Can they at least clamp and handle much higher peak power than axial parts? Last edited: Apr 29, 2019

They have usually 10W upwards. May there are some legacy types. Short time peak power depends on the die size, not the case.

Is continuous power dissipation rating indicative of a zeners die size?
