DTC123YKAT146 Description

Short technical summary and product information.

The DTC123YKAT146 is a pre-biased NPN bipolar transistor (digital transistor) from ROHM Semiconductor, designed for general-purpose switching and signal processing applications. The integrated 10kΩ base resistor simplifies circuit design by eliminating the need for an external resistor, reducing component count and PCB area. Key electrical characteristics include a maximum power dissipation of 200mW, a collector current rating of 100mA, and a collector-emitter voltage of 50V. The device offers a minimum DC current gain (hFE) of 33 at Ic=10mA and Vce=5V, with a maximum Vce saturation voltage of 300mV at Ib=500µA and Ic=10mA. The transition frequency is 250 MHz, making it suitable for low-frequency switching and amplification. The transistor is supplied in an SMT3 surface-mount package, which is compatible with the SOT-23-3 footprint. It is designed for surface-mount assembly and is RoHS3 compliant (unverified).
