At that clamping voltage the device handles 64.7 A of peak pulse current — the energy is absorbed by the silicon junction, not shunted to ground through an external capacitor. For a 24 V nominal automotive bus, the 14 V standoff is too low; this part is sized for 12 V or 14 V rails where the transient must be clamped before it reaches downstream electronics. The DO-214AA (SMB) package is a standard surface-mount footprint shared across many TVS families. The bidirectional construction clamps both polarities with a single device, saving board space compared to two unidirectional diodes in anti-series. ## Active lifecycle — no last-time-buy pressure The product status is Active. For a BOM that already uses this part, the supply channel is straightforward: quoted to order against the line quantity, with availability confirmed at RFQ.","metaTitle":"Bourns 1.5SMBJ14CA TVS Diode, 1500W, Bidirectional, DO-214AA","metaDescription":"Bourns 1.5SMBJ14CA bidirectional Zener TVS, 1500W peak pulse, 14V standoff, AEC-Q101 automotive grade.

A pin-compatible alternative would be another 1.5SMBJ part with the same package and bidirectional configuration, but with a different standoff voltage — for example, the 1.5SMBJ12CA for a 12 V rail or the 1.5SMBJ16CA for a 16 V rail. The exact replacement depends on the protected voltage rail."},{"question":"What compliance documentation does Bourns Inc. provide for 1.5SMBJ14CA?","answer":"Bourns provides RoHS and REACH compliance documentation for the 1.5SMBJ series.
