IR53H(D)420(-P2)
NOTE 1:
This IC contains a zener clamp structure between V
CC
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 V
CLAMP
specified in the Electrical Characteristics Section

Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All volt-
age parameters are absolute voltages referenced to COM, unless stated otherwise. All currents are defined
positive into any lead. The thermal resistance and power dissipation ratings are measured under board
mounted and still air conditions.
