Single Diodes Procurement Notes

Verify the specific suffix against the manufacturer datasheet to confirm exact thermal resistance and terminal specifications. Ensure the procurement documentation matches the DO-205AA package outline. Confirm RoHS compliance status if required by the target assembly process. Cross-reference the part number with official Vishay databases to avoid obsolete variants.

Single Diodes Selection Notes

Select this component when high current capacity and ruggedness are prioritized over low forward voltage drop. The stud mount interface requires compatible heatsinking infrastructure. Evaluate thermal management requirements based on the 150 A rating and ambient conditions. Consider the 400 V blocking voltage relative to the system's peak reverse stress levels.

Single Diodes Part Context

This component belongs to Vishay's KR series of high-power rectifiers. These devices utilize planar passivation technology to ensure stability under harsh conditions. The series is engineered for applications requiring high surge current withstand capabilities and reliable long-term operation in power conversion systems.

Single Diodes Replacement Considerations

Check for direct cross-reference numbers such as MUR1560 or similar high-current stud-mount diodes from other manufacturers. Verify that any substitute matches the 150 A average forward current and 400 V reverse voltage ratings. Ensure the replacement package maintains the same stud mounting dimensions.
