Notes
a. Surface Mounted on 1” x 1” FR4 Board.
b. Junction-to-foot thermal impedance represents the effective thermal impedance of all heat carrying leads in parallel and is intended for use in conjunction with
the thermal impedance of the PC board pads to ambient (RthJA = RthJF + RthPCB-A). It can also be used to estimate chip temperature if power dissipation and
the lead temperature of a heat carrying (drain) lead is known.
