Product details
Overview
ESD5484FCT5G from onsemi is a bidirectional ESD protection diode in a WLCSP2 package, designed for I/O line protection in portable electronics. It features a 5.0 V stand-off voltage, clamping voltage of 10.3 V at 3 A (IEC61000−4−2), <1 ns response time, and 35 pF typical capacitance - enabling robust electrostatic discharge suppression in space-constrained interfaces such as USB 2.0 and audio jacks.
For engineers reviewing the ESD5484FCT5G datasheet, pinout, applications, or equivalent options, key selection criteria include clamping performance under ±30 kV contact ESD, low leakage (<0.1 µA @ 5.0 V), IEC61000−4−2 Level 4 compliance, and compatibility with fine-pitch 0.36 mm pitch PCB layouts.
Technical Context
The ESD5484FCT5G implements a bidirectional silicon avalanche diode structure optimized for fast transient suppression without parasitic turn-on in normal operation. Its low 35 pF capacitance and sub-1 ns response ensure signal integrity preservation on high-speed data lines up to 480 Mbps.
Designed for placement directly at connector-level I/O pins, it operates within −55°C to +150°C junction temperature range and meets MSL 1 reflow requirements (260°C peak). The device delivers 30 kV air/30 kV contact ESD immunity per IEC61000−4−2 Level 4 while maintaining <0.1 µA reverse leakage at rated VRWM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage | 5.0 V - Maximum continuous operating voltage before conduction begins; ensures no interference with 5 V logic or USB signaling. |
| Clamping Voltage | 10.3 V @ 3 A - Peak voltage seen by protected IC during 8 kV contact ESD event; limits stress on downstream transceivers. |
| Capacitance | 35 pF - Low enough to avoid signal degradation on USB 2.0 and audio paths; measured at 1 MHz, 0 V bias. |
| Response Time | <1 ns - Enables suppression before ESD pulse energy couples into sensitive circuitry. |
| ESD Rating | ±30 kV contact / ±30 kV air - Full IEC61000−4−2 Level 4 compliance; exceeds system-level pass thresholds. |
| Leakage Current | 0.1 µA @ 5.0 V - Minimizes standby power loss and avoids false triggering in battery-powered devices. |
| Package Size | 0.60 mm × 0.30 mm × 0.30 mm - Ultra-compact WLCSP2 footprint ideal for mobile front-panel interfaces. |
Pinout & Package
ESD5484FCT5G uses the WLCSP2 (Wafer-Level Chip-Scale Package) with two terminals: anode and cathode. The package has no leads; solder balls are located on the bottom surface aligned to a 0.36 mm pitch. Marking "B" identifies the device variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | ESD current sink terminal | Connected to ground plane; conducts transient current away from protected line during positive ESD events. |
| 2 (Anode) | ESD current source terminal | Connected to I/O line; provides low-impedance path to ground for negative ESD transients via bidirectional avalanche action. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or differential lines (e.g., USB D+/D−, audio stereo) without polarity constraints. |
| 0.6 mm × 0.3 mm footprint | Reduces PCB area by >50% vs. 0201 discrete diodes; fits within tight spacing near micro-USB or SIM card connectors. |
| IEC61000−4−4 Level 4 EFT immunity | Withstands 40 A surge pulses (5/50 ns) - protects against electrical fast transients induced by relay switching or motor commutation. |
| Pb-free, Halogen-free, RoHS-compliant | Meets global environmental regulations and supports lead-free reflow profiles up to 260°C peak temperature. |
| MSL 1 rating | Allows unlimited floor life and eliminates bake-out requirements prior to assembly - reduces manufacturing overhead. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR | 0.65 mm × 0.35 mm DFN-2 package; 12 V clamping @ 3 A; 12 pF capacitance | Lower capacitance suits USB 3.0/MIPI D-PHY; higher clamping voltage increases protected IC stress margin | Select when lower capacitance is critical and system can tolerate higher clamping voltage |
| ESD9X5.0ST5G | SOD-523 package (1.2 mm × 0.8 mm); 12.5 V clamping @ 3 A; 45 pF capacitance | Larger footprint eases manual rework but limits ultra-dense layouts; higher leakage (1 µA) | Choose for prototyping or cost-sensitive designs where board space is less constrained |
Compared with TPD2E001DRYR and ESD9X5.0ST5G, the ESD5484FCT5G offers the smallest footprint (0.6 × 0.3 mm) and lowest clamping voltage (10.3 V) among these three, making it optimal for production-grade mobile I/O protection where PCB real estate and voltage headroom are simultaneously constrained.

FAQ
What is the maximum working voltage supported by ESD5484FCT5G?
The ESD5484FCT5G has a working peak reverse voltage (VRWM) of 5.0 V, meaning it can safely operate on DC or signal lines with continuous voltages up to this level without conducting. This makes ESD5484FCT5G suitable for protecting 3.3 V and 5 V I/O rails, including USB 2.0 data lines and audio codec interfaces, while remaining non-intrusive during normal operation.
Does ESD5484FCT5G require external biasing or control signals?
No, ESD5484FCT5G is a passive bidirectional avalanche diode and requires no external power, biasing, or control signals. It functions solely through its intrinsic PN junction characteristics - conducting only during overvoltage transients exceeding its breakdown threshold. This passive behavior ensures zero design overhead and full transparency to signal integrity in ESD5484FCT5G deployments.
Can ESD5484FCT5G be used for both positive and negative ESD events?
Yes, ESD5484FCT5G is explicitly designed as a bidirectional ESD protection device. Its symmetrical avalanche structure allows it to clamp both positive and negative ESD transients equally - verified by identical ±30 kV contact/air ratings per IEC61000−4−2. This enables single-device protection of AC-coupled or differential lines without polarity concerns in ESD5484FCT5G implementations.
What is the thermal resistance of ESD5484FCT5G and how does it affect reliability?
The ESD5484FCT5G has a junction-to-ambient thermal resistance (RJA) of 400°C/W on FR-5 board. While ESD events are nanosecond-scale and thermally insignificant, this RJA value supports safe operation under continuous conditions - especially important if the device experiences sustained leakage or fault currents. Its 150°C max junction temperature and MSL 1 rating further ensure long-term reliability in ESD5484FCT5G-equipped consumer electronics.
Is ESD5484FCT5G compatible with standard SMT reflow processes?
Yes, ESD5484FCT5G is qualified for Pb-free reflow with a maximum solder temperature of 260°C (10-second duration) and meets MSL 1 requirements - meaning it can be stored indefinitely at ambient conditions without baking. Its WLCSP2 package is compatible with Type 4 solder paste and 0.1 mm stencil thickness, supporting high-yield assembly in automated SMT lines using ESD5484FCT5G.
