Product details
Overview
GS2988-INE3 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 used in USB Type-C PD bus protection where low, temperature-invariant clamping prevents damage to 22V-tolerant controllers.
For engineers reviewing the GS2988-INE3 datasheet, pinout, applications, or equivalent options, key selection criteria include its constant-clamp FET architecture, DFN 1.6×1.6mm 6-lead package, 175pF junction capacitance at 22V, and suitability for industrial load switch input protection and USB PD interface surge hardening.
Technical Context
The GS2988-INE3 employs a surge-rated MOSFET as its primary shunt element, activated by a precision trigger circuit that senses overvoltage events above ~25V breakdown. Unlike conventional TVS diodes, its clamping voltage remains nearly flat-27.5–28V-from 24A to 40A (1.2/50μs + 8/20μs combo waveform, RS = 2Ω) due to decreasing RDS(on) under surge.
It operates from −40°C to +125°C with <600nA reverse leakage at 22V, 175pF capacitance at 1MHz/22V, and 20mΩ dynamic resistance (measured 1–40A, 8/20μs). Its functional architecture isolates protection from junction heating effects, enabling reliable performance in thermally constrained IoT and industrial edge nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC or RMS operating voltage on protected line without leakage or degradation |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo, RS = 2Ω) - ensures downstream 22V-rated ICs (e.g., USB PD controllers) remain below damage threshold during surge |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment and USB PD systems |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD requirements without external shielding |
| Junction Capacitance | 175pF at VR = 22V, f = 1MHz - low enough for USB Type-C VBUS line protection without signal integrity impact |
| Dynamic Resistance | 20mΩ (1–40A, 8/20μs) - enables near-constant clamping by minimizing IR drop increase under rising current |
| Package | DFN 1.6 × 1.6 × 0.55 mm, 6-lead - enables high-density placement adjacent to connectors with minimal PCB area (≈2.56 mm²) |
Pinout & Package
GS2988-INE3 is housed in a Pb-free, RoHS-compliant DFN 1.6 mm × 1.6 mm × 0.55 mm package with exposed thermal pad not required (energy dissipated in silicon). All six terminals are surface-mount; pin 1 is marked by laser dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path for surge current; all three must be connected to maximize current sharing and minimize inductance |
| Pins 4, 5, 6 | IN | Protected line input (e.g., VBUS); parallel connection provides lower effective impedance and higher total surge handling |
Key Features
| Feature | Design Value |
|---|---|
| FET-based transient diversion | Replaces conventional TVS with active shunt switching, delivering flat clamping independent of temperature and current magnitude |
| Stable clamping across temperature | 27.5–28V clamping maintained from −40°C to +125°C - eliminates derating uncertainty in industrial or automotive under-hood environments |
| High-energy surge rating | 1120W peak pulse power (8/20μs) supports robust protection against lightning-induced surges in remote meters and robotics |
| Low leakage & capacitance | <600nA IR at 22V and 175pF at 1MHz enable use on always-on power rails without standby current penalty or bandwidth limitation |
| Space-optimized DFN | 1.6×1.6mm footprint saves >50% board area vs. SO-8 or SOT-23 TVS solutions while supporting same 40A surge rating |
Applications

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 (T22XX), but ordered via Semtech's standard tape-and-reel channel (3,000 pcs/reel). | Same USB PD, load switch, and industrial rail protection use cases; validated in Semtech reference designs including Figure 4 and Figure 5. | Select TDS2211P.C when sourcing through authorized distributors (Digi-Key, Mouser) or requiring standard reel packaging. |
| uClamp2411ZA.TCT | 24V working voltage, ±30kV ESD, but uses silicon avalanche diode architecture; clamping rises to ~36V at 24A and increases with temperature. | Suitable for CC/SBU lines in USB Type-C where lower capacitance (<0.3pF) is critical-but not recommended for 22V VBUS due to higher, temperature-sensitive clamping. | Choose uClamp2411ZA.TCT only for low-capacitance signal-line protection; avoid for power-rail applications requiring flat clamping like GS2988-INE3 delivers. |
Compared with TDS2211P.C (identical function and form) and uClamp2411ZA.TCT (different architecture, higher clamping), GS2988-INE3 offers guaranteed 27.5–28V clamping stability across current and temperature-making it the preferred choice for 22V power rail protection where margin-critical ICs demand predictable voltage limiting.

FAQ
What is the exact clamping voltage specification for GS2988-INE3 at 40A surge current?
The GS2988-INE3 clamps at 27.6–28V under 40A peak pulse current (1.2/50μs voltage + 8/20μs current combination waveform, RS = 2Ω), per its official datasheet Table "Electrical Characteristics." This value is guaranteed across −40°C to +125°C and reflects the device's FET-based architecture delivering near-constant voltage limiting-unlike conventional TVS diodes whose clamping rises linearly with current.
Is GS2988-INE3 pin-compatible with other Semtech TDS devices like TDS2211P.C?
Yes, GS2988-INE3 is pin-compatible with TDS2211P.C: both use identical DFN 1.6×1.6mm 6-lead packages with pins 1–3 as GND and pins 4–6 as IN. The marking code (T22XX) and electrical specifications-including 22V working voltage, 40A surge rating, and 27.5–28V clamping-are fully aligned. GS2988-INE3 is a valid alternate ordering variant for the same functional device.
Can GS2988-INE3 be used to protect USB Type-C VBUS lines operating up to 20V under USB PD 3.1?
Yes, GS2988-INE3 is explicitly validated for USB Type-C VBUS protection in Semtech's application documentation (Figure 4). Its 22V working voltage and stable 27.5–28V clamping ensure safe operation across the full USB PD 3.1 voltage range (up to 20V nominal, 22V max), preventing damage to PD controllers and load switches during ±30kV ESD or 40A surge events.
Does GS2988-INE3 require a thermal pad or heatsink on the PCB?
No, GS2988-INE3 does not require a thermal pad or external heatsink. Its DFN package dissipates surge energy within the silicon die, and Semtech's datasheet confirms "no thermal pad is needed" (page 6). Layout best practice is to connect all GND pins (1–3) and IN pins (4–6) with short, wide traces and multiple vias to internal ground planes to minimize parasitic inductance-not to add thermal mass.
How does GS2988-INE3 differ from standard TVS diodes in terms of temperature performance?
GS2988-INE3 maintains 27.5–28V clamping from −40°C to +125°C, whereas standard TVS diodes exhibit rising clamping voltage with temperature due to positive temperature coefficient of VBR and fixed dynamic resistance. This makes GS2988-INE3 uniquely suited for industrial and automotive applications where ambient temperature swings would otherwise degrade TVS protection margins unpredictably.
