64.6V breakdown, 500W peak pulse — bidirectional TVS for general-purpose protection
The 1N6126A is a bidirectional Zener TVS diode from Microchip Technology, rated for 500W peak pulse power per the 10/1000µs waveform. Its 64.6V minimum breakdown voltage and 97.1V maximum clamping voltage define the protection window for a 51.7V reverse standoff line — meaning the protected circuit must tolerate the clamp voltage without damage, and the TVS triggers before the line exceeds that ceiling. A single bidirectional channel clamps both polarities, which is useful on AC signal lines or bipolar supplies where two unidirectional diodes in series would add cost and PCB area. The 5.1A peak pulse current rating (10/1000µs) gives the surge-handling capacity for typical industrial transient events like inductive kickback or lightning-induced surges on long cable runs.
Active production — axial leaded package, wide temperature range
Microchip lists the 1N6126A as Active, so it remains a valid choice for new designs and production builds without end-of-life risk. The through-hole axial package (B, Axial) is a standard leaded format that suits point-to-point wiring, terminal blocks, or through-hole PCB assembly — no special reflow profile needed. The 175°C ceiling gives margin above the 150°C typical for many plastic-packaged TVS diodes.
