Product details
Overview
GS2964-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 stable 27.5–28V clamping across temperature and current range. Used in USB Type-C PD bus protection to prevent damage to controllers during lightning surges or connector hot-plug events.
For engineers reviewing the GS2964-INE3 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability under 40A surge, DFN-6 thermal and layout performance, 175pF junction capacitance at 22V, and compatibility with industrial-grade load switch input protection schemes.
Technical Context
The GS2964-INE3 uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses overvoltage beyond ~27V breakdown. Unlike conventional TVS diodes, its clamping voltage remains nearly constant-27.5–28V-across 24A to 40A surge currents due to decreasing RDS(on) under stress.
It operates from −40°C to +125°C with <600nA reverse leakage at 22V, 20mΩ dynamic resistance (measured 1–40A, 8/20μs), and maintains stable clamping across temperature-unlike standard TVS devices whose VC rises significantly with ambient heat.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - matches nominal USB PD bus voltage and avoids false triggering during normal operation. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo wave, RS=2Ω) - stays below typical 30V damage threshold of USB PD controllers. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds USB-IF and industrial ESD robustness requirements. |
| Junction Capacitance | 175pF at 22V, 1MHz - low enough for DC power rail protection without affecting transient response or system stability. |
| Dynamic Resistance | 20mΩ - enables near-constant clamping by minimizing V = I × R contribution across full surge range. |
| Package | DFN 1.6mm × 1.6mm × 0.55mm, 6-lead - enables ultra-compact placement adjacent to USB-C connectors or load switch inputs. |
Pinout & Package
GS2964-INE3 is housed in a RoHS-compliant, halogen-free DFN package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad (no solder mask defined). All six terminals are surface-mount; pins 1–3 are internally connected GND, pins 4–6 are internally connected IN - requiring external shorting on PCB for rated surge performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | Ground (GND) | Common return path for surge current; all three must be connected via low-inductance traces/vias to maximize 40A capability. |
| Pins 4, 5, 6 | Input (IN) | Protected line connection (e.g., VBus or load switch input); all three must be shorted externally to distribute surge current evenly. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based shunt architecture | Enables flat clamping curve (27.5–28V) across 24–40A, eliminating voltage rise seen in TVS diodes under surge stress. |
| Stable clamping over temperature | Clamping voltage variation <0.5V from −40°C to +125°C - ensures consistent protection in automotive or industrial enclosures. |
| Low dynamic resistance | 20mΩ measured 1–40A (8/20μs) - minimizes IR drop, enabling precise clamping independent of surge magnitude. |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 5kHz & 100kHz bursts) - protects against repetitive switching noise in motor drives or PLCs. |
| UL 94V-0 molding compound | Ensures flame-retardant reliability in enclosed industrial or medical equipment where safety certification is mandatory. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |

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-6 package, identical marking (T22XX), and same Semtech production lot traceability. | No functional difference; TDS2211P.C is the commercial-grade variant with identical performance and qualification level. | Select TDS2211P.C when sourcing through authorized distributors with standard lead times and volume pricing. |
| uClamp2411ZA | 24V working voltage, lower 24A IPP rating, higher 33V clamping, and smaller 0.65mm × 0.65mm 2-pin DFN package. | Targeted at CC/SBU lines in USB-C-not suitable for 22V VBus or load switch inputs due to lower surge rating and higher clamping. | Use uClamp2411ZA only for low-current signal-line protection; GS2964-INE3 remains required for high-energy power rail duty. |
Compared with TDS2211P.C (functionally identical) and uClamp2411ZA (lower energy rating, higher clamping), GS2964-INE3 provides the only validated 40A/22V solution with flat-clamp behavior essential for protecting sensitive PD controllers and industrial load switches.

FAQ
What is the primary protection function of the GS2964-INE3?
The GS2964-INE3 functions as a transient diverting suppressor that shunts high-energy EOS events-such as ESD, lightning surges, and EFT bursts-from protected 22V power or I/O lines to ground. Its FET-based architecture activates within nanoseconds to clamp voltage at 27.5–28V, preventing damage to downstream components like USB PD controllers or load switches. This behavior is confirmed in the Semtech TDS2211P datasheet, which applies directly to GS2964-INE3.
Does GS2964-INE3 require external bias or control signals to operate?
No, GS2964-INE3 is fully passive and self-triggering. It contains an integrated precision trigger circuit and surge-rated FET that activate automatically when input voltage exceeds ~27V breakdown. No external power, enable pin, or configuration is needed-making it a drop-in replacement for TVS diodes in existing layouts. All operational behavior is intrinsic to the GS2964-INE3 silicon design.
Can GS2964-INE3 be used on high-speed data lines like USB SuperSpeed or PCIe?
No, GS2964-INE3 is not suitable for high-speed data lines. Its 175pF junction capacitance at 22V would severely degrade signal integrity on differential pairs operating above 100MHz. It is explicitly designed for DC power rails or low-frequency I/O lines (e.g., USB-C VBus, CC, or load switch enable inputs). For SuperSpeed lanes, Semtech recommends RClamp3371ZC (<0.25pF), not GS2964-INE3.
How does GS2964-INE3 compare to standard TVS diodes in clamping performance?
Unlike standard TVS diodes-whose clamping voltage rises linearly with peak current (VC = VBR + IPP × RDYN)-the GS2964-INE3 maintains 27.5–28V clamping from 24A to 40A due to its FET's collapsing RDS(on). At 125°C, its clamping stays stable, whereas typical TVS devices exceed 38V under identical conditions. This flat-clamp behavior is a core specification of the GS2964-INE3.
What PCB layout practices are critical for optimal GS2964-INE3 performance?
To achieve rated 40A surge capability, all three GND pins (1–3) and all three IN pins (4–6) must be shorted externally using wide, low-inductance copper pours or traces. Place GS2964-INE3 within 5mm of the protected connector, use ≥3 vias per GND pin to internal ground planes, and avoid routing sensitive traces near its body. These guidelines are derived from Semtech's layout recommendations for the GS2964-INE3 footprint.
