RN2401,LXHF

Overview

The RN2401,LXHF is a PNP digital transistor manufactured by Toshiba Semiconductor and Storage, designed for automotive applications under the AEC-Q101 qualification standard. It integrates a single PNP bipolar junction transistor with built-in bias resistors in an SC-70 (SOT-323) surface-mount package. Key electrical parameters include a maximum collector-emitter voltage of -50V and a continuous collector current of -0.1A. The device features a typical input resistance of 4.7 kOhms and a typical resistor ratio of 1. DC current gain (hFE) is specified with a minimum value of 70. Operating frequencies reach up to 200 MHz or 250 MHz depending on test conditions, with a maximum power dissipation of 200mW.

Feature Summary

• Automotive-grade reliability compliant with AEC-Q101 standards
• Integrated bias resistors simplify circuit design and reduce component count
• Compact SC-70 surface-mount package suitable for space-constrained layouts

Applications

• Switching circuits in automotive electronic control units
• Inverter circuit drive stages
• Interface connection logic level shifting
• Driver circuit base driving

Procurement Notes

Verify the specific suffix LXHF against the official Toshiba datasheet to confirm package type and tape-and-reel specifications. Ensure the procurement channel provides valid traceability documentation required for automotive-grade components. Confirm RoHS compliance status through the manufacturer's latest certification records before finalizing orders.

Selection Notes

Select this component when a PNP configuration with integrated biasing is required for automotive environments. Compare the 4.7kOhm input resistance against other series variants like RN2409 if different bias ratios are needed. Verify that the -50V rating meets the system's voltage headroom requirements and that the SOT-323 footprint matches the PCB layout constraints.

Part Context

This part belongs to Toshiba's RN series of pre-biased transistors, which combine NPN or PNP transistors with internal resistors to replace multiple discrete components. The RN2401 specifically addresses the need for simplified driver circuits in automotive systems where space and assembly efficiency are critical. It serves as a direct replacement for older discrete BJT-resistor combinations in legacy designs.

Replacement Considerations

Publicly confirmed substitute part numbers for RN2401,LXHF were not identified in the provided source material. Engineers should consult Toshiba's official cross-reference guides or equivalent automotive-grade PNP digital transistors from other manufacturers, ensuring matching VCEO, IC, and package dimensions.
