RN4906FE,LXHF(CT

Overview

The RN4906FE,LXHF(CT is a bias resistor built-in transistor manufactured by Toshiba Semiconductor and Storage. It integrates an NPN transistor with internal bias resistors into a US-6 surface-mount package. The device features a collector-emitter voltage rating of 50 V and a continuous collector current capacity of 100 mA. Internal resistance values include a typical base resistor (R1) of 4.7 kΩ and an emitter resistor (R2) of 470 Ω, resulting in a standard resistor ratio of 0.1. The component meets AEC-Q101 automotive qualification standards and supports a maximum power dissipation of 200 mW.

Feature Summary

• Integrates NPN transistor with dual bias resistors to reduce external component count
• Automotive-grade reliability compliant with AEC-Q101 standards
• Compact US-6 surface-mount package for space-constrained designs

Applications

• Switching circuits requiring compact form factors
• Interface circuits for logic level translation
• Driver circuits for low-power loads

Procurement Notes

Verify the specific LXHF suffix against the manufacturer's latest datasheet to confirm tape-and-reel specifications and moisture sensitivity levels. Ensure the ordering code matches the required packaging format for automated assembly processes. Cross-reference the part number with authorized distributors to confirm current availability status.

Selection Notes

Select this component when a single NPN digital transistor with a 4.7 kΩ base resistor is required. The fixed resistor ratio simplifies circuit design compared to discrete components. Verify that the 50 V voltage rating and 100 mA current limit align with the target application's electrical requirements before finalizing the bill of materials.

Part Context

This part belongs to the RN4906 series of pre-biased transistors from Toshiba. The series offers various resistor combinations within the same US-6 footprint. The FE suffix typically denotes specific packaging or processing variations within the broader product family, distinguishing it from standard LF or CT variants.

Replacement Considerations

Direct substitutes include other RN4906 variants with identical electrical characteristics but different packaging suffixes. Cross-brand equivalents require matching the 50 V rating, 100 mA current, and US-6 package dimensions. Verify pinout compatibility before implementation.
