UNR92A2G0L Application Field and Working Principle

The UNR92A2G0L transistor is a single-chip, pre-biased BJT (bipolar junction transistor) manufactured and supplied by UN Extension Technology Co., Ltd. It is an effective device for various types of detector applications, especially in surveillance systems, access control systems and home security systems.

UNR92A2G0L BJT has a built-in gain control and from bifurcation state (B/C) and has a low voltage drop over a wide range of current, making it a very reliable and cost-effective device for detector applications.

This transitor is suitable for use in high-speed, low-power electronics and video applications, as well as in low-end linear and logic applications.

The UNR92A2G0L BJT\'s working principle is based on the principle of current flow through a PN junction. In a PN junction, when the base current is increased, a high current flowing through the emitter-collector junction is achieved. This current is further increased by the addition of the current in the base circuit, which increases the total current flowing through the emitter-collector junction.

The resulting current (IC) flowing between the collector and emitter junction is proportional to the base current (IB) according to the following formula:

IC = β x IB

Where β is a factor that is typically between 100-200 depending upon the type of transistor used.

The UNR92A2G0L has an integrated voltage regulator, which helps it to maintain an optimal operating voltage. It also offers low saturation voltage and a wide range of input voltage. Additionally, the built-in gain control ensures that the output current remains constant, even with fluctuating input current.

The UNR92A2G0L offers several advantages including high input impedance, high stability, low noise and power consumption, and compatibility with 3.3V and 5V logic.

It is an excellent choice for various detector applications, including access control, surveillance systems, and home security.
