When it comes to transistors and bipolar junction transistor (BJT) arrays, the RN4902 is one of the most reliable, cost-effective options. This transistor is a standard surface-mount pre-biased NPN array based on industry leading designs. The RN4902 is well-suited for continuous current, collector-to-emitter voltage, and peak power applications.

The RN4902 is a four-terminal device consisting of four NPN type BJTs arranged in a common collector configuration. All four BJTs have their emitters connected together and their respective collectors connected to the four terminals, designated as COL-1, COL-2, COL-3 and COL-4. A common emitter terminal (MAN+), is available to externally connect both emitters together. A collector voltage (VCC) is available to externally bias the BJTs.

The RN4902 has a wide range of operating temperatures, from -55°C to + 125°C, with a maximum peak current rating of 3.2A. It also has an impressive peak power rating of 120W, making it a great option for applications with high-power requirements. Additionally, it has a collector-to-emitter voltage rating of -30V and a capacitance range from 2.7 to 3.2nF.

The RN4902 has a wide array of applications in the Circuit and control Technology field. Due to its pre-biased design, the RN4902 can be used to easily connect multiple devices in parallel without having to individually adjust the bias voltage. This makes it an ideal choice for parallel connected sensors and detectors, as well as power and non-inverting switching applications. It can also be used to create LED drivers, LED blinking, and light dimming, as well as in power amplifiers and high-power switching applications.

In terms of its working principle, the RN4902 is controlled by either collector current or emitter voltage. When the emitter voltage is increased, the collector current will increase accordingly, and vice versa. This means that the RN4902 can function as an amplifier or a switch, depending on the level of current applied to the collector. Additionally, by adjusting the collector voltage, the current through the collector can be easily regulated.

To sum it up, the RN4902 is an excellent choice for transistors and bipolar junction transistors (BJT) arrays, thanks to its low cost, high performance, and wide range of applications. It is well suited for both continuous current and peak power applications, and its pre-biased design makes it perfect for applications that require multiple devices to function together. Additionally, its working principle is controlled by either collector current or emitter voltage, which allows it to act both as an amplifier and a switch. All in all, the RN4902 is a great option when it comes to BJT arrays.
