Notes:

1. All voltages referenced to SOURCE and Secondary GROUND,

T

A = 25 °C.

2. Maximum ratings specified may be applied one at a time without

causing permanent damage to the product. Exposure to Absolute

Maximum Ratings conditions for extended periods of time may

affect product reliability.

3. Higher peak drain current is allowed while the drain voltage is

simultaneously less than 400 V.

4. Normally limited by internal circuitry.

5. 1/16” from case for 5 seconds.

6. Maximum drain voltage (non-repetitive pulse) ........-0.3 V to 750 V

Maximum continuous drain voltage ........................-0.3 V to 650 V

Notes:

1. Thermal resistance value

q

JA is for the primary power device

junction to ambient only. Testing performed on custom thermal

test PCB consisting of 2 layers of 2 oz. Cu with the package

mounted to the top surface and connected to a bottom layer Cu

heatsinking area of 550 mm^2. Connection between the two

layers was made by 82 vias in a roughly 5x17 matrix outside the

package mounted area. Vias were spaced at 40 mils, were 12 mils

diameter, and plated through but not filled..
