Single Diodes Procurement Notes
Verify the specific suffix 'M' indicates the M6 x 1 threaded stud base rather than the standard 1/4" 28UNF-2A thread. Confirm the exact voltage rating code within the 40HFL series matches the required circuit blocking voltage. Ensure mounting hardware compatibility with the specified metric thread size.
Single Diodes Selection Notes
Select this component when a 40 A continuous current rating and fast switching speeds are required in a stud-mountable form factor. Consider the 0.60 K/W thermal resistance for heatsink calculations. Verify that the M6 x 1 stud dimension fits the available mechanical mounting space compared to standard imperial threads.
Single Diodes Part Context
This part belongs to the VS-40HFL family of high-current fast recovery rectifiers. The series includes variants with different current ratings (70 A, 85 A) and voltage codes. The 'M' suffix specifically denotes the metric threading on the DO-5 package, distinguishing it from the standard imperial threaded versions found in the same product line.
