Product details

500W bidirectional Zener TVS in SQ-MELF – 20.9V breakdown threshold

16.7V reverse standoff – clamping at 30.5V protects 12V/15V rails

The 30.5V clamping ceiling limits the voltage seen by downstream circuitry during a surge. The bidirectional configuration (single channel) means polarity does not matter — it clamps equally on positive and negative transients, simplifying layout on AC-coupled or bipolar signal lines.

Active production – tape & reel ordering code

If you need the same die in a different carrier, confirm the exact ordering code with your distributor.

Frequently asked questions

Can 1N6114AUS/TR replace the through-hole 1N6114A?

The 1N6114AUS/TR is the surface-mount SQ-MELF version of the 1N6114A. Electrical characteristics (breakdown, standoff, clamping, peak pulse power) are identical, but the package and footprint differ — the SQ-MELF requires a reflow solder profile and a different PCB land pattern than the through-hole part. If your board is designed for the through-hole variant, a direct drop-in replacement is not possible without layout changes.
