KV1401-17

Overview

The KV1401-17 is a single-element variable capacitance diode manufactured by Microsemi, now part of Microchip Technology. Designed for very high frequency applications, this silicon-based component features a nominal diode capacitance of 81.5 pF with a tight tolerance of 5%. It exhibits a minimum breakdown voltage of 12 V and achieves a minimum capacitance ratio of 12. The device is housed in a ceramic, metal-sealed cofired square microwave package with two terminals, ensuring compliance with RoHS standards.

Feature Summary

• Utilizes silicon material for reliable variable capacitance performance in very high frequency circuits.
• Encapsulated in a ceramic, metal-sealed cofired package designed specifically for microwave applications.
• Provides precise capacitance control with a 5% tolerance on the nominal 81.5 pF rating.

Applications

• Very high frequency tuning circuits
• Microwave varactor applications
• RF phase shifters

Procurement Notes

Verify the manufacturer lineage, as Microsemi was acquired by Microchip Technology. Confirm that the specific ordering suffix corresponds to the standard ceramic metal-sealed cofired package. Ensure the component meets current RoHS compliance requirements for your assembly process. Cross-reference the ECCN code EAR99 with export regulations applicable to your region before finalizing procurement.

Selection Notes

Select this component when a fixed 81.5 pF nominal capacitance with 5% tolerance is required for VHF or microwave designs. The 12 V minimum breakdown voltage limits its use in high-voltage reverse bias scenarios. The ceramic metal-sealed package offers environmental protection suitable for demanding microwave environments but requires appropriate surface mount handling techniques.

Part Context

This component belongs to the family of discrete semiconductor diodes, specifically categorized under variable capacitance devices. It serves as a passive RF element within larger electronic systems, distinct from active integrated circuits like microcontrollers. Its primary function relies on the voltage-dependent capacitance property of the PN junction in silicon.

Replacement Considerations

Direct substitutes must match the 81.5 pF nominal capacitance, 5% tolerance, and 12 V breakdown voltage. Verify that alternative packages are compatible with the ceramic metal-sealed cofired form factor. Check if other manufacturers offer equivalent microwave varactors with identical JESD-30 codes and terminal configurations.
