Procurement Notes

Verify the specific part number suffix against official documentation to confirm packaging type and compliance status. The provided datasheet indicates that ordering suffixes define packing codes and version codes, such as RoHS compliance or tape and reel specifications. Ensure the selected variant matches the required mechanical and environmental standards for the intended assembly process.

Selection Notes

Select this component based on its 40 Ampere continuous current rating and 40 Volt reverse voltage blocking capability. Consider the thermal management requirements associated with the TO-247AD package and the specified 1.5°C/W thermal resistance. Verify that the application operates within the -55°C to +150°C junction temperature range and accounts for current derating factors if the case temperature exceeds 90°C.

Part Context

This component belongs to the SB4020PT series of Schottky Barrier Rectifiers produced by Panjit International Inc.
