The DTC143ZKA is an NPN digital transistor with built-in bias resistors (R1 = 4.7 kΩ, R2 = 47 kΩ) in a SOT-346 package, designed for inverter, interface, and driver applications. It has a maximum collector current of 100 mA and a supply voltage rating of 50 V. The device features an output saturation voltage of up to 300 mV at 5 mA collector current and a DC current gain of at least 80 at 10 mA collector current. Power dissipation is rated at 200 mW, and the junction temperature range extends to 150 °C. The part complies with RoHS standards.
DTC143ZKA is a digital transistor suitable for inverter, interface and driver applications.
These are the standard products of "digital transistors" which ROHM invented and marketed first in the world.
