These Linear MOSFET Power Modules (Part Numbers: APTMLxxx…) are used to provide a wide range of solutions in any linear, high-power density application where conventional switch-mode operation is either not allowed or not possible. They are ideal for circuits in which power devices must operate with high voltage and high current simultaneously, in near DC conditions. These MOSFET power modules are specifically designed to meet a wider guaranteed Forward Safe Operating Area, ensuring improved system reliability, with the minimum number of devices (to achieve given power levels).

 With their positive temperature coefficient thermistor included, these new linear MOSFETs from Microsemi are more stable and much less prone to thermal runaway. The included series shunt resistors allow current to be precisely controlled. This allows the modules to be easily used in parallel with an equal power dissipation balance. There is no need for additional safety margin judgment, which is usually required when switch-mode devices are used in parallel.

 Highlights of this 10 module product line include: 

  • ·100V, 200V, 500V, 600V and 1000V MOSFET Switches available.

  • ·Choice of Single Switch (SP1 package) and Dual Switch (SP3 package) models.

  • ·All employ ALN substrates to achieve highest possible power density.

  • ·Modules may be connected in series for greater than 1000V operation.
