The 548 V clamping voltage at 2.8 A peak pulse current is the ceiling the diode holds the transient to — downstream components see no more than that, which is the number to check against the absolute maximum ratings of the ICs or modules on the rail. The DO-201AA (DO-27) axial package is a standard leaded form factor that fits existing PCB layouts for the 1.5KE family. ## Sourcing and compliance No power line protection (the diode is not designed for AC mains primary-side clamping), but for DC rails, signal lines, and secondary-side transient suppression at 342 V working voltage, this is a standard fit.","metaTitle":"YAGEO 1.5KE400A/B TVS Diode, 1.5kW, 342V Standoff","metaDescription":"YAGEO 1.5KE400A/B Zener TVS diode, 1500W peak pulse power, 342V reverse standoff, DO-201 package.
