UMA1N / FMA1A are complex digital transistors (with built-in resistors) suitable for inverter, interface, driver applications. They feature two DTA124E chips, which can reduce mounting cost and area. The structure is PNP epitaxial planar silicon transistor (dual chips; each with two built-in resistors).
This handbook describes the UMA1N and FMA1A complex digital transistors, covering their applications, features, structure, and packaging. It includes absolute maximum ratings, electrical characteristics, and example circuit diagrams.
Key specifications include a collector current of up to 100 mA, a supply voltage rating of –60 V, and a junction temperature limit of 150 °C. The devices are offered in UMT5 and SMT5 tape‑and‑reel packages and are intended for use in general electronic equipment.
| Supply voltage | -60 V |
|---|---|
