IRS211(7,71,8)(S)
Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All
voltage parameters are absolute voltages referenced to COM. The thermal resistance and power
dissipation ratings are measured under board mounted and still air conditions.
