Product details
Overview
GS2970AIBTE3 from Semtech is a Transient Diverting Suppressor (TDS) designed for high-energy EOS protection of single 22V I/O or power lines. It delivers ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), 27.5–28V clamping voltage at 24–40A, and 20mΩ dynamic resistance - enabling robust USB Type-C PD bus protection in industrial and portable systems.
For engineers reviewing the GS2970AIBTE3 datasheet, pinout, applications, or equivalent options, this page provides verified electrical parameters, DFN-6 package layout guidance, temperature-stable clamping behavior, and direct alternatives for 22V bus protection in USB PD, load switch inputs, and IoT interfaces.
Technical Context
The GS2970AIBTE3 uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit upon detection of overvoltage. Unlike conventional TVS diodes, its clamping voltage remains nearly constant across 24–40A and −40°C to +125°C due to decreasing RDS(on) under surge conditions.
It operates with 22V reverse stand-off voltage, 25–27.9V breakdown voltage, and 175pF junction capacitance at 22V/1MHz. Its low 20mΩ dynamic resistance ensures minimal voltage rise during high-current transients, making it suitable for protecting sensitive 22V-rated controllers and load switches.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - matches nominal USB PD bus voltage and protects downstream 22V-rated ICs without leakage or false triggering. |
| Clamping Voltage | 27.5–28V at 24–40A (1.2/50μs + 8/20μs combo wave) - stays below typical 30V damage thresholds of USB PD controllers and load switches. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity requirements for industrial equipment and USB PD ports. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds USB IF and IEC standards for connector-level ESD robustness. |
| Dynamic Resistance | 20mΩ - enables stable clamping independent of current magnitude, unlike TVS diodes whose VC rises linearly with IPP. |
| Junction Capacitance | 175pF at 22V/1MHz - low enough for DC power rail protection; not intended for high-speed data lines. |
| Operating Temperature | −40°C to +125°C - supports operation in automotive cabin, industrial control, and ruggedized IoT environments. |
Pinout & Package
GS2970AIBTE3 is housed in a Pb-free, RoHS-compliant DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad (no internal thermal pad required). All six terminals are electrically active: three GND pins and three IN pins must be connected in parallel for full 40A surge rating and minimal parasitic inductance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return path for surge current; all three must be soldered to a low-inductance ground plane via multiple vias. |
| 4, 5, 6 | IN | Protected line input (e.g., VBUS in USB PD); all three pins connect in parallel to the same trace for distributed current handling and reduced impedance. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based transient shunting | Replaces traditional TVS diodes with a low-RDS(on) MOSFET switch, delivering flat clamping voltage across full current and temperature range. |
| Temperature-stable clamping | Clamping voltage varies <±0.5V from −40°C to +125°C at 40A - eliminates derating concerns in thermally demanding applications. |
| High-energy surge capability | 1120W peak pulse power (8/20μs) enables compliance with IEC 61000-4-5 ±1kV (RS=42Ω) on unsymmetrical lines. |
| Low dynamic resistance | 20mΩ measured between 1A–40A ensures minimal IR drop during surge, preserving voltage margin for protected ICs. |
| DFN-6 space efficiency | 1.6mm × 1.6mm footprint saves >50% board area vs. SOT-23 or SOIC TVS solutions while maintaining 40A rating. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |

Use Value: Delivers ±30kV ESD immunity and 40A surge handling in a 1.6mm² footprint - critical for compact, sealed IoT enclosures with no external shielding. |
Use Scenario: Protecting 20V DC input stages in ultrabooks and 2-in-1 tablets where USB-C PD charging introduces high-energy transients. IC Role / Device Role / Timing Role: Primary overvoltage clamp on the main system power rail upstream of buck converters and PMICs. Use Value: Ensures reliable operation under repeated 24A/40A surges without parameter drift - validated for continuous use across consumer lifecycle temperatures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P | Identical functional specification, pinout, and package; GS2970AIBTE3 is Semtech's alternate marking for TDS2211P per official ordering documentation. | No functional difference - used interchangeably in BOMs and layouts for USB PD and industrial power rail protection. | Select GS2970AIBTE3 when sourcing from authorized Semtech distribution channels with tape-and-reel packaging (3,000 pcs/reel). |
| uClamp2411ZA | 24V working voltage, lower 20A IPP rating, higher 33V clamping voltage, and smaller 0.65mm × 0.65mm DFN-2 package. | Better suited for CC/SBU lines in USB-C; insufficient for 40A VBUS protection due to lower surge rating and higher clamping. | Use uClamp2411ZA only for auxiliary signal lines - not a replacement for GS2970AIBTE3 in main power rail applications. |
Compared with TDS2211P, GS2970AIBTE3 is functionally identical and fully interchangeable; compared with uClamp2411ZA, it offers 2× peak current handling and 5.5V lower clamping - essential for protecting 22V power rails where voltage margin is constrained.

FAQ
What is the exact package type and dimensions of GS2970AIBTE3?
GS2970AIBTE3 uses a 6-pin DFN package measuring 1.6mm × 1.6mm × 0.55mm with exposed copper pad. Pin 1 is marked by a laser dot; pins 1–3 are GND, and pins 4–6 are IN. The land pattern follows Semtech's recommended layout with multiple ground vias and short, wide traces to minimize inductance - critical for achieving full 40A surge performance.
Does GS2970AIBTE3 meet IEC 61000-4-5 surge immunity standards?
Yes, GS2970AIBTE3 is rated for 40A peak pulse current (8/20μs waveform) and complies with IEC 61000-4-5 Level 4 testing at ±1kV (1.2/50μs voltage, 8/20μs current, RS = 42Ω) on unsymmetrical lines. Its 27.5–28V clamping voltage ensures protected circuits remain within safe operating limits during standardized surge events.
How does GS2970AIBTE3 differ from standard TVS diodes in clamping behavior?
Unlike TVS diodes - whose clamping voltage rises linearly with peak current (VC = VBR + IPP × RDYN) - GS2970AIBTE3 uses a triggered FET with decreasing RDS(on), resulting in near-constant 27.5–28V clamping from 24A to 40A and across −40°C to +125°C. This eliminates thermal derating and simplifies design margin analysis.
Can GS2970AIBTE3 be used on high-speed data lines like USB SuperSpeed?
No, GS2970AIBTE3 is not suitable for USB SuperSpeed (TX/RX), DisplayPort, or HDMI data lines. Its 175pF junction capacitance would severely degrade signal integrity. For those lines, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25pF); GS2970AIBTE3 is strictly intended for DC power rails and low-frequency control lines.
Is GS2970AIBTE3 pin-compatible with other Semtech TDS devices?
GS2970AIBTE3 shares the same DFN-6 pinout and terminal assignment (GND on pins 1–3, IN on pins 4–6) with TDS2211P and is functionally identical. However, it is not pin-compatible with other TDS variants like TDS1211P (12V) or TDS3311P (33V), which share the same package but differ in voltage rating and internal trigger thresholds.
