The HV variant of the D2PAK offers increased creepage distance for the 1200 V rating, which matters for high-voltage PCB layout where clearance and creepage must meet IEC/UL spacing requirements. ## Junction capacitance and switching behaviour The output capacitance measures 1650 pF at 0 V bias, 1 MHz. This capacitance charges and discharges each switching cycle, contributing to the switching loss in Coss-dominated topologies. The zero-recovery characteristic means the diode does not add a reverse-recovery charge component — the only capacitive loss is the output capacitance stored energy, which is predictable and frequency-dependent.","metaTitle":"STMicroelectronics STPSC20H12G2Y-TR SiC Schottky Diode","metaDescription":"STPSC20H12G2Y-TR: 1200 V, 20 A Silicon Carbide Schottky diode in D2PAK HV.
