When a transient pushes the line above 8.89V (minimum breakdown), it starts conducting and holds the clamp at 15V max — that's the protection window you size your downstream circuitry to survive. Housed in a DO-214AC (SMA) surface-mount package, the same footprint as standard SOD-123W or SMB variants. The SMA body is large enough to hand-solder with a fine-tip iron or hot-air station without cooking the board — the cathode band is clearly marked, so orientation is straightforward under a loupe. If you are reworking a board that saw a transient event, the diode itself may have degraded — replace it rather than reusing it.

In reverse bias, it will read open until you exceed the breakdown voltage — do not apply more than 8.89V during a simple go/no-go check. A curve tracer or TVS tester is better for verifying the clamping characteristic."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/SMAJ8.0E3-TR13","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/SMAJ8.0E3-TR13 when reusing this data.
