Single Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm thread specifications and polarity. The 'R' designation indicates a stud anode configuration; ensure this matches the required circuit topology. Confirm compliance requirements such as RoHS status directly through authorized distributors or the manufacturer before finalizing procurement.

Single Diodes Selection Notes

Select this component when a high-current standard recovery diode with a stud anode configuration is required. Ensure the application operates within the specified junction temperature limits and that the mounting torque adheres to the datasheet recommendations for lubricated or non-lubricated threads. Verify that the 100 V rating provides sufficient margin for the peak reverse voltage in the target circuit.

Single Diodes FAQ

What does the 'R' suffix indicate in the part number VS-70HFR10?

The 'R' suffix denotes a stud anode version, meaning the anode is connected to the mounting stud rather than the cathode.

What is the maximum allowable mounting torque for this device?

For a non-lubricated thread on a hexagon, the maximum torque is 4.2 N·m (37 lbf·in). For a lubricated thread on a nut, it is 2.3 N·m (20 lbf·in).
