The DTA143EM is a PNP digital transistor with built-in bias resistors (R1 = R2 = 4.7 kΩ) for simplified inverter circuit design, packaged in the VMT3 case (1212 size, 1.2 mm × 1.2 mm). It has a collector current rating of -100 mA, a collector-emitter voltage of -50 V, and a power dissipation of 150 mW. The junction temperature ranges from -55 °C to +150 °C. Complementary NPN types are available in the DTC143E series.
DTA143EM 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.
