Breakdown voltage min is 44.7V, and the clamping voltage max at Ipp is 64.8V — the downstream silicon must survive that peak without secondary breakdown. The unidirectional Zener construction means the cathode band orients the TVS for positive-rail clamping; reverse polarity protection requires a separate diode. ## Through-hole axial footprint Housed in a DO-201AA / DO-27 axial-lead package, supplier device package DO-201. Through-hole mounting with 0.100-inch lead spacing — compatible with standard perforated boards and wave-solder profiles. The Tape & Box packaging suits hand-insertion or axial-lead forming machines; no reel for auto-insertion. No power-line protection — this is a transient suppressor for signal or low-power supply rails, not a mains-side MOV replacement.","metaTitle":"1.5KE47AHA0G TVS Diode, 1500W, 40.2V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE47AHA0G Zener TVS, 1500W peak pulse, 40.2V reverse standoff, AEC-Q101 automotive, DO-201 axial.

This is the maximum continuous DC voltage the TVS can sit across without conducting. It protects 12V and 24V automotive buses with margin — the TVS remains in standby until a surge drives the rail above 44.7V breakdown."},{"question":"What compliance documentation does Taiwan Semiconductor provide for 1.5KE47AHA0G?","answer":"The part carries AEC-Q101 automotive qualification.
