Overview
The UM9401SM is a silicon PIN diode manufactured by Microchip Technology. It utilizes a hermetic MELF (Metal Electrode Leadless Face) package design, ensuring robust environmental sealing and reliability for demanding applications. The component is classified as a PPIN device, indicating specific structural properties for high-speed switching or RF applications. This part is available through Factory Special Order channels, requiring direct engagement with the manufacturer to confirm current production status and ordering requirements.
Feature Summary
- Hermetic sealing within a MELF package for enhanced environmental protection
- Silicon-based PPIN construction for specialized diode performance
- Designed for reliable signal conditioning in critical systems
Applications
- High-speed switching circuits
- RF signal processing applications
- Critical system components requiring hermetic reliability
Procurement Notes
This component is designated as a Factory Special Order item. Availability is not standard; potential buyers must contact Microchip Technology directly to obtain a quote. Verification of current pricing, lead times, and specific ordering requirements is mandatory before proceeding. Do not assume stock availability from general distributors without explicit confirmation from the manufacturer.
Selection Notes
Select the UM9401SM when hermetic sealing and silicon PPIN characteristics are required for specific diode functions. Verify that the MELF package form factor meets board layout constraints. Confirm compatibility with intended voltage and current specifications through official datasheets, as generic descriptions do not define electrical limits.
Part Context
Microchip Technology produces this component under its discrete semiconductor portfolio. The UM9401SM represents a specialized hermetic diode solution, distinct from standard surface-mount devices. It is categorized alongside other precision passive components designed for high-reliability environments where standard packaging may be insufficient.
Replacement Considerations
No public substitute part numbers are documented. As a Factory Special Order item, cross-referencing requires direct consultation with Microchip Technology engineering support to ensure functional equivalence.
