Additional Details

The DTA124TM features a PNP transistor with an integrated resistor network. The input resistor (R1) is typically around 10kΩ, and the base-emitter resistor (R2) is also around 10kΩ. It's designed for low to medium current applications. Typical collector current (Ic) is in the range of 100mA, and the collector-emitter voltage (Vce) is usually around 50V. The part is supplied in a surface-mount package. Rohm Semiconductor now lists this component as End-of-Life.
