Product details

1200 V, 28 A fast recovery diode — what it means for the power stage

The Infineon IDP12E120XKSA1 is a fast-recovery silicon diode rated for 1200 V DC reverse voltage and 28 A average rectified current, housed in a TO-220-2 through-hole package (PG-TO220-2-2). The 150 ns reverse recovery time qualifies it for hard-switched topologies like PFC boost stages and secondary-side rectification in switch-mode power supplies. The forward voltage of 2.15 V at 12 A gives a realistic conduction-loss figure for thermal design. Junction temperature spans -55°C to 150°C.

Sourcing and lifecycle — active, no LTB pressure

ROHS3 compliant. For a BOM line that needs a 1200 V, 28 A fast recovery diode in a TO-220-2 package, this part is a straightforward fit with stable supply.

Frequently asked questions

What is the reverse recovery time (trr) of this diode?

The reverse recovery time is 150 ns, which qualifies it for fast-switching applications like PFC and SMPS output rectification.

What is the closest pin-compatible alternative to IDP12E120XKSA1?

No official cross-reference or second-source alternate appears in the available records. For a direct replacement, verify the 1200 V, 28 A, TO-220-2 footprint and 150 ns trr against any candidate part.
