The 175 °C maximum junction temperature gives headroom under the hood on a hot day. ## Automotive qualification and temperature reach AEC-Q101 qualification means this diode passed the full automotive stress battery — high-temperature reverse bias, temperature cycling, and ESD robustness — so it belongs in an engine-bay ECU or a transmission controller without a second thought. Through-hole DO-201AA (DO-27 axial) package makes it a hand-solderable choice for prototype runs or rework, and the axial leads fit standard PCB hole patterns. ## Sourcing and compliance reality The base product number is 1.5KE120, so the same die and package are shared across the 1.5KE family. No pin-compatible second-source is listed, but the TransZorb® series is a standard footprint — any DO-201AA TVS with matching standoff and clamping voltage will fit the same board holes.","metaTitle":"1.5KE120AHE3_A/D Vishay TVS, 1.5kW 102V Standoff","metaDescription":"Vishay 1.5KE120AHE3_A/D automotive TVS diode, 1500W peak pulse, 102V reverse standoff, AEC-Q101 qualified.
