Product details

Overview

GS4910BCNE3 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 voltage at 40A, and 20mΩ dynamic resistance - enabling robust USB Type-C PD bus protection in industrial and portable systems.

For engineers reviewing the GS4910BCNE3 datasheet, pinout, applications, or equivalent options, this page provides verified electrical specifications, DFN-6 package layout guidance, real-world clamping stability across temperature and current, and validated alternatives for 22V EOS protection design.

Technical Context

The GS4910BCNE3 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) from 24A to 40A due to decreasing R_DS(on) under surge conditions.

It operates across –40°C to +125°C with stable 22V reverse stand-off voltage and <600nA leakage at VRWM. Its 175pF junction capacitance at 22V/1MHz and 20mΩ dynamic resistance support low-distortion protection of high-speed power rails without signal integrity compromise.

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 + 1.2/50μs combo wave) - 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 industrial surge immunity requirements for 22V systems.
ESD Withstand	±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD immunity standards for connector-facing protection.
Dynamic Resistance	20mΩ - enables flat clamping response and minimizes voltage overshoot during fast-rising transients.
Junction Capacitance	175pF at 22V/1MHz - low enough to avoid signal distortion on 20V power rails while maintaining robust surge handling.
Operating Temperature	–40°C to +125°C - supports deployment in extended-temperature industrial, automotive, and outdoor IoT environments.

Pinout & Package

GS4910BCNE3 is housed in a Pb-free, RoHS-compliant DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad (no internal thermal pad required per datasheet). All six terminals are surface-mount; pins 1–3 are tied internally to GND, pins 4–6 to IN - requiring external connection of all three GND and all three IN pads for full 40A rating.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3	GND	Common ground reference for trigger circuit and shunt FET source; must be low-inductance connection to PCB ground plane via multiple vias.
4, 5, 6	IN	Protected line input (e.g., VBUS in USB-C); all three pins must be paralleled to achieve rated 40A surge capability and minimize trace inductance.

Key Features

Feature	Design Value
FET-based transient diversion	Replaces traditional TVS diodes with active shunt architecture, delivering flat clamping independent of surge amplitude or temperature.
Constant clamping across current range	27.5–28V from 24A to 40A - eliminates need for overrating IPP to meet voltage safety margins in 22V systems.
Stable clamping over temperature	No increase in VC from –40°C to +125°C - enables reliable protection in thermally demanding enclosures without derating.
Low dynamic resistance	20mΩ - reduces I²R losses during surge, minimizing self-heating and preserving long-term reliability under repeated stress.
DFN-6 space efficiency	1.6mm × 1.6mm footprint - saves >50% board area vs. SO-8 or SOT-23 TVS solutions while supporting same 40A rating.

Applications

USB Type-C Power Delivery	Industrial Load Switch Input Protection
Use Scenario: Protecting 20V–22V VBUS lines in USB-C ports supporting up to 100W PD negotiation. IC Role / Device Role / Timing Role: Primary EOS suppressor placed directly at connector, shunting lightning-induced surges and ESD before reaching PD controller or load switch. Use Value: Maintains 27.5–28V clamping at full 40A even at 125°C - prevents controller latch-up or gate oxide damage where standard TVS would exceed 38V.	Use Scenario: Safeguarding input of high-side load switches (e.g., HS2950P) in remote meters, robotics, and factory automation equipment. IC Role / Device Role / Timing Role: Front-end transient limiter that clamps surges before they stress the load switch's internal MOSFET drain-source junction. Use Value: Keeps clamping voltage below 30V, ensuring it stays within the 30–35V absolute max rating of common 24V-rated load switches without derating.
IoT Edge Node Power Rails	Storage Device 22V Backup Supplies

IC Role / Device Role / Timing Role: Single-device solution for combined ESD, EFT (±4kV), and surge (±1kV) immunity per IEC 61000-4-2/4/5. Use Value: Eliminates need for multi-stage protection (TVS + MOV + filter), reducing BOM count and PCB area while guaranteeing coordinated clamping behavior.	Use Scenario: Protecting 22V supercapacitor or LiFePO₄ backup supplies in NVMe SSDs and enterprise storage controllers. IC Role / Device Role / Timing Role: Fast-acting shunt protector that responds within nanoseconds to prevent overvoltage damage during hot-swap or fault recovery events.

Equivalent & Alternatives

The following parts are listed as comparable options for similar transient suppression applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SMAJ22A	Standard unidirectional TVS diode; 35.1V clamping at 24.7A (8/20μs), 1.5× higher clamping than GS4910BCNE3 at same current.	Larger SMC package (7.1mm × 6.2mm); lacks flat clamping - VC rises with temperature and current.	Use only where cost is primary constraint and 35V+ clamping is acceptable for protected ICs.
TPD2E001DRYR	Low-capacitance (1.5pF) dual-channel ESD array; rated for 3A (8/20μs), not surge-grade - no IEC 61000-4-5 compliance.	Designed for data-line ESD only (e.g., USB D+/D−); insufficient for 40A power rail protection.	Complementary device only - pair with GS4910BCNE3 for full USB-C protection (power + data lines).

Compared with SMAJ22A and TPD2E001DRYR, GS4910BCNE3 uniquely delivers 40A surge capability with sub-28V clamping across temperature - making it the sole option among these three for protecting 22V power rails against combined ESD, EFT, and lightning surges in compact industrial designs.

FAQ

What is the exact clamping voltage of GS4910BCNE3 at 40A surge current?

The GS4910BCNE3 clamps at 27.5–28V when subjected to a 40A peak pulse current (8/20μs + 1.2/50μs combination waveform, RS = 2Ω), as specified in the Electrical Characteristics table of the official Semtech datasheet Rev 2.5. This value is guaranteed across –40°C to +125°C and does not increase with temperature or current magnitude - a key differentiator from standard TVS devices.

Does GS4910BCNE3 require a thermal pad on the PCB?

No, GS4910BCNE3 does not require an external thermal pad. The datasheet explicitly states "no 'thermal pad' is needed" because surge energy is dissipated through the active FET channel rather than a PN junction, and the DFN-6 package's thermal performance is sufficient for its 40A rating when pins 1–3 (GND) and 4–6 (IN) are properly connected with low-inductance traces and multiple vias to the ground plane.

Can GS4910BCNE3 be used to protect bidirectional data lines like USB DP/DM?

No, GS4910BCNE3 is designed exclusively for unidirectional 22V power or I/O line protection (e.g., VBUS, load switch inputs). Its pin configuration (IN/GND only) and 175pF junction capacitance make it unsuitable for high-speed data lines. For DP/DM protection, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25pF), not GS4910BCNE3.

How does GS4910BCNE3 compare to standard TVS diodes in temperature stability?

Unlike standard TVS diodes whose clamping voltage increases with temperature (e.g., +0.1V/°C typical), GS4910BCNE3 maintains a constant 27.5–28V clamping voltage from –40°C to +125°C. This is confirmed by Figure 3 and Table 1 in the datasheet, where VC shows no measurable drift across temperature - critical for industrial applications operating at elevated ambient temperatures.

Is GS4910BCNE3 RoHS and halogen-free compliant?

Yes, GS4910BCNE3 is fully RoHS/WEEE compliant and halogen-free, as stated in the Mechanical Characteristics section of the Semtech TDS2211P datasheet (Rev 2.5). It features lead-free termination, UL 94V-0 molding compound, and packaging in tape-and-reel format - meeting global environmental and safety requirements for industrial and consumer electronics.
