Surge protection window and clamping behaviour
The 1.5KE7.5CA B0G: The reverse standoff voltage is 6.4V typical, with a minimum breakdown of 7.13V; clamping max at 139A peak pulse current is 11.3V. This means a 12V rail or a 5V signal line sees the clamp engage well below the downstream IC's abs-max rating, provided the surge energy stays within the 1500W envelope. The bidirectional channel (single device) handles both positive and negative transients without polarity concern — useful on AC-coupled data lines or bipolar power buses where a unidirectional part would need an external bridge.
Package and integration into a through-hole board
Housed in a DO-201AA / DO-27 axial leaded package (supplier device package DO-201), the part is a standard through-hole fit. The axial leads suit point-to-point wiring, terminal block termination, or PCB through-hole mounting with 0.040-inch diameter holes. No special reflow profile — hand-solder or wave-solder at typical 260°C peak.
The wide range also means the part can sit on a hot PCB near a regulator or processor without exceeding the die temperature limit.
