RN2903,LXHF(CT

Overview

The RN2903,LXHF(CT is an automotive-grade dual PNP Bias Resistor Built-in Transistor (BRT) from Toshiba. It integrates two transistors with base resistors in a US-6 (SOT-363) surface-mount package. Key electrical parameters include a collector-emitter voltage (VCEO) of -50 V, continuous collector current of -100 mA, and power dissipation of 200 mW. The typical base resistor value is 22 kΩ for both channels. The device features a minimum DC current gain (hFE) of 70 at -10 mA and -5 V, with a maximum operating frequency of 200 MHz. It is qualified under AEC-Q101 standards.

Feature Summary

• Integrates dual PNP transistors with built-in biasing resistors to simplify circuit design
• Automotive qualification compliant with AEC-Q101 standards for reliability
• Point-symmetrical configuration facilitates balanced signal processing applications

Applications

• Automotive electronic control units requiring dual switching functions
• General-purpose logic level translation circuits
• Driver stages for low-power loads in automotive environments

Procurement Notes

Verify the specific suffix LXHF(CT) against official Toshiba documentation to confirm tape-and-reel packaging specifications and automotive grade compliance. Ensure that the US-6 package dimensions match the target PCB footprint requirements. Cross-reference the AEC-Q101 qualification status directly with the manufacturer's latest datasheet to validate suitability for automotive applications.

Selection Notes

Select this component when dual PNP switching with integrated biasing is required in space-constrained automotive designs. The 22 kΩ base resistance offers a standard trade-off between drive current and input impedance. Consider the 200 MHz switching speed and 200 mW thermal limits for high-frequency or higher-current applications within the specified temperature range.

Part Context

This part belongs to Toshiba’s RN29xx series of Bias Resistor Built-in Transistors designed for automotive use. The series provides compact solutions by combining transistors and resistors in single packages. The RN2903 specifically utilizes a point-symmetrical dual PNP configuration, distinguishing it from single-channel or NPN variants within the broader family.

Replacement Considerations

Direct substitutes may include other automotive-grade dual PNP BRTs in SOT-363 packages with similar 50V ratings and 22kΩ base resistors. Verify pinout symmetry and hFE characteristics before substitution.
