Fairchild releases gate drive optocouplers

A Fairchild Semiconductor product story

Edited by the Electronicstalk editorial team Dec 19, 2008

Fairchild Semiconductor has released the FOD3120 and FOD3150 2.5A and 1A current gate drive optocouplers, which the company says achieve a high common mode rejection (CMR) rating.

Fairchild said the gate drive optocouplers can drive 1200V/20A IGBTs and MOSFETs even in the noisiest industrial environment.

This noise immunity is instrumental in preventing unwanted switching, which can lead to shoot-through current and damage to the IGBT.

These devices also offer tight pulse width distortion (100ns), offering smaller filters, which consume less power and lead to improved power efficiency.

With a 1414V peak working voltage, these gate drive optocouplers are able to accommodate high voltage IGBTs.

The FOD3120 and FOD3150 utilise lead-free (Pb-free) terminals and have been characterised for moisture sensitivity in accordance with the Pb-free reflow requirements of the joint IPC/JEDEC standard J-STD-020.
