MV104G

Overview

The MV104G is a silicon tuning diode featuring dual voltage variable capacitance diodes in a single TO-92 package. Designed for FM tuning and general frequency control, it utilizes a back-to-back configuration to minimize signal distortion and detuning. The device provides a guaranteed capacitance range of 37–42 pF at 3.0 Vdc reverse bias. It offers a high figure of merit (Q) of 140 typically at 100 MHz and ensures near-perfect matching between the two internal diodes with a maximum deviation of ±1.0% over the specified tuning range.

Feature Summary

Procurement Notes

Verify the specific ordering suffix G indicates a lead-free package compliant with current environmental standards. Confirm that the TO-92 bulk packaging aligns with your assembly requirements. Ensure the component meets the required operating temperature range and electrical characteristics for your specific design implementation before finalizing procurement.

Selection Notes

Select this component when space-saving dual-diode configurations are required for precise frequency tuning. The guaranteed capacitance tolerance and high Q factor make it suitable for sensitive RF applications. Verify that the TO-92 through-hole package fits your board layout constraints and that the reverse voltage ratings meet your circuit's operational limits.

Part Context

The MV104G belongs to onsemi's line of silicon tuning diodes designed for analog frequency control. It integrates two matched varactor diodes into one package to improve circuit symmetry. This integration reduces board space and cost while maintaining high performance in tuning applications where signal integrity is critical.

Replacement Considerations

Check datasheets for alternative dual tuning diodes offering similar capacitance ranges and Q factors. Ensure any substitute maintains the TO-92 footprint or verify pin compatibility if using an adapter. Confirm that the replacement part meets the same reverse voltage and power dissipation specifications.
