500W bidirectional Zener TVS in SQ-MELF – 20.9V breakdown threshold
It is housed in a surface-mount SQ-MELF B package, supplied on tape and reel for automated assembly, and operates over a -55°C to 175°C junction temperature range — suitable for industrial, automotive, and military-grade environments where wide thermal margins are required.
16.7V reverse standoff – clamping at 30.5V protects 12V/15V rails
With a reverse standoff voltage of 16.7V, this diode sits above typical 12V and 15V supply rails, meaning it stays off during normal operation and only conducts during an overvoltage event. 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.
