CotoMOS® C2211S/C3211S

When small size and high performance are needed, the SOP package, such as the C2211S or C3211S, is the industry choice. Both the C2211S and the C3211S feature low on-resistance, high load-current capacity, and low off-state leakage current. In addition, the C3211S offers two fully-independent form A channels for further space savings. Both relays are ideally suited to the needs of Test and Measurement, Industrial, and Telecommunications.
