Note 1

Thermal resistance without a heatsink for junction-to-case temperature is 3 CW Thermal resistance case-to-ambient is 40 CW

Note 2

Tested Limits are guaranteed and 100% production tested

Note 3

Design Limits are guaranteed (but not 100% production tested) over the indicated temperature and supply voltage range These limits are not used to

calculate outgoing quality levels

Note 4

Note 5

(See Typical Performance Characteristics and Applications Section)

Note 6

To ensure constant junction temperature low duty cycle pulse testing is used
