Zero-recovery switching — what it buys the power stage
The IDDD10G65C6XTMA1 is a silicon carbide Schottky diode from Infineon's CoolSiC+ generation. Its defining characteristic is zero reverse recovery time — the datasheet lists No Recovery Time > 500 mA (Io), which means the diode turns off with virtually no stored charge to sweep out. In a hard-switched PFC or inverter leg, that eliminates the reverse-recovery loss spike that plagues ultrafast silicon diodes, keeping the MOSFET or IGBT switch cooler and allowing higher switching frequencies without a thermal penalty.
650 V / 29 A — headroom for 400 VDC bus designs
Rated 650 V DC reverse and 29 A average rectified forward current, this diode comfortably covers the 400 VDC bus common in three-phase industrial drives, EV on-board chargers, and server PFC stages. The 650 V rating provides derating margin above the nominal bus voltage; the 29 A average current supports several kilowatts of output in a boost or bridgeless PFC topology. Junction temperature range extends from -55 °C to 175 °C, so the diode can sit in a hot enclosure or near a heatsink without forced air and still deliver its rated current.
PG-HDSOP-10-1 — surface-mount power package
Housed in a PG-HDSOP-10-1 module — Infineon's 10-lead surface-mount power package — the diode's large solderable pads carry the thermal path to the PCB copper plane. The package is a 10-PowerSOP module, surface-mount only, so the board layout must allocate enough copper area on the drain tab to keep junction temperature within the 175 °C limit at full load. No through-hole mounting; reflow profile follows standard lead-free solder (ROHS3 compliant).
Infineon lists this part with an Active product status. ROHS3 compliant, so it passes into EU and regional markets without an exemption expiry.
