The axial leads make it easy to retrofit into existing designs or prototype on a breadboard. ## Obsolete — sourcing through independent channels Vishay lists this part as obsolete. Because this is a through-hole TVS with a standard DO-201AA footprint, a functional replacement from another manufacturer (same 1500 W rating, similar standoff and clamp voltages) can be sourced and cross-referenced at quote time if the original code is unavailable.","metaTitle":"1.5KE300CA-E3/51 TVS Diode, 1500W, 414V Clamp, DO-201AA","metaDescription":"Vishay 1.5KE300CA-E3/51 bidirectional TVS, 1500W peak pulse, 256V standoff, 414V clamp.
