Product details

Temperature range and environment

The CSD17581Q5AT: Junction temperature spans -55°C to 150°C, which covers automotive under-hood, industrial motor drives, and outdoor telecom equipment without needing a separate AEC-Q line item. The 83 W power dissipation at the case (Tc) assumes a proper thermal interface to a heatsink or PCB copper plane; the 3.1 W at ambient (Ta) is the free-air limit — derate from there if the board is in a sealed enclosure.

Lifecycle and compliance

No last-time-buy or end-of-life notice is on record for this order code. For current pricing and availability, submit an RFQ — the part is sourced through independent distribution and quoted to order.
