The DTB543ZE is a PNP digital transistor with built-in bias resistors in an SOT-416 package, designed for inverter, interface, and driver applications. It has a maximum collector current of -500 mA and a supply voltage rating of -12 V. The device features input resistance R1 of 4.7 kΩ and R2 of 47 kΩ, with a resistance ratio of R2/R1 of 10. It operates with a junction temperature up to 150 °C and dissipates up to 150 mW. The transistor includes thin-film resistors for reduced parasitic effects and supports DC current gain of at least 140 at -100 mA output current.
