IR53H(D)420Absolute Maximum Ratings Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All volt- age parameters are absolute voltages referenced to COM, unless stated otherwise. All currents are defined positive into any lead. The thermal resistance and power dissipation ratings are measured under board mounted and still air conditions.
