Product details

8V rail clamp with 600W headroom

Breakdown starts at 8.89V minimum, clamping at 15V maximum with a 40A peak pulse current — so an 8V supply sees the clamp engage well before the downstream regulator's absolute max.

DO-214AA SMB — bench-fit and rework note

Housed in the DO-214AA (SMB) surface-mount package, the part is a direct footprint match for the common SMBJ series. Supplied on tape & reel (TR suffix), it feeds straight into a pick-and-place line. No power line protection feature here — this is a signal-rail or low-side supply clamp, not a mains-side suppressor.

Active production — no EOL pressure

Microchip lists the SMBJ8.0E3/TR13 as Active. The base product number SMBJ8.0 spans multiple voltage variants in the same DO-214AA package, so the line is stable.

Frequently asked questions

Is SMBJ8.0E3/TR13 obsolete?

No — the product status is Active. No end-of-life or last-time-buy has been issued by Microchip.

What is the closest pin-compatible alternative to SMBJ8.0E3/TR13?

Within the same SMBJ family, the SMBJ8.0A is a direct electrical and footprint match — same 8V standoff, same DO-214AA package. The '' suffix on this part indicates RoHS compliance and Microchip's specific qualification flow; the SMBJ8.0A may carry different environmental certification. Confirm the BOM's RoHS requirement before swapping.
