Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm exact electrical tolerances and packaging variations. Ensure the procurement channel provides valid traceability for RoHS compliance status. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current production status and availability before finalizing orders.

Selection Notes

Select this component when designing systems requiring high current capacity in a compact three-phase configuration. Verify that the mechanical footprint matches the MT-K module dimensions and that the cooling solution supports the thermal requirements at +150°C. Confirm that the 1.4 kV reverse voltage rating exceeds the maximum line-to-line voltage peaks in the target application circuit.

Part Context

This part belongs to the 160MT series of three-phase bridge rectifiers from Vishay. It shares the MT-K package form factor with other variants in the lineup but differs in current and voltage ratings. The series is engineered for robust performance in demanding power electronics applications where reliability under high thermal stress is critical.

Replacement Considerations

Consult official Vishay substitution guides for compatible alternatives. Verify pinout compatibility and thermal resistance characteristics when considering cross-brand replacements. Ensure any substitute meets or exceeds the 160 A current and 1.4 kV voltage specifications.
