RF Diode Procurement Notes

Verify current availability status as the SMP1320 series has been subject to discontinuation notices. Confirm that the specific suffix indicates the correct SOT-23 package variant. Ensure compliance with RoHS directives if required for the target market. Check for valid EDA models for PCB layout integration. Validate lead-free soldering compatibility during assembly processes.

RF Diode Selection Notes

Select this component when low insertion loss and high isolation are critical in RF paths below 2 GHz. The SOT-23 package offers a balance between performance and board space. Consider the 0.4 nH inductance for high-speed switching requirements. Compare against other SMP1320 variants if different package sizes or electrical tolerances are needed for the specific application constraints.

RF Diode Part Context
