The single unidirectional channel handles positive-going transients; for bidirectional protection a second device or a different series is needed. ## Pulse current and temperature envelope Rated 2.8A peak pulse current at the 10/1000µs test condition — this is the current that produces the 548V clamping voltage across the device. The junction temperature range spans -55°C to 175°C, so the diode survives both cold-start and hot-bench environments common in industrial and telecom gear. The DO-201 axial body suits through-hole assembly and allows manual replacement in rework or field repair.","metaTitle":"1.5KE400A A0G TVS Diode, 1500W, 342V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE400A A0G Zener TVS diode, 1500W peak pulse power, 342V reverse standoff, 548V clamping.
