Overview
The MV2109 is a silicon tuning diode designed for high-volume FM radio and TV tuning applications. It provides solid-state reliability as a replacement for mechanical tuning methods in AFC and frequency control circuits. The device operates with a maximum reverse voltage of 30 Vdc and supports a forward current of 200 mAdc. It features a standard capacitance tolerance of 10% and offers controlled, uniform tuning ratios. Available in TO-92 packages, it ensures stable performance across varying temperatures.
Feature Summary
- High Q factor for improved circuit efficiency
- Controlled and uniform tuning ratio characteristics
- Standard 10% capacitance tolerance
- Lead-free package options available
Applications
- FM Radio tuning circuits
- TV tuning and AFC systems
- General frequency control applications
Procurement Notes
Verify the specific ordering suffix to confirm package type and environmental compliance. The 'G' suffix indicates a lead-free package variant. Confirm availability status as some variants may be discontinued or subject to manufacturing changes. Ensure the selected part matches the required capacitance range and package style for the target design.
Selection Notes
Select the MV2109 when a 30V reverse voltage rating and approximately 33 pF nominal capacitance are required. Consider the TO-92 through-hole package for standard assembly processes. Evaluate the Q factor at 50 MHz and the tuning ratio requirements against the application's frequency stability needs before finalizing the component choice.
Part Context
The MV2109 belongs to the MMBV2101LT1 series of silicon tuning diodes from onsemi. This family includes various capacitance values ranging from 6.8 pF to 100 pF, all sharing similar electrical characteristics and package options. The series is specifically engineered to replace mechanical tuning components in consumer electronics.
Replacement Considerations
Direct replacements within the same series include MMBV2109LT1 (SOT-23) and LV2209 (TO-92). Verify pinout compatibility and capacitance tolerances when substituting with other models in the MMBV210x series.
FAQ
What is the typical capacitance value of the MV2109?
The typical capacitance value is 33 pF, with a minimum of 29.7 pF and a maximum of 36.3 pF.
What is the maximum reverse voltage rating?
The maximum reverse voltage (VR) rating is 30 Vdc.
How is the tuning ratio defined for this device?
