The DTA143XKAT146 is a PNP digital transistor from ROHM Semiconductor with built-in bias resistors, part of the DTA143X series. It integrates a 4.7kΩ input resistor (R1) and a 10kΩ resistor (R2) with a typical resistance ratio of 2.1, allowing an inverter circuit to be configured without external input resistors. Only the on/off conditions need to be set for operation, simplifying circuit design.
This device is rated for a maximum collector-emitter breakdown voltage of -50V and a maximum collector current of -100mA. Power dissipation is 200mW at 25°C ambient. DC current gain is minimum 30 at Ic=10mA and Vce=5V, with a maximum collector-emitter saturation voltage of 300mV at Ib=500µA and Ic=10mA. Input voltage on threshold is -2.5V minimum at Vo=0.3V and Io=20mA, and off threshold is -0.3V maximum at Vce=5V and Io=100µA. The transition frequency is 250 MHz typical.
The DTA143XKAT146 is supplied in a SOT-23-3 (SMT3) surface-mount package, also referred to as TO-236-3 or SC-59. It is suitable for inverter, interface, and driver applications. A complementary NPN type, the DTC143X series, is available for designs requiring both polarities. The part is provided on 8mm tape with 180mm reel, 3000 pieces per reel.
