The DTA123YKA is a PNP digital transistor with built-in bias resistors (R1 = 2.2 kΩ, R2 = 10 kΩ) in an SMT3 (SOT-346) package. It has a collector-emitter voltage rating of -50 V, a maximum collector current of -100 mA, and a power dissipation of 200 mW. The device is designed for inverter, interface, and driver applications, enabling simple on/off control without external resistors. Its junction temperature range is -55°C to +150°C, and it complies with RoHS standards. Complementary NPN types are available in the DTC123Y series.
These are the standard products of "digital transistors" which ROHM invented and marketed first in the world.
