RF Diode Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details. The BLKG suffix corresponds to units supplied in anti-static bags. Confirm availability status as components may be subject to obsolescence notices or limited supply conditions from the manufacturer.

RF Diode Selection Notes

Select this component for designs requiring low distortion attenuation in microwave frequencies. Ensure the SOD-323 package dimensions fit the board space constraints. Verify that the 100 V breakdown voltage and 0.35 pF capacitance meet the circuit requirements for the intended operating frequency range.

RF Diode Part Context

The HSMP-381Z is part of Broadcom's portfolio of RF PIN diodes designed for attenuator applications. It serves as a transition option for customers previously using larger packages like SOT-23 and SOT-323, offering a smaller outline to accommodate end product designs with limited board space while maintaining performance.
