Frequently Asked Questions

Q: What is the complementary NPN partner for BC328?
A: The complementary NPN transistor is the BC337. Together they form a matched pair ideal for push-pull output stages and balanced amplifier circuits.

Q: Can BC328 drive an LED directly from a microcontroller?
A: Yes. With a suitable current-limiting base resistor (~1kΩ for 5V logic), the BC328 can switch an LED or small load up to 50mA from any 3.3V or 5V microcontroller output.

Note: Price refers to one (1) piece. The component is shipped in bulk without individual packaging.
