DTA143EKAT146 Description

Short technical summary and product information.

The DTA143EKAT146 is a PNP pre-biased bipolar transistor manufactured by ROHM Semiconductor. It integrates a 4.7 kΩ base-emitter resistor, simplifying circuit design by reducing external component count. The transistor is rated for a collector-emitter voltage of 50V and a collector current of 100mA, with a power dissipation of 200mW.

 

With a DC current gain (hFE) of at least 30 at 10mA and 5V, and a transition frequency of 250MHz, this device is suitable for switching and amplification applications. The saturation voltage is 300mV at 500µA base current and 10mA collector current, ensuring efficient low-voltage operation.

 

The DTA143EKAT146 is housed in a TO-236-3 (SC-59, SOT-23-3) surface-mount package, specifically the SMT3 supplier device package. This compact package is ideal for space-constrained PCB designs and is compatible with standard surface-mount assembly processes.
