Product details

Overview

GS1674-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 ESD immunity (IEC 61000-4-2), clamps at 27.5–28V under 40A 8/20μs surge, maintains <20mΩ dynamic resistance, and operates from –40°C to +125°C - enabling robust USB PD and industrial load switch input protection.

For engineers reviewing the GS1674-INE3 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 Type-C, IoT, and industrial equipment designs.

Technical Context

The GS1674-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 across 1–40A peak pulse current due to decreasing R_DS(on) under surge stress.

It features a 6-pin DFN (1.6 × 1.6 × 0.55 mm) with three parallel IN terminals (pins 4–6) and three parallel GND terminals (pins 1–3), requiring all six pins to be connected for full 40A rating and minimal parasitic inductance. Its 175pF junction capacitance at 22V is optimized for power-line-not high-speed data-line-protection.

Key Specifications

Parameter	Value and Actual Design Meaning
Working Voltage	22 V - matches nominal USB PD bus and industrial 24V rail systems without derating.
Clamping Voltage	27.5–28 V at 40A (8/20μs) - stays below 30V damage threshold of common load switches and PD controllers.
Peak Pulse Current	40 A (8/20μs) - satisfies IEC 61000-4-5 Level 4 surge immunity requirements for industrial equipment.
ESD Withstand	±30 kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD test mandates.
Dynamic Resistance	20 mΩ - ensures low voltage rise during surge conduction, minimizing energy dissipation in protected ICs.
Junction Capacitance	175 pF at 22 V, 1 MHz - suitable for power/bus line protection; not intended for >100 Mbps data lines.
Operating Temperature	–40°C to +125°C - supports extended-range operation in enclosed industrial and automotive under-hood environments.

Pinout & Package

GS1674-INE3 is housed in a Pb-free, RoHS-compliant DFN-6 package measuring 1.6 mm × 1.6 mm × 0.55 mm with exposed thermal pad (no solder mask defined). All six pins must be connected: pins 1–3 serve as parallel ground return paths, and pins 4–6 form a low-inductance, parallel input node for the protected line.

Pin/Terminal	Circuit Role	Design Meaning
Pins 1, 2, 3	GND	Parallel ground terminals - must all be connected to minimize ground loop inductance and sustain full 40A surge current.
Pins 4, 5, 6	IN	Parallel input terminals - connect directly to protected bus (e.g., VBUS in USB PD); shared path reduces trace inductance and improves surge sharing.

Key Features

Feature	Design Value
Constant-clamp architecture	Clamping voltage varies ≤0.5 V across 1–40A surge range - eliminates design margin inflation needed with traditional TVS diodes.
Temperature-stable clamping	Clamps at ~27.6 V at –40°C, 25°C, and 125°C - enables reliable protection without thermal derating calculations.
Low dynamic resistance	20 mΩ measured between 1A and 40A - reduces voltage overshoot during fast-rising transients (e.g., EFT bursts).
High-energy surge handling	1120 W peak pulse power (8/20μs) - supports repeated surge events in industrial metering and robotics applications.
DFN-6 space efficiency	1.6 mm × 1.6 mm footprint - saves >60% board area versus SO-8 or SOT-23 TVS solutions rated for equivalent surge current.

Applications

USB Type-C Power Delivery	Industrial Load Switch Input Protection
Use Scenario: Protecting VBUS lines in USB-C ports supporting up to 20V/5A PD negotiation against lightning-induced surges and connector hot-plug ESD. IC Role / Device Role / Timing Role: Transient diverting suppressor placed at connector entry point, shunting surge current to ground before it reaches PD controller or load switch. Use Value: Maintains clamping at ≤28 V across temperature and current range - prevents latch-up or gate oxide damage in downstream 24V-tolerant PD controllers.	Use Scenario: Safeguarding enable and input pins of industrial-grade e-fuses (e.g., TI TPS25940) against 1 kV/42 Ω surges per IEC 61000-4-5 in remote meters and PLC I/O modules. IC Role / Device Role / Timing Role: Primary front-end protector on VIN or EN rail, activated within nanoseconds to limit overvoltage before internal FET breakdown. Use Value: 40A surge rating and 20 mΩ R_DYN ensure sub-30V clamping even during worst-case 8/20μs transients - preserving load switch reliability over 10-year field life.
IoT Edge Node Power Bus	Robotic Actuator Control Supply
Use Scenario: Securing 22V auxiliary power rails in battery-backed smart sensors and gateway nodes deployed in unshielded outdoor enclosures. IC Role / Device Role / Timing Role: Standalone EOS protector on main DC input, coordinated with upstream fuse and downstream LDO. Use Value: ±30 kV ESD rating and –40°C to +125°C operation allow deployment in harsh environmental monitoring without external heatsinking or derating.	Use Scenario: Protecting motor driver supply inputs in collaborative robots where cable coupling induces repetitive 1–2 kV transients during actuator commutation. IC Role / Device Role / Timing Role: Low-inductance shunt device mounted adjacent to connector, routing surge energy away from gate drivers and MCU power domains. Use Value: Stable 27.6 V clamping at 125°C prevents thermal runaway in compact, sealed robot joints - eliminating need for oversized TVS arrays.

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 shared Semtech qualification - functionally identical part with alternate suffix convention.	No functional difference; used interchangeably in USB PD reference designs and industrial schematics.	Select TDS2211P.C when sourcing from authorized Semtech distributors with standard reel packaging (3,000 pcs/reel).
uClamp2411ZA.TCT	Zener-based TVS with 24 V working voltage, 33 V clamping at 12 A, 0.25 pF capacitance - higher clamping, lower surge rating, ultra-low capacitance.	Designed for CC/SBU lines in USB-C, not power rails; unsuitable for 40A surge handling or VBUS protection.	Choose uClamp2411ZA.TCT only for low-capacitance signal-line protection - not a replacement for GS1674-INE3 in power-bus roles.

Compared with TDS2211P.C (identical performance) and uClamp2411ZA.TCT (signal-line focused), GS1674-INE3 delivers purpose-built 22V power-rail protection with industry-leading 40A surge capacity and temperature-invariant clamping - making it the optimal choice for USB PD, industrial load switches, and high-reliability 22V bus applications.

FAQ

What is the maximum continuous operating voltage for GS1674-INE3?

The GS1674-INE3 has a reverse stand-off voltage (V_RWM) of 22 V, meaning it can continuously block up to 22 V DC without leakage exceeding 600 nA. This makes GS1674-INE3 suitable for nominal 20–22 V systems like USB PD 3.0 and industrial 24V rails with appropriate derating.

Does GS1674-INE3 require a thermal pad or heatsink?

No - GS1674-INE3 dissipates surge energy in its internal FET channel, not the silicon junction, so no thermal pad or external heatsink is required. The DFN-6 package relies on low-inductance PCB copper pour and multiple vias to ground for effective transient energy routing, as confirmed in Semtech's layout guidelines.

Can GS1674-INE3 be used on high-speed data lines like USB SuperSpeed or PCIe?

No - GS1674-INE3 has 175 pF junction capacitance at 22 V, which would severely degrade signal integrity on >100 Mbps differential buses. It is explicitly designed for power/bus line protection. For USB SS, DP/DM, or PCIe lanes, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25 pF).

How does GS1674-INE3 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), GS1674-INE3 uses a triggered FET to maintain clamping at ~27.6 V from 1 A to 40 A. This eliminates the need for over-specifying IPP to meet voltage thresholds - a key advantage in thermally constrained designs.

Is GS1674-INE3 compatible with lead-free reflow profiles?

Yes - GS1674-INE3 is qualified for standard IPC/JEDEC J-STD-020D lead-free reflow, with a maximum peak temperature of 260°C. Its DFN-6 package uses matte tin (Sn) lead finish and UL 94V-0 molding compound, fully compliant with RoHS and WEEE directives.
