RN2115,LXHF(CT

Overview

The RN2115,LXHF(CT is a single PNP digital transistor manufactured by Toshiba Semiconductor and Storage, designed for surface-mount applications. It integrates a bias resistor network within a compact SSM-3 (SOT-416) package to simplify circuit design. The device features a collector-emitter voltage of -50 V and a continuous collector current of -100 mA. Key electrical parameters include a typical base resistance of 47 kOhms and an emitter-base voltage of 10 V. It operates with a maximum power dissipation of 100 mW and supports junction temperatures up to +150 C. The component is qualified under AEC-Q200 standards for automotive reliability.

• Driver circuits for low-power loads

Procurement Notes

Verify the specific suffix LXHF(CT against the official Toshiba datasheet to confirm packaging type and tape-and-reel specifications. Ensure the ordering part number matches the required AEC-Q200 qualification level for your target application. Cross-reference the manufacturer's latest documentation to confirm RoHS compliance status and any changes in pin configuration or thermal characteristics before finalizing procurement.

Selection Notes

Select this component when a single PNP digital transistor with high input impedance is required. The 47 kOhm base resistor makes it suitable for direct interfacing with logic outputs that require minimal drive current. Consider the SSM-3 package size for space-constrained designs. Verify that the -50 V rating meets the system's voltage requirements and that the 100 mA current capacity is sufficient for the intended load switching application.

Part Context

This component belongs to Toshiba's RN series of pre-biased transistors, which combine bipolar junction transistors with internal bias resistors. The RN2115 variant specifically provides a PNP configuration optimized for automotive and industrial applications. It complements other devices in the family, such as the RN2114 and RN2116, offering different resistor ratios for varied logic interface needs while maintaining consistent package and performance characteristics.

Replacement Considerations

Check for direct substitutes like the RN2114 or RN2116 if resistor values differ from design requirements. Verify pinout compatibility with the SSM-3 package before replacing. Ensure any alternative maintains AEC-Q200 certification if used in automotive contexts. Confirm that the replacement's VCEO and IC ratings meet or exceed the original specifications.
