RF Diode Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging configuration. The BLKG suffix indicates bulk packaging containing 100 pieces per antistatic bag. Confirm that the required quantity aligns with this unit count rather than reel-based options. Ensure the component meets lead-free requirements if applicable to the assembly process.

RF Diode Selection Notes

Select this component when ultra-low resistance is critical for switching performance. The single diode configuration suits simple SPST or basic attenuator topologies. Verify that the 50 V breakdown rating accommodates the peak inverse voltage in the target circuit. Consider the SOT-23 footprint constraints during PCB layout design.
