RN4901,LXHF(CT

Overview

The RN4901,LXHF(CT is a dual pre-biased BJT array manufactured by Toshiba Semiconductor and Storage, housed in the US6 surface-mount package. It integrates one NPN and one PNP transistor with built-in bias resistors (R1=4.7kΩ, R2=4.7kΩ). Key electrical parameters include a maximum collector current of 100mA, a collector-emitter breakdown voltage of 50V, and a transition frequency of 200MHz to 250MHz. The device supports a maximum power dissipation of 200mW and operates up to +150°C. It holds AEC-Q101 automotive qualification.

Feature Summary

• Integrates complementary NPN and PNP transistors with fixed internal bias resistors to simplify circuit design.
• Automotive-grade reliability certified under AEC-Q101 standards for harsh environment operation.
• Compact US6 package reduces component count and manufacturing process steps.

Applications

• Switching circuits
• Inverter circuits
• Interface circuits
• Driver circuits

Procurement Notes

Verify the specific suffix LXHF(CT against the official Toshiba datasheet to confirm pinout compatibility and resistor values. Ensure the order quantity matches the manufacturer's standard reel size or cut tape requirements. Confirm RoHS compliance status and lead times directly with authorized distributors prior to finalizing procurement plans.

Selection Notes

Select this component when a compact solution requires both NPN and PNP switching capabilities with integrated base drive resistors. The 4.7kΩ resistor values are suitable for standard logic interface applications. Consider the 200mW power dissipation limit and thermal management requirements for high-density PCB layouts.

Part Context

This part belongs to the RN4901 series of digital transistors from Toshiba. It is functionally equivalent to the RN4901,LF variant but may differ in packaging or trailing specifications defined by the LXHF(CT suffix. It serves as a direct replacement for discrete resistor-transistor networks in space-constrained designs.

Replacement Considerations

The RN4901,LF is a verified alternative within the same product family. Verify that the LF suffix does not alter the electrical characteristics or package dimensions before substitution.
