Its defining characteristic is zero reverse recovery time — trr is 0 ns, which means no charge-storage tail current when the diode commutates. In a continuous-conduction-mode PFC boost stage or a hard-switched inverter, that eliminates the reverse-recovery loss spike that costs efficiency and heats up the silicon FRED counterpart. ## Parametric profile for a 1–3 kW PFC or DC-DC stage Rated 650 V reverse with 20 A average forward current, the STPSC20065D covers the 1–3 kW PFC boost and DC-DC converter range where a single TO-220AC diode handles the boost or output rectifier slot. Forward voltage is 1.45 V maximum at 20 A and 25 °C junction — the on-state loss floor at full load. Junction temperature range is -40 to 175 °C, the standard SiC temperature grade that lets the diode share a heatsink with a 150 °C Tjmax MOSFET without being the thermal bottleneck. Capacitance is 1250 pF at 0 V bias, 1 MHz — this is the output capacitance the upstream switch sees during the voltage transition. In a 100 kHz PFC, the capacitive turn-on loss is negligible because the SiC Schottky has no stored charge; the 1250 pF figure is simply the junction capacitance that charges and discharges every cycle. Reverse leakage is 300 µA at 650 V and 25 °C — a low leakage floor that stays under 1 mA at 175 °C, which matters when the diode sits across a high-impedance bus in standby mode. ## Through-hole TO-220AC — thermal and assembly fit The TO-220AC package (TO-220-2 variant with the tab as the cathode) is a through-hole power package. The exposed metal tab is the back-side thermal pad — it must be soldered or clamped to a heatsink for any continuous load above a few amps. The 20 A rating assumes adequate heatsinking; in free air the thermal limit is well below 20 A. The through-hole leads fit a 0.100-inch pitch PCB pattern; no special soldering profile beyond standard leaded-wave or hand-solder. The ECOPACK®2 series designation means the part is RoHS-compliant and free of the restricted substances listed in the ST ECOPACK specification. ## Active lifecycle — no LTB window to manage ST lists the STPSC20065D product status as Active. The buyer can qualify this part into a production BOM without planning for a future LTB event.","metaTitle":"ST STPSC20065D SiC Schottky Diode, 650 V, 20 A, TO-220AC","metaDescription":"STMicroelectronics STPSC20065D silicon carbide Schottky diode: 650 V reverse voltage, 20 A average rectified current, zero reverse recovery (trr = 0 ns)","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Speed":"No Recovery Time > 500mA (Io)","Series":"ECOPACK®2","Package":"Tube","Diode Type":"Silicon Carbide Schottky","Mounting Type":"Through Hole","Package / Case":"TO-220-2","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STPSC20065","Capacitance @ Vr, F":"1250pF @ 0V, 1MHz","Supplier Device Package":"TO-220AC","Reverse Recovery Time (trr)":"0 ns","Current - Reverse Leakage @ Vr":"300 µA @ 650 V","Voltage - DC Reverse (Vr) (Max)":"650 V","Current - Average Rectified (Io)":"20A","Operating Temperature - Junction":"-40°C~175°C","Voltage - Forward (Vf) (Max) @ If":"1.45 V @ 20 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.4900","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d1c05f5acffa9deb82e2d20cd6149236.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the reverse recovery time (trr) of STPSC20065D?","answer":"The reverse recovery time is 0 ns — the silicon carbide Schottky structure has no minority-carrier stored charge, so there is no reverse recovery tail.
