RF Diode Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific tape and reel options if automated placement is required. Ensure storage conditions remain within specified limits to maintain reliability before soldering.

RF Diode Selection Notes

Select this part when guaranteed performance specifications are critical rather than typical values found in other series. Consider the 200 V breakdown voltage for high-voltage switching needs. Evaluate the 1.5 Ω series resistance against circuit loss requirements. Verify that the SOT-23 package dimensions fit the PCB layout constraints.
