1500 W peak pulse in a DO-214AB footprint
The 1.5SMC11CA_R1_00001: It clamps at 15.6 V max when the surge current hits 96 A, with a reverse standoff of 9.4 V — the rail voltage below which the diode stays off and the protected circuit sees no leakage. The breakdown window starts at 10.5 V minimum, so a 12 V DC bus or a 9 V regulated rail sits safely below the trigger threshold. Bidirectional construction means a single device handles positive and negative transients — no need to pair two unidirectional diodes back-to-back on a bipolar line.
At 96 A peak pulse current (10/1000 µs waveform), the clamping voltage rises to 15.6 V max. That 15.6 V ceiling is what the downstream ICs see during the surge — a 12 V-rated capacitor or a 16 V-rated MOSFET has margin, but a 10 V-rated part does not. The 9.4 V standoff means the diode draws negligible current below that level, so it does not load the signal or power rail during normal operation. The 1500 W peak pulse rating is the product of clamping voltage and peak current at the test waveform. For a shorter pulse (8/20 µs, common in ESD testing), the device can handle a higher peak current — the 10/1000 µs rating is the conservative figure for longer-duration surges like those from inductive load switching or lightning-induced transients on outdoor cabling.
Package and reel — board-fit and inventory planning
Housed in a DO-214AB (SMC) package, the device measures roughly 7.1 mm x 6.2 mm with a seated height under 2.6 mm — a standard footprint for 1500 W-class TVS diodes. The surface-mount body suits reflow assembly; the large copper tab on the cathode side (for unidirectional variants) doubles as a thermal path, though for this bidirectional part both terminals carry the same current. Supplied on Tape & Reel (Cut Tape also available per the listing), the reel format feeds pick-and-place machines without a reel change for medium-volume runs. Store the reels dry — the DO-214AB body is not moisture-sensitive per JEDEC Level 1, but the carrier tape can absorb humidity in long-term storage.
