For a SiC Schottky, that recovery time is essentially the RC time constant of the junction capacitance — there is no stored minority-carrier charge to sweep out. In practice, the reverse-recovery current is near zero, which eliminates the turn-on loss spike in the MOSFET or IGBT that drives the diode. If you are replacing a silicon ultrafast recovery diode in an existing PFC design, expect the switching losses in the main switch to drop measurably, and the diode itself runs cooler because there is no reverse-recovery dissipation. This is a current-production Infineon CoolSiC™+ part, available through independent distribution.","metaTitle":"Infineon IDW20G120C5BFKSA1 SiC Schottky Diode, 1200V, 31A","metaDescription":"IDW20G120C5BFKSA1 CoolSiC™+ SiC Schottky diode, 1200V reverse voltage, 31A average rectified per diode, common cathode, TO-247-3.","metaKeywords":null},"attributes":{"series":"CoolSiC™+","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":[],"specifications":{"Speed":"Fast Recovery =< 500ns, > 200mA (Io)","Series":"CoolSiC™+","Package":"Tube","Technology":"SiC (Silicon Carbide) Schottky","Mounting Type":"Through Hole","Package / Case":"TO-247-3","lifecycle_stage":"eol_hot","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"PG-TO247-3","Current - Reverse Leakage @ Vr":"83 µA @ 1200 V","Voltage - DC Reverse (Vr) (Max)":"1200 V","Operating Temperature - Junction":"-55°C ~ 175°C","Voltage - Forward (Vf) (Max) @ If":"1.65 V @ 10 A","Current - Average Rectified (Io) (per Diode)":"31A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$13.01","priceTiers":[{"qty":1,"price":"$13.01000","currency":"USD"},{"qty":30,"price":"$10.53267","currency":"USD"},{"qty":120,"price":"$9.91317","currency":"USD"},{"qty":510,"price":"$8.98382","currency":"USD"},{"qty":1020,"price":"$8.24034","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/884025f1fe441ad07bd242210fa17076.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/IDW20G120C5BFKSA1/alternatives.json"},"ai":{"faq":[{"question":"Is IDW20G120C5BFKSA1 a common cathode diode?","answer":"Yes, the diode configuration is 1 Pair Common Cathode.
