Ultrafast Recovery Diode

FMXA-1106S

November, 2005

D01-002EA-051128

■General Description

Shorter trr at high temperature has been realized by employing

the new life time control technology.

This is the optimum characteristic as a fast recovery diode

(FRD) for a continuous-current-mode PFC circuit.

■Package---TO220F-2Pin

■Applications

● PDP panel driver circuit.

● Continuous-current-mode PFC circuit.

● An output rectifier for SMPS, UPS, DC-DC converter.

● A Flywheel diode for the inverter and chopper.

■Features

● The shortest trr characteristic in the world at high

temperature (100°C).

Realized to shorten the trr at 100°C by 26% compared to

the conventional device.

(73ns => 54ns (typ), IF=IRP=500/500mA. Compared to

the SK’s conventional device FMX-G26S)
