Overview
The UMX9989SM is a PIN diode manufactured by Microchip Technology, utilizing silicon technology. It is housed in a hermetic MELF package and classified under the PIN Diodes product category within the Diodes & Rectifiers sub-category. The component has an approximate unit weight of 294.174 mg. According to available distributor records, this specific part number is currently not supplied by Mouser, indicating limited availability or special order status.
Feature Summary
- Hermetic sealing for environmental protection
- Silicon-based PIN diode construction
- MELF package form factor
Applications
- RF switching applications
- Attenuator circuits
- High-frequency signal processing
Procurement Notes
Verify current supply status directly with Microchip Technology or authorized distributors, as the UMX9989SM is listed as unavailable through major retailers like Mouser. Confirm if the part is restricted to factory special orders or discontinued. Request official documentation to ensure compliance with RoHS standards and verify the exact package specifications before procurement planning.
Selection Notes
Select the UMX9989SM when a hermetically sealed silicon PIN diode in a MELF package is required. Compare against the non-hermetic UMX9989-GM2 variant if plastic SMT packaging is acceptable. Ensure the application demands the specific electrical characteristics of this silicon device rather than alternative materials.
Part Context
This component belongs to Microchip's portfolio of discrete semiconductor devices, specifically within the PIN diode segment. It shares the UMX9989 series designation with other variants such as the UMX9989-GM2, which differs primarily in its non-hermetic plastic surface-mount packaging. The SM suffix typically denotes the specific MELF package style used in this hermetic version.
Replacement Considerations
The UMX9989-GM2 is a related part within the same series but utilizes non-hermetic plastic SMT packaging. Verify if hermetic sealing is mandatory for the target application before considering this substitution. No other direct substitute part numbers are confirmed in the provided data.
