The leads are stout enough to survive a few bend-and-straighten cycles if you're replacing one on a board with tight lead spacing. Pin 1 is the cathode band; orientation is unambiguous as long as the band is visible after soldering. The 1.5KE-HF series is the family; other breakdown voltages in the same package are available if the 47A variant is the fit.","metaTitle":"Comchip 1.5KE47A-HF TVS Diode, 1500W, DO-201","metaDescription":"1.5KE47A-HF Zener TVS diode, 1500W peak pulse, 40.2V standoff, 64.8V clamp.
