RN49A2,LF is a series of pre-biased transistors made to be used in applications fields that require current transfer. The design of this transistor allows it to have a high gain, low saturation voltage and better thermal characteristics; it is used in a wide range of applications such as power supply design, analog to digital interfaces and in industrial applications. It is also used in temperature sensing, logic levels and display control, adc processing and high speed operation.

The mechanism of the RN49A2,LF is based on a bipolar junction transistor (BJT) structure. In BJT structure, the collector current is controlled by the base current, and a small base current amplification factor (β = hfe) is produced from the collector current to the base current ratio. The BJT is a three-terminal device where the two terminals are the base and the collector, and the third terminal is the emitter. A current-controlled current source is incorporated in the base-collector junction that forms two positive regions, the collector and the base, and one negative region, the emitter. A small but constant current flows from the collector to the base, creating the bias voltage required for the transistor circuit to operate. This bias voltage gives the base-collector junction a predefined ratio of current conduction which is known as the small current linearity ratio. The RN49A2,LF series transistors have a wide range of current linearity ratios, ranging from 1:2 up to 1A:10A.

Furthermore, the RN49A2,LF has excellent thermal characteristics making it suitable for temperature sensing applications. It has low thermal resistance and a very low temperature coefficient. The junction-to-case thermal resistance ranges from 2.2 °C/W to 2.7 °C/W depending on the size of the transistor. The temperature coefficient of the junction-to-case thermal resistance is also low, and the junction temperature rise is only 0.2°C/W.

The RN49A2,LF is designed to cover a wide range of automotive, industrial, and consumer applications. The range of application fields enabled by the RN49A2,LF transistors include data acquisition and control systems, temperature regulation, warning systems and security systems.
