1500 W bidirectional TVS for 9.4 V rails
The 1.5SMC11CAHM3/H: It clamps transients on a 9.4 V nominal rail — the reverse standoff voltage — and can handle a peak pulse power of 1500 W (1.5 kW) for a 10/1000 µs waveform. At the clamping voltage of 15.6 V, the diode conducts a peak pulse current of 96.2 A. That current-handling capacity, combined with the 1500 W rating, tells you this part is sized for moderate-energy transients — load-dump events on automotive power buses or surge-coupled noise on telecom lines — not for direct lightning-strike energy.
AEC-Q101 and the automotive temperature envelope
The DO-214AB (SMC) package is a standard surface-mount footprint for TVS diodes in this power class.
