RN2301,LXHF

Overview

The RN2301,LXHF is a PNP Bias Resistor Built-in Transistor (BRT) manufactured by Toshiba Semiconductor and Storage. It integrates a single PNP bipolar junction transistor with two internal bias resistors, specified as 4.7 kOhms base resistor and 4.7 kOhms emitter resistor. The device features a maximum collector-emitter voltage of -50 V and a continuous collector current of -100 mA. It operates within a temperature range up to +150 C and is housed in an SMD/SMT SC-70-3 package. The component meets AEC-Q101 automotive qualification standards.

Feature Summary

• Integrates a PNP transistor with dual internal bias resistors for simplified circuit design
• Automotive-grade reliability compliant with AEC-Q101 qualification standards
• High thermal stability supporting operation at temperatures up to +150 C
• Compact surface-mount packaging suitable for space-constrained applications

Applications

• Automotive electronic control unit input/output interfacing
• General-purpose switching circuits in automotive systems
• Logic level translation and buffer stages in vehicle electronics
• Pre-biased switching applications requiring minimal external components

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the requested part number matches the exact electrical parameters and package type required for the target application. Cross-reference the AEC-Q101 certification status if automotive compliance is mandatory for the end product.

Selection Notes

Select this component when a PNP digital transistor with equal 4.7 kOhm bias resistors is required. Ensure the system voltage does not exceed the -50 V collector-emitter rating. Consider the -100 mA current limit for load driving capabilities. Verify compatibility with the SC-70-3 footprint during PCB layout design.

Part Context

This component belongs to Toshiba's RN series of Bias Resistor Built-in Transistors. These devices combine transistors and resistors into a single package to reduce board space and assembly costs. The LXHF suffix typically indicates specific packaging or environmental compliance attributes defined by the manufacturer.

Replacement Considerations

Consult official cross-reference lists for direct substitutes. Equivalent parts must match the PNP polarity, -50 V rating, -100 mA current, and 4.7k/4.7k resistor configuration.
