The DTA143EKA is a PNP digital transistor with built-in bias resistors R1 and R2, both rated at 4.7 kΩ, designed for inverter, interface, and driver applications. It is packaged in SOT-346 (SC-59) and has a maximum collector current of -100 mA and a collector-emitter voltage of -50 V. The device operates with a junction temperature up to 150°C and has a power dissipation of 200 mW. Complementary NPN types are available in the DTC143E series.
DTA143EKA is an digital transistor (Resistor built-in type transistor). Built-in bias resistors enable the configuration of an inverter circuit without connecting external input resistors.
These are the standard products of "digital transistors" which ROHM invented and marketed first in the world.
