RN4904,LXHF(CT

Overview

The RN4904,LXHF(CT is a dual digital transistor array manufactured by Toshiba Semiconductor and Storage, featuring one NPN and one PNP pre-biased transistor within a US6 (SOT-363) surface-mount package. It is qualified under the AEC-Q101 automotive standard for reliability in harsh environments. The device supports a maximum collector-emitter voltage of 50V and a continuous collector current of 100mA, with a power dissipation rating of 200mW. Internal biasing resistors are configured at 4.7kOhms for both R1 and R2, providing a symmetric resistance ratio of 1. The component operates up to a maximum junction temperature of +150°C and offers transition frequencies of 200MHz and 250MHz.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q101 standards for enhanced durability
• Integrated dual configuration combining NPN and PNP transistors in a single compact package
• Symmetric internal biasing network with equal base and emitter resistor values

Applications

• Automotive electronic control units requiring robust switching capabilities
• General-purpose logic level translation circuits
• Driver stages for low-power loads in consumer electronics

Procurement Notes

Verify the specific suffix LXHF against the manufacturer's latest documentation to confirm lead-free status and halogen-free compliance. Ensure the ordering quantity matches the reel or cut-tape specifications provided by authorized distributors. Cross-reference the AEC-Q101 certification details directly with Toshiba Semiconductor and Storage to validate automotive suitability for your specific application environment.

Selection Notes

Select this component when a matched NPN/PNP pair with identical biasing characteristics is required for differential or push-pull configurations. The US6 package is suitable for high-density PCB layouts where space is constrained. Consider the 50V voltage rating and 100mA current limit to ensure operation remains within safe thermal and electrical boundaries during peak load conditions.

Part Context

This part belongs to the Toshiba RN49xx series of digital transistors, which are designed to replace discrete resistor-transistor combinations. The RN4904 variant specifically utilizes a symmetric 4.7kOhm/4.7kOhm resistor network. It serves as a direct functional equivalent to other industry-standard dual digital transistors but offers Toshiba's specific automotive-grade reliability enhancements and packaging technology.

Replacement Considerations

Publicly confirmed substitute part numbers for RN4904,LXHF(CT were not found in the provided source material. Verify compatibility with generic SOT-363 dual digital transistors only after confirming pinout and electrical parameter alignment with official datasheets.
