Overview
The onsemi 2N5639RLRAG is an N-channel Junction Field-Effect Transistor (JFET) housed in a TO-92 surface-mount package. It features a maximum drain-source voltage of 30V and a continuous drain current rating of 50mA. The device exhibits a maximum gate-source cutoff voltage of -1.0V and a typical forward transadmittance of 4000 µS at VDS = 10V and f = 1kHz. Operating characteristics include a maximum feedback capacitance of 4pF and a maximum gate reverse current of 1nA at VGS = -20V. The component supports a junction temperature range from -55°C to +150°C.
Feature Summary
- Utilizes JFET technology for high input impedance applications
- Designed for low-noise signal amplification and switching
- Compatible with standard TO-92 surface-mount footprints
Applications
- Low-noise preamplifier stages
- High-impedance buffer circuits
- Analog switching matrices
Procurement Notes
Verify the specific suffix RLRAG against the manufacturer's official datasheet to confirm package type, lead finish, and tape-and-reel specifications. Ensure the ordering part number matches the exact electrical tolerances required for the design. Cross-reference the RoHS compliance status and lead-free designation with current regulatory documentation before finalizing procurement orders.
Selection Notes
Select this component when a compact N-channel JFET is required for low-voltage analog signal paths. Compare the 30V breakdown and 50mA current limits against circuit requirements. Evaluate the 4000 µS transadmittance for gain needs. Consider the TO-92 SMD form factor for space-constrained PCB layouts where through-hole alternatives are unsuitable.
Part Context
This part belongs to the 2N5639 family of N-channel JFETs manufactured by onsemi. The base 2N5639 designation defines the core semiconductor structure and electrical performance profile. The RLRAG suffix indicates specific packaging and handling attributes, distinguishing it from other variants like the through-hole 2N5639 or different reel configurations within the same product line.
Replacement Considerations
Publicly confirmed substitute part numbers for the 2N5639RLRAG are not available in the provided reference data. Verify compatibility with generic 2N5639 equivalents only if pinout and electrical parameters match exactly.
