1500W peak pulse — what it means for circuit protection
The 1.5KE33A-T: The 28.2 V reverse standoff voltage means it stays transparent on a 24 V rail, only conducting when the line exceeds the 31.4 V minimum breakdown threshold.
Through-hole DO-201 — board integration
Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE33A-T mounts through-hole and suits point-to-point wiring or PCB layouts where a soldered axial body is preferred over surface-mount. The single unidirectional channel protects one signal or power rail per device.
Temperature range and general-purpose use
No power line protection — intended for signal and low-voltage DC rail transient suppression, not AC mains.
