Product details

Transient protection threshold chain

The 1.5SMC18A V7G: That 25.5 V ceiling is what the downstream silicon sees — a 12 V or 15 V rail protected by this part survives a surge that would otherwise punch through a regulator or logic supply pin.

Power rating and waveform context

The 60 A peak pulse current at that waveform tells you the diode can absorb a substantial energy pulse without failing short; for shorter transients (8/20 µs, common in ESD or lightning surge testing), the peak current capability is higher, though the datasheet curve governs the derating.

Frequently asked questions

What package does 1.5SMC18A V7G use?
