The reverse standoff is 16 V typ, meaning the TVS sits idle below that voltage and only conducts when a surge pushes it above the 17.8 V minimum breakdown. At 57.7 A peak pulse current the clamping element survives the event without going short, so downstream circuits stay isolated. With a single unidirectional channel the part handles one polarity only — it does not float-bias or protect a bidirectional AC rail. The DO-214AB (SMC) package is the standard J-bend footprint — it reflow-solders directly to the board and the cathodic band marks the polarity stripe. The strip packaging variant means it ships in cut tape or loose form factor rather than on a reel; for production pick-and-place confirm the reel option is also available if your line requires it. Junction temperature is rated to 150 °C, which gives headroom above the 85 °C typical board ambient for consumer or light industrial enclosures — the part survives the thermal swing without derating below the rated peak pulse. ## What the ratings do not cover The 1.5SMCJ16A is listed as not rated for power-line protection, which means the 16 V standoff is a signal-level or low-power rail rating, not a 220/240 V mains-clamp application. Matching the correct TVS to the right voltage domain — signal line vs. mains bus — is where this spec matters most for BOM fit. ## Active sourcing posture Diotec Semiconductor lists this part as Active in production.","metaTitle":"1.5SMCJ16A TVS Diode, 16V standoff, 26V clamp, Diotec","metaDescription":"Diotec Semiconductor 1.5SMCJ16A unidirectional TVS diode, 16V standoff, 26V clamping, 1.5 kW peak pulse, SMC package.
