Electrical Characteristics
Limits in standard type are for T
J = 25C only, and limits in boldface type apply over the junction temperature (TJ) range of
-40C to +125C. Minimum and Maximum limits are guaranteed through test, design, or statistical correlation. Typical values
represent the most likely parametric norm at T
J = 25C, and are provided for reference purposes only. Unless otherwise stated,
the following conditions apply: V
IN = 48V, RON = 200k
