1500W bidirectional transient suppressor for 214V rails
The 1.5KE250CA R0G: Breakdown occurs between 237V minimum and the clamp at 344V, with a peak pulse current capacity of 4.5A under the 10/1000µs test condition. The bidirectional construction means a single part protects both polarities — no need to orient the diode on the board, which simplifies placement in AC-coupled or floating signal lines.
DO-201 axial package and temperature range
Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE250CA R0G mounts through-hole — the leads handle the surge current without the trace-width constraints of a surface-mount pad. No power line protection feature is built in — this is a general-purpose transient suppressor for signal, DC bus, or low-voltage AC lines, not a primary AC mains protector. The base product number is 1.5KE250, and the R0G suffix indicates tape-and-reel packaging for automated insertion.
