What this TVS diode protects and how it clamps
Single bidirectional channel means it clamps both polarities symmetrically — useful on AC lines or DC rails where reverse polarity is a risk. Breakdown voltage minimum is 144V, clamping max is 231V at 6.5A peak pulse current.
The base product number is SMCJ130, so future date-code lots will carry the same die and package.
