The bulk packaging suits low-volume production and prototyping; the axial leads handle the thermal cycling of soldering without the stress concentration of a surface-mount joint.","metaTitle":"1.5KE51AHB0G Taiwan Semiconductor, 1500W Zener TVS, DO-201","metaDescription":"Active 1.5KE51AHB0G Zener TVS diode, 1500W peak pulse, 43.6V standoff, AEC-Q101 automotive grade.
