This means a 24 V bus or a 18 V regulated supply sees the diode as an open circuit until a transient pushes the line above 20.9 V; the clamp then holds the spike to 30.6 V, protecting downstream silicon rated for, say, 36 V abs-max. ## DO-201 axial package and board integration The DO-201AA (DO-27) axial-lead package is a through-hole form factor with a body diameter of about 5.3 mm and a lead diameter of 1.3 mm. It mounts into a 1.1 mm hole on a standard PCB or terminal block. The axial leads carry the full 51 A surge current — the trace width feeding each lead should be sized for that peak current, not the DC load. The package is rated for junction temperatures from -55 °C to 175 °C, covering industrial and automotive under-hood ambient ranges.","metaTitle":"1.5KE22A R0G TVS Diode, 1500W, 18.8V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE22A R0G Zener TVS, 1500W peak pulse, 30.6V clamp at 51A, DO-201 axial.
