RF Diode Procurement Notes

Verify the specific suffix GM2/TR against official Microchip documentation to confirm package type and reel specifications. Ensure compatibility with RoHS3 standards if required by your manufacturing process. Cross-reference the DigiKey part number 150-MML4402-GM2/TR-ND for accurate distributor identification and datasheet access. Confirm lead times directly with authorized suppliers as production cycles may vary.

RF Diode Selection Notes

Select this component when a 75V reverse voltage rating is necessary for higher power handling compared to lower voltage alternatives. The 2-SMD package is ideal for surface mount assembly processes requiring compact footprints. Consider the 2pF capacitance specification for high-frequency applications where signal integrity is critical. Verify that the 1.5 ohm resistance at 100mA meets the insertion loss requirements of the target circuit design.

RF Diode Part Context

This device belongs to the MML4400 series of silicon PIN diodes designed for RF and microwave applications. The series offers various voltage ratings and package options to suit different system requirements.
