Notes:

1: R JA is determined with the device mounted on a 1 in

2 oz. copper pad on a 1.5 x 1.5 in. board of FR-4 material. R

JCis guaranteed by design while R JA is determined by the

user's board design.

(a) R JA = 86°C/W when mounted on a 1in

2 pad of 2 oz copper, 1.5" x 1.5" x 0.062" thick PCB. For single operation.

(b) R JA = 173°C/W when mounted on a minimum pad of 2 oz copper. For single operation.

(c) R JA = 69

oC/W when mounted on a 1in2 pad of 2 oz copper, 1.5” x 1.5” x 0.062” thick PCB, For dual operation.

(d) R JA = 151

oC/W when mounted on a minimum pad of 2 oz copper. For dual operation.

2: Pulse Test : Pulse Width < 300us, Duty Cycle < 2.0%

3: The diode connected between the gate and source serves only as protection against ESD. No gate overvoltage rating is implied.
