The 8.55V reverse standoff means it stays transparent on a 5V or 12V rail, only clamping when the transient exceeds the 9.5V minimum breakdown threshold. ## Clamping voltage and pulse current — what they mean for rail protection 14.5V clamping at 104.8A means the diode holds the transient below 14.5V even at full pulse current — a 12V rail with a 15V abs-max downstream regulator stays safe. The 9.5V min breakdown gives a 1V guard band above the 8.55V standoff — enough to avoid nuisance clamping from normal rail ripple or load transients. ## Active production — sourcing posture The DO-201 package is a standard axial-lead form factor that multiple foundries can supply, so second-source options exist within the 1.5KE family for identical electrical specs.","metaTitle":"1.5KE10CA Littelfuse TVS Diode, 1500W, 14.5V Clamp","metaDescription":"Littelfuse 1.5KE10CA bidirectional Zener TVS diode, 1500W peak pulse power, 14.5V clamping voltage, DO-201 package.
