RN4910,LXHF(CT

Overview

The RN4910,LXHF(CT is a digital transistor array manufactured by Toshiba Semiconductor and Storage, featuring one NPN and one PNP pre-biased transistor within a US6 surface-mount package. It operates with a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. The device includes built-in bias resistors, typically 4.7 kOhms for both base and emitter connections, simplifying circuit design. With a power dissipation rating of 200 mW and a transition frequency up to 250 MHz, it supports high-speed switching applications. The component meets AEC-Q101 automotive qualification standards.

Feature Summary

• Integrates dual pre-biased transistors (NPN and PNP) in a compact US6 package
• Includes built-in bias resistors to reduce external component count
• Automotive-grade reliability certified under AEC-Q101 standards

Applications

• Automotive electronic control units requiring reliable switching
• Interface circuits for logic level translation
• Driver circuits for low-power loads

Procurement Notes

Verify the specific suffix LXHF(CT against official Toshiba documentation to confirm packaging format and tape-and-reel specifications. Ensure the procurement channel provides traceability to Toshiba Semiconductor and Storage. Confirm RoHS compliance status and check for any recent product change notices that may affect marking or pin configuration before finalizing orders.

Selection Notes

Select this component when a dual digital transistor solution is required in a small footprint. The 4.7 kOhm internal resistor values are suitable for standard logic interfaces. Consider the 50 V breakdown voltage and 100 mA current limit for load requirements. The US6 package is ideal for space-constrained PCB layouts compared to larger SOT packages.

Part Context

This part belongs to the RN49xx series of digital transistors from Toshiba. It shares the same electrical characteristics as the RN4910,LF but differs in packaging and automotive qualification. The LXHF variant specifically denotes the US6 package form factor optimized for automated surface-mount assembly processes.

Replacement Considerations

RN4910,LF serves as a non-automotive equivalent with identical electrical parameters. Verify package compatibility between US6 variants. No direct cross-brand substitutes are confirmed in public documentation without detailed parameter matching.
