SD03C

Component

TVS DiodeESD ProtectionSOD-3233.3V

The SD03C is a 1-line bi-directional TVS diode in a SOD-323 package, offering 200W peak pulse power and 3.3V reverse working voltage, ideal for ESD and surge protection in portable electronics.

Best for

  • ESD protection for data lines
  • Surge protection in portable devices

Avoid if

  • Signal lines exceed 3.3V DC
  • High-speed data lines requiring extremely low capacitance

Check before use

  • Clamping voltage at expected surge current
  • Capacitance impact on signal integrity
