The 482V clamp is the ceiling the downstream components see — if your circuit's absolute max rating is below that, this part won't protect it. ## Package and field-replaceability — DO-201 axial, through-hole Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE350A R0G is a through-hole part. The axial leads make it a straightforward swap on a board — no hot-air station, no reflow profile. Polarity is marked by the cathode band; orientation is obvious enough to get right with a multimeter in the field.","metaTitle":"1.5KE350A R0G TVS Diode, 300V Standoff, 1500W Peak, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE350A R0G Zener TVS, 300V reverse standoff, 482V clamp, 1500W peak pulse, DO-201 axial.
