Bidirectional Zener TVS — 1500W peak pulse, 11.1V standoff
The 1.5KE13CA B0G: The reverse standoff voltage is 11.1V, meaning the line voltage sits below this threshold during normal operation and the diode stays off. When a transient exceeds the minimum breakdown voltage of 12.4V, the device clamps at a maximum of 18.2V while shunting up to 86A of peak pulse current. For a 12V rail in a DC power bus or signal line, that clamp margin keeps downstream silicon within its safe operating area.
DO-201 axial package — through-hole for high-reliability or high-surge designs
Housed in a DO-201AA (DO-27) axial-lead through-hole package, the 1.5KE13CA B0G is suited for designs where surface-mount TVS diodes would struggle to dissipate the 1500W pulse without board-level thermal relief.
