Transient Voltage Suppressors (TVS)

ESD protectionTVS protectionSOT-23RS-48540 pF±30 kV ESD

WS712M is a 3-pin SOT-23 ESD/TVS protection device with two I/O pins and a common ground. It is specified for ±30 kV IEC 61000-4-2 ESD and 400 W peak pulse power.

Best for

  • RS-485 interface protection
  • Security-system transient protection
  • General industrial communication ports

Avoid if

  • The protected interface requires very low ESD capacitance
  • Signal voltage exceeds the applicable directional stand-off rating
  • A verified lifecycle or qualification status is mandatory

Check before use

  • Confirm directional voltage exposure relative to ground
  • Use a short, low-inductance connection from pin 3 to ground
  • Validate residual clamping voltage at the expected surge current
