1.5 kW clamping decision for 160 V rails
The SMCJ160CA-13: With a 160 V reverse standoff voltage, it clamps transients at 259 V maximum — the figure that decides whether the downstream silicon survives a surge event. Breakdown occurs at a minimum of 178 V, so the part stays transparent below that threshold and starts conducting only when the line exceeds it. The 5.8 A peak pulse current rating at the 10/1000 µs pulse defines the energy it can absorb in a single event — useful for estimating margin against the actual transient energy on the rail.
Housed in the DO-214AB (SMC) package, the SMCJ160CA-13 is a surface-mount footprint shared across the SMCJ family. The supplier device package is also SMC — no extra adapter or landing pattern variation needed if you already qualify this case size. The -13 suffix indicates Tape & Reel packaging, which is the standard feed format for pick-and-place assembly lines. No tube or tray variant is listed for this order code.
The 150°C TJ max means the clamping performance is specified up to that junction temperature — derating the peak pulse power above 25°C is standard practice per the device class. No power line protection flag is set — this is a signal-rail or low-voltage bus protector, not a mains-side suppressor.
Sourcing and compliance posture
General-purpose application classification means no special automotive or medical qualification is claimed on this listing — confirm your own compliance requirements (RoHS, REACH) at RFQ time through the supply chain documentation package.
