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.","metaTitle":"1.5SMC43A R7G TVS Diode, 1500W, 36.8V Standoff, DO-214AB","metaDescription":"Taiwan Semiconductor 1.5SMC43A R7G Zener TVS, 1500W peak pulse, 36.8V reverse standoff, 59.3V clamp at 26A.
