Product details

The Infineon IDH15S120A is a 1.2 kV, 15 A silicon carbide Schottky diode in the CoolSiC™+ family, housed in a TO-220-2 through-hole package. Its zero reverse recovery time eliminates the switching losses that plague silicon fast-recovery diodes in hard-switched topologies like PFC boost stages, LLC converters, and motor-drive inverters. The 175 °C maximum junction temperature gives headroom for thermally demanding environments such as industrial power supplies, solar inverters, and EV charging infrastructure.

Zero reverse recovery time (0 ns trr) eliminates the turn-on loss spike in the driving MOSFET or IGBT.

The IDH15S120A is marked as Active in production — no end-of-life notice or last-time-buy risk on the horizon. For volume BOM planning, this part is a stable line item with no imminent replacement pressure.

Frequently asked questions

What is IDH15S120A used for?

It is a 1.2 kV, 15 A silicon carbide Schottky diode used in power-factor correction (PFC) stages, LLC resonant converters, motor-drive inverters, solar inverters, and EV charging power supplies where zero reverse recovery time and high junction temperature (175 °C) are required.

Is IDH15S120A a Schottky diode?

Yes, it is a silicon carbide Schottky diode, which gives it the zero reverse recovery time and high-voltage blocking capability that distinguish it from silicon pn-junction diodes.

Is IDH15S120A equivalent to C3D15060?

The C3D15060 is a 600 V, 15 A SiC Schottky from Cree/Wolfspeed, while the IDH15S120A is a 1.2 kV device — they are not direct equivalents because the voltage rating differs. For a 600 V application the C3D15060 is a functional alternative, but at 1.2 kV the IDH15S120A is the correct part.

What is IDH15S120A's listed speed?

The listed speed is 'No Recovery Time > 500mA (Io)', which means the diode exhibits zero reverse recovery time at forward currents above 500 mA — the key performance advantage of SiC Schottky technology.
