Product Details

BC301 NPN Transistor - Medium-Power Switching in a Rugged TO-39 Case

The BC301 is an NPN transistor housed in a metal TO-39 can, rated for 60V and 1A collector current with 850mW power dissipation. It is a solid choice for driving relays, small motors and moderate loads where the metal package offers better heat dissipation and mechanical ruggedness than a plastic TO-92.

Functions & Applications

60V Collector-Emitter Rating: Comfortable margin for 12V/24V relay and motor driving circuits.
1A Collector Current: Handles moderate loads directly without needing a Darlington stage.
Metal TO-39 Package: Better heat dissipation and shielding than plastic through-hole packages.
850mW Power Dissipation: Suitable for continuous medium-load switching with adequate cooling.

Frequently Asked Questions

Q: Can the BC301 directly drive a 12V automotive relay?
A: Yes, its 1A collector current and 60V rating comfortably handle typical 12V relay coils; use a flyback diode across the coil to protect the transistor.

Q: Is the BC301 still commonly used in new designs?
A: It is a legacy part mainly found in repair and restoration of older equipment; for new designs a modern TO-92/TO-126 equivalent with similar Vceo/Ic ratings is often easier to source.

Notes

This is a legacy metal-can transistor, mainly stocked for repair/restoration of vintage equipment rather than new designs.

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