RN2309,LXHF

Overview

The RN2309,LXHF is a single PNP digital transistor from Toshiba Semiconductor and Storage, designed for automotive applications under AEC-Q101 standards. It integrates a built-in bias resistor network with typical values of 47 kOhms (R1) and 22 kOhms (R2), yielding a ratio of 2.14. The device operates with a maximum collector-emitter voltage (VCEO) of -50 V and a continuous collector current (IC) of -0.1 A. Key electrical parameters include a minimum DC current gain (hFE) of 70 and a maximum operating frequency ranging from 200 MHz to 250 MHz. Packaged in an SOT-323 (SC-70-3) surface-mount format, it dissipates up to 100 mW.

Feature Summary

• Automotive-grade reliability certified by AEC-Q101 qualification standards
• Integrated dual-resistor network simplifies circuit design and reduces component count
• High-speed switching capability suitable for frequencies up to 250 MHz
• Compact SMD package optimized for high-density PCB layouts

Applications

• Automotive logic level shifting and signal switching
• General-purpose digital switching in consumer electronics
• Interface circuits requiring pre-biased transistor arrays

Procurement Notes

Verify the specific suffix LXHF against official Toshiba documentation to confirm packaging type and compliance status. Confirm AEC-Q101 automotive qualification requirements match your system specifications. Ensure the SOT-323 footprint aligns with your PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when a single PNP digital switch with integrated biasing is required for automotive or high-reliability applications. Compare the 47k/22k resistor configuration against alternative models if different input impedance characteristics are needed. Verify that the -50V voltage rating and -100mA current capacity meet the load requirements of the target circuit application.

Part Context

This part belongs to the Toshiba RN series of pre-biased transistors, which combine bipolar junction transistors with internal resistors. The RN2309 variant specifically provides a PNP configuration in a compact SOT-323 package. The LXHF suffix typically denotes tape-and-reel packaging for automated assembly processes.

Replacement Considerations

Direct substitutes within the same family include other RN2xxx PNP variants with similar resistor ratios. Cross-reference the SOT-323 pinout and electrical limits with competitors like ROHM or ON Semiconductor if sourcing alternatives are necessary.
