RN2111,LXHF(CT

Overview

The RN2111,LXHF(CT is a single PNP bias resistor built-in transistor (BRT) manufactured by Toshiba Semiconductor and Storage. It integrates a single PNP bipolar junction transistor with internal base resistors within an SOT-723 surface-mount package. The device features a collector-emitter breakdown voltage of -50V and a continuous collector current rating of -100mA. Internal resistance values are typically 47kΩ for the base resistor (R1) and 47kΩ for the emitter resistor (R2). The component is qualified under AEC-Q101 standards for automotive applications, ensuring reliability in demanding environments.

Feature Summary

• Integrates a PNP transistor with dual internal bias resistors to simplify circuit design
• Qualified for automotive electronics under AEC-Q101 reliability standards
• Utilizes compact SOT-723 surface-mount packaging for space-constrained layouts

Applications

• Automotive interface circuits requiring signal level shifting
