High-Voltage Insulation Reliability

in Small Form Factor

Achieve reliable and high-insulation voltage as well as high-noise immunity in

high-power industrial applications with Fairchild’s FOD8320 and FOD8321,

advanced 2.5A current output gate driver optocouplers. Utilizing Fairchild’s

are housed in a wide body 5-pin small outline package. The FOD8320

offers a compact footprint while allowing for a creepage and clearance

distance of greater than 10mm and an internal insulation distance of

0.5mm. The FOD8321 is an alternative for customers who do not require

the 10mm creepage and clearance distance but need the small form factor.

Both devices provide an extended industrial temperature range

(-40°C to 100°C) and are well suited for fast switching of power IGBTs and

MOSFETs used in industrial inverter applications.
