1500 W peak pulse — clamping the surge before it reaches the rail
The 1.5SMC43A R7G: At the clamping voltage of 59.3 V max, it handles a peak pulse current of 26 A — enough to shunt a 24 V or 36 V supply rail transient without the voltage rising above the downstream IC's abs-max rating. This leaves a 4.1 V window between the nominal rail and the avalanche threshold, avoiding false clamping on ripple or load transients within the design margin.
DO-214AB (SMC) — footprint and thermal path
Supplied in tape and reel (R7G suffix), the package is compatible with standard pick-and-place and reflow profiles. The reflow profile should follow JEDEC J-STD-020 for a moisture-sensitive device — the DO-214AB body typically requires a 260°C peak reflow with a 30-second TAL.
Active production — sourcing through authorized channels
For BOM positions requiring traceability, the active lifecycle means lot-date-code consistency is maintained through the authorized supply chain — the laser-etched marking on the SMC body should match the manufacturer's plant code and date format, a point to verify when sourcing from secondary channels.
