A684 is -50V, -1A, Silicon PNP epitaxial planar type transistor.

A silicon 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 silicon substrate.

1 PNP Configuration: 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. 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.


• Complementary pair with 2SC1383 and 2SC1384

• Allowing supply with the radial taping
