*Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.

**These maximum stresses are to be applied only after the chip is properly bonded to a heat sink. Applying current to a bare chip can damage the device.


Dimensions


Chip Dimensions (w*l*h) = 360±10μm*1500±10μm*100±10

COC Dimensions (w*l*h) = 5.0±0.05mm*3.25±0.05mm*0.3±0.025mm

ESD and EOS

Switching transients can cause electrical overstress (EOS) damage in a chip.

EOS may result from improper ESD handling, improper power sequencing, a faulty power supply or an intermittent connection.

 

 Proper turn-on sequence:

a. All ground connections

b. Most negative supply

c. Most positive supply

d. All remaining connections

 Reverse order to turn-off.
