For a 31 A, 1200 V boost PFC or inverter freewheel leg, this trr sets the turn-off switching loss and dictates the minimum snubber capacitance needed to keep the peak reverse-recovery current within the IGBT or MOSFET SOA. Forward voltage is 2.15 V typical at 18 A — a reasonable conduction-loss trade-off for the fast recovery characteristic. Reverse leakage is 100 µA at the full 1200 V blocking voltage, which matters for high-temperature off-state losses.","metaTitle":"Infineon IDP18E120XKSA1 Fast Recovery Diode","metaDescription":"Infineon IDP18E120XKSA1 standard fast recovery diode, 1200V 31A, trr 195 ns, TO-220-2.
