RN2409,LXHF

Overview

The RN2409,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 SOT-346 surface-mount package. Key electrical specifications include a collector-emitter breakdown voltage (VCEO) of -50V, a continuous collector current (IC) of -100mA, and a typical base resistor (R1) value of 4.7kΩ. The device features a DC current gain (hFE) minimum of 70 and supports operating frequencies up to 250MHz, making it suitable for high-speed switching and driver circuits.

Feature Summary

• Integrated PNP transistor with dual internal bias resistors for simplified circuit design
• Automotive-grade reliability certified to AEC-Q101 standards
• Compact SOT-346 surface-mount package for space-constrained applications

Applications

• Switching circuits in automotive electronic control units
• Inverter drive circuits for motor control
• Interface connection buffers between logic levels
• Driver circuits for low-power loads

Procurement Notes

Verify the specific suffix LXHF against the manufacturer's official datasheet to confirm pinout compatibility and resistance values. Ensure the procurement channel provides traceability documentation required for AEC-Q101 qualified components. Confirm that the supplier handles ESD-sensitive devices appropriately during storage and shipping.

Selection Notes

Select this component when a PNP configuration with integrated biasing is required for automotive environments. Compare the 4.7kΩ base resistor value against circuit requirements to ensure proper drive current. Verify that the SOT-346 footprint matches the PCB layout constraints and that the -50V rating exceeds the maximum expected load voltage.

Part Context

This part belongs to Toshiba's RN series of pre-biased transistors, which are optimized for automotive use. The RN2409 variant specifically denotes a PNP type with a 4.7kΩ base resistor, distinguishing it from NPN counterparts or variants with different resistance ratios within the same family.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Cross-referencing requires consulting official Toshiba replacement guides or distributor equivalence databases for compatible PNP digital transistors with identical VCEO, IC, and package specifications.
