Product details

What the voltage and current ratings mean for protection

The 1.5SMC6.8A BK PBFREE: That 10.5 V ceiling is what the downstream circuitry actually survives.

DO-214AB SMC footprint and field-rework reality

The DO-214AB (SMC) package is the standard SMC footprint — it reflows cleanly on a standard profile and mates with common hot-air rework tooling if a board swap or rework is needed in the field. The SMC suffix on the supplier device package field confirms the standard 2.8 mm body width and the cathode-band orientation the datasheet specifies.

Temperature range and protection role

One unidirectional channel means this part clamps a single polarity — the reverse standoff of 5.8 V sets the DC working voltage the protected rail can sit at continuously without the TVS conducting. It is a general-purpose part with no dedicated power-line protection flag, so verify the 5.8 V standoff matches your rail nominal before committing.

Active lifecycle — what sourcing looks like

Sourced to order through independent distribution against your BOM quantity; availability and current lead time confirmed at RFQ.

Frequently asked questions

Is there a pin-compatible alternative to this TVS in the same SMC package?

The 1.5SMC series is a widely cloned industry footprint, so parts with the same 6.8 V standoff voltage in the DO-214AB SMC package are potential alternatives — but confirm the breakdown tolerance and peak pulse rating match your protection window before swapping, as the vendor-specific clamping characteristic can vary.
