Product details
Overview
GS2964-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 full temperature range (−40°C to +125°C). It is used in USB Type-C PD bus protection where low, temperature-invariant clamping prevents damage to PD controllers.
For engineers reviewing the GS2964-INTE3 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability over temperature, dynamic resistance ≤20 mΩ, junction capacitance of 175 pF at 22V, and DFN 1.6×1.6mm 6-lead package compatibility with high-density USB and industrial PCB layouts.
Technical Context
The GS2964-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 across 1–40A peak pulse current due to decreasing RDS(on) under surge conditions.
It operates with reverse stand-off voltage of 22V, breakdown voltage of 25–27.9V, and exhibits <600 nA leakage at VRWM. Its functional architecture enables stable 27.5–28V clamping under both 1.2/50μs + 8/20μs combination waveforms (RS = 2Ω) and maintains performance from −40°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22 V - defines maximum continuous DC operating voltage on protected line without leakage or conduction. |
| Clamping Voltage | 27.5–28 V at 40A (8/20μs) - ensures downstream ICs (e.g., USB PD controllers) remain below absolute maximum ratings during surge events. |
| Peak Pulse Current | 40 A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements for 22V systems. |
| ESD Withstand | ±30 kV contact & air (IEC 61000-4-2) - provides robust handling-level ESD protection without degradation. |
| Junction Capacitance | 175 pF at 22V, 1 MHz - low enough for 22V power rail protection without signal integrity impact on adjacent traces. |
| Dynamic Resistance | 20 mΩ - enables near-constant clamping by minimizing IR drop increase across rated current range. |
Pinout & Package
GS2964-INTE3 is housed in a RoHS-compliant DFN 1.6 mm × 1.6 mm × 0.55 mm 6-lead package with exposed thermal pad not required (energy dissipated in silicon). All pins must be soldered: Pins 1–3 are ground terminals; Pins 4–6 are input terminals connected in parallel to the protected line.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path for surge current; all three must be connected to minimize inductance and maximize 40A capability. |
| Pins 4, 5, 6 | IN | Parallel-connected input terminals tied to protected 22V bus; shared connection ensures uniform current sharing and optimal clamping. |
Key Features
| Feature | Design Value |
|---|---|
| Temperature-stable clamping | 27.5–28 V clamping maintained from −40°C to +125°C - eliminates derating concerns in industrial or automotive ambient environments. |
| FET-based shunt architecture | Replaces pn-junction TVS with low-RDS(on) MOSFET - achieves flat clamping curve vs. current, unlike linear VC = VBR + IPP×RDYN behavior. |
| High-energy surge rating | 1120 W peak pulse power (8/20μs) - supports repeated lightning-surge events per IEC 61000-4-5 without parametric shift. |
| Low leakage & high impedance standby | <600 nA reverse leakage at 22V - avoids loading on 22V power rails or battery-backed circuits during normal operation. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting VBUS lines in USB Type-C ports supporting up to 20V PD negotiation, exposed to ESD and system-level surges. IC Role / Device Role / Timing Role: Primary EOS suppressor placed directly at connector, clamping transients before they reach PD controller or load switch. Use Value: Maintains 27.5–28 V clamping across temperature and current - keeps PD controller within safe operating area without over-specifying IPP. |
Use Scenario: Safeguarding input of industrial-grade load switches (e.g., HS2950P) in remote meters, robotics, or factory automation equipment. IC Role / Device Role / Timing Role: Front-end transient shunt that diverts surge energy away from the load switch's internal FET gate oxide. Use Value: Prevents gate-oxide failure by limiting voltage across switch input to ≤28 V during ±1 kV (1.2/50 μs) surges. |
| IoT Edge Node Power Rail Protection | Storage Device 22V Backup Supply Protection |
Use Scenario: Securing 22V auxiliary power inputs in battery-backed IoT gateways or edge AI nodes deployed in electrically noisy environments. IC Role / Device Role / Timing Role: Standalone EOS protector on main DC input rail, co-located with input capacitor and connector. Use Value: 175 pF capacitance avoids resonance with typical 10–100 μF bulk capacitors; 40A rating handles induced lightning currents in outdoor deployments. |
Use Scenario: Protecting 22V backup supply lines in NVMe SSDs or enterprise storage enclosures subject to hot-plug and ESD events. IC Role / Device Role / Timing Role: Low-leakage (≤600 nA) clamp ensuring minimal quiescent drain on backup batteries during long idle periods. Use Value: Enables reliable 10-year shelf life for backup power while delivering ±30 kV ESD immunity at connector interface. |
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 marking (T22), and same tape-and-reel packaging (3,000/reel). | No functional difference; TDS2211P.C is the standard orderable variant - GS2964-INTE3 is a Semtech-authorized distribution variant with identical performance. | Select GS2964-INTE3 for Aetrix Electronics supply chain continuity; select TDS2211P.C for direct Semtech channel sourcing. |
| uClamp2411ZA | 24 V working voltage, lower 20A IPP rating, higher 33 V clamping, and smaller 0.65×0.65mm DFN package. | Targeted at CC/SBU lines in USB Type-C, not VBUS; unsuitable for 22V power rail protection due to higher clamping and lower surge rating. | Use only for low-voltage, low-capacitance signal-line protection; not a functional substitute for GS2964-INTE3 in power-rail roles. |
Compared with TDS2211P.C, GS2964-INTE3 offers identical protection performance and footprint but leverages Aetrix's volume procurement and lifecycle management; versus uClamp2411ZA, it delivers 2× peak current handling and 5 V lower clamping - critical for 22V PD bus integrity.

FAQ
What is the exact clamping voltage specification for GS2964-INTE3 at 40A surge current?
The GS2964-INTE3 clamps at 27.6–28 V under 40A peak pulse current (tp = 8/20μs) with 1.2/50μs voltage waveform and 2Ω source impedance, per IEC 61000-4-5. This value is guaranteed across −40°C to +125°C and reflects the device's FET-based architecture, not a fixed VBR + IPP×RDYN relationship.
Is GS2964-INTE3 pin-compatible with TDS2211P.C?
Yes - GS2964-INTE3 and TDS2211P.C share identical DFN 1.6×1.6mm 6-lead package, pin numbering (Pins 1–3 = GND, Pins 4–6 = IN), land pattern, and thermal profile. Both are marked "T22" and shipped in 3,000-unit 7″ reels, enabling direct substitution without PCB changes.
Does GS2964-INTE3 require a thermal pad or heatsink on the PCB?
No - GS2964-INTE3 dissipates surge energy in the silicon die, not through a thermal pad. The DFN package has no exposed thermal slug; layout guidelines emphasize low-inductance grounding via multiple vias under Pins 1–3, not thermal copper pour.
Can GS2964-INTE3 protect USB SuperSpeed differential pairs (TX/RX)?
No - GS2964-INTE3 is rated for 175 pF junction capacitance at 22V, making it suitable only for power or single-ended I/O lines. For USB SuperSpeed lanes, Semtech recommends RClamp3371ZC (<0.25 pF), which is specifically designed for high-speed data line protection without signal distortion.
What is the maximum operating temperature range for GS2964-INTE3?
The GS2964-INTE3 is specified for continuous operation from −40°C to +125°C ambient temperature. Its clamping voltage, leakage current, and dynamic resistance remain within datasheet limits across this full range, validated per JEDEC JESD22-A108.
