Clamping at 258V maximum at the 5.8A peak pulse current means the downstream silicon sees no more than 258V across the transient. The 1500W peak pulse rating (10/1000µs) defines the energy the device absorbs in a single surge — a longer or higher-energy pulse requires a higher-rated part. The operating junction temperature range spans -55°C to +175°C, covering outdoor telecom cabinets and industrial enclosures where ambient heat plus self-heating from repetitive surges must stay within the die's thermal limit. ## DO-201AA axial package — board-fit note Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE180C-/54 is a through-hole device. The lead spacing and body diameter match the standard 1.5KE footprint — a drop-in replacement for any 1.5KE-series bidirectional TVS in the same package. The bidirectional construction (single die, two back-to-back junctions) means polarity is irrelevant — install it either way across the rail.","metaTitle":"Vishay 1.5KE180C-E3/54 TransZorb TVS, 1.5kW, 258V Clamp","metaDescription":"Obsolete Vishay 1.5KE180C-E3/54 bidirectional TVS diode. 1500W peak pulse power, 162V breakdown, DO-201AA axial.
