RN2406,LXHF

Overview

The RN2406,LXHF is a PNP digital transistor from Toshiba Semiconductor and Storage, designed for automotive applications with AEC-Q101 qualification. It features an integrated bias resistor network within a compact US-6 (SOT-363) surface-mount package. Key electrical specifications include a maximum collector-emitter voltage (VCEO) of -50 V and a continuous collector current (IC) of -100 mA. The device incorporates typical internal resistors of R1=4.7 kΩ and R2=47 kΩ, providing a resistance ratio of approximately 0.1. It operates at a maximum junction temperature of +150°C with a power dissipation rating of 200 mW.

Feature Summary

• Automotive-grade reliability certified under AEC-Q101 standards
• Integrated dual-resistor network simplifies circuit design
• Compact SMD packaging suitable for high-density layouts

Applications

• Switching circuits in automotive systems
• Inverter circuit interfaces
• Driver circuit logic levels

Procurement Notes

Verify the specific suffix LXHF against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Confirm that the US-6 package matches the target PCB footprint. Ensure the ordering quantity aligns with standard reel sizes if bulk procurement is required.

Selection Notes

Select this component when a PNP digital transistor with a 4.7k/47k resistor ratio is required for automotive environments. Compare the -50V voltage rating and -100mA current capacity against load requirements. Consider the US-6 package dimensions for space-constrained designs compared to single-transistor alternatives.

Part Context

This part belongs to Toshiba's RN series of built-in bias resistor transistors. These devices replace discrete resistor networks, reducing board space and assembly costs. The RN24xx series specifically targets automotive switching and interface applications requiring robust performance under varying thermal conditions.

Replacement Considerations

Check for direct cross-reference part numbers from other manufacturers offering identical -50V PNP configurations with similar resistor ratios in SOT-363 packages. Verify pin-to-pin compatibility before substitution.
