For a 12 V bus, this keeps the transient well below the 20–30 V abs-max of most downstream regulators and logic. The -55°C to +175°C operating junction temperature range covers both cold-crank starts and engine-bay heat soak — the 175°C ceiling gives margin above the 150°C typical for automotive TVS devices. ## Package and mounting for through-hole assembly Housed in a DO-201AA / DO-27 axial-lead package, the 1.5KE11CAHE3_B/C is a through-hole device that solders into a 0.052-inch (1.32 mm) diameter hole on a standard PCB or terminal board. The axial leads handle the thermal cycling of wave-solder and hand-solder rework without cracking the glass passivation.","metaTitle":"1.5KE11CAHE3_B/C Vishay TVS, 1500W, 9.4V Standoff","metaDescription":"Vishay 1.5KE11CAHE3_B/C TransZorb TVS, 1500W peak pulse, 9.4V standoff, bidirectional, AEC-Q101.
