5V rail protection with 1500W surge capacity
Its 1500W peak pulse power rating (10/1000µs waveform) handles industrial surge events like IEC 61000-4-5 without sacrificing the compact DO-214AB footprint. With a reverse standoff voltage of 5V, the device stays transparent under normal operation, then breaks down at a minimum of 6.4V to clamp the line at 9.2V maximum. This margin protects 5V logic and transceiver ICs from overvoltage damage.
Bidirectional single-channel clamping
A single bidirectional channel protects both positive and negative transients on one line, eliminating the need for two unidirectional TVS diodes in series. This simplifies BOM count and PCB layout for differential signal pairs or power rails where polarity reversal is possible. The peak pulse current of 163A (10/1000µs) gives the designer a clear derating curve for shorter or longer pulse widths. At higher ambient temperatures, the power dissipation must be derated per the datasheet curve, but the 150°C junction rating allows operation in hot environments like outdoor telecom cabinets.
Active production, sourced per RFQ
Microchip lists it as current, and no direct successor or replacement has been announced. Sourcing is confirmed per RFQ — no stock-holding claim, but the supply chain is active and multi-source accessible.
