All voltage parameters are absolute voltages referenced to COM, all currents are defined positive into any lead. The thermal resistance and power dissipation ratings are measured under board mounted and still air conditions. Symbol Definition Min. Max.

Please note that this supply pin should not be driven by a DC, low impedance power source greater than the V specified in the Electrical Characteristics section. CLAMP Note 2: Enough current should be supplied into the V pin to keep the internal 15.6V zener clamp diode on this pin CC regulating its voltage, V . CLAMP 2 www.irf.com
