These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.

The junction-to-ambient thermal resistance under natural convection is obtained in a simulation on a JEDEC-standard, High-K board, as

specified in JESD51-7, in an environment described in JESD51-2a.

(3)

The junction-to-case(top) thermal resistance is obtained by simulating a cold plate test on the package top. No specific JEDEC-standard

test exists, but a close description can be found in the ANSI SEMI standard G30-88.

(4)

The junction-to-board thermal resistance is obtained by simulating in an environment with a ring cold plate fixture to control the PCB

temperature, as described in JESD51-8.

The junction-to-case(bottom) thermal resistance is obtained by simulating a cold plate test on the exposed (power) pad. No specific

JEDEC standard test exists, but a close description can be found in the ANSI SEMI standard G30-88.

Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings

only. Functional operation of the device under any conditions beyond those indicated under recommended operating conditions is not

implied. Exposure to absolute maximum rated conditions for extended periods of time may affect device reliability.
