SNVS718E – JUNE 2011 – REVISED FEBRUARY 2013
Electrical Characteristics (continued)
Limits in standard type are for TJ = 25°C only; limits in boldface type apply over the junction temperature (TJ) range of -40°C
to +125°C. Minimum and Maximum limits are specified through test, design, or statistical correlation. Typical values represent
the most likely parametric norm at TJ = 25°C, and are provided for reference purposes only. Unless otherwise stated the
following conditions apply: VCC-VEE = 48V. See
(1) (2).

Junction to ambient thermal resistance is highly application and board layout dependent. Specified thermal resistance values for the
package specified is based on a 4-layer, 4"x3", 2/1/1/2 oz. Cu board as per JEDEC standards is used. For detailed information on
soldering plastic HTSSOP packages refer to the Packaging Data Book.
