Hi Magnus,
We’re sorry that the quality & environmental data portion of the 66AK2H12 webpage is not fully updated; it can take a year or more to fully validate FIT/DPPM for a new technology as full validation requires volume data. However, the device is fully qualified and it was designed to support 50 FIT at 100K POH at Tj=105C. The device itself is RoHOS-compliant and, accordingly, supports JEDEC environmental condition of MSL-4 under Pb-free conditions.
Regards, Bill
