Figure 7 shows a circuit with four parallel NDP706A
Application Hints
manufacturer for all of the MOSFETs in the array Also all
MOSFETs should have the same style heat sink or ideally
all mounted on the same heat sink The electrical connec-
tion of the MOSFETs should get special attention With typi-
cal R
poor electrical connection for one of the MOSFETs can ren-
der it useless in the circuit

circuit will provide a typical maximum load current of 150A
at 25 C and a typical maximum load current of 100A at
125 C The maximum dissipation per MOSFET will be
nearly 20W at 25 C and 12 5W at 125 C With up to 20W
being dissipated by each of the four devices an effective
heat sink will be required to keep the T
when operating near the maximum load currents
