Product details

30 V rail clamp with 600 W pulse rating

Its 33.3 V minimum breakdown voltage ensures the device starts clamping before the rail exceeds safe limits, while the 48.4 V maximum clamp at 12.4 A limits the let-through voltage during a surge. The 12.4 A peak pulse current gives the designer a hard limit for fuse coordination and trace width sizing.

Surface-mount DO-214AA (SMB) package with a standard footprint that reflows on a typical lead-free profile. The tape-and-reel delivery suits automated pick-and-place assembly.

The suffix indicates RoHS compliance and the lead-free finish, so no special handling or exemption paperwork is needed for EU or similar markets. We confirm current pricing and availability at quote time — no stock-holding claim, no deferred lead time.

Frequently asked questions

Is SMBJ30AE3/TR13 RoHS compliant?

Yes, the suffix in the order code denotes RoHS compliance and lead-free termination finish. No special exemption paperwork is required for EU or similar regulated markets.

What package does SMBJ30AE3/TR13 come in?

It is supplied in a DO-214AA (SMB) surface-mount package, delivered on tape and reel. The SMB footprint is common and reflows on standard lead-free profiles.

Is SMBJ30AE3/TR13 unidirectional or bidirectional?

It is a unidirectional Zener TVS, meaning it clamps only one polarity (positive relative to ground). For bidirectional protection on AC or bipolar rails, a different device is needed.

Can SMBJ30AE3/TR13 replace SMBJ30A?

The base electrical ratings (30 V standoff, 33.3 V breakdown, 48.4 V clamp) are identical between the SMBJ30A and the SMBJ30AE3/TR13. The suffix on this part confirms RoHS compliance and lead-free finish; the TR13 suffix indicates tape-and-reel packaging. If your existing BOM uses the SMBJ30A in a DO-214AA package, this is a drop-in replacement for lead-free assembly lines.
