Product details
Overview
GS2986-INTE3 from Semtech is a Transient Diverting Suppressor (TDS) designed for high-energy EOS protection of 22V-rated power or I/O lines. It delivers ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), and a stable 27.5–28V clamping voltage across temperature and current range. It is deployed in USB Type-C PD bus protection to prevent damage to controllers during lightning surges or connector hot-plug events.
For engineers reviewing the GS2986-INTE3 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability under 40A transients, low dynamic resistance (<20 mΩ), junction capacitance (175 pF at 22V), DFN 1.6×1.6mm package constraints, and compatibility with industrial-grade thermal operation (−40°C to +125°C).
Technical Context
The GS2986-INTE3 uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit when transient voltage exceeds breakdown. Unlike conventional TVS diodes, its clamping voltage remains nearly constant-27.5–28V-across 24A to 40A peak pulse currents due to decreasing RDS(on) under surge conditions.
It operates with a 22V reverse stand-off voltage and 25–27.9V breakdown voltage, enabling robust protection for 20V nominal USB PD buses. Its solid-state architecture avoids junction heating limitations, maintaining performance up to +125°C without derating IPP or VC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-Off Voltage | 22 V - Maximum continuous operating voltage before triggering; matches USB PD 20V bus with 2V margin. |
| Clamping Voltage (IPP = 40A) | 27.5–28 V - Limits protected IC stress during worst-case 8/20μs surges; stays flat across temperature. |
| Peak Pulse Current | 40 A (8/20μs) - Withstands industrial-level lightning surges per IEC 61000-4-5 with 2Ω source impedance. |
| Dynamic Resistance | 20 mΩ - Enables low-voltage drop during conduction; critical for minimizing voltage overshoot on fast-rising transients. |
| Junction Capacitance | 175 pF @ 22V, 1MHz - Low enough for 22V power rail protection without signal integrity impact on DC/low-frequency paths. |
| ESD Withstand | ±30 kV contact & air (IEC 61000-4-2) - Survives repeated human-body-model ESD events at connector interfaces. |
| Operating Temperature | −40°C to +125°C - Fully specified performance across automotive and industrial ambient ranges without derating. |
Pinout & Package
GS2986-INTE3 is housed in a Pb-free, RoHS-compliant DFN package measuring 1.6 mm × 1.6 mm × 0.55 mm with six terminals. The package features three parallel ground pins (1, 2, 3) and three parallel input pins (4, 5, 6) to minimize parasitic inductance and maximize surge current handling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return path; all three must be connected to PCB ground plane via multiple vias for full 40A capability. |
| 4, 5, 6 | IN | Protected line input; tied together to interface with 22V bus or power rail; requires direct routing from connector. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5 V from 24A to 40A (8/20μs), eliminating design uncertainty from current-dependent VC rise. |
| Low dynamic resistance | 20 mΩ ensures minimal IR drop during surge conduction, preserving voltage margin for downstream 22V-tolerant ICs. |
| Temperature-stable clamping | VC remains 27.5–28 V from −40°C to +125°C-no derating needed for high-temp industrial deployments. |
| High-energy EOS protection | Rated for 1120 W peak pulse power (8/20μs), exceeding common 1kV/42Ω surge test requirements. |
| DFN space efficiency | 1.6×1.6 mm footprint saves >50% board area vs. SO-8 or SOT-23 TVS alternatives while supporting same surge rating. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting the VBus line of a USB Type-C port supporting up to 20V/5A PD negotiation against ESD, lightning-induced surges, and hot-plug transients. IC Role / Device Role / Timing Role: Primary EOS shunt protector placed directly at the connector, clamping transients before they reach the PD controller or load switch. Use Value: Maintains 27.5–28V clamping across 40A surges and full temperature range-prevents false overvoltage shutdowns and ensures reliable PD communication under stress. |
Use Scenario: Safeguarding the input of industrial-grade load switches (e.g., HS2950P) used in remote meters, robotics, or IoT edge nodes exposed to 1kV/42Ω surges. IC Role / Device Role / Timing Role: Front-end transient suppressor that limits voltage seen by the load switch's internal FET gate oxide and drain-source junction. Use Value: Prevents permanent damage to the load switch during field surges by holding clamping voltage below 30V-well under typical 30–40V FET breakdown thresholds. |
| IoT Device Power Rail Protection | Storage Device 22V Supply Line Protection |
Use Scenario: Securing the main 22V input rail of battery-powered or PoE-powered IoT gateways subjected to EFT bursts (±4kV, 5/50ns) and ESD events in uncontrolled environments. IC Role / Device Role / Timing Role: Solid-state transient diverter that activates within nanoseconds to shunt energy to ground without degrading over time. Use Value: Delivers 4kV EFT immunity and ±30kV ESD robustness while maintaining low leakage (<600 nA), extending battery life in always-on sensing applications. |
Use Scenario: Protecting the 22V auxiliary supply rail in NVMe SSD enclosures or enterprise storage backplanes against coupling from adjacent high-speed data lanes or power sequencing faults. IC Role / Device Role / Timing Role: High-reliability clamp positioned between power connector and DC-DC input stage to absorb coupled transients. Use Value: 175 pF capacitance avoids resonance with typical 10–100 μF bulk capacitors; stable VC prevents brownout or reset during transient events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P.C | Identical electrical specs, same DFN 1.6×1.6mm package, identical pinout and marking (T22 code); differs only in reel packaging (3,000 pcs/reel vs. GS2986-INTE3's unspecified quantity). | Direct fit for USB PD and industrial load switch designs requiring Semtech's TDS architecture and 22V standoff. | Select TDS2211P.C when standard tape-and-reel logistics and traceable date coding (XX) are required. |
| uClamp2411ZA | 24V standoff, lower 24A IPP rating, higher 33V clamping voltage, smaller 0.6×0.3mm DFN package, and 12 pF capacitance-optimized for CC/SBU lines, not power rails. | Suitable only for low-capacitance, low-energy signal-line protection-not rated for 40A surges or 22V bus clamping. | Use uClamp2411ZA for USB Type-C CC/SBU lines; avoid for VBus or power rail protection where GS2986-INTE3's 40A/28V capability is essential. |
Compared with TDS2211P.C, GS2986-INTE3 offers identical protection performance but may differ in packaging or traceability; compared with uClamp2411ZA, GS2986-INTE3 provides 67% higher surge current rating and 5V lower clamping-making it the sole suitable choice for 22V power rail EOS hardening.

FAQ
What is the maximum clamping voltage of GS2986-INTE3 at 40A peak pulse current?
The GS2986-INTE3 clamps at 27.5–28 V when subjected to a 40A peak pulse current with an 8/20μs waveform and 2Ω source impedance. This value is guaranteed across −40°C to +125°C and reflects its constant-clamp FET-based architecture-not a rising curve like traditional TVS devices. The GS2986-INTE3 maintains this tight window without derating.
Does GS2986-INTE3 meet IEC 61000-4-5 surge immunity standards?
Yes, GS2986-INTE3 is rated for 40A (8/20μs) and ±1kV (1.2/50μs, RS = 42Ω) per IEC 61000-4-5, making it suitable for industrial equipment and USB PD systems requiring compliance with common surge immunity standards. Its 27.5–28V clamping ensures protected ICs remain within safe operating voltage margins during these tests. GS2986-INTE3 achieves this without external components or layout dependencies beyond proper grounding.
How does GS2986-INTE3 differ from standard TVS diodes in clamping behavior?
Unlike standard TVS diodes-whose clamping voltage rises linearly with peak pulse current (VC = VBR + IPP × RDYN)-the GS2986-INTE3 uses a triggered FET to achieve near-constant clamping (27.5–28V) from 24A to 40A. Its dynamic resistance drops under surge, preventing voltage overshoot. This eliminates design uncertainty caused by temperature- and current-dependent VC drift in conventional TVS devices. GS2986-INTE3 delivers predictable protection across real-world surge profiles.
What is the recommended PCB layout for GS2986-INTE3 to achieve full 40A surge capability?
To achieve full 40A surge rating, all three GND pins (1, 2, 3) must connect to a solid ground plane using ≥3 vias each, and all three IN pins (4, 5, 6) must tie directly to the protected line with minimal trace length-ideally placed within 3 mm of the connector. Avoid stubs or splits; use wide, short copper pours. Thermal relief is unnecessary-the GS2986-INTE3 dissipates energy in the FET channel, not the junction. Layout adherence ensures specified clamping and current-handling performance.
Is GS2986-INTE3 compatible with automated optical inspection (AOI) and reflow processes?
Yes, GS2986-INTE3 uses a standard DFN 1.6×1.6mm package with lead-free, halogen-free, RoHS/WEEE-compliant construction and UL 94V-0 molding compound. Its top-side laser marking (T22 + date code) supports AOI verification, and its thermal profile aligns with IPC/JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1). Reflow follows standard Pb-free profiles with peak temperatures up to 260°C. GS2986-INTE3 has been validated in high-volume manufacturing environments for USB PD and industrial applications.
