Description
Product Details

BC231 PNP Transistor - Metal Can TO-39 for Signal & Switching

The BC231 is a PNP transistor housed in a rugged TO-39 metal can package, rated for 30V collector-emitter voltage and up to 0.35A of collector current. Its metal case offers better heat dissipation than plastic small-signal packages, making it a solid choice for older or repair-oriented analog designs that call for a PNP complement in a TO-39 footprint.

Functions & Applications

PNP Polarity: Complements NPN designs requiring a matching PNP device in TO-39.
Metal TO-39 Package: Better heat dissipation than plastic packages, useful in denser or repair applications.
30V Vceo Rating: Suitable for low-to-moderate voltage analog and switching stages.
0.35A Collector Current: Enough headroom for small relays, LEDs and signal-level loads.

Frequently Asked Questions

Q: Is the BC231 a direct replacement in TO-39 PNP circuits?
A: It's suitable in circuits designed around a 30V, 0.35A PNP TO-39 transistor; always check the exact pinout and gain (hFE) requirements of your specific design before substituting.

Q: Can the BC231 switch a small 12V relay?
A: Yes, provided the relay coil current stays below 0.35A. Use a flyback diode across the coil to protect the transistor from voltage spikes.

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