Product details

1500 W peak pulse — what it means on the line

The 1.5SMC47A TR13 PBFREE: This is a 1500 W (1.5 kW) Zener TVS in a DO-214AB SMC package, rated for a single unidirectional channel. For a 36 V or 40 V supply bus, this gives you a solid guard band without nuisance clamping on normal ripple.

Package and board-fit for field replacement

DO-214AB (SMC) is a standard surface-mount package — 0.315 inch body length, JEDEC-registered footprint. The wide leads make it manageable with a hot-air station or even a soldering iron with a chisel tip if you pre-tin the pads. No hidden thermal pad underneath, so rework is straightforward. The wide margin means derating at high ambient is less aggressive than with a 125°C-rated part.
