Procurement Notes

Verify the specific suffix 'CTG' against the official datasheet to confirm pinout configuration and compliance status. Ensure the ordering part number matches the exact package style required for your PCB footprint. Cross-reference the manufacturer's latest documentation to confirm active lifecycle status and any recent parameter updates before finalizing procurement.

Selection Notes

Select this component when designing circuits requiring fast switching speeds and low reverse recovery charge. The 120 V rating suits low-voltage DC bus applications. Evaluate the thermal resistance of the TO-220AB package against your heat dissipation needs. Consider the 20 A current rating relative to your peak load requirements and ambient operating temperatures.
