MJE350 PNP Bipolar Power Transistor (TO-126)

The MJE350 is the PNP half of the MJE340/MJE350 high-voltage complementary pair, matched in voltage and current rating so a design that needs both polarities at this elevated 300V range has both parts available. This pairing shows up in complementary high-voltage switching stages and specialized power supply topologies where a standard-voltage complementary pair like the BC547/BC557 simply isn't rated high enough to survive the circuit's actual operating voltage.
