This document is a datasheet for the DTA114T series PNP digital transistors produced by ROHM. The transistors feature built-in bias resistors, which allow the configuration of an inverter circuit without connecting external input resistors. The bias resistors consist of thin-film resistors with complete isolation, enabling negative biasing of the input and eliminating parasitic effects. Only the on/off conditions need to be set for operation, making the circuit design easy.
The DTA114T series from ROHM consists of PNP digital transistors with built‑in bias resistors, available in several SOT package types. The devices are lead‑free and RoHS compliant, making them suitable for a variety of switching, inverter, interface, and driver circuits.
Key data include maximum voltage ratings of 50 V, a collector current of –100 mA, power dissipation up to 150 mW, and a transition frequency of 250 MHz. Detailed mechanical drawings give the exact dimensions for each package variant, and the document also contains legal and usage notices.
