Clamping window for a 24V rail
The 1.5KE24CA-G: Its reverse standoff voltage of 20.5V means it stays transparent on a 24V nominal bus, and it clamps transients to 33.2V maximum at the rated 45.18A peak pulse current. That clamping ceiling is the number the downstream silicon must survive. Single bidirectional channel protects both polarities from one axial-lead package — saves a second diode and a PCB hole pair in AC-coupled or bipolar supply lines.
DO-201 through-hole fit
Supplied in DO-201AA / DO-27 axial-lead form (DO-201 supplier device package). The through-hole lead diameter and 0.300-inch (7.62 mm) lead spacing are standard for this class; the board footprint matches the common 1.5KE series land pattern. Tape & Box (TB) packaging — not reel — so the pick-and-place feeder may need a tube or tray adapter.
Active lifecycle, no EOL flag
No official successor or second-source cross-reference is published. The part is a standard JEDEC-registered 1.5KE device; parametric equivalents exist from multiple manufacturers (Littlefuse, Vishay, ST) but pin-to-pin compatibility depends on the lead form and body length — confirm the PCB hole pattern against the DO-201 footprint before substituting.
