The 1.5SMCJ16A-AQ: Selecting a TVS with adequate standoff above the normal rail voltage is the primary sizing move; the clamping voltage is what determines whether the protected load survives the event. The 16V reverse standoff sits above the nominal 12V automotive rail — it stays inactive during normal operation and activates only when a load-dump or inductive transient raises the line above the breakdown threshold of 17.8V minimum.

It is a unidirectional Zener-type TVS (transient voltage suppressor) diode rated 1500W peak pulse at the standard 10/1000 µs surge waveform. The "SMCJ" type designation is the industry naming convention for a 1500W unidirectional TVS in the DO-214AB (SMC) package.
