The bulk packaging means parts are loose in a bag or tube — no reel, so hand-insertion or tube-fed auto-insertion is the assembly path.","metaTitle":"1.5KE56AHB0G TVS Diode, 1.5kW, 77V Clamp, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE56AHB0G automotive TVS diode, 1.5kW peak pulse, 77V clamping, AEC-Q101, DO-201.
