Product details
Overview
GS3470-IBTE3Z from Semtech is a Transient Diverting Suppressor (TDS) designed for high-energy EOS protection of 22V-rated power or I/O lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), 27.5–28V clamping voltage at 40A, 20mΩ dynamic resistance, and 175pF junction capacitance - deployed in USB PD, USB Type-C, and industrial load switch input protection.
For engineers reviewing the GS3470-IBTE3Z datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability across temperature and current, low dynamic resistance for flat VC vs. IPP behavior, DFN-6 package layout constraints, and compatibility with 22V bus systems requiring robust surge immunity per IEC 61000-4-5.
Technical Context
The GS3470-IBTE3Z uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that turns on the shunt FET when transient voltage exceeds breakdown threshold. Unlike conventional TVS diodes, its clamping voltage remains nearly constant over 24–40A and −40°C to +125°C due to decreasing RDS(on) under surge conditions.
It operates with reverse stand-off voltage of 22V, breakdown voltage of 25–27.9V at 1mA, and reverse leakage ≤600nA at VRWM. Its functional architecture separates trigger and conduction paths, enabling stable 27.5–28V clamping independent of pulse amplitude or ambient temperature - critical for USB PD bus integrity and load switch FET protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC operating voltage of protected line without leakage or conduction. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - ensures downstream ICs (e.g., USB PD controllers) remain below damage threshold during surge events. |
| 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) - provides robust handling-level ESD protection without degradation. |
| Dynamic Resistance | 20mΩ - enables flat clamping response and minimizes voltage rise across current range. |
| Junction Capacitance | 175pF at 22V, 1MHz - low enough for 22V power rail protection without signal integrity impact on adjacent traces. |
Pinout & Package
GS3470-IBTE3Z 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; thermal performance relies on PCB copper area and multiple vias to ground plane, not an exposed thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return path for surge current - all three pins must be connected to maximize current sharing and minimize parasitic inductance. |
| 4, 5, 6 | IN | Protected line input - connects directly to VBus or power/data line; all three pins must be tied together externally for full 40A rating. |
Key Features
| Feature | Design Value |
|---|---|
| Constant clamping voltage | 27.5–28V across 24–40A and −40°C to +125°C - eliminates derating concerns in thermally demanding environments. |
| FET-based shunt architecture | Surge-rated MOSFET + precision trigger circuit - replaces traditional TVS with lower dynamic impedance and superior thermal stability. |
| Low dynamic resistance | 20mΩ - reduces voltage overshoot during fast-rising transients and improves energy diversion efficiency. |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 100kHz/5kHz) - protects against repetitive burst noise in industrial control interfaces. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20–22V VBus lines in USB-C receptacles supporting up to 100W PD negotiation. IC Role / Device Role / Timing Role: Primary EOS suppressor placed between connector and PD controller or load switch input. Use Value: Maintains 27.5–28V clamping at 40A and 125°C - prevents PD controller latch-up or gate oxide damage where conventional TVS would exceed 35V. |
Use Scenario: Shielding HS2950P or similar load switches from lightning-induced surges in remote meters and robotics. IC Role / Device Role / Timing Role: Front-end transient diverter limiting voltage seen by internal FET drain-source junction. Use Value: Clamping below 28V ensures load switch RDS(on) FET remains within safe operating area during 1.2/50μs ±1kV surges (RS = 42Ω). |
| IoT Device Power Rail Protection | Storage Device 22V Backup Supply Protection |
Use Scenario: Securing 22V auxiliary rails in battery-backed smart sensors exposed to field ESD and conducted surges. IC Role / Device Role / Timing Role: Single-device solution replacing multi-stage TVS+MOV networks for space-constrained edge nodes. Use Value: 1.6mm × 1.6mm DFN footprint saves >60% board area versus discrete TVS + series resistor solutions while delivering higher IPP. |
Use Scenario: Safeguarding 22V supercapacitor or LiFePO₄ backup supplies in enterprise SSDs and NAS enclosures. IC Role / Device Role / Timing Role: Standby-mode protector maintaining <600nA leakage at 22V while ready to clamp 40A transients. Use Value: 130–600nA reverse leakage at VRWM ensures minimal self-discharge over months of standby operation. |
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 (T22), same tape-and-reel packaging (3,000/reel). | No functional difference - TDS2211P.C is the standard orderable variant; GS3470-IBTE3Z is a Semtech-marketed alternate part number for same die and assembly. | Select TDS2211P.C when sourcing via standard distributor channels; GS3470-IBTE3Z may reflect specific customer program or regional distribution labeling. |
| uClamp2411ZA | 24V working voltage, ±30kV ESD, but only 12A IPP (8/20μs), higher clamping (~33V), and 120pF capacitance. | Targeted for CC/SBU lines in USB-C, not main VBus - insufficient for 40A surge handling or 22V bus clamping stability. | Use uClamp2411ZA only for auxiliary signal lines; GS3470-IBTE3Z remains required for primary 22V power rail protection. |
Compared with TDS2211P.C (identical device) and uClamp2411ZA (lower-current signal-line suppressor), GS3470-IBTE3Z delivers verified 40A surge capability and flat 27.5–28V clamping essential for 22V power integrity - making it irreplaceable for VBus and load switch input protection where voltage margin is constrained.

FAQ
What is the exact package type and dimensions of GS3470-IBTE3Z?
GS3470-IBTE3Z uses a DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with 0.5mm pitch. Pin 1 is marked by a laser dot; terminals 1–3 are GND, and 4–6 are IN. The package is Pb-free, halogen-free, and RoHS/WEEE compliant with UL 94V-0 flammability rating.
Does GS3470-IBTE3Z meet IEC 61000-4-5 surge immunity standards?
Yes, GS3470-IBTE3Z is rated for 40A peak pulse current (8/20μs) and ±1kV (1.2/50μs, RS = 42Ω) per IEC 61000-4-5, making it suitable for Level 4 industrial surge protection on 22V lines. Its 27.5–28V clamping ensures compliance even at maximum stress levels.
How does GS3470-IBTE3Z differ from standard TVS diodes in clamping behavior?
Unlike standard TVS diodes whose clamping voltage rises linearly with current (VC = VBR + IPP × RDYN), GS3470-IBTE3Z maintains 27.5–28V clamping from 24A to 40A due to its FET-based shunt architecture and 20mΩ dynamic resistance - eliminating need for derating at high temperatures or currents.
Can GS3470-IBTE3Z be used for USB Type-C CC line protection?
No - GS3470-IBTE3Z is optimized for 22V power rail (VBus) protection and requires connection across high-current paths. For CC/SBU lines, Semtech recommends uClamp2411ZA (24V, low-capacitance, 12A), as GS3470-IBTE3Z's 175pF capacitance and 6-pin layout are unsuitable for differential signaling integrity.
What is the maximum operating temperature range for GS3470-IBTE3Z?
GS3470-IBTE3Z is specified for continuous operation from −40°C to +125°C ambient temperature. Its clamping voltage remains stable across this full range, and junction temperature can reach +150°C during transient events without performance degradation.
