TA = 25°C unless otherwise noted. Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply when operating the device outside of its operating ratings. The maximum allowable power dissipation is a function of the maximum junction temperature, TJ(Max), the junction-to-ambient thermal resistance, θJA, and the ambient temperature, TA. Note 2. This device is not guaranteed to operate beyond its specified operating rating. Note 3. Mounted on 1 square-inch pad of 2 oz. copper. Note 4. IC devices are inherently ESD sensitive. Handling precautions required. Note 5. Pulse width < 300µs with <2% duty cycle. Note 6. Dynamic specifications are guaranteed by design. Note 7. Body diode current conduction is not recommended.
