The DTA123EKAT146 is a PNP pre-biased digital transistor (bias resistor built-in transistor) from ROHM Semiconductor, part of the DTA123E series. It integrates two bias resistors R1 and R2, each 2.2 kΩ, eliminating the need for external resistors in inverter circuits. The device is rated for a maximum collector-emitter voltage of -50V, maximum collector current of -100mA, and a power dissipation of 200mW. DC current gain (hFE) is minimum 20 at 20mA collector current and 5V collector-emitter voltage, with a typical transition frequency of 250MHz. Vce saturation is typically 100mV at 500µA base current. The transistor is housed in a SOT-346 (SMT3) surface mount package, which is compact and suitable for automated assembly. It is supplied in tape and reel packaging with 3000 pieces per reel (180mm reel, 8mm tape width). The complementary NPN type is the DTC123E series. Typical applications include inverter, interface, and driver circuits.
