Single Diodes Procurement Notes

Verify the specific suffix 'M' against official datasheets to confirm lead-free plating compliance and packaging details. Ensure that the ordering information matches the exact electrical ratings required for the target application circuit. Cross-reference the manufacturer part number with authorized distributors to confirm current availability status and valid documentation versions before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when a high-voltage, high-current standard recovery diode is required in a stud-mount form factor. The 800 V rating provides sufficient margin for common three-phase bridge rectifier configurations. Consider the 180°C junction temperature capability for environments where active cooling may be limited or ambient temperatures are elevated compared to standard silicon limits.

Single Diodes Part Context

This device belongs to the Vishay 70HF series of high-current rectifiers. The series offers various voltage ratings while maintaining a consistent 70 A current capacity and DO-5 package footprint. This standardization allows designers to swap voltage ratings within the same family without altering the mechanical layout or mounting hardware of the power assembly.
