• Wayon Power TVS Products protect electronic circuit against transient and overvoltage threats such as surge up to 10kA and 15kW respectively, including automotive diodes, high reliability TVS diodes and NR-TVS.

• Automotive diodes are RoHS and UL listed while also meet AEC-Q101 requirement.

• The use of silicon technology in the NR-TVS products offer lower clamping voltage.

• SMA, SMB, SMC, SOD-123 and DFN package demensions are included, among which the size of DFN package is 3.3 mm×3.3 mm×1mm, especially the thickness is superior to traditional package.
