8.4.3 Zero Derating

Unlike traditional diodes, the TVS0701 has zero derating of maximum power dissipation and ensures robust performance up to 125°C. Traditional TVS diodes lose up to 50% of their current carrying capability when at high temperatures, so a surge pulse above 85°C ambient can cause failures that are not seen at room temperature. The TVS0701 prevents this so the designer can see the surge protection regardless of temperature. Because of this, Flat-Clamp devices can provide robust protection against surge pulses that occur at high ambient temperatures, as shown in TI's TVS Surge Protection in High-Temperature Environments application report.
