• DC-DC converter freewheeling paths

Procurement Notes

Verify the specific manufacturer source, as historical data references both Sanyo and onsemi due to corporate acquisitions. Confirm the exact package marking and datasheet version to ensure compatibility with current design requirements. Check for obsolete status indicators in official catalogs before finalizing procurement plans.

Selection Notes

Select this component when a 50V rating and 12.5A continuous current capacity are required in a flange mount form factor. Consider the low forward voltage characteristic for efficiency optimization in power conversion applications. Ensure the thermal interface matches the TO-3PML mounting style for adequate heat dissipation.

Part Context

This part belongs to the Schottky rectifier diode array category within onsemi's discrete semiconductor portfolio. It serves as a high-current, low-voltage solution for power electronics. The TO-3PML package distinguishes it from surface-mount alternatives, targeting applications requiring direct chassis or heatsink mounting for superior thermal performance.
