Transistor PNP A733

The A733 is a versatile PNP transistor in a TO-92 package, widely used for amplification and switching applications. It finds applications in commercial equipment, educational kits, toys, and DIY electronics projects. With a collector-emitter voltage of -50V and a maximum collector current of -150mA, the A733 is suitable for driving small loads. Its low saturation voltage (0.3V) and high current gain (up to 600) make it an efficient choice for both amplification and switching tasks.

Usage

The A733 can be used for general-purpose amplification and switching. When used as a switch, it can handle loads under 150mA, such as relays, LEDs, ICs, and small transistors. Its low base-emitter saturation voltage (0.3V) makes it suitable for low-voltage circuits. In amplification applications, it performs well in audio preamplifiers, signal amplification, and RF circuits up to 180MHz. It can also be used in Darlington pairs fo
