Active production — a straightforward BOM fit
The 1.5SMC130CA: The 111 V reverse standoff voltage and 179 V clamping point mean this part protects 100–110 VDC rails from overvoltage transients, clamping the surge before it reaches the downstream converter or load.
Protection thresholds and what they mean on the rail
The bidirectional channel lets you install this part across a DC rail without polarity concern — it clamps equally in both directions, which simplifies inventory on a line that uses both positive and negative supplies.
Package and temperature range for board-level integration
Housed in a DO-214AB (SMC) package, the 1.5SMC130CA reflows with standard lead-free profiles and mates with the common SMCJ footprint. The -55°C to 150°C junction temperature range covers the full industrial temperature envelope — no derating worry in an outdoor cabinet or an engine-bay ECU that sees 105°C ambient.
