Single Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging configuration, as variations exist between cut tape, reel, and mouse reel formats. Confirm RoHS compliance status and REACH SVHC declarations directly from the latest product documentation prior to integration. Ensure the procurement channel provides authentic components with traceable manufacturing data to prevent counterfeit risks.

Single Diodes Selection Notes

Select this component when an ultra-fast recovery time is critical for minimizing switching losses in high-frequency circuits. The 400 V reverse voltage rating makes it suitable for medium-voltage rectification tasks. Consider the DO-214AC package dimensions for PCB layout constraints. Evaluate the 1 A current capacity against peak load requirements to ensure adequate thermal headroom under continuous operation conditions.

Single Diodes Part Context

The ES1G belongs to the ESxG series of ultra-fast recovery rectifiers from onsemi. This family is designed for general-purpose use in applications requiring fast switching speeds. The device utilizes silicon p-n junction technology within a plastic SMA package. It serves as a standard solution for replacing slower standard recovery diodes in modern high-efficiency power supply designs.

Single Diodes Replacement Considerations

Cross-reference with other manufacturers' 1 A, 400 V ultra-fast recovery diodes in the DO-214AC package. Verify that substitute parts match the 35 ns reverse recovery time and 1.3 V forward voltage specifications to maintain circuit performance integrity.
