U1DL44A

The U1DL44A is a kind of high efficiency rectifier (HED). It is silicon epitaxial junction type. The U1DL44A device is intended for switching type power supply applications. There are some features of U1DL44A as follows: (1)average forward current: IF(AV)=1.0 A; (2)repetitive peak reverse voltage: VRRM=200 V; (3)very fast reverse-recovery time: trr=35 ns max; (4)low forward voltage, VFM: 0.98 V; (5)available to reduce switching losses and output noise; (6)surface mounting plastic mold package.

The following is about the maximum ratings of U1DL44A: (1)repetitive peak reverse voltage, VRRM: 200 V; (2)average forward current, IF(AV): 1.0 A; (3)peak one cycle surge forward current (non-repetitive), IFSM: 10 A (50 Hz) and 11 A (60 Hz); (4)junction temperature, Tj: -40 to 150; (5)storage temperature range, Tstg: -40 to 150.

The last one is about the electrica characteristics (Ta=25) of U1DL44A: (1)peak forward voltage, VFM: 0.98 V max at IFM=1.0 A; (2)repetitive peak reverse current, IRRM: 10A max at VRRM=200 V; (3)reverse recovery time, trr: 35 ns max at IF=1 A, di/dt=-30 A/s; (4)forward recovery time, tfr: 100 ns max at IF=1 A.
