The DTA114Y series PNP -100mA -50V Digital Transistors (Bias Resistor Built-in Transistors) have built-in bias resistors that enable the configuration of an inverter circuit without connecting external input resistors (see equivalent circuit). The bias resistors consist of thin-film resistors with complete isolation to allow negative biasing of the input. They also have the advantage of completely eliminating parasitic effects. Operation only requires setting the on/off conditions, making circuit design easy.
The DTA114Y series are PNP digital transistors with built‑in bias resistors, allowing inverter or switching circuits without external resistors. The series includes several package types such as SOT‑416, SOT‑323 and SOT‑346 and is lead‑free/ROHS compliant.
The document provides absolute maximum ratings, electrical characteristics, characteristic curves, and detailed mechanical dimensions for each variant (e.g., DTA114YE, DTA114YUB). It also contains packaging specifications and a legal notice from ROHM.
