Overview
The MPV1965-206 is a silicon varactor diode manufactured by Microchip Technology. It is housed in an MMSM surface-mount package and is classified as non-hermetic. The component functions as a voltage-variable capacitor, where the junction capacitance changes with applied reverse bias voltage. This characteristic allows it to be used in tuning circuits for radio frequency applications. The device is part of the MPV series of varactor diodes designed for compact electronic designs requiring precise capacitance control.
Feature Summary
- Voltage-dependent capacitance variation for circuit tuning
- Surface-mount MMSM package for automated assembly
- Silicon construction for reliable RF performance
Applications
- RF oscillator tuning circuits
- Voltage-controlled oscillators (VCOs)
- Frequency synthesizers
Procurement Notes
Verify the specific suffix code against the manufacturer's official datasheet to confirm exact electrical parameters and packaging details. Ensure the component meets RoHS compliance requirements if mandated by the design specifications. Confirm availability status directly with authorized distributors as stock levels fluctuate.
Selection Notes
Select this component based on required capacitance range and Q-factor at the target operating frequency. Compare the MMSM package dimensions against PCB layout constraints. Evaluate thermal management needs and ensure the reverse breakdown voltage exceeds the maximum expected circuit voltage.
Part Context
This part belongs to the Microchip MPV series of silicon varactor diodes. These components are engineered for high-reliability applications in communication systems. The series offers various capacitance ratios and voltage coefficients to suit different tuning requirements across RF and microwave frequencies.
Replacement Considerations
Check for direct cross-reference numbers provided in Microchip documentation. Verify that any substitute maintains identical pinout, package type, and critical electrical characteristics such as Cj and Cv ratio.
