All the devices feature a low forward-voltage drop and special wide-bottom-plate designs that provide greater heat dissipation than other packages of similar sizes. The single or dual-chip, surface-mount SMPC (TO-277A) package features solder pads that are compatible with other SMDs, so no modification is needed to the PCB layout for use as higher-performing upgrades to existing devices.
