RN2902FE,LXHF(CT

Overview

The RN2902FE,LXHF(CT is a PNP digital transistor from Toshiba Semiconductor and Storage, part of the AEC-Q101 qualified automotive series. It integrates two PNP transistors with built-in bias resistors in a single US-6 (SOT-363) surface-mount package. The device features a collector-emitter voltage (VCEO) of -50 V and a continuous collector current (IC) of -100 mA. Internal resistor values are typically 47 kOhms for R1 and 22 kOhms for R2, providing a ratio of approximately 2.14. Key electrical parameters include a minimum DC current gain (hFE) of 70, a maximum operating frequency of 200 MHz to 250 MHz, and a power dissipation (Pd) of 200 mW at an ambient temperature up to +150°C.

Feature Summary

• Automotive-grade reliability certified under AEC-Q101 standards for enhanced durability in vehicle environments.
• Dual PNP configuration with integrated bias resistors simplifies circuit design by reducing component count.
• Compact US-6 (SOT-363) surface-mount packaging enables high-density board layouts.

Applications

• Switching circuits in automotive electronic control units (ECUs).
• Inverter driver circuits for motor control applications.
• Interface connection buffers between microcontrollers and peripheral devices.
• General-purpose driver circuits requiring compact dual-transistor solutions.

Procurement Notes

Verify the specific suffix designation against official Toshiba documentation to confirm internal resistor configurations and tape-and-reel specifications. Ensure that the ordering code matches the required variant, as suffixes may indicate differences in packaging or specific electrical tolerances. Cross-reference the manufacturer's latest datasheet to confirm availability status and lead times prior to procurement planning.

Selection Notes

Select this component when a dual PNP digital transistor solution is required for automotive applications demanding AEC-Q101 compliance. The integrated 47k/22k resistor network suits interfaces needing specific base drive currents. Verify that the -50V VCEO rating exceeds the maximum circuit voltage and that the 200-250 MHz frequency response meets the switching speed requirements of the target application.

Part Context

This part belongs to Toshiba's automotive digital transistor family, designed specifically for robust performance in harsh environments. The RN2902FE variant utilizes the US-6 package, offering a space-efficient alternative to discrete transistor pairs. It complements other members of the RN series by providing pre-biased functionality, which reduces layout complexity and improves switching consistency in mass-produced automotive electronics.

Replacement Considerations

Publicly confirmed substitute part numbers for RN2902FE,LXHF(CT were not identified in the provided source material. Engineers should consult Toshiba's official replacement guide or distributor cross-reference tools for verified equivalents matching the US-6 package and -50V/-100mA specifications.
