Product details
Overview
GS2984-INTE3D 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 stable 27.5–28V clamping across full current and temperature ranges (−40°C to +125°C). It protects USB Type-C power delivery buses, load switch inputs, and industrial I/O interfaces using solid-state FET-based shunting.
For engineers reviewing the GS2984-INTE3D datasheet, pinout, applications, or equivalent options, key selection criteria include its constant-clamp behavior under surge, low 20mΩ dynamic resistance, 175pF junction capacitance at 22V, DFN 1.6×1.6mm package with 6-pin symmetric I/O/GND layout, and suitability for high-reliability USB PD and industrial equipment protection.
Technical Context
The GS2984-INTE3D uses a precision-triggered surge-rated FET as its primary protection element-unlike conventional TVS diodes-enabling near-constant clamping voltage independent of peak pulse current magnitude. Its trigger circuit activates the shunt FET when transient voltage exceeds breakdown, leveraging ultra-low RDS(on) to maintain clamping at ~27.5–28V from 24A to 40A (1.2/50μs + 8/20μs combination waveform, RS = 2Ω).
Clamping stability extends across −40°C to +125°C operating temperature, with breakdown voltage (VBR) ranging 25–27.9V and reverse stand-off voltage (VRWM) fixed at 22V. Dynamic resistance is guaranteed at ≤20mΩ (measured 1A–40A, 8/20μs), and junction capacitance remains 175pF at 22V/1MHz-critical for minimizing signal distortion on protected lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC bus voltage it safely guards without leakage or degradation. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs/1.2/50μs combo wave, RS=2Ω) - ensures downstream ICs (e.g., USB PD controllers) remain below damage thresholds during surges. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements for 22V systems. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD robustness standards for connector-facing protection. |
| Dynamic Resistance | ≤20mΩ - enables minimal voltage rise under surge, directly enabling flat clamping performance across current range. |
| Junction Capacitance | 175pF at 22V/1MHz - low enough for USB PD VBUS line protection without compromising signal integrity or EMC. |
| Operating Temperature | −40°C to +125°C - supports deployment in extended-temperature industrial, automotive, and outdoor IoT environments. |
Pinout & Package
GS2984-INTE3D is housed in a RoHS-compliant, halogen-free DFN package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad (not electrically connected). The package features six terminals arranged in a 3×2 configuration: pins 1–3 are GND, pins 4–6 are IN - all must be soldered for rated 40A surge capability and optimal thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | Ground (GND) | Common return path for surge current; all three must be connected to PCB ground plane via low-inductance routing or multiple vias. |
| Pins 4, 5, 6 | Input (IN) | Protected line connection (e.g., USB PD VBUS, load switch input); parallel connection ensures current sharing and minimizes trace inductance. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based transient shunting | Replaces traditional TVS diodes with active switching-enables flat clamping vs. current/temperature where conventional TVS exhibits linear VC = VBR + IPP×RDYN rise. |
| Constant clamping voltage | 27.5–28V maintained from 24A to 40A and −40°C to +125°C-eliminates derating uncertainty in thermal design and surge margin analysis. |
| High-energy surge rating | 1120W peak pulse power (8/20μs)-supports compliance with IEC 61000-4-5 ±1kV (RS=42Ω) on unsymmetrical lines. |
| Low dynamic resistance | ≤20mΩ-minimizes IR drop during surge, preserving clamping accuracy and reducing self-heating under repeated transients. |
| Compact DFN footprint | 1.6×1.6mm area-reduces board space by >50% versus SOT-23 or SOIC alternatives while maintaining 40A capability. |

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 (pins 1–3 GND, 4–6 IN), and identical marking (T22 + date code). | No functional difference; TDS2211P.C is the standard commercial-grade variant-GS2984-INTE3D is Semtech's alternate orderable part number for the same device. | Select GS2984-INTE3D when sourcing through Aetrix Electronics' channel; both share full datasheet compliance and qualification. |
| uClamp2411ZA | 24V working voltage, lower 24A peak pulse rating, higher 30V clamping, and smaller 0.6×0.3mm DFN package-designed for CC/SBU lines, not main power rails. | Targeted for low-capacitance (<0.5pF), low-current signal-line protection-not suitable for 40A VBUS or load switch inputs. | Use uClamp2411ZA only for auxiliary USB Type-C control lines; GS2984-INTE3D remains required for primary 22V power rail protection. |
Compared with TDS2211P.C (identical function and form) and uClamp2411ZA (lower-power signal-line variant), GS2984-INTE3D provides the only validated 40A/22V constant-clamp solution in this footprint-making it irreplaceable for high-energy industrial and USB PD power rail protection.

FAQ
What is the primary protection function of the GS2984-INTE3D?
The GS2984-INTE3D functions as a Transient Diverting Suppressor that actively shunts high-energy electrical overstress (EOS) events-including ESD, lightning surges, and fast transients-to ground using an integrated surge-rated FET. Unlike passive TVS diodes, it maintains a stable 27.5–28V clamping voltage across its full 40A surge rating and −40°C to +125°C operating range, making GS2984-INTE3D ideal for protecting sensitive 22V power rails in USB PD and industrial systems.
Does the GS2984-INTE3D require external bias or control signals to operate?
No, the GS2984-INTE3D operates autonomously without any external bias, enable signals, or configuration. Its internal precision trigger circuit detects overvoltage conditions on the IN pins (4–6) and instantly activates the shunt FET-converting the device into a low-resistance path to GND (pins 1–3). This fully passive, zero-latency response ensures GS2984-INTE3D delivers protection immediately upon transient onset, with no firmware, timing constraints, or supporting components needed.
How does the GS2984-INTE3D differ from standard TVS diodes in clamping behavior?
Standard TVS diodes exhibit linear clamping voltage rise (VC = VBR + IPP × RDYN) due to fixed dynamic resistance, causing clamping to increase with surge current and temperature. In contrast, GS2984-INTE3D uses a triggered FET with decreasing RDS(on) under surge-resulting in near-constant 27.5–28V clamping from 24A to 40A and across −40°C to +125°C. This eliminates thermal derating uncertainty and ensures predictable protection margins for GS2984-INTE3D in real-world operating conditions.
Can the GS2984-INTE3D be used on high-speed data lines like USB SuperSpeed or PCIe?
No, the GS2984-INTE3D is not intended for high-speed data line protection. With 175pF junction capacitance at 22V, it would severely degrade signal integrity on differential pairs operating above ~100MHz. It is engineered exclusively for 22V power rails and low-bandwidth I/O lines (e.g., USB PD VBUS, load switch enable inputs). For SuperSpeed lanes, Semtech recommends dedicated low-capacitance devices like RClamp3371ZC (<0.25pF), not GS2984-INTE3D.
What PCB layout practices maximize surge performance for the GS2984-INTE3D?
To maximize surge performance, place GS2984-INTE3D as close as possible to the protected connector or entry point. Connect all three IN pins (4–6) together with a short, wide trace to the protected line, and tie all three GND pins (1–3) directly to a solid ground plane using ≥3 thermal vias. Avoid stubs or narrow traces-these add parasitic inductance that increases clamping voltage during fast transients. Do not use thermal relief on GND pads; full copper connection is required for GS2984-INTE3D to handle 40A peak current reliably.
