Overview
The KVX2152-23-0/TR is a single-path varactor diode manufactured by Microchip Technology, designed for surface-mount applications in the SOT-23-3 package. It features a maximum peak reverse voltage of 22 V and operates within a temperature range of -55°C to 125°C. Key electrical specifications include a capacitance of 1.3 pF at 20 V and 1 MHz, with a quality factor of 600 measured at 4 V and 50 MHz. The component is supplied in tape and reel packaging and complies with RoHS3 standards.
Feature Summary
- Single-channel varactor configuration optimized for compact surface-mount designs
- High Q-factor performance supporting efficient RF signal tuning
- Wide operating temperature range suitable for demanding environments
Applications
- RF circuit tuning and frequency control
- Voltage-controlled oscillator (VCO) implementations
- Phase-locked loop (PLL) filter networks
Procurement Notes
Verify the specific suffix against official documentation, as distribution records indicate this variant may be discontinued or replaced. Confirm current availability status directly with authorized channels before design finalization. Ensure the ordering part number matches the required packaging format to avoid supply chain discrepancies during procurement.
Selection Notes
Select this component when a low capacitance value near 1.3 pF is required at high reverse bias voltages. The high Q-factor makes it suitable for narrowband RF applications where signal loss must be minimized. Verify that the SOT-23-3 footprint aligns with the target PCB layout constraints and thermal management requirements.
Part Context
This device belongs to the KVX series of varactor diodes from Microchip Technology, which offers various capacitance ranges for different RF tuning needs. The KVX2152 specifically targets applications requiring lower capacitance values compared to higher-numbered variants in the same family, providing precise control in high-frequency circuits.
Replacement Considerations
DigiKey records indicate the KVX2152-23-0 bulk version is no longer sold. Check for direct replacements within the KVX series or consult Microchip for updated equivalent part numbers that maintain the same electrical characteristics and package dimensions.
