DTB113ZK is a digital transistor from ROHM with a rated current and voltage of -500mA / -50V. The transistor has built-in bias resistors, so no external input resistors are required to configure an inverter circuit. The transistor's structure is PNP type silicon transistor and the package type is SMT3.
The DTB113ZK is a PNP epitaxial planar silicon digital transistor with built‑in thin‑film bias resistors, allowing inverter or driver circuits without external resistors. It is intended for applications such as inverters, interfaces, and drivers in audio‑visual, office‑automation, communication, and consumer electronic equipment.
Key specifications include a 50 V supply rating, -10 V to +5 V input range, 500 mA output current, 200 mW power dissipation, 150 °C junction temperature, and a typical transition frequency of 200 MHz. The device is supplied in an SMT3 package (code 7146) with standard dimensions and absolute maximum ratings listed in the sheet.
