Technical details

Temperature range and environment

Rated for -40°C to 125°C junction temperature, this part handles the thermal swings you see in outdoor telecom cabinets, engine-bay-adjacent electronics, or factory-floor motor drives. No AEC-Q100 cert in the listing, so if you need automotive-grade qualification for under-hood deployment, that is a separate check — but the temperature range itself is industrial-plus.

Sourcing and lifecycle

Lifecycle status is Active, with ROHS3 compliance confirmed. That means you can qualify it into a new BOM without worrying about a sudden discontinuation mid-production.
