This class of diode is used in power-supply output rectification, freewheeling diodes in motor drives, and snubber circuits where fast turn-off reduces switching losses. The 14-TSSOP footprint keeps the board layout compact, but at 31 A the PCB copper area must be sized for thermal spreading — the package alone won't sink that current without a decent pour. The 195 ns trr qualifies as fast recovery (under 500 ns at >200 mA). In a hard-switched converter, that recovery time sets the turn-off loss and the ringing amplitude.","metaTitle":"Infineon IDB18E120 Diode, 1.2 kV 31 A Fast Recovery","metaDescription":"Infineon IDB18E120 standard fast-recovery diode, 1200 V 31 A, 195 ns trr, 14-TSSOP.
