Product Details

2N3906 PNP Transistor - General-Purpose Switching & Amplification

The 2N3906 is a general-purpose PNP silicon transistor housed in a TO-92 package, commonly used for small-signal amplification and switching duties. It is the direct complementary counterpart of the popular 2N3904 NPN transistor, making the pair a standard choice for push-pull and complementary-symmetry circuit designs in hobbyist and educational electronics.

Functions & Applications

Complementary to 2N3904: Perfect pairing for push-pull output stages and complementary-symmetry designs.
Standard TO-92 Package: Through-hole, breadboard-friendly form factor that's easy to solder.
Decent Current Gain: Typical hFE around 100-300, suitable for signal amplification and driver stages.
Low-Power Switching: Handles collector currents up to 200mA, enough for small relays, LEDs and transistor logic.
Widely Available Equivalent: One of the most common PNP parts, easy to cross-reference and replace.

Frequently Asked Questions

Q: What is the complementary NPN part for the 2N3906?
A: The complementary NPN transistor is the 2N3904, which shares the same voltage and current ratings but with reversed polarity.

Q: Can the 2N3906 switch a small 12V relay or LED?
A: Yes, as long as the load current stays below 200mA (Ic) and the applied voltage is under 40V (Vceo). Use a flyback diode with inductive loads like relay coils.

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