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. The thermal resistance and power dissipation ratings are measured
under board mounted and still air conditions.

structure between the chip V
CC
and COM which has a nominal breakdown voltage of 15.6V. Therefore, the IC
supply voltage is normally derived by forcing current into the supply lead (typically by means of a high value
resistor connected between the chip V
CC
and the rectified line voltage and a local decoupling capacitor from
V
CC
to COM) and allowing the internal zener clamp circuit to determine the nominal supply voltage. There-
fore, this circuit should not be driven by a DC, low impedance power source of greater than V
CLAMP
.
Note 1:
Because of the IR2151’s application specificity toward off-line supply systems, this IC contains a zener clamp
