Can I drive a relay or high-current load directly from an Arduino pin with MJE13005A?
Not directly. Arduino pins supply only a few tens of milliamps, while this transistor needs a meaningful base current to switch its collector current. Use a base resistor and a sufficient base drive, or choose a logic-level MOSFET for direct microcontroller control. Add a flyback diode across any inductive load such as a relay coil.
Is MJE13005A suitable for switch-mode power supply designs on mains voltage?
Its 400V collector-emitter rating makes it a common choice for switching stages in SMPS and ballast circuits. Mains designs need proper isolation, snubber networks, heatsinking and adherence to the manufacturer's safe operating area, so consult the datasheet before using it in a mains-connected circuit.
