2SA
2SA is a semiconductor device known as a PNP bipolar junction transistor (BJT). It is widely used in electronic circuits for amplification and switching applications. The designation "2SA" is part of a standardized naming convention for transistors, where "2S" indicates a signal transistor, and "A" denotes a specific version within that series.
The 2SA transistor typically features a high current gain (hFE) and low saturation voltage, making it suitable
In terms of construction, the 2SA is a three-layer, two-junction device composed of semiconductor material, usually
The 2SA transistor has been used in various applications such as audio amplifiers, signal processing, and switching
While traditional, the 2SA remains relevant in certain niche applications and educational contexts due to its
