RN2406,LF

Overview

The RN2406,LF is a digital transistor manufactured by Toshiba Semiconductor and Storage. It integrates a single PNP bipolar junction transistor with built-in bias resistors in an S-Mini (SOT-23) surface-mount package. The device supports a maximum collector-emitter voltage of 50V and a continuous collector current of 100mA. Key electrical characteristics include a DC current gain (hFE) minimum of 80 at 10mA and 5V, and a saturation voltage of 300mV at 250µA base current and 5mA collector current. The unit features a transition frequency of 200MHz and a maximum power dissipation of 200mW. Internal resistor values are specified as R1=47kΩ and R2=10kΩ.

Feature Summary

• Integrates a PNP transistor with dual bias resistors for simplified circuit design
• Provides high-speed switching capability with a 200MHz transition frequency
• Offers low saturation voltage to minimize power loss during conduction
• Utilizes compact S-Mini packaging for efficient space utilization

Applications

• Switching circuits requiring fast response times
• Inverter circuits for signal inversion
• Interface circuits connecting logic levels
• Driver circuits for small-signal loads

Procurement Notes

Verify the specific ordering suffix and tape-and-reel specifications against the manufacturer's latest datasheet before procurement. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the supplier provides official documentation to validate authenticity and traceability of the component batch.

Selection Notes

Select this component when a pre-biased PNP transistor is required for interface or driver applications. The integrated 47kΩ base resistor and 10kΩ emitter resistor simplify bias network design compared to discrete solutions. Consider the 200mW power dissipation limit and S-Mini package thermal constraints for your specific operating environment and load conditions.

Part Context

The RN2406,LF belongs to Toshiba's RN series of digital transistors, which combine bipolar junction transistors with internal bias resistors. This series is designed to reduce board space and simplify circuit layouts by eliminating external resistor components. The part is commonly used in consumer electronics and industrial control systems where compact, reliable switching elements are needed.

Replacement Considerations

Publicly confirmed substitute part numbers for the RN2406,LF were not found in the provided source material. Verify compatibility with alternative digital transistors by matching the PNP configuration, 50V VCEO rating, 100mA IC limit, and similar resistor ratios (R1/R2 ≈ 4.7). Consult manufacturer cross-reference guides for qualified equivalents.
