Power Schottky diodes avalanche ratings specification

STMicroelectronics delivers a complete range of Power Schottky with explicit avalanche specification for precise matching design.
The avalanche rating temperature and pulse width derating curves ensure a precise match between the power
converter voltage spikes and the capability of the diodes.
That’s why this key information provides designers with the opportunity to choose between upgrading the efficiency by 2% or reducing the BOM (bill of material) cost by 2%.
The fundamental key benefit relies on the freedom for designers to choose between efficiency improvement cost saving.
