Additional Details

The DTD723YE has a collector-emitter voltage (VCEO) of -50V and a collector current (IC) of -100mA. The power dissipation is typically around 200mW. The input resistor (R1) is 2.2 kΩ, and the resistor between base and supply voltage (R2) is 47 kΩ. The transistor is housed in a surface-mount SOT-346 package. It's designed for use in a wide range of applications where a pre-biased PNP transistor is needed for switching or amplification. The integrated resistors eliminate the need for external bias resistors, saving space and reducing component count. The device is RoHS compliant, meaning it is lead-free and environmentally friendly.
