Notes: 
1. 
R
θ
JA 
is the sum of the junction-to-case and case-to-ambient thermal resistance where the case thermal reference is defined as the solder mounting surface of 
the drain pins.  R
θ
JC 
is guaranteed by design while R
θ
CA 
is determined by the user's board design. 
a) R
θ
JA 
is 100
°
C/W (steady state) when mounted on a 1 inch2 copper pad on FR-4. 
b) R
θ
JA 
is 125
°
C/W (steady state) when mounted on a minimum copper pad on FR-4.

Pulse Test: Pulse Width < 300
μ
s, 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.
