1500 W peak pulse — what the clamp rating means for your rail
The 1.5KE33CA B0G: The 28.2 V reverse standoff means it sits across a 24 V nominal rail without conducting leakage; the 31.4 V minimum breakdown ensures the avalanche triggers before the protected circuitry sees damaging overvoltage. The bidirectional channel handles symmetrical clamping — positive or negative transients are clamped to the same magnitude. This suits AC-coupled signal lines or DC rails where reverse polarity is a risk.
Through-hole DO-201 — board-fit and temperature range
Housed in a DO-201AA (DO-27) axial-lead package, the device is through-hole mounted. Marked as General Purpose application and without power-line protection features, it is intended for signal and low-voltage DC rail transient suppression rather than mains AC clamping.
