RF Diode Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation. Check for end-of-life notifications or product change notices that may affect long-term availability. Ensure the specific suffix matches design requirements before procurement.

RF Diode Selection Notes

Select this component when a compact quad PIN diode structure is required for high-frequency RF applications. Consider the 220 fF capacitance and 1.5 Ohm series resistance limits for impedance matching. Verify that the SOT-25 package fits the board layout constraints and that the 50 V reverse voltage rating exceeds circuit peak voltages.
