DTB143EK is a PNP digital transistor with built-in bias resistors for inverter, interface, and driver applications, housed in a SOT-346 package. It has a collector voltage rating of -50 V and a collector current rating of -500 mA, with a power dissipation limit of 200 mW. The device features integrated input resistors R1 and R2, each rated at 4.7 kΩ, enabling simplified circuit design without external components. The junction temperature range is -55 °C to +150 °C, and the DC current gain ranges from 47 to over 47 at -50 mA collector current. It is available in reel packaging with tape width of 8 mm and 3000 units per reel.
