CA-IS3417WT
Active
1700V High-voltage Isolated Switches
The CA-IS3417WT is low-EMI, opto-compatible input, reinforced isolated HV (high-voltage) switch. The input stage (primary side) is an emulated diode (e-diode). While maintaining the input characteristics of the optocoupler, it also has better consistency, long-term stability and higher reliability. Unlike traditional optical MOS relays, this device'ssignal transmission characteristics will not attenuate over time. Also, compared with traditional mechanical relays, the CA-IS3417WT features long term reliability and excellent aging characteristics.
The output stage (secondary-side) of CA-IS3417WT integrates back-to-back SiC MOSFET with up to 1700-V standoff voltage. It can operate stably at higher ambient temperatures because of SiC MOSFET’s better hightemperature characteristics and reliability.
The CA-IS3417WT devices are packaged in wide body, 12pin SOIC packages and the pinout is compatible with most of industry standard optical MOS relays. The isolation voltage between primary side and secondary-side is up to 5kVRMS @ 1 minute. This device is specified over the extended industrial temperature range of –40°C to 125°C.
