The DTA143TKAT146 is a PNP pre-biased digital transistor from ROHM Semiconductor, part of the DTA143T series. It integrates a 4.7 kΩ bias resistor (R1) directly into the transistor, enabling inverter circuit configurations without external input resistors. This simplifies PCB design and reduces component count.
Key electrical ratings include a maximum collector-emitter voltage (VCEO) of -50V, a maximum collector current (IC) of -100mA, and a power dissipation of 200mW. The device offers a DC current gain (hFE) range of 100 to 600 at Ic = -1mA and Vce = -5V, with a typical gain of 250. The transition frequency (fT) is 250 MHz, making it suitable for switching applications.
The transistor is housed in a surface-mount SMT3 package (TO-236-3 / SC-59 / SOT-23-3) and is supplied on 180mm reels with 8mm tape width, with a basic ordering quantity of 3000 pieces. The operating junction temperature range is -55°C to +150°C.
