DTC144TKAT146 Description

Short technical summary and product information.

The DTC144TKAT146 is an NPN pre-biased transistor from ROHM Semiconductor. It features a built-in 47kΩ base resistor, which simplifies circuit design by reducing external component count. Key electrical specifications include a collector-emitter voltage (Vceo) of 50V, a collector current (Ic) of 100mA, and a power dissipation of 200mW. The DC current gain (hFE) is a minimum of 100 at 1mA, 5V, and the transition frequency is 250MHz. The saturation voltage is 300mV maximum at 500µA base current and 5mA collector current. The device is housed in a surface mount SMT3 package, equivalent to TO-236-3, SC-59, and SOT-23-3, suitable for automated assembly. It is listed as RoHS3 compliant and has an MSL rating of 1 (unlimited).
