... Rating applies to applications using heat sinking to control case temperature. Derate linearly at 16.4 mW/ C for case temperature above Rating applies to applications not using a heat sinking; devices in free air only. Derate linearly at 6.3 mW/ C for ambient temperature above 70 C. Model MAT02AH MAT02EH MAT02FH NOTES 1 Burn-in is available on commercial and industrial temperature range parts in TO-can packages ...
