2N5638RLRAG

Overview

The onsemi 2N5638RLRAG is an N-channel Junction Field-Effect Transistor (JFET) designed for chopper applications. It features a Drain-to-Source Voltage (Vdss) of 30V and operates in the TO-92 package. Key electrical parameters include an Input Capacitance (Ciss) of 10pF at Vds, a maximum power dissipation of 310 mW, and a Drain Current (Idss) of 50 mA @ 20 V with Vgs=0. The device exhibits an RDS(On) resistance of 30 Ohms.

Feature Summary

• N-channel depletion mode JFET configuration
• Optimized for chopper transistor applications
• Low input capacitance for signal integrity

Applications

• Chopper circuits
• Small signal amplification
• Analog switching

Procurement Notes

Verify the specific suffix 'RLRAG' against the manufacturer's current datasheet to confirm tape and reel specifications and environmental compliance status. Ensure the TO-92 package orientation matches the design requirements. Cross-reference the part number with official onsemi documentation to validate availability and lead times through authorized distributors.

Selection Notes

Select this component when an N-channel JFET with low input capacitance is required for chopper or small-signal applications. Consider the 30V Vdss limit and 310 mW power dissipation constraints. Verify that the TO-92 through-hole package fits the PCB layout. Compare Idss and RDS(On) values against circuit requirements to ensure proper biasing and performance.

Part Context

This part belongs to the 2N5638 family of JFETs from onsemi. It is a silicon-based small-signal junction field-effect transistor. The RL suffix typically indicates tape and reel packaging, while RAG may denote specific environmental or manufacturing codes. It is distinct from other variants in the series by its specific packaging and potential minor parameter tolerances defined by the manufacturer.

Replacement Considerations

Direct substitutes include other 2N5638 variants from different manufacturers, provided they match the N-channel, 30V Vdss, and TO-92 package specifications. Verify pinout compatibility and electrical parameters such as Idss and RDS(On) before substitution.
