Procurement Notes

Verify the specific part number against official manufacturer documentation to ensure accuracy, as datasheet availability may vary across distributor platforms. Confirm that the SOT-23 package dimensions and electrical ratings match the design requirements before integration. Cross-reference the manufacturing date code and compliance status with current supply chain records to avoid obsolete or non-compliant stock.

Selection Notes

Select this component when a single varactor diode with a 30 V reverse voltage rating and 20 pF minimum capacitance is required. Ensure the application demands a tuning ratio of at least 4.5 between 3 V and 25 V bias voltages. Verify that the operating environment stays within the specified -55 °C to +125 °C temperature range and that the SOT-23 package fits the PCB layout constraints.

Part Context

This component belongs to the varactor diode category from onsemi, specifically engineered for RF and microwave tuning applications. It shares the SOT-23 form factor common in low-power signal processing components. The device complements other frequency-control elements by providing variable capacitance characteristics essential for precise oscillator stabilization and channel selection in communication systems.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with alternative varactor diodes by matching key parameters such as reverse voltage, capacitance range, and package type through official manufacturer cross-reference tools.
