DTA123J series is ROHM's PNP type digital transistor. This series has built-in bias resistors, external input resistors are not required to build inverter circuits, and the internal bias resistors are isolated thin-film resistors that can completely eliminate parasitic effects.
The DTA123J series are PNP digital transistors featuring built‑in biasing resistors, enabling inverter and driver circuits without external resistors. They are offered in multiple surface‑mount packages and are RoHS compliant.
Key data include a -50 V supply rating, -100 mA maximum collector current, 100 MHz transition frequency, and various package options such as SOT‑416, SOT‑346, and SOT‑323. The sheet also lists absolute maximum ratings, electrical characteristics, and detailed mechanical dimensions for each package.
