MV2101

Overview

The MV2101 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 general frequency control circuits. The device operates with a reverse voltage rating of 30 Vdc and a forward current capacity of 200 mAdc. At 25°C, the junction temperature reaches +150°C, while storage ranges from -55 to +150°C. Electrical characteristics at 25°C include a reverse breakdown voltage of 30 Vdc at 10 µA leakage, with maximum reverse leakage current of 0.1 µA at 25 Vdc. Diode capacitance measures between 6.1 pF (min) and 7.5 pF (max), typically 6.8 pF at 4.0 Vdc and 1.0 MHz. The figure of merit is typically 450 at 50 MHz, with a tuning ratio ranging from 2.5 to 3.2.

Procurement Notes

Verify the specific ordering suffix when purchasing. The 'G' suffix indicates a lead-free package compliant with RoHS standards. Confirm whether bulk or tape-and-reel shipping formats are required for the production line. Ensure the component matches the exact capacitance range specified for the target application design.

Selection Notes

Select the MV2101 based on the required capacitance value and reverse voltage ratings. Verify that the operating frequency aligns with the typical figure of merit specifications. Consider thermal derating requirements if ambient temperatures exceed 25 degrees Celsius. Confirm package compatibility with the intended PCB layout constraints.

Part Context

The MV2101 belongs to the MMBV2101LT1 series, which includes variants like the MV2105 and LV2209. These devices share similar design principles but differ in capacitance values and package types. The series is engineered to replace mechanical tuning components in consumer electronics, offering consistent performance across varying environmental conditions.

Replacement Considerations

The datasheet does not list specific public substitute part numbers. Designers should verify pinout compatibility and electrical parameter equivalence before replacing existing components in established designs.
