IR2520D(S)& (PbF)
Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage param-
eters 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.

Note 1: This IC contains a zener clamp structure between the chip VCO and COM, which has a nominal breakdown voltage
of 6V. Please note that this pin should not be driven by a DC, low impedance power source greater than 6V.
Note 2: This IC contains a zener clamp structure between the chip VCC and COM, which has a nominal breakdown voltage
of 15.6V. Please note that this supply pin should not be driven by a DC, low impedance power source greater than the
VCLAMP specified in the Electrical Characteristics section.
Recommended Operating Conditions
For proper operation the device should be used within the recommended conditions.
