Product details

Transient protection specs — what the numbers mean

The 1.5SMCJ7.0C: The 7V reverse standoff is the maximum rail the diode blocks in normal operation — any voltage above this starts to crowd the breakdown region, but the part stays off until the transient pushes it past 7.8V minimum breakdown. That 6.3V overdrive above standoff is the clamping headroom that absorbs the transient energy and dumps it into the die.

Sourcing posture

The part is listed as Active under Diotec Semiconductor, which means new production is available through the standard franchised supply chain. Strip packaging is the reel-free format that some distributors hold as bulk cut-tape or factory-wound reel; confirm the exact delivery format against your pick-and-place tooling before committing to a BOM quantity. Sourced to order through independent distribution with availability and lead time confirmed at RFQ.

Frequently asked questions

What package does 1.5SMCJ7.0C use and is it rework-friendly?

The part ships in the DO-214AB (SMC) package, a common industry footprint that most hot-air rework stations handle without custom profiles. The strip packaging format indicates the standard Pb-free matte-tin finish compatible with reflow and hand rework alike.

What voltage does 1.5SMCJ7.0C actually clamp at during a surge?

The breakdown minimum is 7.8V, so the part transitions from blocking to clamping somewhere in that window depending on the surge amplitude — the 13.3V figure is the ceiling a downstream IC sees at full peak current.
