DTC123EET1G Description

Short technical summary and product information.

The DTC123EET1G is an NPN pre-biased digital transistor (Bias Resistor Transistor) from ON Semiconductor. It integrates a series base resistor (R1=2.2kΩ) and a base-emitter resistor (R2=2.2kΩ) into a single device, eliminating external bias components. This simplifies circuit design and reduces board space. The transistor features a maximum collector-emitter voltage of 50V and a continuous collector current of 100mA. It offers a DC current gain (hFE) of minimum 8 at 5mA, 10V, and a low saturation voltage of 250mV at 5mA base current and 10mA collector current. The device is housed in a surface-mount SC-75 (SOT-416) package, suitable for automated assembly. It is RoHS compliant, Pb-Free, and Halogen Free. Typical applications include switching and amplification in low-power circuits where space is constrained.
