This is a steering (rail-to-rail) TVS diode array — it clamps transients to the supply rails rather than to a fixed voltage, making it a clean fit for high-speed data lines where low capacitance and fast response matter. The 3.3 V reverse standoff matches common 3.3 V logic rails directly; the typical clamp voltage is 10 V at the peak pulse current rating of 1 A (8/20 µs waveform).
Four unidirectional channels in one SC-74 package
Four unidirectional channels let one IC protect up to four signal lines, reducing component count on the board. The SC-74 (SOT-457) package is a compact 6-lead footprint — confirm the pad layout matches your assembly house's stencil aperture for the 0.95 mm pitch. Power line protection is supported, though the primary application is signal-line ESD clamping.
Sourcing and packaging options
The TR variant is the standard production reel for pick-and-place; CT suits prototype or low-volume builds. Surface-mount mounting — no through-hole variant exists for this order code. Current pricing and stock levels are confirmed at quote time. Submit an RFQ with your target quantity and preferred packaging (TR or CT) to receive a firm lead time and price.
