This is the voltage the TVS forces the transient down to — a 40V nominal rail seeing a 100V surge gets clamped to 64.8V, which is below the typical 80V abs-max of common 40V-rated DC-DC converters and linear regulators. The 24A peak pulse current is the maximum the device can handle in the 10/1000µs test waveform without exceeding its 1500W power rating. The single-channel layout keeps the PCB footprint to two axial leads; the DO-201AA body is the standard through-hole package for this power class, and the lead spacing matches common 0.3-inch pitch layouts. ## Active production and sourcing posture The bulk package means parts ship loose in anti-static tubes or bags — no reel or tape for automated pick-and-place, consistent with the through-hole form factor. For high-volume builds, verify the lead-forming requirements match your wave-solder or selective-solder process.","metaTitle":"1.5KE47CAHB0G TVS Diode, 1.5kW, 40.2V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE47CAHB0G bidirectional TVS, 1500W peak pulse, AEC-Q101 automotive grade, 40.2V reverse standoff, DO-201 axial.

It certifies the 1.5KE47CAHB0G has passed stress tests including high-temperature reverse bias, temperature cycling, and humidity bias at 85°C/85% RH. This makes it suitable for under-hood, engine-bay, and other harsh automotive environments where temperature extremes and vibration are present."},{"question":"Is this a bidirectional or unidirectional TVS?","answer":"This is a bidirectional device.
