RF Diode Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and marking codes. Confirm RoHS compliance status via the official Certificate of Conformance prior to procurement. Ensure handling procedures adhere to industry-standard ESD precautions during storage and assembly.

RF Diode Selection Notes

Select this component when a low-inductance SC-70 package is required for space-constrained designs. Evaluate the 0.75 Ω typical resistance and 0.23 pF typical capacitance against switch isolation requirements. Verify that the 400 mW power dissipation rating aligns with thermal management capabilities in the target application environment.
