Procurement Notes
Verify the specific suffix against the manufacturer's latest datasheet to confirm pinout and electrical tolerances. Ensure the component matches the required thermal management specifications for the intended enclosure. Confirm compliance with environmental regulations relevant to the deployment region before finalizing procurement orders.
Selection Notes
Select this component when a 100 V rating and 2 A continuous current capacity are required in a compact SMA package. The ultrafast recovery time makes it superior to standard rectifiers in high-frequency environments. Consider thermal derating factors if operating near the maximum junction temperature limit in confined spaces.
Part Context
This part belongs to the BYG22 series of ultrafast avalanche rectifiers from Vishay. The series offers various voltage ratings within the same DO-214AC footprint, allowing for design flexibility. The E3 suffix indicates lead-free construction compliant with international environmental standards.
