HSP061-2M6

The STMicroelectronics HSP061-2M6 is a steering (rail-to-rail) TVS diode designed for ESD protection in high-speed data line applications. It features a reverse standoff voltage of 3V and provides 2 unidirectional channels. Typical capacitance is 0.6pF measured at frequencies from 200MHz to 3GHz, making it suitable for high-speed signal integrity. Power line protection is integrated, and the device is housed in a compact 6-UFDFN package with a surface mount 6-uQFN (1.45x1) supplier device package. The operating junction temperature range spans -40°C to 150°C. Specific applications include Ethernet and HDMI interfaces. The device is RoHS3 compliant (unverified) with MSL 1 and REACH unaffected statuses (unverified).

The package measures 1.45mm x 1.0mm, enabling space-constrained PCB designs. The low capacitance ensures minimal signal distortion for high-frequency data lines. As a steering diode array, it directs ESD currents away from protected circuits while maintaining low leakage. It is a bidirectional protection element for differential signal pairs.

Design engineers should consider the junction temperature range and the low capacitance when integrating into high-speed digital interfaces. The surface mount package is suitable for automated assembly processes. The device provides robust ESD protection without compromising signal quality on Ethernet or HDMI lines.
