G66 Equivalent & Substitute Parts Reference
Part Overview
The G66, manufactured by Goford Semiconductor, is a P-Channel MOSFET in the Transistors, FETs, MOSFETs category. It features a maximum drain current of 5.8A (Tc), a max Rds(On) of 45mOhm at 4.1A, 4.5V, a drive voltage of 2.5V, 4.5V, and is provided in a 6-DFN (2x2) surface-mount package. The device has a maximum power dissipation of 1.7W (Tc) and operates from -55°C to 150°C. The product is currently active, but alternative models are necessary to ensure supply continuity, manage inventory, and address RoHS and compliance requirements.

Substitute Part Grouping Explanation
Substitution is performed strictly on identical electrical and mechanical parameters. For the P-Channel MOSFET category, key parameters include current rating (Id), Rds(On), gate threshold voltage (Vgs(th)), gate-source voltage (Vgs), package type, power dissipation, and mounting method. Substitute parts must match these values precisely to ensure full electrical and mechanical compatibility.
