1500W peak pulse at 34A — clamping voltage defines the protection ceiling
The 1.5KE33CA-AQ: The reverse standoff voltage of 28.2V means it sits across a nominal 24V DC bus and remains transparent until a transient exceeds the breakdown threshold of 31.4V min. The through-hole axial package (DO-201AD footprint) is a legacy form factor still widely used in power distribution boxes, battery junction units, and high-reliability industrial power supplies where vibration resistance and manual inspection are preferred over SMT.
Active lifecycle, AEC-Q101 documentation, and sourcing posture
As an AEC-Q101 qualified part, the manufacturer provides the standard compliance documentation package: RoHS and REACH declarations, PPAP (Production Part Approval Process) data upon request, and the AEC-Q101 test report covering the qualification lot.
