Product details

10 V rail protection — clamping at 17 V, 37 A peak pulse

Its 11.1 V minimum breakdown voltage means it stays transparent during normal operation and starts conducting when the line rises above that threshold. The 17 V maximum clamping at 37 A (10/1000 µs waveform) is the ceiling your downstream circuitry must survive — that 600 W peak pulse power rating is the energy it can absorb in a single surge event without failing.

Temperature range and mounting — surface-mount, wide thermal margin

The SMB footprint is a standard two-pad surface-mount package — no through-hole, no heatsink tab. Reflow profile follows standard MSL 1 handling (no bake required before assembly if the moisture barrier bag is intact).

Frequently asked questions

What is the closest pin-compatible alternative to SMBJ10A-TR in this component family?

The SMBJ12A is the next higher standoff voltage in the same SMBJ TRANSIL™ family — same DO-214AA package, same 600 W peak pulse power rating, but with a 12 V reverse standoff and a 13.3 V minimum breakdown. If your rail is 12 V rather than 10 V, that is the direct sibling.
