MV2105G

Overview

The MV2105G is a silicon tuning diode from the MMBV210xLT1 series, designed for high-volume FM radio and TV tuning applications. It provides solid-state reliability as a replacement for mechanical tuning methods. The device features a nominal capacitance of 15 pF at 4 Vdc reverse bias (1 MHz), with a range of 13.5 to 16.5 pF. It operates with a maximum reverse voltage of 30 Vdc and supports a forward current of 200 mAdc. The component is housed in a TO-92 package, suitable for through-hole mounting.

Feature Summary

• High Q figure of merit for efficient frequency control
• Controlled and uniform tuning ratio across operating range
• Standard capacitance tolerance of 10%
• Pb-free packaging available

Applications

• FM Radio tuning circuits
• TV tuning and AFC systems
• General frequency control applications

Procurement Notes

Verify the specific ordering suffix 'G' indicates Pb-free status per onsemi documentation. Confirm package type matches design requirements. Check RoHS compliance status directly from the manufacturer's datasheet or authorized distributor specifications before finalizing procurement decisions.

Selection Notes

Select this component when a nominal 15 pF variable capacitance is required for RF tuning. Ensure the application voltage does not exceed the 30 Vdc reverse limit. Consider the TO-92 package constraints for board layout. Verify thermal dissipation limits if operating near maximum junction temperatures.

Part Context

This part belongs to the MMBV210xLT1 series of Silicon Tuning Diodes. Other variants in the series include MV2101, MV2109, and LV2209, offering different capacitance ranges from 6.8 pF to 36.3 pF. All share similar electrical characteristics and package options, allowing for flexible design choices within the same family.

Replacement Considerations

Direct replacements include other MV2105 variants such as MV2105 without the G suffix, provided non-Pb-free materials are acceptable. Surface mount equivalents like MMBV2105LT1 offer identical electrical performance in SOT-23 packages.
