The through-hole body suits high-reliability point-to-point wiring or PCB mounting where the lead bend absorbs thermal cycling strain. Supplied in Tape & Box (TB) format for hand-insertion or low-volume automated lines. ## Breakdown and clamping performance Minimum breakdown voltage is 40.9 V, ensuring the diode starts conducting before the protected line reaches 41 V. The maximum clamping voltage of 59.3 V at 26 A peak pulse current gives the designer a hard ceiling — any transient below that energy is clamped without exceeding the TVS's 1500 W rating. No power-line protection feature (the device is intended for signal or low-side supply clamping, not AC mains).","metaTitle":"1.5KE43AHA0G TVS Diode, 1500W, AEC-Q101, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE43AHA0G Zener TVS, 1500W peak pulse, 36.8V standoff, AEC-Q101 qualified.
