With a reverse standoff voltage of 170V and a clamping voltage of 275V at 1.8A peak pulse current, it protects downstream semiconductors from surges up to 500W peak pulse power. The bidirectional configuration makes it suitable for AC signal lines or DC rails where polarity reversal is possible. Typical applications include general-purpose power supplies, industrial controls, and telecom equipment.
Breakdown voltage and clamping performance
Minimum breakdown voltage is 189V, which means the device starts conducting at that threshold. The 275V maximum clamping voltage defines the peak voltage the load sees during a 10/1000µs surge—critical for selecting downstream components with adequate voltage rating.
