DTB143TKT146 Description

Short technical summary and product information.

The DTB143TKT146 is a PNP pre-biased bipolar junction transistor manufactured by ROHM Semiconductor. It integrates a base resistor (R1 = 4.7 kΩ) to simplify circuit design by reducing external component count. The transistor is rated for a maximum collector-emitter breakdown voltage of 40 V and a maximum collector current of 500 mA, with a power dissipation of 200 mW.

 

Key electrical characteristics include a minimum DC current gain (hFE) of 100 at Ic=50 mA and Vce=5 V, and a typical transition frequency of 200 MHz. The saturation voltage is 300 mV maximum at Ib=2.5 mA and Ic=50 mA.

 

The device is housed in a TO-236-3 / SC-59 / SOT-23-3 surface-mount package, with the supplier device package designated as SMT3. It is designed for surface-mount assembly and is suitable for general-purpose switching and amplification applications where space is limited.
