RF Diode Applications

• RF switching circuits
• Attenuator applications

RF Diode Procurement Notes

Verify the End of Life status before procurement planning, as this product is listed as discontinued or no longer manufactured. Confirm that the 5-TSOP package dimensions match the design footprint. Ensure compliance with RoHS3 and REACH requirements for the specific manufacturing batch. Check for available alternative packages within the BAP64 family if supply continuity is critical.

RF Diode Selection Notes

Select this component when a compact RF switch requires both CA and CC topologies in a small surface-mount form factor. The low capacitance value makes it suitable for high-frequency signal routing. Consider the thermal limits and power dissipation rating relative to the expected duty cycle in the target circuit design.

RF Diode Part Context

This part belongs to the BAP64 series of low capacitance PIN switching diodes. The BAP64Q variant specifically denotes the TSOP5 packaging option. Other variants in the series include different package types such as DFN1006D-2 and SOD323, offering flexibility for various board space constraints while maintaining similar electrical performance profiles.

RF Diode Replacement Considerations

Publicly confirmed substitute part numbers are not explicitly listed in the provided documentation. Designers should evaluate other BAP64 series members with compatible pinouts or seek equivalent RF PIN diodes from other manufacturers that meet the 100V reverse voltage and low capacitance specifications.
