The SP1220 unidirectional TVS is fabricated in a proprietary silicon avalanche technology. These diodes provide a high ESD (electrostatic discharge) protection level for electronic equipment. The SP1220 TVS can safely absorb repetitive ESD strikes of ±30 kV (contact and air discharge as defined in IEC 61000-4-2) without any performance degradation. Additionally, each TVS can safely dissipate a 20A 8/20 surge event as defined in IEC 61000-4-5 2nd Edition.

Features:

  • ESD, IEC 61000-4-2, ±30kV contact, ±30kV air

  • EFT, IEC 61000-4-4, 40A (5/50ns)

  • Lightning, 20A (8/20 as defined in IEC 61000-4-5 2nd edition)

  • AEC-Q101 qualified

  • Lead free and RoHS compliant

  • Moisture Sensitivity Level(MSL -1)

Applications:

  • Switches / Buttons

  • Test Equipment / Instrumentation

  • Point-of-Sale Terminals

  • Medical Equipment

  • Notebooks / Desktops / Servers

  • Computer Peripherals

  • Battery
