Procurement Notes

Verify the specific ordering suffix LT1G against current manufacturer documentation to ensure correct tape-and-reel specifications. Confirm RoHS compliance status through official onsemi material declarations prior to integration. Cross-reference the full part number with authorized distributors to validate current availability and prevent procurement of obsolete or non-compliant variants.

Selection Notes

Select this component when a minimum capacitance of 20pF and a 30V reverse voltage rating are required for tuning applications. Ensure the design accommodates the specified 3V to 25V tuning range to achieve the documented minimum tuning ratio of 4.5. Verify that the SOT-23 package dimensions fit the available PCB footprint and that the thermal environment remains within the +125°C maximum operating temperature limit.

Part Context

This varactor diode belongs to the MMBV series from onsemi, which focuses on small-signal tuning components. It serves as a specialized semiconductor device distinct from general-purpose rectifiers or Zener diodes. The component is engineered specifically for variable capacitance functions in RF and microwave circuits rather than power handling or signal rectification tasks.

Replacement Considerations
