This document describes the features and dimensions of several general purpose PNP silicon transistors produced by ROHM. These products have excellent hFE linearity and can be used in conjunction with other models of silicon transistors.
This ROHM data sheet describes a family of general‑purpose PNP silicon transistors (2SA1037AK, 2SA1576A, 2SA1774, 2SA2029). It lists features such as excellent linearity and provides the same dimensions for all devices. The document includes absolute maximum ratings, typical electrical characteristics, and packaging information.
The sheet also contains characteristic curves, recommended application notes, and a notice about usage restrictions. It specifies storage conditions, safety considerations, and the intended use in general‑purpose electronic equipment.
