Procurement Notes
Verify the specific suffix designation against official Comchip Technology documentation to confirm automotive grade classification and exact electrical tolerances. Ensure the ordering part number matches the required package type and lead time requirements. Cross-reference datasheet revisions to confirm compliance with current RoHS directives and material declarations before final procurement decisions.
Selection Notes
Select this component when automotive reliability standards are required alongside super fast recovery performance. The 400 V rating suits intermediate voltage DC bus applications. Compare the 50 ns recovery time against system switching frequencies to ensure minimal reverse recovery charge losses. Verify that the SMA package footprint aligns with the PCB layout constraints and thermal management strategy.
Part Context
This device belongs to Comchip Technology's automotive rectifier series, designed specifically for harsh environments. It complements other SMA packaged diodes like the ES1J-HF but offers distinct automotive qualification. The product line emphasizes robustness and consistent performance under varying thermal conditions typical in vehicle electronic control units.
Replacement Considerations
Official parametric equivalents listed by distributors include the ES1G-HF from Comchip Technology. Verify pinout compatibility and exact electrical parameter overlaps before substitution. Ensure any replacement maintains the same automotive qualification status if required by the design.
