If you are looking for high current transistors in the range of 50 amps with a complementary pair, then you can try these Darlington transistors MJ11032 and MJ11033. The MJ11032 transistor is a Darlington NPN power transistor while the MJ11033 is its complementary PNP transistor which is also a Darlington power BJT.
Main features
The main features of the MJ11032 MJ11033 complementary Darlington pair transistors are as given below:
- High DC current gain of 1000 hFE minimum when the collector is operated at 25 amp DC
- DC current gain capacity may be reduced to 400 hFE, if the collector current rises to 50 amp DC
- The transistor is able to handle up to 100 amp if the current is in the pulsed manner
- Internal protection diode are provided to the transistors for protection against inductive transients.
- The monolithic design of the BJTs also include internal base/emitter shunt resistor to limit maximum base current.
- The 50 amp transistors are rated to handle junction temperatures as high 200 degrees Celsius
- Total power dissipation or power handling capacity without heatsink is 300 watts
