Product details

Overview

GS3241-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 its full current and temperature range (−40°C to +125°C). It is deployed in USB Type-C PD bus protection where precise clamping below controller damage thresholds is critical.

For engineers reviewing the GS3241-INE3 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability under surge current and temperature, low dynamic resistance (20 mΩ), junction capacitance (175 pF at 22V), and DFN 1.6×1.6mm 6-lead layout compatibility with high-density USB and industrial interfaces.

Technical Context

The GS3241-INE3 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-27.5–28V-across 24A to 40A (1.2/50μs + 8/20μs combination waveform) due to decreasing R_DS(on) under surge.

It operates over −40°C to +125°C with reverse stand-off voltage (V_RWM) of 22V, breakdown voltage (V_BR) of 25–27.9V, and reverse leakage <600 nA at 22V. Its 175 pF junction capacitance and 20 mΩ dynamic resistance support robust signal integrity in 22V power rail and load-switch input protection roles.

Key Specifications

Parameter	Value and Actual Design Meaning
Working Voltage	22 V - Matches nominal USB PD bus and industrial 22V supply rails without derating.
Clamping Voltage	27.5–28 V at 40A (8/20μs) - Remains stable across temperature and current, enabling predictable downstream IC protection.
Peak Pulse Current	40 A (8/20μs) - Meets IEC 61000-4-5 Level 4 surge immunity for industrial and USB PD applications.
ESD Withstand	±30 kV contact & air (IEC 61000-4-2) - Exceeds automotive and industrial ESD requirements without external staging.
Junction Capacitance	175 pF at 22 V, 1 MHz - Low enough for 22V power-line protection without degrading transient response or causing signal distortion.
Dynamic Resistance	20 mΩ (8/20μs, 1–40A) - Enables low-voltage drop during surge conduction, minimizing thermal stress and voltage overshoot.

Pinout & Package

GS3241-INE3 is housed in a RoHS-compliant DFN package measuring 1.6 mm × 1.6 mm × 0.55 mm with 6 leads and UL 94V-0 molding compound. The package supports high-density PCB layouts and requires direct connection of all pins for rated surge performance.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3	GND	Common ground return path; all three must be connected to minimize parasitic inductance and maximize 40A surge current handling.
4, 5, 6	IN	Protected line input (e.g., VBus in USB Type-C); all three pins are internally paralleled and must be tied together externally for full rating.

Key Features

Feature	Design Value
FET-based transient shunting	Replaces conventional TVS with active clamping: enables flat clamping voltage vs. current/temperature, unlike voltage-dependent V_BR + I_PP×R_DYN behavior.
Stable 27.5–28 V clamping	Maintains ≤28 V across −40°C to +125°C and 24–40A surge, ensuring consistent protection margin for 22V-rated controllers.
Low 20 mΩ dynamic resistance	Minimizes voltage rise during surge conduction, reducing thermal stress and enabling compact thermal design without heatsinking.
175 pF junction capacitance	Preserves signal integrity on 22V power rails while supporting fast transient response-no trade-off with high-frequency filtering.
DFN 1.6×1.6 mm footprint	Reduces board area by >50% versus legacy SO-8 or SOT-23 TVS solutions, critical for space-constrained USB Type-C and IoT modules.

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 1.6×1.6 mm package, identical marking (T22), and shared Semtech documentation-confirmed pin-to-pin and functional replacement.	No change in USB PD, load switch, or industrial 22V rail use cases; validated in same reference designs (e.g., Figure 4 & 5).	Select TDS2211P.C when sourcing directly from Semtech distribution channels or requiring traceable date-code marking per reel spec.
uClamp2411ZA	Lower working voltage (24 V), lower clamping (≈26 V), but higher capacitance (350 pF) and lower surge rating (30 A); not FET-based-uses silicon avalanche architecture.	Suitable only for CC/SBU lines in USB Type-C-not rated for 22V VBus or load-switch inputs due to lower IPP and unstable clamping above 25°C.	Choose uClamp2411ZA only for auxiliary signaling lines; avoid for GS3241-INE3's primary 22V power-rail role due to insufficient surge margin and thermal drift.

Compared with TDS2211P.C (identical replacement) and uClamp2411ZA (lower-performance alternative), GS3241-INE3 provides guaranteed 40A surge handling, stable 27.5–28 V clamping across temperature, and FET-based architecture-making it the optimal choice for 22V power-line protection where reliability under thermal and current stress is non-negotiable.

FAQ

What is the maximum clamping voltage of GS3241-INE3 under full-rated surge conditions?

The GS3241-INE3 clamps at 27.5–28 V when subjected to 40A peak pulse current (8/20μs) per IEC 61000-4-5, with RS = 2 Ω. This value is guaranteed across −40°C to +125°C and remains stable-unlike TVS diodes-due to its FET-based shunt architecture. The GS3241-INE3 datasheet specifies this clamping voltage as a design-critical parameter for protecting 22V-rated downstream ICs.

Does GS3241-INE3 require external biasing or control signals to operate?

No, GS3241-INE3 is a fully passive, self-triggering device. It contains an integrated precision trigger circuit and surge-rated FET-no external voltage, enable pin, or configuration is needed. When transient voltage exceeds the internal breakdown threshold (~25–27.9 V), the device automatically activates and shunts current to ground. The GS3241-INE3 functions immediately upon installation in the signal path without firmware or support components.

Can GS3241-INE3 be used on high-speed data lines like USB SuperSpeed or PCIe?

No, GS3241-INE3 is not intended for high-speed data lines. Its 175 pF junction capacitance is optimized for 22V power rails and low-frequency I/O protection-not signal integrity-critical differential pairs. For USB SS, DP/DM, or PCIe lanes, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25 pF). GS3241-INE3 should be applied only to VBus, CC, SBU, or load-switch inputs-not data paths.

What is the recommended PCB layout for GS3241-INE3 to achieve full 40A surge rating?

To achieve the full 40A rating, all three GND pins (1, 2, 3) and all three IN pins (4, 5, 6) must be shorted together on the PCB using wide, low-inductance traces. Place GS3241-INE3 within 5 mm of the protected connector. Use ≥4 vias per GND pin to a solid ground plane, and avoid routing sensitive traces near the device. These guidelines ensure minimal parasitic inductance-critical for GS3241-INE3's fast turn-on and energy dissipation.

Is GS3241-INE3 compliant with RoHS, REACH, and halogen-free standards?

Yes, GS3241-INE3 is Pb-free, halogen-free, and fully compliant with RoHS Directive 2011/65/EU and WEEE Directive 2012/19/EU. Its molding compound meets UL 94V-0 flammability rating, and lead finish is matte tin. Compliance is confirmed in Semtech's official documentation and supported by material declarations available through authorized distributors. GS3241-INE3 meets global environmental requirements for industrial and consumer electronics.
