Product Details

BC211 NPN Transistor - Rugged TO-39 Metal Case, 1A Rated

The BC211 is an NPN bipolar junction transistor housed in a TO-39 metal can package, rated for 40V collector-emitter voltage and up to 1A of collector current, making it a solid choice for general-purpose amplification and switching tasks that benefit from a robust metal enclosure.

Functions & Applications

1A Collector Current: Handles moderate-load switching and amplification tasks with margin.
40V Vceo Rating: Suitable for circuits operating well above standard 5V/12V logic rails.
Metal TO-39 Package: Offers better heat dissipation and mechanical durability than plastic TO-92 parts.
General-Purpose Design: Works well in both linear amplification and switching circuit designs.

Frequently Asked Questions

Q: Can the BC211 handle a 24V supply rail?
A: Yes, its 40V Vceo rating gives comfortable headroom for circuits running on 12V or 24V supplies, as long as collector current stays within 1A.

Q: Why choose the BC211 over a plastic TO-92 transistor?
A: The TO-39 metal can package dissipates heat more effectively and offers greater mechanical robustness, useful in designs with higher current or where the transistor is subject to physical stress.

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