1500W bidirectional Zener TVS — what the ratings mean for your rail
The 1.5KE15CA-T: The 12.8V reverse standoff voltage means it sits across a 12V rail without conducting in normal operation; the 14.3V minimum breakdown triggers clamping when the rail exceeds that threshold, and the 21.2V maximum clamping voltage at 71A peak pulse current defines the worst-case voltage the downstream circuitry sees during a surge event.
DO-201 axial package — board-fit note
Through-hole DO-201AA (DO-27) axial package — the lead spacing and body diameter match the standard 0.4-inch hole pitch on a prototype board or production PCB.
