Electrical Charateristics Specifications with standard type are for T
J = 25°C only; limits in boldface type apply
over the full Operating Junction Temperature (T
J) range. Minimum and Maximum limits are guaranteed through test, design, or
statistical correlation. Typical values represent the most likely parametric norm at T
J = 25°C, and are provided for reference
purposes only. Unless otherwise stated the following conditions apply: V
IN = 12V, RT = 50 k.
