What the zero reverse recovery time means for the switching stage
The Infineon IDDD12G65C6XTMA1 is a CoolSiC™+ Silicon Carbide Schottky diode rated for 650 V reverse voltage and 34 A average rectified current. Its defining spec is a reverse recovery time (trr) of 0 ns — meaning there is no stored charge to sweep out when the diode commutates. In a hard-switched PFC boost or inverter leg, that eliminates the reverse-recovery loss spike that a silicon ultrafast diode would generate, which directly reduces the switching loss in the companion MOSFET or IGBT and lowers the overall junction temperature in the power stage.
Package and mounting — what fits the board
The part is supplied in a 10-PowerSOP Module (PG-HDSOP-10-1), a surface-mount package designed for automated assembly. The junction temperature range of -55 °C to 175 °C covers both cold-start and sustained high-load conditions typical of industrial power supplies and automotive on-board chargers. The 594 pF capacitance at 1 V, 1 MHz is the small-signal value; in a switching application the effective output capacitance is lower under reverse bias, so the driver sees a manageable capacitive turn-on current.
Lifecycle and sourcing posture
Infineon lists the IDDD12G65C6XTMA1 as an active product with ROHS3 compliance. No end-of-life notice or last-time-buy window is in effect, so it can be specified into new designs and qualified for production without near-term obsolescence risk.
