APPLICATIONS INFORMATION
WARNING
—
These devices are designed to be operated at lethal voltages and energy levels. Circuit
designs that embody these components must conform with applicable safety requirements. Precau-
tions must be taken to prevent accidental contact with power-line potentials. Do not connect
grounded test equipment.
The use of an isolation transformer is recommended during circuit development and breadboarding.
The power MOSFET outputs of these devices are similar to the International Rectifier type IRFBC40. These devices
feature an excellent combination of fast switching, ruggedized device design, low on-resistance, and cost effectiveness.
Recommended mounting hardware torque:
4.34 – 5.79 lbf•ft (6 – 8 kg•cm or 0.588 – 0.784 Nm).
Recommended metal-oxide-filled, alkyl-degenerated oil base, silicone grease:
Dow Corning 340, or equivalent
