Product details

Overview

GS4915-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 protects USB Type-C power delivery buses and load switch inputs in industrial and IoT equipment.

For engineers reviewing the GS4915-INE3 datasheet, pinout, applications, or equivalent options, this page provides verified electrical specifications, DFN-6 package layout guidance, real-world clamping behavior under surge conditions, and validated alternatives for 22V bus protection in USB PD and industrial power interfaces.

Technical Context

The GS4915-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 24A to 40A surge currents due to the FET's ultra-low dynamic resistance (20 mΩ).

It operates with reverse stand-off voltage of 22V, breakdown voltage of 25–27.9V, and junction capacitance of 175 pF at 22V/1MHz. Its thermal stability ensures consistent clamping performance from −40°C to +125°C, eliminating the voltage drift seen in standard TVS devices at elevated temperatures.

Key Specifications

Parameter	Value and Actual Design Meaning
Working Voltage	22V - defines maximum continuous DC operating voltage on protected line without leakage or conduction.
Clamping Voltage	27.5–28V at 40A (8/20μs) - limits transient voltage seen by downstream ICs, staying below typical 30V damage thresholds of USB PD controllers.
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) - exceeds automotive and industrial ESD requirements without external shielding.
Dynamic Resistance	20 mΩ - enables flat clamping curve; reduces voltage rise under increasing surge current versus TVS diodes.
Junction Capacitance	175 pF at 22V/1MHz - low enough for 22V power rail protection without signal integrity impact on DC or low-frequency control lines.
Operating Temp.	−40°C to +125°C - supports operation in harsh environments including industrial motor drives and outdoor IoT gateways.

Pinout & Package

GS4915-INE3 is housed in a Pb-free, RoHS-compliant DFN-6 package measuring 1.6 mm × 1.6 mm × 0.55 mm with UL 94V-0 molding compound. All six terminals are surface-mount; no thermal pad required.

Pin/Terminal	Circuit Role	Design Meaning
Pins 1, 2, 3	GND	Common ground return path for surge current; all three must be connected to maximize current handling and minimize inductance.
Pins 4, 5, 6	IN	Protected line input (e.g., VBUS or load switch input); parallel connection ensures uniform current sharing and optimal 40A rating.

Key Features

Feature	Design Value
FET-based clamping architecture	Delivers <28V clamping up to 40A with <20 mΩ dynamic resistance-enables predictable protection without voltage overshoot.
Temperature-stable clamping	Clamping voltage varies ≤0.5V from −40°C to +125°C-eliminates derating calculations needed for conventional TVS diodes.
High-energy surge capability	1120W peak pulse power (8/20μs)-supports repeated surges per IEC 61000-4-5 without degradation.
Low leakage & high isolation	600 nA max reverse leakage at 22V-prevents standby power loss in battery-powered IoT nodes and portable devices.
Compact DFN footprint	1.6 mm × 1.6 mm area-replaces larger SO-8 or SOT-23 TVS solutions while improving PCB routing density near connectors.

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 code "T22" - direct Semtech second-source variant with same tape-and-reel packaging (3,000 pcs/reel).	No functional difference; used interchangeably in USB-C and industrial designs where Semtech part numbering conventions apply.	Select when sourcing from authorized Semtech distribution channels requiring exact orderable suffix ".C".
uClamp2411ZA.TCT	Zener-based TVS with 24V working voltage, 35V clamping at 1A, higher dynamic resistance (>1Ω), and ±30kV ESD only-no 40A surge rating.	Suitable for CC/SBU lines in USB-C but not for 22V VBUS or load switch inputs due to insufficient energy handling and voltage drift with temperature.	Use only for low-current signaling lines; avoid for power rail protection where GS4915-INE3's flat clamping and 40A rating are required.

Compared with TDS2211P.C (identical function and form) and uClamp2411ZA.TCT (lower-energy Zener TVS), GS4915-INE3 offers superior surge robustness and thermal stability-making it the only choice among the three for protecting 22V power rails subject to IEC 61000-4-5 Level 4 surges in industrial and USB PD systems.

FAQ

What is the primary protection function of the GS4915-INE3?

The GS4915-INE3 functions as a transient diverting suppressor that shunts high-energy EOS events-including ESD, EFT, and lightning-induced surges-to ground using an integrated surge-rated FET. Unlike TVS diodes, it maintains a stable 27.5–28V clamping voltage across its full 40A surge rating and −40°C to +125°C operating range, making GS4915-INE3 ideal for protecting sensitive 22V power rails in USB PD and industrial systems.

Does GS4915-INE3 require a thermal pad on the PCB?

No, GS4915-INE3 does not require a thermal pad. Its DFN-6 package dissipates surge energy internally through the FET channel, and the datasheet explicitly states "no thermal pad is needed." Instead, design best practice requires connecting all three GND pins (1, 2, 3) and all three IN pins (4, 5, 6) with low-inductance traces and multiple vias to the ground plane-ensuring optimal 40A surge current handling without thermal derating concerns for GS4915-INE3.

How does GS4915-INE3 differ from standard TVS diodes in clamping behavior?

Standard TVS diodes exhibit linear clamping voltage rise with increasing peak pulse current (VC = VBR + IPP × RDYN), and their clamping degrades with temperature. In contrast, GS4915-INE3 uses a triggered FET architecture that holds clamping voltage nearly constant-27.5–28V-from 24A to 40A and across −40°C to +125°C. This behavior is confirmed by GS4915-INE3's 20 mΩ dynamic resistance and published clamping curves, enabling reliable protection without margin stacking.

Can GS4915-INE3 be used on USB SuperSpeed data lines?

No, GS4915-INE3 is not suitable for USB SuperSpeed (SS) differential pairs (TX/RX) due to its 175 pF junction capacitance, which would severely degrade signal integrity at 5+ Gbps. It is intended exclusively for 22V power or single-ended control lines. For SS lines, Semtech recommends low-capacitance TVS devices like RClamp3371ZC (<0.25 pF); GS4915-INE3 serves only the VBUS, CC, SBU, or load switch input-never high-speed data paths.

What is the marking code and packaging format for GS4915-INE3?

GS4915-INE3 is marked with "T22" followed by a two-digit date code (e.g., "T2223") and features a laser dot indicating Pin 1 location. It ships in tape-and-reel format with 3,000 units per 7-inch reel-matching the packaging specification of its Semtech counterpart TDS2211P.C. The device is Pb-free, halogen-free, and RoHS/WEEE compliant, with UL 94V-0 flammability rating.
