The datasheet specifies no recovery time above 500 mA output current, which means in a continuous-current-mode boost or totem-pole PFC stage the diode contributes zero reverse-recovery loss — the dominant loss mechanism in ultrafast silicon diodes at high frequency. ## 175 °C junction, AEC-Q101, and RoHS compliance The maximum junction temperature is 175 °C, and the AEC-Q101 qualification covers the stress and lifetime requirements for automotive power-train and body-electronics environments. The ECOPACK®2 series designation indicates a lead-free, halogen-free moulding compound. ## TO-247-3 package — thermal and layout checklist The TO-247-3 package has a large copper tab for heat-sink mounting. The cathode is electrically connected to the tab, so the thermal pad must be isolated or the heat sink must float. The 1250 pF junction capacitance at 0 V, 1 MHz is a design input for snubber sizing in hard-switching stages.","metaTitle":"STPSC40065CWY SiC Schottky Diode, 650V 20A, TO-247-3","metaDescription":"STPSC40065CWY SiC Schottky diode, 650 V reverse, 20 A average rectified, zero reverse recovery time, AEC-Q101, TO-247-3.
