The DTC143EKA is an NPN digital transistor with built-in bias resistors R1 and R2, both rated at 4.7 kΩ, designed for inverter, interface, and driver applications. It employs the SOT-346 (SC-59) package and has a maximum collector current of 100 mA and collector-emitter voltage of 50 V. Power dissipation is rated at 200 mW, with a junction temperature range up to 150 °C and storage temperature from -55 to +150 °C. The transistor operates with on-off input conditions, eliminating the need for external resistors in basic circuits. Complementary PNP types are available in the DTA143E series.
DTC143EKA 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.
