Product details
Overview
ESD7108MUTAG from onsemi is an 8-line, 4-pair ultra-low-capacitance ESD protection diode array designed for high-speed differential data lines including V-by-One HS and LVDS. It features 0.25 pF max junction capacitance (I/O to GND), ±15 kV IEC 61000-4-2 contact/air ESD rating, and 5.0 V reverse working voltage, enabling signal integrity preservation in display interface applications.
For engineers reviewing the ESD7108MUTAG datasheet, pinout, applications, or equivalent options, key selection criteria include low-capacitance transient clamping for >3.7 GHz fundamental frequencies, flow-through routing compatibility with matched trace length requirements, and UDFN18 package integration into space-constrained LCD timing controller layouts.
Technical Context
The ESD7108MUTAG implements a monolithic silicon avalanche diode array with eight bidirectional I/O pins arranged as four differential pairs, each protected by back-to-back diodes referenced to common GND terminals. Its clamping behavior is characterized via TLP testing at ±8 A and ±16 A, delivering 14.5 V and 19.5 V max clamping voltages respectively.
Designed for impedance-critical interfaces, it maintains insertion loss below −0.175 dB at the 5.562 GHz third harmonic of V-by-One HS (3.71 GHz fundamental), confirming minimal signal degradation. The device requires only one GND connection for full functionality, with six dedicated GND pins (pins 3, 6, 9, 13, 15, 17) and four NC terminals (pins 12, 14, 16, 18).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Capacitance (I/O–GND) | 0.25 pF max - preserves signal integrity up to 5.56 GHz third harmonic in V-by-One HS links |
| ESD Rating (IEC 61000-4-2) | ±15 kV contact & air - meets Level 4 system-level ESD immunity without external shielding |
| Clamping Voltage (TLP) | 14.5 V @ ±8 A - limits transient overvoltage during fast ESD events on high-speed lanes |
| Reverse Working Voltage | 5.0 V - supports operation on 3.3 V and 5 V differential signaling buses |
| Breakdown Voltage | 5.5–8.5 V - ensures reliable turn-on before damage threshold of protected ICs |
| Junction Capacitance Match | 0.02 pF max difference - maintains skew control across differential pairs |
Pinout & Package
ESD7108MUTAG is housed in a 5.5 mm × 1.5 mm UDFN18 (Case 517BV) package with 0.5 mm pitch, exposed thermal pad, and coplanar terminals. Pin 1 is marked by chamfered corner; all N/C pins (12, 14, 16, 18) must remain unconnected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 7, 8, 10, 11 | I/O | Bidirectional ESD protection path for 4 differential pairs (A+, A−, B+, B−, etc.) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E05U06DQAR | 0.5 pF max capacitance; 5.5 V VRWM; 3.3 V logic-compatible clamping | Targeted for USB 2.0/3.0 and HDMI; higher capacitance limits use above 1.5 GHz | Preferred where lower clamping voltage is prioritized over RF bandwidth |

FAQ
What is the maximum operating junction temperature for ESD7108MUTAG?
The ESD7108MUTAG has a specified operating junction temperature range of −55°C to +125°C. This wide thermal envelope supports deployment in automotive cabin environments and industrial displays subject to ambient extremes. The device's thermal performance is enhanced by its UDFN18 package with exposed copper pad, which facilitates efficient heat dissipation to the PCB ground plane during repeated ESD events. Always verify board-level thermal design margins using the ESD7108MUTAG's power derating curve in the official datasheet.
Does ESD7108MUTAG require all six GND pins to be connected?
No-ESD7108MUTAG requires only a minimum of one GND connection (e.g., pin 3 or pin 6) for full functionality across all eight I/O lines. The six GND pins (3, 6, 9, 13, 15, 17) provide flexibility for PCB layout optimization and improved current sharing during multi-pin ESD strikes. However, connecting multiple GND pins lowers overall inductance and improves clamping consistency, especially in high-frequency applications like V-by-One HS. The ESD7108MUTAG datasheet explicitly confirms single-GND operability.
Can ESD7108MUTAG be used on PCIe Gen3 or USB 3.1 differential lanes?
ESD7108MUTAG is not recommended for PCIe Gen3 (8 GT/s) or USB 3.1 (10 Gbps) due to its 0.25 pF capacitance being optimized for V-by-One HS (3.71 GHz fundamental) and LVDS (< 1.5 Gbps). While its capacitance is low, its clamping response and layout constraints (flow-through routing, fixed 8-line pairing) do not align with the channel equalization, return loss, and crosstalk requirements of those protocols. For PCIe/USB 3.1, dedicated high-speed ESD arrays such as NUP4201MR6T1G or ESDALC6-1BM2 are better matched. ESD7108MUTAG remains ideal for display-specific differential interfaces.
What is the significance of the "MUTAG" suffix in ESD7108MUTAG?
The "MUTAG" suffix in ESD7108MUTAG denotes a specific packaging and marking variant: "MU" indicates the UDFN18 package (Case 517BV), "T" signifies tape-and-reel packaging (3000 units per reel), and "AG" identifies the Pb-free, RoHS-compliant construction with standard onsemi date coding. This ordering code distinguishes it from other variants like ESD7108MUTBG (different date code) or ESD7108MUTDG (alternate reel size). All ESD7108MUTAG units share identical electrical specifications and pinout per the ESD7108/D datasheet.
How does ESD7108MUTAG's TLP clamping performance compare to its DC breakdown rating?
ESD7108MUTAG exhibits a DC breakdown voltage (VBR) of 5.5–8.5 V at 1 mA, but its TLP-measured clamping voltage rises to 14.5 V at ±8 A and 19.5 V at ±16 A-reflecting dynamic impedance increase under fast transient conditions. This behavior is typical of silicon avalanche diodes and confirms that ESD7108MUTAG provides progressively stronger clamping as ESD current escalates, protecting downstream receivers without premature conduction during normal signal swings. The ESD7108MUTAG's TLP curve is validated per ANSI/ESD STM5.5.1, ensuring correlation with real-world 100 ns ESD events.
