The DTA143XKA is a PNP digital transistor with built-in bias resistors, designed for inverter, interface, and driver applications. It is packaged in an SOT-346 case, measuring 2.9mm × 2.8mm, and supports a maximum collector current of -100mA and a collector-emitter voltage of -50V. The input resistance R1 is specified at 4.7kΩ, with an R2/R1 resistance ratio of 2.1. Operation is enabled by setting only on/off conditions, eliminating the need for external resistors. The device operates with a maximum junction temperature of 150°C and a storage temperature range of -55°C to +150°C.
