At the full 3.8A peak pulse current, the clamp holds at 414V maximum, protecting downstream silicon from overvoltage. The DO-201AA axial package (also known as DO-27) is a through-hole form factor, easily hand-soldered or wave-soldered into a PCB or terminal block. No pin-compatible second-source or successor is listed, but the 1.5KE family is widely cross-referenced across TVS manufacturers.","metaTitle":"1.5KE300A A0G TVS Diode, 1500W, 256V, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE300A A0G Zener TVS, 1500W peak pulse, 256V standoff, 414V clamp, DO-201 axial.
