(1)

Absolute maximum ratings indicate limits beyond which damage to the component may occur. Operating ratings indicate conditions for

which the device is intended to be functional, but do not ensure specific performance limits. For ensured specifications, see Electrical

Characteristics. Specifications do not apply when operating the device outside of its rated operating conditions.

(2)

The human body model is a 100 pF capacitor discharged through a 1.5k resistor into each pin.

(3)

The machine model is a 220 pF capacitor discharged directly into each pin. The machine model ESD rating of pin 5 is 100V.

(4)

At elevated temperatures, device power dissipation must be derated based on package thermal resistance and heatsink thermal values.

θJ-A for TO-220 devices is 65°C/W if no heatsink is used. If the TO-220 device is attached to a heatsink, a θJ-S value of 4°C/W can be

assumed.

θJ-A for TO-263 devices is approximately 40°C/W if soldered down to a copper plane which is at least 1.5 square inches in

area.

θJ-A value for typical SOIC-8 PC board mounting is 166°C/W. If power dissipation causes the junction temperature to exceed

specified limits, the device will go into thermal shutdown.
