1700V High-voltage Isolated Switches

22/11/2024

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.

Main Features

  • Normally Open (1-Form-A) Device
  • Opto-Compatible Input
    - No Optical Attenuation and Aging Problems of Traditional Optocouplers
    - 5.5-V Maximum Input Reverse Voltage
  • Integrate Back-to-Back SiC MOSFET
    - Output Off-State Voltage Up to 1700V (min)
    - 1-μA (max) Output Off-State Leakage Current
    - 50-Ω (typ) Output On-State Resistance
    - Output On-State Current Up to 50mA
    - Turn-On and Turn-Off Time < 300μs
  • Wide Operating Temperature Range: –40°C to 125°C
  • High CMTI: ±150kV/µs (typ)
  • Low EMI: Passed Test According to CISPR32 Class B Standard With 2-Layer PCB Design
