2SA1015 PNP Transistor - The Classic Partner to 2SC1815

The 2SA1015 is a widely used PNP silicon transistor, best known as the complementary counterpart to the NPN 2SC1815 in countless audio and general-purpose circuits. Its low noise figure and good hFE linearity make it a favorite for driver-stage amplifiers, Class B push-pull audio output stages, and small-signal switching in hobbyist and repair work.

Functions & Applications

Complementary Pair: Designed to work together with the NPN 2SC1815 in symmetrical push-pull audio stages.
Low Noise: Suited for driver-stage and low-frequency amplifier applications where signal clarity matters.
Standard TO-92 Package: Through-hole design, easy to solder on breadboards and prototyping boards.
Good hFE Linearity: Stable current gain across a range of collector currents, useful for linear amplification.
Wide Availability of Gain Groups: Sold in O, Y, GR and L grades so builders can match hFE to circuit needs.

Frequently Asked Questions

Q: What is the complementary NPN transistor for the 2SA1015?
A: The 2SC1815 is the standard complementary NPN pair to the 2SA1015, sharing similar voltage, current and gain ratings for Class B push-pull audio circuits.

Q: How much current can the 2SA1015 switch?
A: The 2SA1015 is rated for a maximum collector current of 150mA and a Vceo of 50V, so it is best suited for small-signal switching and driver stages rather than high-current loads.
