Fairchild Debuts 100V and 150V SO-8 MOSFETs

Fairchild Semiconductor International (South Portland, ME) introduced the first six products in a new family of medium-voltage, PowerTrench® MOSFETs in SO-8 packages for applications requiring efficient, high-frequency switching. The products offer low total gate charge and Miller charge essential for fast switching, and are avalanche-rated and extensively tested. The new 100V/150V MOSFETs are suitable for dc/dc power supplies for communications and industrial markets. Typical applications include popular telecom brick designs, which are optimized by using the 100V MOSFET in half- or full-bridge topologies, and the 150V MOSFET in forward topologies.

The new range of 100V (FDS3672, FDS3682, FDS3692 and FDS3992) and 150V (FDS2572 and FDS2582) MOSFETs provide a choice of RDS(on) versus gate charge trade-offs to benefit each application’s particular operating conditions. To further improve switching characteristics in power supply designs, the internal gate resistance is greatly reduced, allowing the benefits of the low gate charge to be realized.

Samples and production quantities are available now. Prices range from $0.61 to $1.35 for 1,000 pieces. Delivery is eight weeks ARO.
