RF Diode Procurement Notes

Verify the specific ordering suffix when purchasing. The 'G' suffix indicates a Pb-free package configuration. Confirm tape and reel specifications, including part orientation and tape sizes, by referencing the manufacturer's Tape and Reel Packaging Specifications brochure (BRD8011/D) prior to procurement to ensure compatibility with assembly equipment.

RF Diode Selection Notes

Select this component for designs requiring low capacitance and low series resistance in the VHF range. Ensure the operating junction temperature remains within the +125 °C limit and that power dissipation does not exceed 200 mW at 25°C ambient temperature. Derate power dissipation by 2.0 mW/°C for temperatures above 25°C to maintain device integrity.
