RN1906FE(T5L,F,T)

Overview

The RN1906FE(T5L,F,T) is a dual NPN pre-biased transistor manufactured by Toshiba Semiconductor and Storage. It integrates two NPN silicon epitaxial transistors with built-in bias resistors in a single surface-mount package. The device supports a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. Key electrical specifications include a minimum DC current gain (hFE) of 80 at specified test conditions and a transition frequency of 250 MHz. The internal resistor configuration features a base resistor ratio of 0.1, facilitating simplified circuit design for switching applications.

Feature Summary

• Integrates dual NPN transistors with built-in bias resistors to reduce component count and board space.
• Utilizes Toshiba's PCT (Passive Component in Transistor) process technology for high reliability.
• Designed for general-purpose switching applications with optimized base resistance ratios.

Applications

• Switching circuits in consumer electronics
• Inverter circuits for logic level translation
• Interface and driver circuits for digital signals

Procurement Notes

Verify the complete part number including the suffix (T5L,F,T) to ensure correct tape-and-reel packaging and lead-free compliance. Confirm RoHS status and moisture sensitivity level requirements against specific manufacturing standards before ordering. Cross-reference with official Toshiba distribution channels to avoid counterfeit components.

Selection Notes

Select this component when a compact solution for dual NPN switching is required without external biasing networks. Ensure the 50 V collector-emitter voltage rating exceeds the maximum circuit voltage. Verify that the 100 mA collector current limit accommodates the load requirements. Consider the 250 MHz transition frequency for high-speed switching needs compared to standard discrete transistors.

Part Context

This part belongs to the RN1906 series of pre-biased transistors from Toshiba Semiconductor and Storage. The series utilizes the PCT process to combine transistors and resistors into a single small-outline package. Variants within the series differ primarily in resistor values and package types, offering flexibility for various interface and driver applications while maintaining consistent transistor performance characteristics.

Replacement Considerations

Compatible alternatives include other RN1906 variants such as RN1906AFS or RN1906FS, provided the resistor ratios match the design requirements. Verify pinout compatibility and thermal characteristics when substituting with similar dual pre-biased transistors from other manufacturers.
