Overview
The UMX9989SM/TR is a PIN diode manufactured by Microchip Technology. It utilizes silicon technology and is housed in a hermetic MELF package. The component is classified under PIN Diodes within the Diodes & Rectifiers subcategory. RoHS compliance is indicated as non-compliant (N). The unit weight is specified at 294.174 mg. Availability is restricted, with current supply status indicating limited sales or factory special orders.
Feature Summary
- Hermetic sealing for environmental protection
- Silicon PIN diode construction
- MELF package form factor
Applications
- RF switching applications
- Attenuator circuits
- High-frequency signal processing
Procurement Notes
Verify availability directly with Microchip Technology due to restricted supply status. Confirm RoHS non-compliance requirements for your specific application environment. Ensure the hermetic MELF package meets your assembly and reliability standards before finalizing procurement plans.
Selection Notes
Select this component when hermetic sealing is required for silicon PIN diodes in RF applications. Compare against non-hermetic plastic SMT alternatives like the UMX9989-GM2 if environmental sealing is not critical. Verify package compatibility with existing PCB footprints and thermal management strategies.
Part Context
This part belongs to Microchip's silicon PIN diode portfolio. It shares the core device structure with the UMX9989-GM2 but differs in packaging. The hermetic MELF variant offers distinct environmental robustness compared to standard plastic surface-mount options within the same product family.
Replacement Considerations
The UMX9989-GM2 serves as a non-hermetic alternative. Verify package dimensions and sealing requirements before substitution. No other direct public substitutes are confirmed.
