This 119V window gives the protected circuit a defined trigger point while limiting the let-through voltage to a safe level for downstream silicon rated at 200V or higher. The 4.8A peak pulse current rating at the 10/1000µs waveform is the current the diode can sink while clamping at 328V — useful for estimating surge capability into a given load impedance. ## DO-201 axial package and rework reality Housed in a DO-201AA (DO-27) axial-lead through-hole package, this part is built for high-surge energy dissipation. The large body and thick leads handle the thermal pulse of a 1.5kW transient without cracking the junction — something smaller SMD packages struggle with. For rework, the axial leads are easy to extract from a plated through-hole with a solder sucker or wick; just avoid overheating the body above 260°C for more than 10 seconds. ## Active production and sourcing posture Taiwan Semiconductor lists the 1.5KE220A R0G as Active.","metaTitle":"1.5KE220A R0G TVS Diode, 1500W, 185V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE220A R0G Zener TVS, 1500W peak pulse, 185V reverse standoff, 328V clamping, DO-201 axial.
