Operation of this device beyond any one of these limits may
cause permanent damage. For reliable continous operation,
the device voltage and current must not exceed the maximum
operating values specified in the table on page one.
Bias Conditions should also satisfy the following expression:
IDVD < (TJ - TL) / RTH, j-l

Mounting Instructions
The data shown was taken on a 31mil thick FR-4 board with
1 ounce of copper on both sides.
The board was mounted to a baseplate with 3 screws as
shown. The screws bring the top side copper temperature
to the same value as the baseplate.
1. Use 1 or 2 ounce copper, if possible.
2. Solder the copper pad on the backside of the device
package to the ground plane.
3. Use a large ground pad area with many plated through-
holes as shown.
4. If possible, use at least one screw no more than 0.2 inch
from the device package to provide a low thermal resis-
tance path to the baseplate of the package.
5. Thermal resistance from ground lead to screws is
2 deg. C/W.
