It clamps transients at 19.11 V max while conducting 26.13 A peak pulse current, making it a fit for protecting 9.9 V nominal rails in industrial or automotive environments. The single bidirectional channel means it can clamp both positive and negative surges on a single line — useful on AC-coupled signals or bipolar supply buses where polarity is not fixed. ## Breakdown and clamping margins Minimum breakdown voltage is 11.73 V, with a reverse standoff of 9.9 V. That leaves roughly 1.8 V of margin before the diode starts conducting leakage current — enough headroom for a 9 V rail with ±10 % tolerance without false triggering. The 19.11 V clamping voltage at 26.13 A peak pulse current defines the maximum voltage the protected circuit sees during a surge event. For a 12 V-rated downstream IC, this clamp is safe; for a 5 V logic rail, it is not — select a lower-voltage part in the same family. ## Active production and sourcing posture The axial through-hole package (B, Axial) is a standard leaded form factor that stores well on tape or in bulk bins — no moisture sensitivity level to track, no dry-bag requirement.","metaTitle":"1N6109 Zener TVS Diode - 500W, 9.9V Standoff","metaDescription":"1N6109 bidirectional Zener TVS diode from Microchip Technology. 500W peak pulse power, 9.9V reverse standoff, 11.73V breakdown.
