This is a Zener-type TVS — no power-line protection feature, intended for signal and low-power supply clamping. ## Obsolete — sourcing through independent channels Vishay lists the 1.5KE30A/54 as Obsolete. No official successor order code is recorded. The DO-201AA footprint is common across the TransZorb family, so a functional replacement from the same series with the same standoff voltage exists, but pin-compatibility is not guaranteed without a board-level check. ## Clamping and temperature envelope Breakdown occurs at 28.5 V minimum, clamping at 41.4 V maximum across the 36.2 A peak pulse current. The junction temperature range spans -55°C to +175°C — suitable for industrial and telecom environments where the ambient stays within the derating curve for the 1500 W rating.","metaTitle":"Vishay 1.5KE30A/54 TransZorb TVS, 1500W, 25.6V Standoff","metaDescription":"Obsolete Vishay 1.5KE30A/54 TransZorb TVS diode, 1500W peak pulse, 25.6V reverse standoff, DO-201AA.
