
