The Zener breakdown mechanism delivers a fast, well-defined clamping voltage with no snap-back — critical for protecting ECUs, sensors, and actuators on automotive power distribution buses. ## Package and thermal integration for through-hole assembly Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE56AHE3_A/C mounts through-hole on the PCB. The leaded format allows the body to sit above the board, improving convective cooling and simplifying visual inspection of the solder joint — a preference in automotive and industrial power stages where rework access matters. The operating junction temperature range spans -55°C to 175°C, covering the full automotive temperature envelope including under-hood soak-back. The 1500W peak pulse rating assumes the device starts at 25°C; derating is required at elevated ambient temperatures per the datasheet curve. ## Active lifecycle and sourcing posture The AEC-Q101 qualification documentation and RoHS/REACH compliance declarations accompany each shipment.","metaTitle":"1.5KE56AHE3_A/C Vishay TVS, 1500W, 47.8V Standoff","metaDescription":"Vishay 1.5KE56AHE3_A/C automotive TVS, 1500W peak pulse, 47.8V standoff, 77V clamp, AEC-Q101, DO-201AA.
