Current-driven control junction.
Use the example’s 330 Ω base resistor and 10 kΩ base-emitter return.
The buffered 5 V driver must source approximately 12.7 mA; do not assume every GPIO can do so.
Load terminal, also connected to the metal tab.
Connect the 100 Ω resistor load to this terminal.
The exposed tab is electrically live; insulate it when required.
Current return and base-drive reference.
Connect emitter to common driver and load ground.
Front view: B1, C2, E3; tab is collector.
