RN2408,LXHF

Overview

The RN2408,LXHF is a single PNP digital transistor manufactured by Toshiba Semiconductor and Storage, designed for automotive applications. It integrates a built-in bias resistor with a base resistance (R1) of 47 kΩ. The device features a maximum collector-emitter voltage (VCEO) of -50 V and a continuous collector current (IC) of -100 mA. It operates within a junction temperature range of -40°C to +150°C and has a power dissipation rating of 200 mW. The component is AEC-Q101 qualified and housed in an SOT-346 package.

Feature Summary

• Single PNP configuration with integrated 47 kΩ base resistor
• AEC-Q101 qualified for automotive reliability standards
• High thermal stability with operation up to +150°C

Applications

• Automotive switching circuits
• Inverter control interfaces
• Driver circuit logic levels

Procurement Notes

Verify the specific suffix against official Toshiba documentation to confirm package type and qualification status. Ensure compatibility with automated placement equipment for the SOT-346 form factor. Confirm RoHS compliance requirements with the supplier prior to ordering.

Selection Notes

Select this component when a single PNP digital switch with high voltage tolerance (-50V) is required. The 47 kΩ internal resistor simplifies design by reducing external component count. Consider the 200 mW power dissipation limit for thermal management in dense PCB layouts.

Part Context

This part belongs to Toshiba's RN series of pre-biased transistors, which combine bipolar junction transistors with internal resistors. The series is optimized for space-constrained designs and offers consistent performance across automotive temperature ranges, replacing multiple discrete components.

Replacement Considerations

Check for direct substitutes such as RN2409 or RN2410 if different resistance values are acceptable. Verify pinout compatibility before substituting with other manufacturers' SOT-346 digital transistors.
