It is manufactured using a silicon carbide substrate. The wide band-gap material allows the design of a low VF Schottky diode structure with a 1200 V rating. **Product status link** STPSC20H12CWY |**Product summary**|**Product summary**| |---|---| |**IF(AV)**|2 x 10 A| |**VRRM**|1200 V| |**Tj (max.)**|175 °C| |**VF (typ.)**|1.35 V| ||| |**Product label**|| 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. Especially suited for use in PFC and secondary side applications, this ST SiC diode will boost the performance in hard switching conditions. This rectifier will enhance the performance of the targeted application. Its high forward surge capability ensures a good robustness during transient phases. **DS12793** - **Rev 1** - **November 2018** For further information contact your local STMicroelectronics sales office. www.st.com **STPSC20H12CWY Characteristics** **1** ## **Characteristics** **Table 1.
