1500 W Zener TVS — 20.5 V standoff, AEC-Q101
The 1.5SMC24AHM3/H: Qualified to AEC-Q101, this part is suited for automotive and telecom applications where the 1500 W pulse rating absorbs load-dump and inductive clamp transients without cascading failure into downstream circuitry.
Pulse rating and clamping — what the numbers mean for the board
The 1500 W peak pulse power at 10/1000 µs is the device's rated energy-handling capacity — a 45.2 A surge through the 33.2 V clamp yields 1500 W peak, but the actual absorbed energy depends on the surge duration and the source impedance of the transient.
DO-214AB SMC package — footprint and board-fit
The SMC body (about 7.1 mm × 6.2 mm) fits standard pick-and-place; the tape-and-reel packaging supports high-volume reflow assembly with a 260 °C peak solder profile per JEDEC MSL level 1.
