Product details

What this Zener TVS protects against

The 1N6146US: It clamps transients at 21V maximum when the surge current reaches 71.4A, with a reverse standoff voltage of 11.4V — meaning it stays off the rail below that DC level and only conducts during an overvoltage event. The SQ-MELF package (C case) is a surface-mount hermetic cavity designed for high-reliability applications.

Clamping voltage and surge current — sizing the protection margin

For a 12V rail, the 11.4V standoff leaves 9.6V of headroom before the diode starts conducting — enough margin for normal ripple without nuisance triggering.

The base product number 1N6146 covers a family of voltage options; the US suffix denotes the SQ-MELF surface-mount package. Sourced per RFQ — confirm lead time and pricing against your BOM quantity at quote time.
