IR22771S/IR21771S(PbF)
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 VSS; all currents are defined positive into any lead. The Thermal Resistance and Power
Dissipation ratings are measured under board mounted and still air conditions.
