• 1. 5V unidirectional ESD / TVS protection
  SD05T1G is designed for 5V lines and provides unidirectional transient voltage suppression, making it suitable for protecting low-voltage signal and supply-related lines against ESD and surge events.

  2. 350W peak pulse power capability
  The device can handle 350W peak pulse power under an 8/20μs waveform, helping absorb high-energy transient events before they damage downstream circuitry.

  3. 6.2V minimum breakdown voltage
  With a 6.2V minimum breakdown voltage, the device remains off during normal 5V operation and starts conducting during overvoltage events to clamp transient energy.

  4. Compact SOD-323 package
  The SOD-323 / SC-76 package is very small and suitable for dense PCB layouts, portable devices, embedded boards, and applications where board space is at a premium.

  5. Low leakage design
  The SD05T1 series is described by onsemi as having low leakage, helping minimize unwanted current flow during normal operation.

  6. 300mW steady-state power rating
  The device supports 300mW steady-state power dissipation, providing useful robustness for small-package circuit protection designs.

  7. Wide operating temperature capability
  The part is listed with a -55°C to +150°C junction temperature range, supporting use in harsh or thermally demanding electronics environments.

  8. RoHS-compliant SMD device
  SD05T1G is supplied as a surface-mount, tape-and-reel device and is listed as RoHS compliant by major distributors, making it suitable for automated production and modern electronics manufacturing.

SD05T1G is suitable for protecting low-voltage signal lines, I/O ports, and sensitive electronic circuits from transient voltage stress.
