The RN2108 is a monolithic silicon transistor array manufactured by Toshiba Semiconductor and Storage. It integrates multiple transistors in a single package. These arrays are often used for digital logic, interface, and driver applications, where multiple switching elements are needed in close proximity.

Applications

• Digital logic circuits
• Interface circuits
• Driver circuits
• Relay drivers
• LED drivers

Features

• Multiple transistors in one package: Saves board space and simplifies assembly.
• NPN transistors: General-purpose transistors suitable for a variety of applications.
• High current gain: Provides good amplification characteristics.
• Low saturation voltage: Minimizes power dissipation when the transistor is switched on.

Benefits

• Reduced board space: Integration of multiple transistors lowers the component count and saves space.
• Simplified design: Using a transistor array can simplify the circuit layout and reduce the number of external components.
• Improved performance: Closely matched transistors can improve the overall performance of the circuit.
• Cost-effective: Reduces component purchasing and assembly costs.

Technical Specifications

The RN2108 typically consists of four NPN transistors. Each transistor has a collector current rating of 100mA, a collector-emitter voltage rating of 50V, and a power dissipation rating of 300mW. The current gain (hFE) is typically between 100 and 300. The package is typically an 8-pin small outline package (SOP).
