Product details

Surge protection in a DO-214AB footprint

The 1.5SMC510A-E3/57T: The 1.5SMC510A-/57T is a 1500 W (1.5 kW) Zener-type transient voltage suppressor from Vishay's TransZorb series, packaged in a DO-214AB (SMC) surface-mount case.

Protection window and temperature range

With a minimum breakdown voltage of 485 V, the device starts conducting just above the 434 V standoff — the protected rail never sees more than 51 V of overshoot before the avalanche region engages. The 698 V clamping ceiling means downstream components rated for 700 V or higher survive the full rated surge without secondary breakdown. The single unidirectional channel is cathode-marked; the anode connects to ground.

Vishay has marked the 1.5SMC510A-/57T as obsolete. Replacement sourcing runs through independent distribution — quantities are lot-specific and confirmed at RFQ. The DO-214AB footprint is standard across the 1.5SMC family, so a parametric substitute from the same series or a competing brand may fit the same board pad.

Frequently asked questions

Where can I buy the 1.5SMC510A-/57T?

The part is obsolete and sourced through independent distribution channels.

What compliance documentation does Vishay provide for 1.5SMC510A-/57T?

The device carries the standard Vishay RoHS and REACH compliance documentation for the TransZorb series. No UL or IEC certification is listed in the available records — verify with the factory datasheet or your compliance team for the specific regulatory filing needed.
