Scrs Procurement Notes

Verify the specific suffix 'MPBF' against official Vishay documentation to confirm RoHS compliance status and lead time requirements. Ensure that the ordering information matches the exact part number designation in the manufacturer's latest datasheet. Confirm that the TO-209AC package dimensions align with the intended chassis mounting hardware specifications before procurement.

Scrs Selection Notes

Select this component when a standard recovery SCR with 1.2 kV blocking voltage and 172 A RMS current capacity is required. The TO-209AC package facilitates direct chassis mounting, which is advantageous for high-power industrial environments. Consider the 110 A average current rating for continuous duty cycles and ensure adequate heat sinking is available to maintain junction temperatures within the specified operating range.
