Feature Summary

• Dual common cathode configuration for compact circuit design
• Capacitance variation enabled by reverse voltage adjustment
• Optimized for radio frequency signal tuning

Applications

• RF oscillator circuits
• Voltage-controlled filter designs
• Frequency modulation systems

Procurement Notes

Verify the specific datasheet version to confirm electrical tolerances and thermal characteristics before integration. Ensure the PCB footprint matches the MCPH package dimensions precisely. Check for end-of-life status as availability may be restricted. Confirm that the operating voltage range aligns with system requirements to prevent breakdown. Validate supplier authenticity through authorized channels only.

Selection Notes

Select this component when a dual varactor structure is required for balanced RF tuning or differential signal paths. Consider the 16V reverse voltage limit and the 44.91pF maximum capacitance against circuit needs. Evaluate the capacitance ratio of 2.3 for tuning linearity requirements. Compare against single varactor options if space constraints are less critical. Ensure compatibility with the target frequency range of operation.

Part Context

This part belongs to the varactor diode category within onsemi's discrete semiconductor portfolio. Varactors are essential for voltage-dependent capacitance applications. The dual common cathode variant allows for more complex tuning networks compared to single units. It supports high-frequency analog circuit designs where electronic tuning is preferred over mechanical adjustments.
