(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 specifications, see Electrical
Characteristics. Specifications do not apply when operating the device outside of its rated operating conditions.
(2) If Military/Aerospace specified devices are required, contact the Texas Instruments Semiconductor Sales Office/Distributors for
availability and specifications.
(3) The human body model is a 100 pF capacitor discharged through a 1.5k resistor into each pin.
(4) The machine model is a 220 pF capacitor discharged directly into each pin.
(5) At elevated temperatures, device power dissipation must be derated based on package thermal resistance and heatsink thermal values.
θ
J-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 θ
J-S
value of 4°C/W can be
assumed. θ
J-A
for DDPAK/TO-263 devices is approximately 35°C/W if soldered down to a copper plane which is at least 1 square inches
in area. If power dissipation causes the junction temperature to exceed specified limits, the device will go into thermal shutdown.
