Package and board integration
Housed in a DO-201AA (DO-27) axial-lead package with the supplier device code DO-201, the 1.5KE68CA R0G is a through-hole part suited for point-of-entry protection on power supply boards, telecom line cards, or industrial control panels where the axial form factor allows manual or wave-solder assembly. The operating junction temperature range spans -55°C to +175°C, covering both cold-start environments and the elevated ambient inside an enclosed power supply. This is a single bidirectional channel — a single device protects both polarities on a balanced line, eliminating the need for two back-to-back unidirectional diodes.
