1500W peak pulse power, bidirectional Zener clamp
The 1N6143A is a 1500W (1.5kW) peak pulse power Zener TVS diode from Microchip Technology, designed to clamp transients on a single bidirectional channel. It handles a peak pulse current of 96.2A under the 10/1000µs waveform, with a clamping voltage of 15.6V at that current. The 8.4V reverse standoff means it sits transparently on a 5V or 3.3V rail, only conducting when the line exceeds that threshold. This is a through-hole axial part (B, Axial package), so it is a field-swappable component — no hot-air station needed.
Active production, through-hole axial package
The through-hole axial package (B, Axial) is a standard footprint that fits existing board layouts without redesign. Sourced per RFQ against your BOM quantity.
