Product details

Fast recovery rectifier for 1.2 kV bus rails

The Infineon IDP09E120XKSA1 is a standard fast recovery diode rated for 1200 V DC reverse voltage and 23 A average rectified current. It comes in a through-hole TO-220-2 package (PG-TO220-2-1). Its 140 ns reverse recovery time places it inside the fast-recovery class (trr ≤ 500 ns), making it a candidate for hard-switched PFC boost stages, flyback secondary rectification, and DC-link freewheeling in motor drives or UPS inverters where recovery losses at turn-off matter.

Forward drop and switching loss trade-off

Forward voltage is 2.15 V at 9 A. The 140 ns trr reduces reverse-recovery charge compared to a 500 ns part.

Leakage and temperature range

Reverse leakage is 100 µA at 1200 V. Junction temperature spans -55°C to 150°C.

Active lifecycle, no obsolescence concern

The IDP09E120XKSA1 carries an active product status. No NRND or last-time-buy notice is on record. It is ROHS3 compliant.

Frequently asked questions
