The 219 V clamp ensures downstream semiconductors rated for 250 V or higher survive the event. ## Package and temperature envelope Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE160A-/51 mounts through hole on a standard 0.100-inch pitch board. The axial body suits point-to-point wiring or PCB insertion where a surface-mount TVS would not survive the reflow profile. The junction temperature range spans -55°C to 175°C, covering military and industrial ambient extremes. Power derating above 25°C follows the standard TVS curve — at 175°C the device handles roughly 20% of the 1500 W rating, so thermal margin is essential for repetitive surge applications. ## Last Buy lifecycle and sourcing Vishay has flagged the 1.5KE160A-/51 as Last Buy — the manufacturer is no longer accepting new orders beyond the final production run. For a BOM that already qualifies this TVS, the Last Buy status means securing a lifetime buy lot or qualifying a functional equivalent before stock dries up. The 1.5KE series shares the same DO-201AA footprint and breakdown voltage range, so a parametric alternative from the same family is the natural cross-reference.","metaTitle":"Vishay 1.5KE160A-E3/51 TransZorb TVS, 1500W, DO-201AA","metaDescription":"Vishay 1.5KE160A-E3/51 TransZorb TVS diode, Zener type, 1500W peak pulse power, 136V standoff, DO-201AA axial.
