Additional Details

The DTC123ES comes in a small surface-mount package, making it suitable for high-density circuit boards. The built-in bias resistors eliminate the need for external resistors, further reducing board space and component count. The specific resistor values (R1 = 2.2 kΩ, R2 = 10 kΩ) provide a defined input impedance and base current, simplifying the design process. The absolute maximum ratings include a collector-emitter voltage of 50V, a collector current of 100mA, and a total power dissipation of 200mW. It's crucial to consult the datasheet for precise electrical characteristics and recommended operating conditions. This transistor is commonly available in SOT-23 package.
