FJV3101RMTF

Overview

The FJV3101RMTF is a digital transistor manufactured by onsemi, belonging to the FJV3101R series. It is an NPN configuration device housed in a surface-mount SOT-23-3 package. The component integrates internal biasing resistors to simplify circuit design. Key electrical specifications include a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current rating of 100 mA. The typical input resistance is specified at 10 kOhms with a resistor ratio of 0.47. The device supports a wide operating temperature range from -55°C to +150°C and has a power dissipation capability of 200 mW.

Feature Summary

• Integrated biasing network reduces external component count
• High thermal stability with extended temperature range
• Compact surface-mount packaging for space-constrained designs

Applications

• General-purpose switching applications
• Driver circuits for low-power loads
• Logic level translation interfaces

Procurement Notes

Verify end-of-life status before procurement as the component may be obsolete. Confirm RoHS compliance details through official datasheets. Ensure supply chain sources provide valid traceability documentation. Check for alternative packages if lead times are critical. Validate that the specific suffix matches required manufacturing standards.

Selection Notes

Select this part for single NPN digital transistor needs requiring 50V blocking capability. Compare input resistance values against other series variants like FJV3103R for different base drive requirements. Consider the SOT-23-3 footprint compatibility during PCB layout. Evaluate thermal management needs given the 200 mW dissipation limit in enclosed environments.

Part Context

This component is part of onsemi's broader portfolio of pre-biased bipolar transistors. It shares the FJV310x family characteristics but differs in internal resistor values compared to siblings like FJV3103R. The product line targets cost-sensitive consumer and industrial electronics where simplified driver stages are preferred over discrete resistor networks.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify pinout compatibility and electrical ratings when considering generic equivalents. Cross-reference with Fairchild Semiconductor legacy data if sourcing from older inventory channels.
