Transient Voltage Suppressors

ON Semiconductor has introduced five new electro-static discharge (ESD) suppression devices for today's most advanced interfaces. Patent pending design techniques and process technology enable these devices to deliver the industry's lowest capacitance and ESD clamping voltage, suitable for use with extremely high data rate interfaces and small geometry chipsets.

The ESD8000 transient voltage suppressor (TVS) series achieves maximum capacitance specification of 0.35 pF, and ESD clamping voltages down to 8 V at 16 amperes (A), equivalent to IEC61000-4-2 Level 4 8 kilovolts (kV) contact. The extremely low capacitance nearly eliminates any degradation to the data line signal integrity at data rates greater than 10 Gb/s, supporting emerging interfaces such as USB 3.0, USB 3.1, HDMI 2.0, and Thunderbolt.  The low clamping voltage improves protection of system level ESD testing as chipsets evolve into geometries below 20 nanometer (nm), making them more sensitive to transient voltage.

The four-line ESD8004 and ESD8104 can protect two pairs of voltage sensitive high speed data lines in the industry standard footprint of the 2.5 x 1 mm UDFN-10 package, making them suitable for the latest serial interface standards such as USB 3.0, HDMI 2.0, and eSATA.  The flow-through style package enables easy printed circuit board layout and the matched trace lengths necessary to maintain consistent impedance between high speed differential lines.

The ESD8008 integrates eight lines, or four differential pairs, into a single package for HDMI, DisplayPort, and V-by-One HS interfaces.

The six-line ESD8006 TVS is optimized for protecting the fastest interfaces operating at 10 Gb/s such as Thunderbolt and USB 3.1.  These devices have a capacitance of 0.25 pF and utilize single connect flow through routing packages which eliminates the "no connect" pin commonly found on other flow through packages, ensuring minimal parasitic impact to the data line and signal integrity.

The ESD8040 is designed specifically to provide a full function integrated ESD protection device for the HDMI interface and Display Port IOs.  This device optimizes pin placement and routing to provide 14 lines of protection required to serve all data, power, and control lines of the interface in an innovative, space saving package that still maintains single connect flow through routing on the high speed lines.  The 14 lines of fully integrated protection in a single package, combined with industry leading performance, make this an ideal solution to protect the challenging HDMI 2.0 interface.  The ESD8040 is also backwards compatible with HDMI 1.3 and 1.4.

The ESD8004 and ESD8104 are offered in Pb-free UDFN-10 packages and priced at $0.16 and $0.12 per unit in 3,000 unit quantities, while the ESD8040 is offered in Pb-free UDFN-18 packages and priced at $0.40 per unit in 3,000 unit quantities.  The ESD8006 and ESD8008 are offered in Pb-free UDFN-8 and UDFN-14 packages respectively and priced at $0.15 and $0.19 per unit in 3,000 unit quantities.
