The DTB543ZM is a PNP digital transistor with built-in bias resistors in an SOT-723 package, designed for inverter, interface, and driver applications. It has a collector current rating of -500 mA and a supply voltage rating of -12 V. The device features input resistors R1 = 4.7 kΩ and R2 = 47 kΩ, enabling simplified inverter circuit design without external resistors. It operates with a maximum junction temperature of 150 °C and a storage temperature range of -55 °C to +150 °C. The package is taped in 8 mm width reels with a 180 mm reel size and 8,000 pieces per reel. The part meets no specified industry standards beyond its electrical and thermal ratings.
