Overview
The KVX2201-23-0 is a silicon varactor diode manufactured by Microchip Technology, designed for surface-mount applications in the SOT-23-3 package. It features a single-diode configuration with a maximum peak reverse voltage of 22 V. Key electrical parameters include a capacitance of 50 pF at 0 V and 1 MHz, and a quality factor of 600 at 4 V and 50 MHz. The device operates within a temperature range of -55°C to 125°C.
Feature Summary
- High Q-factor performance suitable for RF tuning circuits
- Silicon construction for reliable variable capacitance control
- Compact SOT-23-3 surface-mount footprint
Applications
- RF filter tuning networks
- Voltage-controlled oscillator (VCO) circuits
- Phase-locked loop (PLL) frequency synthesis
Procurement Notes
Verify the specific suffix against official Microchip documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Ensure the ordering part number matches the required capacitance tolerance and reverse voltage ratings for the target application.
Selection Notes
Select this component when a high-Q varactor with 50 pF nominal capacitance is required in an SOT-23-3 package. Compare the 22 V reverse voltage rating against circuit operating conditions. Evaluate thermal management requirements given the -55°C to 125°C operating range. Verify compatibility with PCB layout constraints for the SOT-23-3 footprint.
Part Context
This part belongs to the KVX series of silicon varactor diodes from Microchip Technology. The series offers various capacitance values and configurations for RF applications. The KVX2201 variant specifically provides 50 pF capacitance, distinguishing it from other members like the KVX2001 or KVX2301 which offer different capacitance profiles.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Cross-reference with other Microchip KVX series parts only if electrical parameters match exactly.
