Procurement Notes

Verify the HE3 suffix indicates high reliability grade and AEC Q101 qualification. Confirm the /81 suffix corresponds to tape reel delivery mode with a base quantity of 800 units per reel. Ensure the component meets RoHS 2002/95/EC and WEEE 2002/96/EC directives as specified in the datasheet.

Selection Notes

Select this component for applications requiring fast switching rectification with an 8.0 A average forward current rating and a 200 V reverse voltage blocking capability. Consider the TO-263AB surface mount package for board space constraints. Evaluate thermal resistance from junction to case (2.0 °C/W) against system cooling requirements.

Part Context

This part belongs to the BY229(X,B)-200 thru BY229(X,B)-800 series of fast switching plastic rectifiers. The 'B' designation identifies the TO-263AB package variant. The HE3 suffix denotes the high reliability grade, which includes AEC Q101 qualification and compliance with JESD 201 class 2 whisker test standards.

Replacement Considerations

Cross-reference other parts within the BY229B-200 series or equivalent Vishay fast switching rectifiers. Verify that any substitute matches the 8.0 A current rating, 200 V reverse voltage, TO-263AB package, and specific HE3 reliability grade requirements.
