SBR8040

The SBR8040 is designed as one kind of 80 amp schottky rectifiers with working peak reverse voltage of 40V and repetitive peak reverse voltage of 40V.

SBR8040 has six features. (1)Schottky barrier rectifier. (2)175°C junction temperature. (3)Guard junction temperature. (4)Guard ring protection. (5)Reverse energy tested. (6)Vrrm, 40 to 50V. (7)80 amperes. Those are all the main features.

Some electrical characteristics of SBR8040 have been concluded into several points as follow. (1)Its average forward current would be 80 amps with test conditions of Tc=130°C and square wave and RJC=0.8°C/W. (2)Its maximum surge current would be 1200 amps with test conditions of 8.3ms, half sine and Tj=175°C. (3)Its max repetitive peak reverse current would be 2 amps with test conditions of f=1KHz, 25°C and 1us square wave. (4)Its max forward voltage would be 0.58V with test conditions of Ifm=80A and Tj=175°C and it would be 0.74V with test conditions of Ifm=80A and Tj=25°C. (5)Its max peak reverse current would be 30mA with test conditions of Vrrm, Tj=125°C and it would be 2mA with test conditions of Vrrm, Tj=25°C. (6)Its typical junction capacitance would be 2300pF with test conditions of Vr=5.0V and Tj=25°C. It should be noted that about the max peak forward voltage the pulse test: pulse width would be 300 usec and duty cycle 2%.

Also some thermal and mechanical characteristics of SBR8040 are concluded as follow. (1)Its storage temperature range would be from -65°C to 175°C. (2)Its operating junction temperature range would be from -65°C to 175°C. (3)Its max thermal resistance would be 0.8°C/W junction to sink. (4)Its typical thermal resistance greased would be 0.5°C/W cose to sink. (5)Its mounting torque would be 25 to 30 inch pounds. (6)Its weight would be 0.54 ounce (15.3 grams) typical. And so on.
