Peak pulse power and clamping for 12V rails
The 1.5KE12CA B0G: It clamps transients at 16.7V maximum when the surge current hits 94A, protecting a 12V nominal rail from overvoltage events like inductive kickback or lightning-induced surges.
Reverse standoff and breakdown thresholds
Reverse standoff voltage is 10.2V typical — the diode stays high-impedance below this level, so it won't load a 12V bus during normal operation. Breakdown starts at 11.4V minimum, giving a narrow guard band before the clamp engages. The bidirectional single-channel design (one device) protects both polarities, which simplifies BOM count on AC-coupled or floating signal lines.
Through-hole package and temperature range
Housed in a DO-201AA (DO-27) axial-lead package, it's hand-solderable and fits standard through-hole layouts — no reflow profile needed, just a soldering iron and a pair of cutters.
