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, 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:
Because of the IR51H214's application specificity toward off-line supply systems, this IC contains a
zener clamp structure between the chip VCC and COM which has a nominal breakdown voltage of
15.6V. Therefore, the IC supply voltage is normally derived by current feeding the VCC lead
(typically by means of a high value resistor connected between the chip VCC and the rectified line
voltage and a local decoupling capacitor from VCC to COM) and allowing the internal zener clamp
circuit to determine the nominal supply voltage. Therefore, this circuit should not be driven by a DC,
low impedance power source of greater than VCLAMP.
