High Voltage Transistor MJ11021(PNP) MJ11022 (NPN) Datasheet - Complimentary Pair

MJ11021(PNP) MJ11022 (NPN) are high voltage complimentary pair Darlington transistors suitable for all applications that involve high voltage high current such as in motor control, inverters, etc.

Let's understand the datasheet and the main specifications of the devices:

Main Electrical Features



  1. MJ11021(PNP) MJ11022 (NPN) are 250V, 15 amp complimentary Darlington transistors

  2. Being Darlington by nature, the devices exhibit a high Dc current gain, typically at 10amp, the hFe could be at least 400

  3. The collector to emitter continuously voltage handling capacity is minimum 250V

  4. Low saturating voltage requirement for collector emitter, at around 1V when current is @ 5amps.

  5. The devices are SOA verified @ 44V VCE and 4 amp current for 250ms

  6. These are manufactured without any Pb content.
