DTB113ZKT146 Description

Short technical summary and product information.

The DTB113ZKT146 is a PNP pre-biased transistor manufactured by ROHM Semiconductor. It is designed for surface mount applications in a compact SOT-23-3 package (TO-236-3, SC-59, SOT-23-3) with an SMT3 supplier device package.

 

Electrical characteristics include a collector-emitter voltage (Vceo) of 50V and a collector current rating of 500mA. Power dissipation is rated at 200mW. The transistor integrates a base resistor of 10 kΩ, providing built-in biasing for simplified circuit design. DC current gain (hFE) is minimum 56 at 50mA, 5V, and Vce saturation is maximum 300mV at Ib=2.5mA, Ic=50mA. Transition frequency is 200 MHz.

 

The device is listed as RoHS3 compliant and has an MSL of 1 (unlimited). It is suitable for low-power switching and amplification in space-constrained designs.
