The 103V clamp at 14.6A peak pulse current means the protected circuit sees no more than 103V across the terminals during a surge — the margin between the rail's normal peak and the clamp determines the headroom for downstream components. Operating temperature spans -65°C to 175°C junction — the full military-grade range. The 175°C TJ ceiling allows the part to absorb repetitive pulses without derating the peak power, as long as the average junction temperature stays below the absolute maximum. ## Obsolete — sourcing through independent channels Littelfuse lists the 1.5KE75ARL4G as obsolete. No official successor is recorded — the Mosorb™ series has been phased out.","metaTitle":"1.5KE75ARL4G Littelfuse Mosorb™ TVS, 1500W, 103V Clamp","metaDescription":"1.5KE75ARL4G Littelfuse Mosorb™ Zener TVS, 1500W peak pulse, 103V clamp, DO-201AD.
