RN2909FE,LXHF(CT

Overview

The RN2909FE,LXHF(CT is a PNP digital transistor array manufactured by Toshiba Semiconductor and Storage. It integrates two PNP transistors with built-in bias resistors in a compact US6 (SOT-363) surface-mount package. The device features a collector-emitter voltage of -50V and a continuous collector current of -100mA. Internal resistor values are typically 47kOhms and 22kOhms, yielding a ratio of approximately 2.14. It operates up to 200MHz or 250MHz depending on conditions, with a power dissipation of 200mW and a maximum junction temperature of +150°C. The component meets AEC-Q101 automotive qualification standards.

Feature Summary

• Integrates dual PNP transistors with pre-bias resistors for simplified circuit design
• Automotive-grade reliability compliant with AEC-Q101 standards
• Compact SMD packaging suitable for high-density board layouts

Applications

• Switching circuits
• Inverter circuits
• Interface circuits
• Driver circuits

Procurement Notes

Verify the specific suffix LXHF against the manufacturer's official datasheet to confirm internal resistance tolerances and tape-and-reel specifications. Ensure the ordering code matches the exact package variant required for your PCB footprint. Cross-reference the AEC-Q101 certification status if automotive compliance is mandatory for your production line.

Selection Notes

Select this component when a dual PNP configuration with integrated biasing is required for space-constrained designs. The US6 package offers a small footprint compared to discrete solutions. Verify that the 47k/22k resistor ratio aligns with your logic interface requirements and that the -50V rating exceeds your circuit's maximum operating voltage.

Part Context

This part belongs to Toshiba's RN series of built-in bias resistor transistors. These devices replace multiple discrete components, reducing board space and assembly costs. The FE suffix typically denotes a specific packaging or quality tier within the broader RN2909 family, often associated with automotive or high-reliability applications.

Replacement Considerations

Direct substitutes include other dual PNP BRTs in SOT-363 packages such as the RN2905 or RN2906 from Toshiba, provided resistor ratios match. Check equivalent offerings from ON Semiconductor or ROHM, ensuring VCEO and IC ratings meet or exceed the original specifications.
