The DTB543EE is a PNP digital transistor with built-in bias resistors, packaged in a SOT-416 (EMT3) case, 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 internal bias resistors are both 4.7 kΩ, enabling input circuit simplicity without external components. Power dissipation is rated at 150 mW, with a junction temperature range of -55 °C to +150 °C and a maximum storage temperature of +150 °C. The device meets standard surface-mount mounting requirements and is supplied in 3000-piece tape-and-reel packaging.
