Product Details

BCX38B - Higher Current NPN Switching Transistor in TO-92

The BCX38B is an NPN transistor in a TO-92 package, rated for 60V collector-emitter voltage and up to 800mA of collector current, making it a good step up from general-purpose small-signal transistors for slightly heavier switching loads. It suits relay driving, low-power motor control and general switching tasks in DIY and educational projects.

Functions & Applications

Higher Current Handling: Supports up to 800mA, useful where BC547-class transistors fall short.
60V Rating: Good voltage margin for driving relays, solenoids and small inductive loads.
Standard TO-92 Package: Through-hole, easy to solder and breadboard-friendly.
General-Purpose Switching: Suitable for low-power motor and relay driver stages.

Frequently Asked Questions

Q: Can the BCX38B replace a BC547 in higher-current circuits?
A: Yes, the BCX38B handles up to 800mA versus 100mA for the BC547, making it a good choice when the load current exceeds what small-signal transistors can safely switch.

Q: Is the BCX38B suitable for driving a 12V relay?
A: Yes, as long as the relay coil current stays within 800mA and a flyback diode is used to protect against inductive voltage spikes.

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