RN2910,LXHF(CT

Overview

The RN2910,LXHF(CT is a dual PNP bias resistor built-in transistor (BRT) from Toshiba Semiconductor and Storage. It integrates two PNP transistors with internal base resistors in an SOT-363 (US6) surface-mount package. Key electrical parameters include a collector-emitter breakdown voltage (Vceo) of -50 V, a continuous collector current (Ic) of -100 mA, and a power dissipation (Pd) of 200 mW. The device features a typical input resistance of 4.7 kΩ for the first transistor and infinite resistance for the second, with a maximum operating frequency of 200 MHz.

Feature Summary

• Integrates dual PNP transistors with pre-biased resistors to simplify circuit design
• Utilizes compact SOT-363 (US6) surface-mount packaging for space efficiency
• Supports high-speed switching applications with a maximum operating frequency of 200 MHz

Applications

• General-purpose digital switching circuits
• Logic level translation interfaces
• Driver stages for small-signal loads

Procurement Notes

Verify the specific suffix LXHF(CT) against the official Toshiba datasheet to confirm the exact internal resistor configuration and tape-and-reel specifications. Ensure that the ordering part number matches the required pinout and electrical characteristics for your design. Cross-reference the manufacturer's latest documentation to confirm compliance with RoHS directives and automotive qualification standards if applicable to your project requirements.

Selection Notes

Select this component when a dual PNP BRT solution is required with a 50V rating and 100mA current capacity. The integrated 4.7kΩ base resistor simplifies drive circuitry compared to discrete transistors. Consider the SOT-363 footprint constraints and thermal dissipation limits of 200mW during layout. Verify that the dual configuration meets the logical inversion needs of the application without requiring additional external components.

Part Context

This component belongs to Toshiba’s RN series of Bias Resistor Built-in Transistors, designed to replace multiple discrete components. The RN2910 specifically offers a dual PNP configuration within a US6 package. This series is engineered to reduce board space and assembly costs while maintaining reliable performance in consumer electronics and industrial control systems requiring compact, pre-biased switching elements.

Replacement Considerations

Direct substitutes may include other dual PNP BRTs in SOT-363 packages with similar 50V/100mA ratings. Verify equivalent internal resistor values and hFE characteristics before substitution. Check pin compatibility and thermal performance metrics to ensure seamless integration into existing PCB layouts without redesign.
