Procurement Notes

This component is designated as not recommended for new designs. Production is limited strictly to supporting existing customers. Engineers initiating new projects should select alternative active components from the manufacturer's current portfolio. Verify specific ordering suffixes and packaging configurations directly with authorized distributors or the manufacturer before procurement to ensure compatibility with legacy systems.

Selection Notes

Select this part only for retrofitting or maintaining existing equipment where the RB298T100HZC9 is already specified. Due to its discontinued status for new designs, availability may be constrained. Ensure that the TO-220FN package dimensions and thermal requirements match the existing board layout. Consider the 30 A current rating and 100 V blocking capability when validating circuit performance under load conditions.

Part Context

The RB298T100HZC9 belongs to ROHM Semiconductor's RB298 series of high-reliability Schottky barrier diodes.
