Product details
Overview
ESD7484NCTAG from onsemi is a monolithic 4-line ESD protection diode optimized for HDMI, IEEE 1394, USB2.0, and high-speed video interfaces. It delivers ±15 kV IEC61000-4-2 Level 4 protection, 1.6–1.75 pF line-to-GND capacitance, 0.8 pF I/O-to-I/O capacitance, and 5.3 GHz cutoff frequency to preserve signal integrity up to 3.2 Gb/s. Its role is front-end transient suppression at connector-level I/O paths.
For engineers reviewing the ESD7484NCTAG datasheet, pinout, applications, or equivalent options, key selection criteria include ultra-low interline capacitance, flow-through layout compatibility with HDMI Type-C routing, clamping voltage under 8 kV TLP, and WLCSP10 footprint constraints in space-constrained mobile and portable designs.
Technical Context
The ESD7484NCTAG integrates five bidirectional ESD protection channels (four differential pairs + shared GND) in a single WLCSP10 die. Its flow-through bump layout minimizes stub length and maintains impedance continuity across all signal paths - critical for preserving HDMI 1.4 eye diagrams at 3.4 Gb/s.
It operates as a passive clamp using low-capacitance PN junctions, with breakdown voltage ≥6 V (Ir = 1 mA), leakage ≤100 nA at 3 V, and clamping voltage characterized via TLP up to 16 A. No bias voltage or enable control is required - it functions transparently in-circuit.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±15 kV air/contact discharge per IEC61000-4-2 Level 4 - protects external pins against worst-case human-body ESD events |
| Cline | 1.6–1.75 pF (I/O-to-GND @ 1 MHz) - enables clean HDMI 1.4/2.0 signal transmission without measurable eye closure |
| CI/O−I/O | 0.8 pF (differential pair coupling) - prevents crosstalk-induced jitter in adjacent high-speed lanes |
| Cutoff Frequency | 5.3 GHz - ensures minimal insertion loss and phase distortion up to 3.2 Gb/s data rates |
| VBR | 6–9 V (at 1 mA) - triggers clamping before downstream HDMI transceivers reach absolute maximum ratings |
| Peak Pulse Power | 70 W (8/20 µs) - sustains multiple ESD strikes without degradation in portable device lifecycles |
Pinout & Package
ESD7484NCTAG uses a 10-bump WLCSP (Wafer-Level Chip-Scale Package), Case 567DE, measuring 1.6 mm × 1.1 mm × 0.615 mm with 0.4 mm pitch. The flow-through layout aligns input and output bumps on opposite edges to minimize trace discontinuity.

| D3 | DIN_2− | Input cathode for second differential data lane (e.g., HDMI Data1−) |
| F3 | DOUT_2− | Output anode for second differential data lane |
| B2 | GND | Common ground reference for all four protection channels |
| E2 | GND | Second ground bump - reduces ground inductance and improves clamping symmetry |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD7481NCTAG | 3-line configuration (6 bumps), lower capacitance (1.3 pF line-to-GND), same WLCSP10 package | Suitable only for 3-lane interfaces (e.g., USB3.0 TX/RX/GND); lacks fourth differential channel | Select when protecting fewer than four high-speed lanes and tighter capacitance budget (<1.4 pF) is required |
| ESD7384MUTAG | 8-line, SOT-563 package (2.1 × 1.35 mm), higher Cline (2.5 pF), ±12 kV ESD rating | Designed for cost-sensitive industrial HDMI receivers; larger footprint and lower bandwidth (3.5 GHz) | Choose for non-mobile applications where PCB area is available and 3.5 Gb/s max data rate suffices |
Compared with ESD7484NCTAG, ESD7481NCTAG offers reduced capacitance but fewer protected lanes, while ESD7384MUTAG provides higher channel count in a larger package with relaxed bandwidth - making ESD7484NCTAG optimal for compact, high-data-rate mobile HDMI/1394 designs requiring exact 4-lane coverage.

FAQ
What is the primary circuit role of the ESD7484NCTAG in an HDMI design?
The ESD7484NCTAG serves as a front-end bidirectional ESD clamp on HDMI differential data and clock lanes. It sits between the HDMI Type-C connector and the source/sink IC, diverting ESD transients to ground before they reach sensitive transceiver circuitry. Its flow-through WLCSP10 layout ensures minimal impact on signal integrity - a critical requirement for ESD7484NCTAG deployment in 3.2 Gb/s HDMI 1.4/2.0 systems.
Does the ESD7484NCTAG require any external bias or control signals to operate?
No, the ESD7484NCTAG is a passive, unidirectional/bidirectional clamping diode array that operates without bias, enable pins, or external components. It relies on intrinsic PN junction behavior to conduct only during overvoltage events. This zero-power, always-on functionality makes ESD7484NCTAG ideal for battery-powered devices and simplifies layout - no routing or decoupling is needed beyond its GND connections.
How does the 0.8 pF I/O-to-I/O capacitance of the ESD7484NCTAG affect HDMI signal performance?
The 0.8 pF I/O-to-I/O capacitance of the ESD7484NCTAG directly limits crosstalk between adjacent differential lanes - a major contributor to deterministic jitter in HDMI 1.4/2.0 links. At 3.2 Gb/s, this value keeps inter-lane coupling below −35 dB, preserving eye opening and ensuring HDMI compliance mask margin. That specific 0.8 pF value is measured and guaranteed in the ESD7484NCTAG datasheet under 1 MHz, 30 mV conditions.
Can the ESD7484NCTAG be used for USB3.0 SuperSpeed differential pairs?
No, the ESD7484NCTAG is not rated or characterized for USB3.0 (5 Gbps) operation. Its 5.3 GHz cutoff frequency and 1.75 pF line-to-GND capacitance are validated only up to 3.2 Gb/s (HDMI 1.4/2.0, IEEE 1394b, USB2.0). For USB3.0, onsemi specifies dedicated parts like the ESD7504MUTAG. Using ESD7484NCTAG on USB3.0 lanes may cause excessive insertion loss and fail USB-IF compliance testing.
What is the thermal limit for continuous operation of the ESD7484NCTAG?
The ESD7484NCTAG has a maximum junction temperature (TJ) of 125°C and a storage temperature range of −55°C to +150°C. It is not intended for continuous power dissipation - its Absolute Maximum Ratings define only transient stress limits (e.g., 70 W peak pulse power). Under normal signal conditions, ESD7484NCTAG self-heats negligibly (<0.1°C rise) due to leakage current ≤100 nA at 3 V, making thermal derating unnecessary in typical HDMI/1394 applications.
