Transistor PNP A1015

The A1015 is a low-cost, high-quality PNP transistor primarily designed for audio amplification and related stages. With a maximum collector-emitter voltage of 50V, it is well-suited for circuits operating under 40V DC for optimal performance. The transistor supports a maximum collector dissipation of 400mW and offers a DC gain of up to 400, making it ideal for small audio amplification tasks. Additionally, the A1015 can be used as a switch, capable of handling loads up to 150mA.

Usage

The A1015 is designed mainly for audio applications. It can function as a small audio amplifier in devices like doorbells, MP3 players, radios, and other low-power audio systems. It is also useful in amplifier stages within larger audio circuits. As a switch, it can drive LEDs, relays, ICs, and higher power transistors under the 150mA load limit.

Applications

  • Audio preamplifier circuits
  • Audio amplifier circuits
  • Audio amplification stages
  • Switching loads under 150mA

Safe Operating Guidelines

To ensure reliable and long-term operation:

  • Do not exceed -50V on the collector-emitter voltage (preferably keep under 40V for stable use).
  • Keep the load current below 150mA.
  • Always use a suitable base resistor to limit base current.
  • Maintain operating temperatures under 125°C.
  • Store the transistor between -65°C and +150°C.
