RN2305,LXHF

Overview

The RN2305,LXHF is a single PNP digital transistor (BRT) manufactured by Toshiba Semiconductor and Storage. It integrates a monolithic NPN transistor with internal biasing resistors in an SC-70-3 package. Key electrical parameters include a maximum collector-emitter 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 base resistor (R1) of 47 kOhms and an emitter resistor (R2) of 22 kOhms. It meets AEC-Q101 automotive qualification standards and operates within a temperature range of -55°C to +150°C.

Feature Summary

• Integrated biasing network simplifies circuit design by reducing external component count.
• Automotive-grade reliability certified under AEC-Q101 standards for harsh environments.
• Compact surface-mount packaging facilitates high-density PCB layouts.

Applications

• Automotive logic level shifting and switching circuits
• General-purpose digital switching applications
• Interface circuits between microcontrollers and peripheral devices

Procurement Notes

Verify the specific ordering code suffix against the manufacturer's latest datasheet to ensure correct resistance values and package type. Confirm AEC-Q101 compliance requirements if deploying in automotive systems. Check for RoHS directive adherence prior to integration into regulated assemblies.

Selection Notes

Select this component when a single PNP switch with integrated biasing is required. Ensure the -50 V rating exceeds the maximum circuit voltage. Verify that the 47 kOhm base resistor value provides adequate drive current for the intended load without exceeding the -100 mA collector current limit.

Part Context

This part belongs to Toshiba's RN series of pre-biased transistors. These devices combine bipolar junction transistors with built-in bias resistors to replace multiple discrete components. The RN2305 variant specifically offers a single PNP configuration optimized for space-constrained designs requiring reliable switching performance.

Replacement Considerations

Consult official cross-reference lists for direct substitutes. Alternative parts must match the PNP polarity, -50 V VCEO rating, -100 mA IC limit, and SC-70-3 footprint. Verify equivalent resistance ratios and thermal characteristics before substitution.
