Single Diodes Procurement Notes
Verify the manufacturer part number US1M against Shenzhen Slkormicro Semicon Co., Ltd. documentation. Confirm the SMA (DO-214AC) package type and 1000 V rating match system requirements. Ensure compliance with RoHS standards and UL 94V-0 classification if specified in design constraints. Cross-reference datasheet electrical limits with operational conditions.
Single Diodes Selection Notes
Select this component for applications requiring fast recovery times and surface mount integration. The 1000 V reverse voltage rating suits high voltage rectification tasks. Verify thermal management capabilities within the -55°C to +150°C operating range. Consider the 75 ns reverse recovery time for high-frequency switching designs where standard recovery diodes may be insufficient.
Single Diodes Part Context
The US1M belongs to the US1 series of ultra-fast recovery rectifiers from Shenzhen Slkormicro Semicon Co., Ltd. This series includes variants with different reverse voltage ratings, such as US1A through US1K. All members share the same 1.0 A current rating and SMA package, differing primarily in their peak reverse voltage specifications.
Single Diodes Replacement Considerations
Compatible substitutes include ES1M from SMC Diode Solutions and US1MW from SKTECHNOLOGY. These alternatives offer similar 1000 V, 1 A specifications and DO-214AC packaging. Verify pinout compatibility and electrical parameters before substitution.
