General Description

The FOD3120 is a 2.5A Output Current Gate Drive Optocoupler, capable of driving most 800V/20A IGBT/MOSFET. It is really suited for fast switching driving of power IGBT and MOSFETs used in motor control inverter applications, and high performance power system.

It utilizes Fairchild’s patented coplanar packaging technology, Optoplanar®, and optimized IC design to achieve high noise immunity, characterized by high common mode rejection.

It consists of a gallium aluminum arsenide (AlGaAs) light emitting diode optically coupled to an integrated circuit with a high-speed driver for push-pull MOSFET output stage.

Features

  • High noise immunity characterized by 35kV/µs minimum common mode rejection
  • 2.5A peak output current driving capability for most 800V/20A IGBT
  • Use of P-channel MOSFETs at output stage enables output voltage swing close to the supply rail
  • Wide supply voltage range from 15V to 30V
  • Fast switching speed
    • 400ns max. propagation delay
    • 100ns max. pulse width distortion
  • Under Voltage LockOut (UVLO) with hysteresis
  • Extended industrial temperate range, -40°C to 100°C temperature range
  • Safety and regulatory approved
    • UL1577, 5000 VRMS for 1 min.
    • IEC60747-5-2
  • RDS(ON) of 3OHM(typ.) offers lower power dissipation
  • >8.0mm clearance and creepage distance (option ‘T’)
