Diode Arrays Procurement Notes

Verify the specific ordering suffix 'B' corresponds to the TO-247-3 package configuration before procurement. Confirm RoHS compliance status as indicated on the datasheet revision date. Ensure thermal management designs account for the 0.4 °C/W junction-to-case resistance rating under actual operating conditions.

Diode Arrays Selection Notes

Select this component when high-temperature operation up to 175°C is required or when minimizing switching losses is critical. The TO-247-3 package provides enhanced thermal performance suitable for high-power density applications. Consider the positive temperature coefficient for parallel configurations requiring balanced current sharing without additional ballasting.
