The single bidirectional channel means it handles both positive and negative surges on the same line, which simplifies layout for AC-coupled or floating signal lines. The axial through-hole package (B, Axial) is a legacy footprint — expect manual insertion or wave-solder assembly, not reflow. ## Temperature range and thermal reality At 175°C the leakage current through the Zener junction rises significantly — derate the peak pulse power per the datasheet curve above 25°C. In a 125°C ambient, the 500 W rating drops to roughly 250 W; plan the surge budget accordingly. ## Sourcing and production status The base product number is 1N6129, and the 'A' suffix indicates a tighter tolerance on breakdown voltage. Sourced per RFQ against your BOM quantity — no stock-holding claim, but the active status keeps the supply chain open through authorized distribution.","metaTitle":"1N6129A Zener TVS Diode – 500W, 69.2V Standoff, Axial","metaDescription":"1N6129A Zener TVS diode from Microchip Technology. 500W peak pulse, 69.2V reverse standoff, 125.1V clamping.
