CotoMOS® CS128 High-Current MOSFET Relay
Ideal for Battery Management applications, Electric Vehicles and Solar Arrays

Coto Technology's 128 Series MOSFET Relay features a high-current switching capability to 4.5A with a typical low on-resistance of 0.03Ω

The CotoMOS® High-Current 128 Series MOSFET Relay is an SMD packaged, optically isolated solid-state relay (OISSR) capable of switching a 4.5 A load current (IL), thanks, in part, to its extremely low on-resistance (Ron) – typically about 0.03 Ω. Since the power dissipated in its junctions is equal to IL2 x Ron, the CotoMOS® 128 MOSFET Relay can switch an amazing amount of electrical power in a very small package, even without heat-sinking. Designed for Battery Management, Solar Arrays, Industrial Automation, Control, Instrumentation, and Data Acquisition, the High-Current CotoMOS® MOSFET 128 Series is capable of handling 40V AC and DC load conditions.
