MJ11021(PNP) MJ11022 (NPN) are high voltage complementary pair Darlington transistors suitable for all applications that involve high voltage high current such as in motor control, inverters, etc.
So I have explained the datasheet and the main specifications of the devices:
Main Electrical Features
- MJ11021(PNP) MJ11022 (NPN) are 250V, 15 amp complementary Darlington transistors
- Being Darlington by nature, the devices exhibit a high Dc current gain, typically at 10amp, the hFe could be at least 400
- The collector to emitter continuously voltage handling capacity is minimum 250V
- Low saturating voltage requirement for collector emitter, at around 1V when current is @ 5amps.
- The devices are SOA verified @ 44V VCE and 4 amp current for 250ms
- These are manufactured without any Pb content.
