FJV3103RMTF

Overview

The FJV3103RMTF is an NPN digital transistor from the FJV3103R series, manufactured by onsemi following its acquisition of Fairchild Semiconductor. It features a single configuration in an SOT-23-3 surface-mount package. Key electrical parameters include a collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. The device incorporates a typical input resistor of 22 kOhms with a typical resistor ratio of 1. It offers a minimum DC current gain (hfe) of 56 and operates within a temperature range of -55°C to +150°C, with a power dissipation rating of 200 mW.

Feature Summary

• Integrated pre-biased design combining an NPN transistor with internal base resistors for simplified circuit implementation.
• High thermal stability supporting operation up to +150°C junction temperature.
• Compact SOT-23-3 packaging suitable for space-constrained surface-mount applications.

Applications

• General-purpose switching circuits requiring integrated biasing.
• Driver stages for low-current loads in consumer electronics.
• Logic level translation interfaces in embedded systems.

Procurement Notes

Verify component authenticity through authorized distribution channels due to potential obsolescence status. Confirm that the part number suffix corresponds to the specific manufacturing origin and compliance requirements. Review the latest datasheet for any changes resulting from the Fairchild-onsemi integration. Ensure storage conditions meet moisture sensitivity level specifications prior to assembly.

Selection Notes

Select this component when a single NPN digital transistor with a 22 kOhm base resistor is required. Compare against alternatives if different resistance values or higher current ratings are needed. Verify that the 50 V voltage rating and 100 mA current capacity align with the target application's electrical constraints. Consider the SOT-23-3 footprint compatibility during PCB layout design.

Part Context

This component belongs to the FJV3103R family of pre-biased bipolar transistors originally developed by Fairchild Semiconductor. Following the corporate merger, production and documentation were transitioned to onsemi. The part represents a standard discrete solution for integrating transistor switching functionality with built-in biasing networks, reducing external component count in digital logic interfaces.

Replacement Considerations
