DTC143ZKAT146 Description

Short technical summary and product information.

The DTC143ZKAT146 is an NPN pre-biased bipolar junction transistor manufactured by ROHM Semiconductor. It integrates a 47kΩ base resistor, simplifying circuit design by reducing external component count. The device is rated for a collector-emitter voltage of 50V and a continuous collector current of 100mA, with a power dissipation of 200mW.

 

Electrical characteristics include a minimum DC current gain (hFE) of 80 at 10mA collector current and 5V collector-emitter voltage. The maximum Vce saturation voltage is 300mV at a base current of 250µA and collector current of 5mA. The transition frequency is 250 MHz, making it suitable for switching and amplification applications up to moderate frequencies.

 

The transistor is housed in a surface mount SMT3 package, which is compatible with TO-236-3, SC-59, and SOT-23-3 footprints. This compact package enables high-density PCB designs and automated assembly processes.
