Product details
Overview
GS3441-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), 27.5–28V clamping at 40A, 20mΩ dynamic resistance, and 175pF junction capacitance in a DFN 1.6×1.6×0.55mm 6-lead package. It protects USB Type-C PD buses, load switch inputs, and industrial interfaces where stable clamping under temperature and current stress is critical.
For engineers reviewing the GS3441-INE3 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability across 40A and −40°C to +125°C, low dynamic resistance, DFN board-space efficiency, and compatibility with 22V operating voltage systems such as USB PD and industrial power rails.
Technical Context
The GS3441-INE3 uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events. Unlike conventional TVS diodes, its clamping voltage remains nearly constant-27.5–28V-across the full 40A peak pulse current range due to the FET's decreasing RDS(on) under surge conditions.
It operates with a 22V reverse stand-off voltage (VRWM) and 25–27.9V breakdown voltage (VBR), exhibits only 130–600nA leakage at VRWM, and maintains stable 175pF capacitance at 22V and 1MHz. Its thermal performance supports continuous operation from −40°C to +125°C ambient.
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 conduction. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - ensures downstream 24V-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 input stages. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - provides robust handling of human-body-model ESD events at connector interfaces. |
| Dynamic Resistance | 20mΩ - enables minimal voltage rise under high di/dt transients, critical for fast-rising lightning-induced surges. |
| Junction Capacitance | 175pF at 22V, 1MHz - low enough for 22V power rail protection without signal integrity impact on adjacent traces. |
| Operating Temp. | −40°C to +125°C - supports deployment in automotive under-hood, industrial PLC, and outdoor IoT environments. |
Pinout & Package
GS3441-INE3 is housed in a Pb-free, RoHS-compliant DFN package measuring 1.6mm × 1.6mm × 0.55mm with six terminals. The package features exposed thermal pad-less construction and UL 94V-0 molding compound.

|---|---|
Use Scenario: Protecting 20–22V VBUS lines in USB Type-C receptacles against ESD, lightning-induced surges, and hot-plug transients. IC Role / Device Role / Timing Role: Transient diverting suppressor placed directly at the connector, shunting surge energy to ground before it reaches the PD controller or buck converter. Use Value: Maintains 27.5–28V clamping across temperature and current - prevents overvoltage damage to 24V-rated PD controllers without requiring oversized TVS devices. |
Use Scenario: Safeguarding the input of high-side load switches (e.g., HS2950P) in remote meters, robotics, and factory automation systems. IC Role / Device Role / Timing Role: Primary front-end surge clamp that limits voltage seen by the load switch's internal MOSFET gate oxide and drain-source junction. Use Value: 20mΩ dynamic resistance and flat clamping prevent latch-up or avalanche failure in the load switch during 40A transients. |
| IoT Edge Node Power Rail Protection | Storage Device 22V Backup Supply Protection |
Use Scenario: Securing 22V auxiliary power rails in battery-backed wireless sensors and gateway modules exposed to field ESD and induced surges. IC Role / Device Role / Timing Role: Standalone EOS protector on main DC input, operating in parallel with low-leakage LDOs or buck regulators. Use Value: 130–600nA reverse leakage at 22V minimizes standby power loss - essential for multi-year battery life in edge deployments. |
Use Scenario: Protecting 22V backup supplies in NVMe SSDs and enterprise storage controllers against power-rail transients during hot-swap or system reset. IC Role / Device Role / Timing Role: Fast-acting shunt device placed upstream of power management ICs and flash memory VCC regulators. Use Value: 175pF capacitance avoids resonance or ringing on 22V supply lines - preserves power integrity during high-speed storage operations. |
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 (T22 code), but differs in reel quantity (3,000 pcs vs. GS3441-INE3's unspecified quantity). | Same use cases: USB PD, load switch, industrial 22V rails. No functional deviation in circuit design. | Select TDS2211P.C when standard Semtech tape-and-reel logistics are preferred; GS3441-INE3 may reflect alternate packaging or distribution channel. |
| uClamp2411ZA | 24V working voltage, lower 24A IPP rating, higher 30V clamping at 24A, smaller 0.6×0.3mm 2-pin SOD-323 package, and 12pF capacitance. | Better suited for CC/SBU lines in USB Type-C; insufficient for 40A VBUS protection due to lower surge rating and higher clamping. | Use uClamp2411ZA only for low-capacitance, low-current signal-line protection - not a functional replacement for GS3441-INE3 on power rails. |
Compared with TDS2211P.C, GS3441-INE3 offers identical protection performance and layout compatibility; compared with uClamp2411ZA, GS3441-INE3 provides 67% higher surge current capacity and 2.5V lower clamping at rated current - making it the sole suitable choice for 22V power rail EOS hardening.

FAQ
What is the exact pin configuration and connection requirement for GS3441-INE3?
GS3441-INE3 uses a 6-pin DFN package with pins 1–3 designated as GND and pins 4–6 as IN. All three GND pins must be connected to a low-inductance ground plane, and all three IN pins must be shorted together externally to ensure uniform current sharing and full 40A surge capability. Failure to connect all six pins degrades clamping performance and peak current rating. The GS3441-INE3 datasheet confirms this configuration is mandatory for compliance with IEC 61000-4-5.
Does GS3441-INE3 meet IEC 61000-4-5 Level 4 surge immunity?
Yes, GS3441-INE3 is rated for 40A peak pulse current with an 8/20μs waveform, which satisfies IEC 61000-4-5 Level 4 (2kV open-circuit, 1kV into 42Ω source impedance) for 22V systems. Its 27.5–28V clamping voltage at 40A ensures protected circuits remain within safe operating limits during standardized surge testing. This performance is verified in the GS3441-INE3 datasheet under Electrical Characteristics and Typical Characteristics sections.
How does GS3441-INE3 differ from standard TVS diodes in clamping behavior?
Unlike standard TVS diodes whose clamping voltage rises linearly with peak current (VC = VBR + IPP × RDYN), GS3441-INE3 uses a triggered FET architecture that maintains near-constant clamping-27.5–28V-from 1A to 40A. This results from decreasing RDS(on) under surge, yielding 20mΩ dynamic resistance. The GS3441-INE3 datasheet explicitly contrasts this behavior with conventional TVS in the Application Information section.
Can GS3441-INE3 be used for USB Type-C VBUS protection alongside RClamp3371ZC?
Yes - GS3441-INE3 is specified for VBUS (power) line protection in USB Type-C designs, while RClamp3371ZC handles low-capacitance (<0.25pF) protection for SuperSpeed data lanes. The GS3441-INE3 datasheet cites this exact co-deployment in Figure 4, confirming interoperability and complementary roles: GS3441-INE3 manages high-energy surges on the 20–22V bus, and RClamp3371ZC preserves signal integrity on differential pairs.
What is the maximum operating temperature and thermal derating profile for GS3441-INE3?
GS3441-INE3 operates from −40°C to +125°C ambient with no derating required for clamping voltage or peak pulse current. Its clamping voltage stays within 27.5–28V across the full temperature range, and peak pulse current remains rated at 40A (8/20μs) up to +125°C. This stability is confirmed in the GS3441-INE3 datasheet's Typical Characteristics plots for clamping voltage vs. temperature and peak pulse current vs. temperature.
