Overview
The KVX31S1-23-0/TR is a single silicon hyper-abrupt varactor diode manufactured by Microchip Technology. It is housed in a surface-mount SOT-23-3 package and features non-hermetic plastic construction. The device is rated for a maximum peak reverse voltage of 27V. This component is designed for applications requiring precise control of voltage and current, serving as a variable capacitance element in electronic circuits.
Feature Summary
- Utilizes silicon technology for hyper-abrupt capacitance-voltage characteristics
- Designed for surface-mount assembly in compact electronic systems
- Provides variable capacitance functionality for circuit tuning
Applications
- Industrial applications requiring precise voltage and current control
- RF circuit tuning and frequency adjustment
- Voltage-controlled oscillator (VCO) implementations
Procurement Notes
Verify the specific suffix designation when ordering, as availability may vary between standard tape-and-reel packaging and quote-only configurations. Confirm that the selected variant matches the required package type and voltage rating for the target application design. Ensure compliance with all specified electrical limits during integration.
Selection Notes
Select this component for designs necessitating a small-form-factor variable capacitor with defined reverse voltage limits. The SOT-23-3 package facilitates automated placement in space-constrained layouts. Evaluate the hyper-abrupt characteristic requirements against alternative linear or step-varactor options to ensure optimal circuit performance.
Part Context
This part belongs to the family of silicon variable capacitance diodes offered by Microchip Technology. These components are distinct from fixed capacitors and other semiconductor devices, specifically engineered to provide tunable reactance. The product line supports various packaging options to accommodate different manufacturing and spatial requirements.
Replacement Considerations
Direct substitutes include the KVX31S1-23-0 variant, which shares identical electrical specifications and physical dimensions. When replacing, ensure the new unit maintains the same SOT-23-3 footprint and 27V peak reverse voltage rating to preserve circuit integrity.
