RN2104,LXHF(CT

Overview

The RN2104,LXHF(CT is a PNP digital transistor manufactured by Toshiba Semiconductor and Storage, designed for automotive applications under the AEC-Q200 qualification standard. It integrates a single PNP bipolar junction transistor with internal biasing resistors in an SSM-3 (SOT-416) surface-mount package. Key electrical specifications include a collector-emitter voltage (VCEO) of -50 V and a continuous collector current (IC) of -100 mA. The device features a typical input base resistor (Q1BSR) of 22 kOhms and an emitter-base voltage (VEBO) of 10 V. It operates within a maximum junction temperature range up to +150 C and has a power dissipation rating of 100 mW.

Feature Summary

• Automotive-grade reliability certified to AEC-Q200 standards for robust performance in vehicle environments.
• Integrated biasing network simplifies circuit design by eliminating external resistor requirements.
• Compact SSM-3 surface-mount package facilitates high-density PCB layout.

Applications

• Automotive logic circuits and switching applications
• General-purpose signal switching in electronic control units
• Driver interface circuits for low-power loads

Procurement Notes

Verify the specific ordering suffix against official Toshiba documentation to confirm package type and tape-and-reel specifications. Ensure the component meets the required AEC-Q200 automotive qualification standards for the target application environment. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm availability and authenticity before procurement.

Selection Notes

Select this component when a PNP digital transistor with a 22 kOhm base resistor is required for automotive or industrial switching applications. Compare the -50 V voltage rating and -100 mA current capacity against circuit load requirements. Consider the SSM-3 package dimensions for board space constraints and verify thermal management needs against the 100 mW power dissipation limit.

Part Context

This part belongs to Toshiba's RN series of pre-biased transistors, which combine BJTs with internal resistor networks to reduce component count and assembly time. The LXHF suffix typically denotes specific packaging and automotive compliance variations within the broader RN product family. These devices are engineered to replace multiple discrete components, streamlining design processes for modern electronics.

Replacement Considerations

Direct substitutes must match the PNP polarity, -50 V VCEO, -100 mA IC, and 22 kOhm base resistance. Verify pinout compatibility with the SSM-3 package. Alternative parts from other manufacturers should be evaluated for equivalent AEC-Q200 certification if automotive use is intended.
