Clamping and power ratings for transient protection
The 1.5KE170CA R0G: With a peak pulse current rating of 6.7A, this part handles moderate surge events on AC or DC power rails, signal lines, and general-purpose board-level protection where bidirectional clamping is needed.
Package and thermal environment
Housed in a DO-201AA / DO-27 axial-lead package, the 1.5KE170CA R0G is a through-hole device suited for point-to-point wiring or PCB mounting where the lead bend radius and hole diameter follow the package drawing. The DO-201 body dissipates the 1500W pulse without requiring a heatsink — the axial leads conduct the transient heat into the board copper.
