Product details
Overview
GS4911BCNE3 from Semtech is a Transient Diverting Suppressor (TDS) designed for high-energy EOS/ESD 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 protection in USB PD, Type-C, and industrial load-switch inputs.
For engineers reviewing the GS4911BCNE3 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 where conventional TVS diodes exhibit rising clamping voltage with current or temperature.
Technical Context
The GS4911BCNE3 uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events. Unlike standard TVS diodes, its clamping voltage remains nearly constant across 1–40A (8/20μs) due to decreasing RDS(on) under surge conditions.
It operates from −40°C to +125°C with stable 27.5–28V clamping at 40A, 22V reverse stand-off voltage, and 175pF junction capacitance at 22V/1MHz - making it suitable for high-speed interfaces requiring low parasitic capacitance and predictable voltage limiting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - matches nominal USB PD bus and industrial 24V rail systems without derating. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - stays within safe margin below typical 30V IC damage thresholds. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds USB IF and IEC 61000-6-2 requirements. |
| Dynamic Resistance | 20mΩ - enables flat clamping curve and minimizes voltage overshoot during fast transients. |
| Junction Capacitance | 175pF at 22V/1MHz - low enough for USB PD CC/SBU lines but not superspeed data lanes. |
| Operating Temp | −40°C to +125°C - supports extended-range industrial and automotive under-hood applications. |
Pinout & Package
GS4911BCNE3 is housed in a Pb-free, RoHS-compliant DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with UL 94V-0 molding compound. All six terminals are surface-mount; no thermal pad required - energy is dissipated internally via the shunt FET.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return path for surge current; all three must be connected to maximize current handling and minimize inductance. |
| 4, 5, 6 | IN | Protected line input - connects directly to VBus or signal line; all three pins are electrically parallel and must be tied together externally. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based transient diversion | Replaces PN-junction TVS with active shunt switch, eliminating linear VC = VBR + IPP×RDYN rise. |
| Temperature-stable clamping | 27.5–28V clamping maintained across −40°C to +125°C - avoids thermal derating of protection margin. |
| Low dynamic resistance | 20mΩ ensures minimal IR drop during 40A surges, preserving voltage integrity on protected rails. |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 100kHz/5kHz) - protects against repetitive burst noise in motor drives and PLCs. |
| Space-optimized footprint | 1.6mm × 1.6mm DFN saves >60% board area vs. SO-8 or SOT-23 TVS solutions with comparable ratings. |
Applications
| USB Type-C Power Delivery | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting 20V–22V VBus lines in USB-C receptacles against lightning-induced surges and hot-plug ESD. IC Role / Device Role / Timing Role: Primary EOS suppressor placed between connector and PD controller or load switch input. Use Value: Maintains 27.5V clamping at full 40A surge - prevents latch-up or gate oxide damage in downstream 30V-rated controllers. |
Use Scenario: Shielding enable and input pins of industrial e-fuses (e.g., HS2950P) from 1kV/42Ω line surges. IC Role / Device Role / Timing Role: Front-end transient clamp upstream of overvoltage/overcurrent protection ICs. Use Value: Limits voltage seen by internal FETs to <28V, avoiding breakdown while sustaining 40A surge without thermal runaway. |
| IoT Edge Node Power Rails | Robotic Actuator Control Inputs |
|
Use Scenario: Securing 24V auxiliary power inputs on battery-powered gateways exposed to ESD during field servicing. IC Role / Device Role / Timing Role: Single-device solution for DC input port protection with minimal BOM count. Use Value: Delivers ±30kV ESD immunity and 40A surge rating in 2.56mm² footprint - critical for compact, sealed enclosures. |
Use Scenario: Guarding analog/digital control signals feeding servo drivers in factory automation systems. IC Role / Device Role / Timing Role: High-energy transient clamp on 22V logic supply rails feeding position feedback circuits. Use Value: Stable clamping ensures ADC reference stability and microcontroller reset integrity during EMC testing. |
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 | Same die, identical electrical specs, same DFN-6 package - only marking and reel packaging differ (TDS2211P.C is Semtech's standard orderable part). | No functional difference; used interchangeably in USB PD and industrial designs per Semtech documentation. | Select TDS2211P.C when sourcing directly from Semtech or authorized distributors with standard tape-and-reel logistics. |
| uClamp2411ZA | 24V working voltage, lower 24A peak pulse rating, higher 33V clamping at 24A, and 12pF capacitance - optimized for CC/SBU lines, not power rails. | Intended for low-capacitance data-line protection; unsuitable for 22V bus clamping due to higher VC and lower IPP. | Choose uClamp2411ZA only for auxiliary signal lines (CC, SBU); avoid for VBus or load-switch input protection. |
Compared with GS4911BCNE3, TDS2211P.C offers identical performance and drop-in compatibility, while uClamp2411ZA serves a different functional tier - low-capacitance signal-line protection - and cannot replace GS4911BCNE3 in power-rail applications without compromising surge margin.

FAQ
What is the exact package type and dimensions of GS4911BCNE3?
GS4911BCNE3 uses a 6-pin DFN package measuring 1.6mm × 1.6mm × 0.55mm with exposed copper terminals (no thermal pad). Pin 1 is marked by a laser dot; pins 1–3 are GND, and pins 4–6 are the parallel-connected IN terminal. The land pattern follows Semtech's recommended 0.30mm pad width and 0.50mm pitch.
Does GS4911BCNE3 meet IEC 61000-4-5 surge immunity standards?
Yes, GS4911BCNE3 is rated for 40A peak pulse current under the 8/20μs waveform per IEC 61000-4-5, and supports ±1kV combination-wave testing (1.2/50μs voltage + 8/20μs current, RS = 42Ω), satisfying Level 4 industrial surge immunity requirements.
How does GS4911BCNE3 differ from standard TVS diodes in clamping behavior?
Unlike TVS diodes whose clamping voltage rises linearly with current (VC = VBR + IPP×RDYN), GS4911BCNE3 maintains ~27.5–28V clamping from 1A to 40A due to its FET-based architecture and decreasing RDS(on). This eliminates thermal derating concerns and ensures consistent protection margin across operating temperatures.
Can GS4911BCNE3 be used on USB SuperSpeed differential pairs?
No - GS4911BCNE3 has 175pF junction capacitance, which would severely degrade signal integrity on USB 3.x/PCIe/DisplayPort lanes. For those lines, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25pF); GS4911BCNE3 is intended only for VBus, CC, SBU, or power-rail protection.
What is the maximum continuous reverse leakage current for GS4911BCNE3 at 22V?
At VRWM = 22V and TA = 25°C, GS4911BCNE3 exhibits reverse leakage current of 130–600nA. This ultra-low leakage preserves system efficiency in always-on IoT nodes and avoids false triggering in high-impedance monitoring circuits.
