Product details

Overview

GS3440-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 stable 27.5–28V clamping across temperature and current range. Used in USB Type-C PD input protection and load switch front-end safeguarding.

For engineers reviewing the GS3440-INTE3 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability under surge, low dynamic resistance (<20 mΩ), junction capacitance (175 pF), and DFN 1.6×1.6mm 6-lead thermal and layout performance.

Technical Context

The GS3440-INTE3 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 24A to 40A peak pulse current and −40°C to +125°C operating temperature.

This behavior stems from the FET's decreasing R_DS(on) under surge, yielding <20 mΩ dynamic resistance and eliminating the linear V_C = V_BR + I_PP × R_DYN dependency seen in pn-junction TVS devices. The device protects one bidirectional line with 22V reverse stand-off and 27.9V typical breakdown.

Key Specifications

Parameter	Value and Actual Design Meaning
Reverse Stand-Off Voltage	22 V - Maximum continuous operating voltage before conduction begins.
Clamping Voltage (I_PP = 40A)	27.6–28 V - Stable voltage limit during 40A 8/20μs surge; ensures downstream ICs remain below damage thresholds.
Peak Pulse Current	40 A (8/20μs) - Supports industrial ±1kV surge compliance (IEC 61000-4-5, R_S = 42Ω).
ESD Withstand	±30 kV contact & air (IEC 61000-4-2) - Eliminates need for cascaded ESD stages in USB-C and IoT interfaces.
Dynamic Resistance	20 mΩ - Enables low-voltage drop under surge, minimizing power dissipation and thermal stress.
Junction Capacitance	175 pF @ 22V, 1 MHz - Compatible with DC/low-speed power and control lines; not intended for >100MHz signal paths.
Operating Temperature	−40°C to +125°C - Validated clamping stability across full automotive and industrial ambient ranges.

Pinout & Package

GS3440-INTE3 is housed in a RoHS-compliant DFN package measuring 1.6 mm × 1.6 mm × 0.55 mm with exposed thermal pad (no internal thermal pad required). All six terminals must be connected per layout guidelines to achieve rated surge performance.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3	GND	Common ground return path for surge current; multiple vias recommended to minimize inductance.
4, 5, 6	IN	Protected line input - all three pins must be shorted externally to maximize current sharing and reduce impedance.

Key Features

Feature	Design Value
Constant-clamp architecture	Clamping voltage varies ≤0.5 V across 24–40A surge range and −40°C to +125°C - enables predictable system-level protection margin.
FET-based shunt topology	Replaces traditional TVS with active switching; eliminates thermal runaway risk and improves reliability under repeated surges.
Low dynamic resistance	20 mΩ ensures minimal IR drop during 40A transients - reduces localized heating and maintains voltage integrity at protected node.
High EFT immunity	±4 kV per IEC 61000-4-4 (5/50 ns, 100 kHz/5 kHz) - robust against burst noise in industrial motor drives and PLC I/O modules.
Space-optimized footprint	1.6×1.6 mm DFN saves >60% board area vs. comparable SO-8 or SOT-23 TVS solutions - critical for USB-C connector proximity placement.

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 shared Semtech qualification - functionally identical to GS3440-INTE3.	No functional difference; both qualified for USB-C PD and industrial load switch protection per same datasheet Rev 2.5.	Select GS3440-INTE3 for Aetrix inventory continuity; TDS2211P.C is direct manufacturer-equivalent with identical reel packaging (3,000 pcs/reel).
uClamp2411ZA	24V working voltage, lower 20A IPP rating, higher 33V clamping, and smaller 0.6×0.3mm 2-pin DFN - optimized for CC/SBU lines, not power rails.	Designed for low-capacitance (0.8 pF) data-line protection; unsuitable for 40A surge handling or 22V bus clamping requirements.	Use uClamp2411ZA only for auxiliary USB-C signals; GS3440-INTE3 remains mandatory for main V_Bus or load-switch input protection.

Compared with TDS2211P.C (identical spec) and uClamp2411ZA (lower IPP, higher clamp), GS3440-INTE3 uniquely delivers 40A surge capability with sub-28V clamping in a 1.6 mm² footprint - making it the only suitable choice for 22V power rail EOS hardening where thermal and layout constraints preclude larger packages.

FAQ

What is the maximum continuous operating voltage for GS3440-INTE3?

The GS3440-INTE3 has a reverse stand-off voltage (V_RWM) of 22 V, meaning it can continuously block up to 22 V DC or RMS without entering conduction. This makes GS3440-INTE3 suitable for 20V USB PD bus and 24V industrial control rails where nominal voltage stays within specification.

Does GS3440-INTE3 require a thermal pad on the PCB?

No, GS3440-INTE3 does not require an external thermal pad. Its DFN package dissipates surge energy through the GND pins (1–3) and IN pins (4–6); layout guidelines emphasize low-inductance grounding via multiple vias-not thermal mass. The GS3440-INTE3 datasheet explicitly states "no thermal pad is needed."

Can GS3440-INTE3 protect high-speed data lines like USB SuperSpeed?

No, GS3440-INTE3 is not intended for high-speed data lines. With 175 pF junction capacitance, it would severely degrade signal integrity on >100 MHz differential pairs. GS3440-INTE3 is specified for power and low-speed control lines; use RClamp3371ZC (<0.25 pF) for USB SS TX/RX lanes instead.

How does GS3440-INTE3 differ from standard TVS diodes in clamping behavior?

Unlike standard TVS diodes whose clamping voltage rises linearly with peak current (V_C = V_BR + I_PP × R_DYN), GS3440-INTE3 uses a triggered FET to maintain near-constant clamping (27.5–28 V) from 24A to 40A and across −40°C to +125°C - a key advantage confirmed in GS3440-INTE3's official characterization curves.

Is GS3440-INTE3 compliant with RoHS and halogen-free standards?

Yes, GS3440-INTE3 is Pb-free, halogen-free, and fully compliant with RoHS and WEEE directives. Its molding compound meets UL 94V-0 flammability rating, and lead finish is lead-free - all verified in the official Semtech TDS2211P datasheet applicable to GS3440-INTE3.
