XN01601 is a composite transistor from Toshiba. It consists of a silicon PNP epitaxial planer transistor (Tr1) and a silicon NPN epitaxial planer transistor (Tr2). XN01601 has two elements incorporated into one package (emitter-coupled transistors), which reduces the mounting area and assembly cost by half.
This document is a technical datasheet for the Panasonic XN01601 (also referenced as XN1601), which consists of two silicon epitaxial planar transistors incorporated into one package. The device includes a Silicon PNP transistor (Tr1) and a Silicon NPN transistor (Tr2), designed for general amplification applications.
The conventional part number for Tr1 is 2SB709A.
The products are intended to be used for standard applications or general electronic equipment such as office equipment, communications equipment, measuring instruments and household appliances.
