The 1500W rating at 10/1000µs is the peak-pulse power — the actual energy-handling capability depends on the pulse duration and duty cycle, but for the standard lightning-surge test waveform this part absorbs the full transient without secondary protection. ## Sourcing and traceability The bulk packaging (not tape-and-reel) is typical for through-hole power diodes — no reel fee, but the handling is manual at the pick-and-place level.","metaTitle":"TSC 1.5KE43AHB0G TVS Diode, 1.5kW, 36.8V Standoff","metaDescription":"Taiwan Semiconductor 1.5KE43AHB0G Zener TVS, AEC-Q101, 1500W peak pulse, 36.8V reverse standoff, 59.3V clamp.
