Product details
Overview
ESD5102FCT5G from onsemi is a bi-directional dual-line ESD protection diode in DSN3 (0.73 × 0.25 mm) package, rated for ±15 kV IEC 61000−4−2 contact/air discharge, with 3.3 V reverse working voltage, 5.5 pF junction capacitance, and 6.5 V clamping voltage at 16 A TLP. It protects high-speed data lines in space-constrained portable electronics.
For engineers reviewing the ESD5102FCT5G datasheet, pinout, applications, or equivalent options, key selection criteria include low capacitance for USB 2.0/MIPI compatibility, sub-1 mm² footprint for wearable PCBs, IEC Level 4 compliance, and verified clamping performance under 8 kV contact ESD stress.
Technical Context
The ESD5102FCT5G integrates two independent bi-directional ESD protection paths in a single ultra-small DSN3 package, each rated for 3.3 V VRWM and designed to clamp transients within nanoseconds. Its low 5.5 pF capacitance ensures minimal signal distortion on high-frequency interfaces such as USB 2.0 and MIPI D-PHY.
It meets IEC 61000−4−2 Level 4 (±15 kV contact/air), with clamping voltage specified at 5.4 V (8 A TLP) and 6.5 V (16 A TLP), enabling robust protection without compromising signal integrity in portable device I/O ports.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±15 kV per IEC 61000−4−2 contact & air – enables full Level 4 system-level ESD compliance without external shielding |
| Reverse Working Voltage | 3.3 V – matches standard I/O rail voltage for USB, HDMI, and MIPI interfaces |
| Junction Capacitance | 5.5 pF at 0 V, 1 MHz – preserves signal rise time and insertion loss for ≤480 Mbps data rates |
| Clamping Voltage | 6.5 V at 16 A TLP – limits transient overvoltage below 7 V to protect 3.3 V logic inputs |
| Package | DSN3 (0.73 × 0.25 mm, 0.27 mm pitch) – fits in <0.2 mm² board area, ideal for smartwatch button or sensor flex traces |
| Operating Temperature | −55 °C to +125 °C – supports operation in extended ambient environments including wearable skin-contact zones |
Pinout & Package
ESD5102FCT5G uses the DSN3 (Case 152AW) ultra-miniature surface-mount package with two terminals: Pin 1 (I/O Line 1) and Pin 2 (I/O Line 2), sharing common GND internally via substrate connection. The device has no dedicated GND pin - ground return is through solder joint thermal pad and PCB copper pour.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | I/O Line 1 Anode/Cathode | Bi-directional ESD path for first protected signal line (e.g., USB D+) |
| Pin 2 | I/O Line 2 Anode/Cathode | Bi-directional ESD path for second protected signal line (e.g., USB D−) |
Key Features
| Feature | Design Value |
|---|---|
| Bi-directional dual-line protection | Single-device protection of differential pairs without polarity constraints or external biasing |
| Low 5.5 pF capacitance | Enables use on 480 Mbps USB 2.0 and MIPI D-PHY lanes without measurable eye diagram degradation |
| IEC 61000−4−2 Level 4 compliance | Validated ±15 kV contact/air survivability eliminates need for secondary board-level ESD mitigation |
| Pb-free, RoHS-compliant DSN3 package | 0.73 × 0.25 mm footprint supports automated placement in high-density wearable flex-rigid assemblies |
Applications
| Smartphone Front-Facing Camera Interface | Smartwatch Touch Sensor Bus |
|---|---|
Use Scenario: Protecting MIPI CSI-2 data lanes between image sensor and AP in thin bezel smartphones. IC Role / Device Role / Timing Role: ESD transient suppressor placed directly at connector/sensor pad to limit voltage excursion during handling or cable insertion. Use Value: 5.5 pF capacitance avoids signal integrity loss across 1–2 GHz bandwidth; ±15 kV rating ensures pass/fail reliability in drop-test and factory ESD audits. | Use Scenario: Shielding capacitive touch controller I²C lines from ESD events induced by finger contact on curved glass. IC Role / Device Role / Timing Role: Bi-directional clamping diode on SDA/SCL lines, located adjacent to touch IC to minimize loop inductance. Use Value: Sub-1 mm² DSN3 footprint allows placement within 0.3 mm of touch IC pins; 6.5 V clamping prevents latch-up in 1.8 V I²C receivers. |
| Wireless Earbud Charging Port | Fitness Tracker Heart Rate Sensor Flex |
Use Scenario: Safeguarding USB-C CC and VCONN lines against ESD during repeated plug insertion in compact earbud cases. IC Role / Device Role / Timing Role: Dual-line protector mounted at port entry point, routing CC and VCONN through separate internal paths. Use Value: 3.3 V VRWM aligns with USB-C specification; 5.4 V clamping at 8 A TLP ensures safe operation under 4 kV contact discharge per IEC Level 2 equivalence. | Use Scenario: Protecting photodiode amplifier inputs and LED drive lines in optical HRM modules bonded to stretchable elastomer substrates. IC Role / Device Role / Timing Role: Low-capacitance ESD clamp on analog front-end nodes exposed to user skin contact and environmental charge buildup. Use Value: −55 °C to +125 °C operating range accommodates body-worn thermal cycling; 0.23 mm height avoids interference with flex bending radius. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5Z3.3T5G | Single-line, same DSN2 package; 3.3 V VRWM, 5.5 pF, ±12 kV IEC rating | Limited to single-signal protection; requires two devices for differential pair coverage | Select when protecting isolated GPIO or reset lines where dual-line integration is unnecessary |
| CM1213A-03SR | Quad-line, SOT-563 package; 3.3 V VRWM, 12 pF typical, ±15 kV IEC rating | Larger 2.1 × 1.25 mm footprint; higher capacitance limits use to ≤100 Mbps interfaces | Prefer when consolidating four low-speed lines (e.g., UART + I²C) and board area is less constrained |
Compared with ESD5102FCT5G, ESD5Z3.3T5G offers lower cost per line but doubles component count and layout complexity for differential signals, while CM1213A-03SR provides greater channel density at the expense of bandwidth and footprint - making ESD5102FCT5G optimal for miniaturized high-speed differential interfaces.

FAQ
What is the maximum clamping voltage of the ESD5102FCT5G under IEC 61000−4−2 Level 4 stress?
The ESD5102FCT5G clamps to 6.5 V at 16 A TLP current, which corresponds to IEC 61000−4−2 Level 2 equivalent (±8 kV contact). While it is rated for ±15 kV Level 4, clamping voltage is not specified at that level - design margin must be verified using TLP curves in the ESD5102FCT5G datasheet Figure 6 and Figure 7.
Can the ESD5102FCT5G be used on USB 2.0 high-speed (480 Mbps) differential pairs?
Yes, the ESD5102FCT5G is qualified for USB 2.0 high-speed use due to its 5.5 pF junction capacitance and low clamping voltage. Measured S21 insertion loss (Figure 4) shows <−0.5 dB up to 500 MHz, confirming minimal impact on eye diagram integrity - provided layout maintains controlled impedance and minimizes stub length near the ESD5102FCT5G pads.
Does the ESD5102FCT5G require an external ground connection?
No, the ESD5102FCT5G does not have a dedicated ground pin. Its DSN3 package uses substrate-level grounding through the solder joint and underlying PCB copper pour. Proper thermal pad connection to a solid GND plane is essential for effective ESD current shunting and thermal dissipation during transient events.
What is the operating temperature range for the ESD5102FCT5G?
The ESD5102FCT5G operates from −55 °C to +125 °C, as defined in its Absolute Maximum Ratings table. This range supports deployment in wearable devices exposed to body heat and ambient temperature extremes, as well as industrial handheld tools operating in uncontrolled environments - all while maintaining specified clamping and leakage performance.
How does the ESD5102FCT5G compare to TVS diodes in terms of response time?
The ESD5102FCT5G responds in <1 ns, typical for silicon-based ESD protection diodes, significantly faster than most discrete TVS diodes (often >5 ns). This rapid turn-on ensures clamping occurs before transient energy reaches sensitive downstream circuitry - critical for protecting high-speed interfaces where even nanosecond delays cause failure. The ESD5102FCT5G datasheet confirms this via TLP I-V curve rise time in Figures 6 and 7.
