RF Diode Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific -BLKG suffix indicates bulk packaging containing 100 pieces per antistatic bag. Ensure compliance with RoHS directives and check for any relevant Product Change Notices (PCN) prior to procurement.

RF Diode Selection Notes

Select this component when a Series PIN diode configuration is required for low distortion applications. The SOT-323 package suits space-constrained designs. Verify that the 100 V breakdown voltage and 0.35 pF capacitance meet the circuit's isolation and impedance requirements. Consider the 1500 ns carrier lifetime for appropriate switching speed needs.

RF Diode Part Context

This part belongs to the HSMP-381x family of surface mount RF PIN diodes manufactured by Broadcom Limited. The series includes various configurations such as Single, Common Anode, Common Cathode, and Reverse Series. The HSMP-3812 specifically denotes the Series lead code configuration within this lineup.

RF Diode Replacement Considerations
