Additional Details

The DTA124ES contains a PNP transistor with integrated resistors. The input resistor (R1) is 10 kΩ, and the resistor between the base and the power supply (R2) is also 10 kΩ. The output current is typically 100mA, and the collector-emitter voltage rating is generally around 50V. It comes in a standard SOT-23 package. The integrated resistors ensure stable operation and reduce the effects of temperature variations. This part is now listed as End-of-Life by the manufacturer.
