1500 W peak pulse — the clamping voltage is the number that matters
The 1.5SMC24A R7G: That 33.2 V clamp is the figure a downstream regulator or IC must survive — if your 24 V bus sees a surge, this diode clips it before the silicon behind it lets go.
Active production — no end-of-life pressure on this BOM line
Taiwan Semiconductor lists the 1.5SMC24A R7G as Active. For a TVS that sits across a 24 V rail in a general-purpose power supply or industrial control board, that means you can spec it into a new design without worrying about a forced migration mid-production.
DO-214AB footprint — surface-mount, no lead-forming needed
The 1.5SMC24A R7G ships in Tape & Reel, so it feeds straight into a pick-and-place line. No power line protection (it is a unidirectional Zener TVS, not a bidirectional or steering-diode array), so keep it on the DC side of the rectifier.
