The MJE340 and MJE350 are complementary silicon power transistors preferred by STMicroelectronics.
The MJE340 is a NPN transistor for medium power linear and switching applications, while the MJE350 is the complementary PNP type.
The transistors have absolute maximum ratings for collector-emitter voltage, emitter-base voltage, collector current, and total power dissipation.
They also have thermal resistance and electrical characteristics specified.
The transistors are mounted in SOT-32 and are intended for use in linear and switching industrial equipment.
