Description
A683 is -25V, -1A, Silicon PNP epitaxial planer type transistor. A PNP epitaxial planar type transistor refers to a specific type of PNP (Positive-Negative-Positive) bipolar junction transistor (BJT) that is constructed using an epitaxial planar technology on a semiconductor substrate.
1. The transistor follows the PNP configuration, which means it has a P-type semiconductor region sandwiched between two N-type regions. The transistor consists of three layers: the emitter (P-type), the base (N-type), and the collector (P-type).
2. Application: PNP epitaxial planar type transistors find applications in various electronic circuits, including amplifiers, switches, voltage regulators, oscillators, and other applications that require amplification or signal switching.
