This temperature range suits avionics, downhole instrumentation, and military power supplies where commercial plastic packages would delaminate or degrade. ## Bidirectional channel — no polarity restrictions With a single bidirectional channel, the 1N6109AUS clamps both positive and negative transients symmetrically. This eliminates the need to orient the diode on the PCB, simplifying layout on AC-coupled signal lines or bipolar power buses.","metaTitle":"1N6109AUS Zener TVS – 500 W, 9.9 V, SQ-MELF","metaDescription":"1N6109AUS from Microchip: 500 W peak pulse power, 9.9 V reverse standoff, bidirectional Zener in hermetic SQ-MELF.
