XN0221100L Application Field and Working PrincipleXN0221100L is a Pre-Biased Bipolar Junction Transistor (BJT) Array manufactured by X-FAB. It is an advanced industry-standard NPN transistor array without current-limiting resistors and with thermal feedback for linear operation. This transistor array is designed to be operated in the linear region, so it has excellent temperature stability and high gain. The XN0221100L is suitable for use in applications such as optical sensing, communications, and industrial control.OverviewXN0221100L is a high-performance, high-reliability transistor array made up of eight monolithic NPN transistors. Each transistor has a dielectric isolation to guarantee that neither positive nor negative parasitic resistances occur in the circuit. It is specially designed for use in linear applications where its high gain provides excellent temperature stability.The device is built to a 4.5 x 4.5 mm MQFP (Medium Quad Flat Package) that comes with an on-chip temperature compensation circuit, which allows for linear operation over a wide temperature range. Its maximum operating temperature extends up to 135° C, allowing for a remarkably long life cycle.The transistors are also pre-biased, so no additional external components are required. This makes the XN0221100L ideal for applications where low power is critical.Features and BenefitsThe XN0221100L is designed to offer exceptional performance and reliability. It features eight independent transistors, which can be used to switch loads up to 1 A of current, making it suitable for applications requiring large loads, such as motor control, lamp switching and general power management.The device also has a low thermal resistance, making it capable of dissipating up to 1 W of power while keeping temperatures low. For maximum efficiency, X-FAB has designed the device to enable a maximum gain of 45, making sure that it is able to deliver better results than conventional devices.In addition, the device is lead-free, RoHS compliant, and meets exacting industry standards for quality and reliability. All this combines to make the XN0221100L a perfect choice for the most demanding applications.Working Principle and ApplicationsAt its most basic level, the XN0221100L is a pre-biased horizontal NPN transistor array. Each device is composed of eight NPN transistors connected in an array, with each transistor providing a low resistance to ground.When the transistors are switched on, current flows from the collector to the emitter, allowing for maximum efficiency. The pre-biased configuration ensures that the circuit does not require any additional external components for operation.The XN0221100L is suitable for applications such as optical sensing, communications and industrial control. In these applications, the XN0221100L’s excellent gain and temperature stability allow for reliable and accurate measurements even in noisy or rapidly changing conditions.Because it is lead-free and RoHS compliant, the XN0221100L is also a suitable choice for use in green, eco-friendly designs. Additionally, its small size and low power requirements make it suitable for applications with space and power constraints.ConclusionThe XN0221100L is a reliable and high-performance BJT Array designed especially for linear applications that demand high gain and temperature stability. It is pre-biased, which eliminates the need for external components, and can handle up to 1 A of load. In addition to this, it features a high-reliability build and is compliant with Green standards. The XN0221100L is therefore suitable for a wide variety of applications where linear operation is of utmost importance.
