Diode Arrays Procurement Notes

Verify the specific ordering suffix to ensure correct packaging and terminal configuration. Confirm that the replacement part number matches the original electrical ratings, including the 1400 V reverse voltage and 600 A current capacity. Check for any changes in mechanical dimensions or mounting hole patterns when substituting with equivalent modules from other manufacturers.

Diode Arrays Selection Notes

Select this module for applications requiring high-voltage isolation and significant current handling. The POW-R-BLOK design offers improved current capability due to low thermal impedance. Ensure the cooling system can handle the thermal dissipation requirements associated with 600 A operation. Consider the physical size constraints provided by the outline dimensions before integration into the final assembly.
