C238S-A/ C338S-A SERIES CotoMOS® C238S-A/C338S-A When automotive grade performance and a small package size is required, the AEC- Q101 Certified C238S-A or C338S-A is your best choice. Configured in an industry standard SOP package, both the 4 pin, 1-Form A C238S-A and the 8 pin, 2 Form A C338S-A feature 600V switching for Automotive Battery Management and Energy Storage applications. The on-resistance of 40Ω-60Ω max. and output capacitance of 47 pF nominal allow for fast, high voltage switching in a small package. In addition, the C338S-A offers two fully-independent Form A channels for further space savings that can be configured in series mode for higher current switching requirements.
