DTA044E series is a PNP digital transistor from ROHM. It has a rated current of -100mA and a rated voltage of -50V. It has built-in bias resistors, so no external input resistors are required to form an inverter circuit. It is suitable for switching circuits, inverter circuits, interface circuits, and driver circuits
The DTA044EUB is a PNP digital transistor from ROHM that includes built‑in 47 kΩ bias resistors, enabling simple inverter or switching circuit designs without external resistors. It is RoHS‑compliant and offered in surface‑mount packages.
Key specifications include a supply voltage rating of –50 V, input voltage range –40 V to +10 V, maximum collector current of –100 mA, power dissipation of 200 mW, and a transition frequency of 250 MHz. Package dimensions and terminal layouts for the TL‑180 package are detailed, along with absolute maximum ratings and typical application circuits.
