RF Diode Procurement Notes
Verify the specific ordering suffix against official Skyworks documentation to confirm package type and marking. Confirm lead-free status and RoHS compliance requirements prior to procurement. Ensure ESD precautions are implemented during handling as the device is classified as Class 1B. Check for any discontinuation notices or product changes before finalizing orders.
RF Diode Selection Notes
Select this component for designs requiring fast RF switching speeds due to its short carrier lifetime. The SC-70 Green package offers a compact footprint suitable for space-constrained PCB layouts. Verify that the 1.4 nH inductance aligns with the impedance matching network requirements for the target frequency band up to 6 GHz.
RF Diode Part Context
This part belongs to the SMP1345 series of very low capacitance plastic packaged silicon PIN diodes. The series includes various configurations such as common anode, common cathode, single ring, and single packages. The SMP1345-075LF specifically denotes the SC-70 Green package variant within this family.
