KVX3201-23-0

Overview

The KVX3201-23-0 is a surface mount hyperabrupt varactor diode from the KVX2001–KVX3901A series, manufactured by Microchip Technology. It utilizes silicon mesa geometry and high-energy ion implantation to deliver high Q factors and wide tuning ratios within an SOT-23 package. The device features a minimum breakdown voltage of 27V at 10uA leakage current. Capacitance ranges from 9.5pF to 14.5pF at 0V reverse bias, dropping to 1.8pF–2.8pF at 20V reverse bias. It maintains a minimum quality factor of 750 at 4V reverse bias and 50MHz. Operating temperatures span from -55°C to +125°C.

Feature Summary

• High ratio hyperabrupt capacitance-voltage characteristics for wide bandwidth linear tuning
• Silicon mesa geometry with dense SiO2 passivation for high reliability
• Excellent wide band linearity suitable for low phase noise applications

Applications

• Wide bandwidth linear VCOs from VHF through 1500 MHz
• PLL VCOs requiring octave bandwidth
• Voltage variable filters (VVFs)
• Phase shifters demanding lower distortion

Procurement Notes

Verify component authenticity through authorized Microchip distributors or direct channels. Confirm RoHS compliance status and termination finish details prior to assembly. Ensure ESD handling protocols are strictly followed during storage and installation. Validate datasheet revisions against specific manufacturing lot requirements.

Selection Notes

Select this component when high Q factors and wide tuning ratios are required in compact surface mount designs. The 27V breakdown rating supports higher peak voltage handling compared to 22V variants. Verify that the SOT-23 package dimensions align with PCB layout constraints. Consider back-to-back configurations if enhanced voltage handling is necessary.

Part Context

This part belongs to the KVX2001–KVX3901A family of microwave hyperabrupt varactors. These devices share common packaging and fabrication technologies but differ in capacitance values and breakdown voltages. The KVX3xxx series specifically offers 27V ratings, distinguishing it from the 22V KVX2xxx series within the same product line.

Replacement Considerations

Direct substitutes include other KVX3xxx series parts such as KVX3201A or KVX3901A, provided capacitance and Q factor tolerances match design requirements. Cross-referencing electrical parameters with the official configuration sheet is essential before substitution.
