Junction-to-ambient thermal resistance is based on measurements on a horizontal-single-sided
Printed Circuit Board per SEMI G38-87 in natural convection.(SEMI is Semiconductor Equipment
and Materials International, 805 East Middlefield Rd., Mountain View, CA 94043, [phone])
Junction-to-case thermal resistance is based on measurements using a cold plate per SEMI G30-
88, with the exception that the cold plate temperature is used for the case temperature.
These are measured values. See note 1 for test board conditions.
These are measured values; testing is not complete. Values were measured on a non-standard
four-layer thermal test board (two internal planes) at one watt in a horizontal configuration.
