S20LC40

The S20LC40 is designed as one kind of super fast recovery rectifiers with voltage of 400V and current of 20A. Its typical applications include switching power supply, free wheel and home appliances, office equipment and factory automation.

S20LC40 has three features. (1)It has low noise. (2)Its trr would be 50ns. (3)It has small jc. Those are all the main features.

Some absolute maximum ratings of S20LC40 have been concluded into several points as follow. (1)Its storage temperature range would be from -40°C to 150°C. (2)Its operating junction temperature would be 150°C. (3)Its maximum reverse voltage would be 400V. (4)Its average rectified forward current would be 20A with conditions of 50Hz sine wave and R-load and rating for each diode Io/2 and Tc=119°C. (5)Its peak surge forward current would be 120A with conditions of 50Hz sine wave and non-repetitive 1 cycle peak value and Tj=25°C. (6)Its mounting torque would be 0.8Nm and its recommended value is 0.5Nm. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of S20LC40 are concluded as follow. (1)Its forward voltage with symbol of Vf would have the maximum value of 1.3V with conditions of If=20A and pulse measurement and rating of per diode. (2)Its reverse current with symbol of Ir would have the maximum value of 10uA with conditions of Vr=Vrm and pulse measurement and rating of per diode. (3)Its reverse recovery time would have the maximum value of 50ns with conditions of If=0.5A and Ir=1A and rating of per diode. (4)Its thermal resistance would have the maximum value of 1.2°C/W with conditions of junction to case. And so on. At present we have not got so much information about this IC and we would try hard to get more information about it.
