The reverse standoff voltage is 185 V, meaning the diode stays off below that DC rail level and only starts conducting when the transient pushes above the 209 V minimum breakdown threshold. ## DO-201 axial-lead — a through-hole footprint that survives rework The package is DO-201AA (also known as DO-27), an axial-lead through-hole format. The supplier device package is DO-201. ## Unidirectional — one channel for DC rail clamping This is a single-channel unidirectional TVS. It clamps positive transients above the breakdown voltage while blocking reverse polarity — the right choice for a DC power rail (24 V, 48 V, or 120 VDC systems) where the normal operating voltage stays below 185 V. No power line protection is claimed (the part is not designed for AC mains), so it fits secondary-side or low-voltage DC bus protection.","metaTitle":"1.5KE220A B0G TVS Diode, 1500W, 185V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE220A B0G Zener TVS diode, 1500W peak pulse, 185V standoff, 328V clamp.
