The unidirectional design (single channel) clamps positive transients only; for bidirectional protection on AC or bipolar rails, a different ordering code from the same 1.5KE family is needed. ## Through-hole DO-201 package for high-reliability assembly The tape-and-reel packaging option supports automated insertion for volume production, though the axial form factor requires a compatible feeder or hand-placement for low volumes.","metaTitle":"1.5KE56AH Taiwan Semiconductor Zener TVS, 1500W, DO-201","metaDescription":"1.5KE56AH Zener TVS diode, 1500W peak pulse power, 47.8V standoff, AEC-Q101 automotive grade, DO-201 axial.
