RN4907, LF Application Field and Working Principle

The RN4907 is a type of Pre-Biased Bipolar Transistor Array. It consists of 4 independent NPN transistors with pre-biased emitters in a dual in-line package that is designed for use in low-frequency (LF) applications. It is ideal for general switching and amplifier applications. This type of transistor array is designed to meet demanding requirements for physical, electrical and thermal characteristics.

Features

• 4 independent NPN transistors
• Pre-biased emitters
• LF applications
• General switching or amplifier applications
• Meets demanding requirements for physical, electrical and thermal characteristics

Applications

• Low-Frequency (LF) applications

Working Principle

In the RN4907 Pre-Biased Bipolar Transistor Array, each of the 4 NPN transistors have a pre-biased emitter. This provides an already established base current path from the emitter to the collector, allowing for fast transistor switching when the base is activated. The pre-biased emitter also allows for current to flow more easily throughout the array, improving the transistor’s performance in LF applications.

This type of transistor array is designed for low-frequency applications, such as motors, relays, and solenoids. It also has a wide operating temperature range from -65°C to +175°C. Additionally, the RN4907 is pin-compatible with other 4-transistor arrays, making it a highly versatile product.

Conclusion

The RN4907 Pre-Biased Bipolar Transistor Array is a versatile type of transistor array that is designed for use in low-frequency (LF) applications. It consists of 4 independent NPN transistors with pre-biased emitters in a dual in-line package and offers excellent performance in LF applications. It is also designed to meet demanding requirements for physical, electrical and thermal characteristics. This particular array is ideal for motors, relays, and solenoids, and is pin-compatible with other 4-transistor arrays.
