Product details
Overview
ESD8111PFCT5G from onsemi is an ultra-low-capacitance bidirectional ESD protection diode in WLCSP2 (0.6 mm × 0.3 mm) package, designed for I/O-to-GND protection of high-speed data lines. It delivers 0.2 pF typical junction capacitance, 3.3 V reverse working voltage, and clamps to 8.0 V at 7.1 A peak pulse current-enabling robust ESD immunity up to ±30 kV (IEC 61000−4−2 contact) in USB 3.0/3.1 and MHL 2.0 interfaces.
For engineers reviewing the ESD8111PFCT5G datasheet, pinout, applications, or equivalent options, key selection criteria include sub-0.4 pF capacitance at 1 MHz, low 2.1 V holding voltage, ±30 kV IEC contact ESD rating, and side-wall isolated WLCSP2 footprint compatibility with high-density mobile PCB layouts.
Technical Context
The ESD8111PFCT5G employs a silicon avalanche diode structure optimized for fast response (<1 ns) and minimal signal distortion on differential high-speed buses. Its bidirectional clamping architecture ensures symmetrical protection for both positive and negative ESD transients without polarity dependence.
Designed specifically for side-wall isolation in 0201-scale WLCSP2 packaging, it achieves <0.4 pF capacitance while maintaining 3.3 V VRWM and 8.6 V max breakdown voltage-meeting stringent insertion loss requirements for 5 Gbps+ serial links per S21 measurements up to 10 GHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Capacitance (CJ) | 0.2 pF typ @ 0 V, 1 MHz - preserves signal integrity on USB 3.1 Gen 1 (5 Gbps) channels |
| Reverse Working Voltage (VRWM) | 3.3 V - matches standard I/O supply rails in mobile SoCs and USB PHYs |
| Clamping Voltage (VC) | 8.0 V @ 7.1 A (8/20 µs) - limits transient overvoltage below IC damage thresholds |
| ESD Rating (IEC 61000−4−2) | ±30 kV contact / ±30 kV air - exceeds Level 4 immunity for handheld device interfaces |
| Dynamic Resistance (RDYN) | 0.46 Ω - enables rapid energy dissipation with minimal voltage overshoot |
| Junction Temperature Range | −55 °C to +150 °C - supports operation in automotive infotainment and industrial edge devices |
Pinout & Package
ESD8111PFCT5G uses the WLCSP2 (Case 567AV) package: 0.6 mm × 0.3 mm, 0.27 mm pitch, side-wall isolated die-attach construction. This ultra-compact footprint minimizes parasitic inductance and enables placement directly at connector entry points.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | I/O Line Anode/Cathode | Bidirectional ESD path - connects to protected high-speed data line (e.g., USB D+, D−) |
| 2 | GND | Low-inductance ground return - requires direct connection to solid ground plane via shortest possible trace |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 0.2 pF typ ensures <−1 dB insertion loss at 5 GHz - critical for USB 3.1 Gen 1 eye diagram compliance |
| Side-wall isolation | Eliminates leakage paths between I/O and GND terminals in WLCSP2 - improves reliability under humidity and bias stress |
| Low clamping voltage | 8.0 V at 7.1 A prevents latch-up or gate oxide damage in 3.3 V interface ICs |
| Pb-free, RoHS-compliant | Meets IPC-J-STD-020 moisture sensitivity level 1 (MSL1) - supports standard reflow profiles without baking |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD8101FCT5G | Same family but DSN2 (01005) package; 0.2 pF capacitance; ±23 kV IEC contact rating | Larger 0.435 mm × 0.23 mm footprint; higher parasitic inductance limits use to ≤3 Gbps links | Select when board space allows larger package and ESD requirement is Level 3 (±23 kV) only |
| TPD2E007DRYR | Texas Instruments part in SOT-5X3; 0.75 pF typ; ±8 kV IEC contact; integrated 100 Ω series resistor | Higher capacitance restricts use to USB 2.0 or lower-speed interfaces; resistor adds signal attenuation | Choose only if system-level design requires built-in series termination and Level 2 ESD suffices |
Compared with ESD8111PFCT5G, ESD8101FCT5G offers identical electrical specs but less compact packaging and lower ESD rating, while TPD2E007DRYR trades capacitance and ESD performance for integrated resistive matching-making ESD8111PFCT5G optimal for 5 Gbps+ applications demanding maximum signal fidelity and highest immunity.

FAQ
What is the exact package type and dimensions of ESD8111PFCT5G?
ESD8111PFCT5G uses the WLCSP2 package (Case 567AV), measuring 0.6 mm × 0.3 mm with 0.27 mm pitch. It features side-wall isolation and a 2-terminal configuration. The package complies with JEDEC MO-254 standards and supports MSL1 handling per IPC-J-STD-020 without baking prior to reflow.
Does ESD8111PFCT5G support bidirectional ESD protection?
Yes, ESD8111PFCT5G provides symmetric bidirectional clamping between I/O and GND terminals. Its I-V curves (Figures 8 and 10 in the datasheet) confirm matched turn-on behavior for both polarities, enabling protection of AC-coupled differential signals like USB 3.1 without polarity constraints.
What is the maximum peak pulse current ESD8111PFCT5G can handle?
ESD8111PFCT5G is rated for 7.1 A peak pulse current under the 8/20 µs waveform condition, at which it clamps to 8.0 V. Under TLP testing, it sustains 16 A pulses with clamping voltage rising to 10 V-validating robustness against multiple ESD strikes per IEC 61000−4−2 Level 4 compliance.
How does the 0.2 pF capacitance of ESD8111PFCT5G impact USB 3.1 Gen 1 signal integrity?
The 0.2 pF typical junction capacitance of ESD8111PFCT5G introduces negligible loading on USB 3.1 Gen 1 (5 Gbps) differential pairs. Measured S21 insertion loss remains below −1 dB up to 5 GHz (Figure 4), preserving eye height and jitter margin-critical for passing USB-IF compliance testing without equalization overhead.
Is ESD8111PFCT5G compatible with lead-free reflow processes?
Yes, ESD8111PFCT5G is Pb-free, halogen-free, and RoHS-compliant. Its WLCSP2 package is qualified for standard lead-free reflow profiles (peak temperature 260 °C for 10 seconds), with MSL1 rating ensuring no moisture sensitivity concerns during assembly.
