RN4907,LXHF(CT

Overview

The RN4907,LXHF(CT is a dual pre-biased transistor array manufactured by Toshiba Semiconductor and Storage, integrating one NPN and one PNP bipolar junction transistor within a single surface-mount package. This component features an integrated base resistor (R1) of 10 kΩ and an emitter resistor (R2) of 47 kΩ to simplify circuit design. It supports a maximum collector-emitter voltage (Vceo) of 50 V and a continuous collector current (Ic) of 100 mA. The device offers a DC current gain (hFE) of at least 80 at 10 mA and 5 V, with a transition frequency of 200 MHz and a maximum power dissipation of 200 mW. It is housed in a US6 (SOT-363) package.

Feature Summary

• Integrates complementary NPN and PNP transistors with built-in biasing resistors for simplified digital switching applications.
• Provides high-speed performance with a transition frequency of 200 MHz suitable for signal processing.
• Features automotive-grade qualification ensuring reliability under varying thermal conditions.

Applications

• Automotive electronic control units requiring AEC-Q101 qualified components.
• Digital logic level shifting and interface circuits between microcontrollers and peripherals.
• General-purpose switching applications in consumer electronics and industrial equipment.

Procurement Notes

Verify the specific suffix LXHF(CT) against the manufacturer's latest datasheet to confirm compliance with RoHS3 directives and lead-free specifications. Ensure the ordering code matches the required tape-and-reel packaging format for automated assembly processes. Cross-reference the part number with official Toshiba documentation to validate current production status and availability constraints before finalizing procurement plans.

Selection Notes

Select this component when a compact solution for both NPN and PNP switching is required within a limited board space. The fixed internal resistor values of 10 kΩ and 47 kΩ are optimized for standard logic levels; verify these match your drive requirements. Consider the 200 mW power dissipation limit and thermal management needs for the US6 package in dense layouts.

Part Context

This part belongs to the RN49xx series of digital transistors from Toshiba, designed as direct replacements for discrete resistor-transistor networks. The LXHF(CT) suffix indicates specific automotive-grade manufacturing and cut-tape packaging options. It shares the same electrical characteristics as the standard RN4907,LF but adheres to stricter automotive quality standards.

Replacement Considerations

Direct substitutes include the RN4907,LF for non-automotive applications or other RN49xx variants with matching resistor ratios if different biasing is needed. Verify pinout compatibility with the SOT-363/US6 footprint when considering alternatives from other manufacturers.
