Vishay has marked the 1.5KE100CA-/51 as Obsolete. No official successor order code is recorded on the lifecycle entry. Because the TransZorb® series spans a wide parametric range, a functional replacement with the same package (DO-201AA) and similar clamping voltage may exist within the family, but no pin-compatible direct substitute is documented by Vishay for this specific order code. A board-level review of the clamping threshold and peak current requirement is advised before substituting. ## Clamping performance and application fit With a breakdown voltage minimum of 95 V and a clamping maximum of 137 V at 10.9 A peak pulse current, this TVS is sized for 85.5 V nominal rails — typical in 72 V telecom or 80 V industrial DC buses where the transient must be clamped before exceeding the downstream device's abs-max rating. Power line protection is not supported (the device lacks the low dynamic resistance needed for continuous AC mains clamping), so it is best applied on signal or DC power inputs rather than direct mains-side protection.","metaTitle":"1.5KE100CA-E3/51 Vishay TVS, 1500W Bidirectional, 85.5V","metaDescription":"1.5KE100CA-E3/51 Vishay TransZorb® bidirectional TVS, 1500W peak pulse, 85.5V standoff, DO-201AA.
