A733 2SA733 PNP Transistor
2SA733 PNP bipolar transistor, 60V, 100 mA, TO-92
A PNP bipolar junction transistor rated at 60V collector-emitter and 100 mA collector current, used for small signal amplification and switching in audio and general purpose circuits. As a PNP device it conducts when its base is pulled low, which suits high side switching from a positive rail. Always fit a base resistor when driving it from a microcontroller pin - connecting a base directly to a logic output will damage both. A common starting value is 1K for switching applications. 60V and 100 mA rating suits moderate loads; TO-92 through-hole package fits breadboards; Very low cost and widely documented; Standard pinout for the 2SA733 family
