FJV3102RMTF

Overview

The FJV3102RMTF is an NPN pre-biased bipolar junction transistor manufactured by Fairchild Semiconductor. It integrates a single NPN silicon epitaxial transistor with two internal biasing resistors in a compact SOT-23-3 surface-mount package. The device features a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current (IC) of 100 mA. Typical integrated resistor values are 10 kΩ for both the base and emitter connections, resulting in a standard resistor ratio of 1. The component supports a maximum operating temperature of +150°C and is designed for low-power switching and logic interface applications.

Feature Summary

• Integrated dual-resistor network simplifies circuit design by eliminating external biasing components.
• Compact SOT-23-3 package enables high-density PCB layout and automated surface-mount assembly.
• High thermal stability allows reliable operation at elevated junction temperatures up to 150°C.

Applications

• Logic level shifting between microcontrollers and peripheral devices
• Low-power switching circuits in consumer electronics
• Driver stages for LED indicators or small loads

Procurement Notes

Verify the manufacturer origin, as Fairchild Semiconductor operations were integrated into ON Semiconductor. Confirm that the specific orderable part number matches the required resistor values and packaging format. Check for RoHS compliance status, as historical data indicates variations in environmental compliance across different production batches and legacy stock sources.

Selection Notes

Select this component when a fixed 10kΩ/10kΩ bias configuration is required for NPN switching. Ensure the 50V VCEO rating exceeds the maximum circuit voltage. Compare against variants like FJV3103RMTF if different resistor ratios are needed. Verify that the SOT-23-3 footprint aligns with the board design constraints and thermal requirements.

Part Context

This part belongs to the FJV series of pre-biased transistors from Fairchild Semiconductor. These devices combine discrete transistors with precision resistors to reduce component count. The series includes various resistor combinations tailored for specific logic families and drive requirements, offering a standardized solution for interface applications.

Replacement Considerations

Equivalent parts include the FJV3102RMTF_Q variant from Fairchild/ON Semiconductor. Cross-reference with other manufacturers' pre-biased NPN transistors featuring identical 10kΩ/10kΩ resistor networks and SOT-23-3 packaging to ensure pin compatibility and electrical parameter matching.
