The axial leads also suit point-to-point wiring in prototype or repair work. ## Obsolete — sourcing through independent channels Vishay lists this part as obsolete. For a new-design replacement, a functionally equivalent TVS in the same DO-201AA footprint with a 43.6 V standoff and 1500 W rating would need to be qualified against the original's clamping curve.","metaTitle":"1.5KE51AHE3/51 Vishay TVS Diode, 1500W, 43.6V Standoff","metaDescription":"Obsolete Vishay 1.5KE51AHE3/51 TransZorb TVS diode, 1500W peak pulse, 43.6V standoff, AEC-Q101.
