Its 23.1 V reverse standoff voltage means the protected DC rail must stay below that level during normal operation; the device starts conducting above the 25.7 V minimum breakdown threshold. ## Through-hole axial package and mounting Housed in a DO-201AA / DO-27 axial-lead package, this is a through-hole component — it requires a drilled PCB hole and wave or hand soldering, not reflow. ## Compliance and documentation Rated for general-purpose circuit protection — not certified to automotive AEC-Q101 or UL 1449 on the record; intended for DC signal and low-voltage power rail transient suppression, not AC mains.","metaTitle":"1.5KE27A-E3/54 Vishay TVS, 1500W, 23.1V Standoff, DO-201","metaDescription":"1.5KE27A-E3/54 Vishay TransZorb TVS diode, 1500W peak pulse, 23.1V reverse standoff, unidirectional, DO-201AA axial.
