Two-channel clamp for data lines
The D5V0M2B3LP-7B is a Zener-type TVS from Diodes Incorporated, packing two bidirectional protection channels in a single X1-DFN1006-3 package — a three-lead DFN with a 1.0 mm × 0.6 mm footprint. It clamps a 5 V (max) reverse standoff rail to 14 V at the 12 A (8/20 µs) peak pulse current, absorbing up to 130 W of peak pulse power. The 28 pF line capacitance (measured at 1 MHz) keeps signal integrity intact on USB 2.0, HDMI, or other high-speed differential pairs — the low loading won't degrade edge rates on sub-480 Mbps busses.
Supply rail and temperature range
The device operates across -65°C to 150°C junction temperature, covering automotive under-hood and industrial outdoor enclosures without derating concerns.
