Why the zero-recovery spec matters in a PFC or flyback stage
The STPSC8TH13TI is a silicon-carbide Schottky diode array with two 8 A, 650 V rated diodes in a series pair configuration — a topology choice for high-voltage boost or half-bridge legs where the zero reverse recovery time (0 ns trr) eliminates the turn-off loss tail that plagues silicon ultrafast diodes.
Headline ratings and what they drive
The 650 V reverse blocking voltage gives 1.5× derating headroom on a 400 V PFC bus, while the 80 µA leakage at 650 V and 175 °C junction rating means the part stays within its thermal budget in a cramped TO-220AB insulated package without an external heatsink for moderate loads.
Package and mounting — through-hole for power
The TO-220-3 through-hole package with an insulated tab lets you bolt the device directly to a grounded heatsink without an isolation pad.
