1.5 kW bidirectional transient suppressor for 5 V rails
It delivers 1.5 kW of peak pulse power per the 10/1000 µs waveform, with a reverse standoff voltage of 5.8 V and a minimum breakdown of 6.45 V. Clamping is specified at 13.4 V maximum at the peak pulse current of 746 A (8/20 µs waveform). This is a general-purpose protection diode for equipment that sees surge events — think industrial control I/O, telecom line cards, or DC power bus clamps where a single bidirectional device replaces two unidirectional parts in anti-series.
Rated for the full industrial temperature span
The junction temperature range runs from -55°C to 150°C, which covers the full industrial and automotive under-hood envelope without derating the pulse power. That 150°C TJ max is the ceiling for junction temperature during the surge event, not just steady-state operation. For a board that lives in an engine bay or an outdoor cabinet, this part keeps its clamping spec across the temperature extremes where some commercial-grade suppressors start to leak or shift breakdown voltage.
DO-214AB SMC — a rework-friendly footprint
Housed in the DO-214AB SMC package, this is a surface-mount device with a generous body that handles the 1.5 kW pulse without needing a through-hole lead. The SMC footprint is large enough to hand-rework with hot air — the pad area gives good thermal mass, so the part doesn't cook during removal.
The base product number is SM15T6V8, so the CA suffix confirms the bidirectional polarity — keep that in mind when ordering to avoid pulling the unidirectional SM15T6V8A by mistake.
