The DTC123YUAT106 is an NPN digital transistor (pre-biased) from ROHM Semiconductor's DTC123Y series. It integrates two bias resistors (R1=2.2kΩ, R2=10kΩ) directly into the device, eliminating the need for external input resistors and simplifying inverter circuit design. The transistor is rated for a collector-emitter voltage of 50V and a continuous collector current of 100mA, with a maximum power dissipation of 200mW when mounted in the UMT3 package.
Electrical performance includes a minimum DC current gain of 33 at Ic=10mA and Vce=5V, a typical transition frequency of 250MHz, and a low Vce saturation voltage of 300mV maximum at Ib=500µA, Ic=10mA. The device operates over a junction temperature range up to 150°C and is stored between -55°C and +150°C.
The transistor is supplied in a surface-mount SC-70 (SOT-323) package, also designated as UMT3 by ROHM. It is tape-and-reel packaged with 3000 pieces per reel on 8mm tape and 180mm reel, suitable for automated assembly. Typical applications include inverter circuits, interface circuits, and driver stages where built-in bias simplifies design and reduces component count.
