Protection against both ESD and high-current, long-duration surge events: high surge protection levels, excellent ESD protection, small form factor.
Product list
While Infineon has a strong focus on ESD specific devices, it also has solutions for another major TVS category i.e., high current surge. In this case, a long duration high current event is the issue, not the nearly instantaneous super high voltage ESD event. To handle these longer current pulses, a different kind of part is required.
The list below is taken from Infineon's current product table; click a type code for the product page, or the PDF link for the data sheet.
- High surge protection levels
- Excellent ESD protection
- Small form factor
- Excellent quality and reliability
