Product details
Overview
GS2964-INTE3Z 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 full temperature range (−40°C to +125°C), enabling robust USB PD and industrial load switch input protection.
For engineers reviewing the GS2964-INTE3Z datasheet, pinout, applications, or equivalent options, this page provides verified electrical parameters, DFN-6 package layout guidance, functional role in surge diversion, and validated alternative options for 22V bus protection designs.
Technical Context
The GS2964-INTE3Z uses a precision-triggered shunt FET architecture instead of conventional PN-junction TVS diodes. Its trigger circuit activates the low-RDS(on) FET when transient voltage exceeds breakdown, achieving near-constant clamping voltage independent of peak pulse current magnitude or ambient temperature.
This architecture enables dynamic resistance as low as 20mΩ (8/20μs), junction capacitance of 175pF at 22V/1MHz, and reverse leakage under 600nA - all critical for maintaining signal integrity while diverting up to 1120W surge power without thermal runaway.
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) - ensures downstream ICs (e.g., USB PD controllers) remain below damage threshold during worst-case surges. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements with 2Ω source impedance. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD test levels without degradation. |
| Junction Capacitance | 175pF at 22V/1MHz - low enough to avoid signal distortion on 22V power rails but not suitable for high-speed data lines. |
| Dynamic Resistance | 20mΩ (8/20μs) - enables flat clamping curve by minimizing voltage rise (ΔV = I × R) across full 1–40A surge range. |
Pinout & Package
GS2964-INTE3Z is housed in a RoHS-compliant DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad (no solder mask defined). All six terminals are required for rated performance: pins 1–3 form a low-inductance ground path; pins 4–6 connect in parallel to the protected line.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return for surge current; must be connected to solid ground plane via multiple vias to minimize inductance. |
| 4, 5, 6 | IN | Parallel-connected input terminals for protected bus; all three must be routed together to ensure balanced current sharing and full 40A rating. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage remains ≤28V from 1A to 40A and −40°C to +125°C - eliminates derating calculations required for standard TVS diodes. |
| Surge-rated FET core | Shunt FET with sub-0.1Ω RDS(on) dissipates energy externally rather than in a PN junction - avoids thermal runaway under repeated surges. |
| Low dynamic resistance | 20mΩ measured between 1A and 40A (8/20μs) - ensures minimal voltage overshoot during fast-rising transients. |
| High-energy capability | 1120W peak pulse power (8/20μs) - supports long-duration lightning-induced surges common in industrial equipment interfaces. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting VBus lines in USB-C ports supporting up to 20V/5A PD negotiation against ESD and lightning-induced surges. IC Role / Device Role / Timing Role: Primary EOS shunt protector placed directly at connector, clamping transients before they reach PD controller or load switch. Use Value: Maintains 27.5–28V clamping across temperature and current range - prevents false overvoltage shutdowns and ensures compliance with USB-IF surge test requirements. |
Use Scenario: Safeguarding input terminals of industrial-grade load switches (e.g., HS2950P) in remote meters, robotics, and factory automation systems. IC Role / Device Role / Timing Role: Front-end transient diverter that limits voltage stress on internal FET gate oxide and drain-source junction during 1kV/42Ω surges. Use Value: Enables use of smaller, lower-cost load switches by preventing catastrophic failure during field-deployed surge events without requiring oversized components. |
| IoT Edge Node Power Rail Protection | Storage Device 22V Backup Supply Protection |
Use Scenario: Securing 22V auxiliary power inputs in battery-backed IoT gateways exposed to uncontrolled environments (e.g., outdoor smart sensors). IC Role / Device Role / Timing Role: Standalone EOS suppressor on primary DC input rail, coordinated with upstream fuse and downstream LDO. Use Value: Delivers 40A surge handling in 1.6×1.6mm footprint - reduces PCB area by >60% versus discrete TVS+MOV solutions while maintaining reliability. |
Use Scenario: Protecting 22V backup power supplies in enterprise SSDs and NVMe storage modules against hot-plug transients and board-level ESD. IC Role / Device Role / Timing Role: Low-capacitance (175pF) shunt device placed adjacent to power entry point to prevent latch-up in PMICs and flash controllers. Use Value: Reverse leakage <600nA at 22V ensures negligible standby current drain - critical for multi-year battery-backed storage retention. |
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; manufactured by Semtech with identical process and qualification. | No functional difference - used interchangeably in production; differs only in tape-and-reel packaging (3,000 pcs/reel vs. GS2964-INTE3Z's unspecified quantity). | Select TDS2211P.C when standard reel size and traceability per Semtech's ordering system are required. |
| uClamp2411ZA | 24V working voltage, ±30kV ESD, but rated for only 12A (8/20μs); uses standard TVS diode architecture with rising clamping voltage above 5A. | Suitable for CC/SBU lines in USB-C, not for 22V power rails - lacks current handling and flat-clamp behavior needed for GS2964-INTE3Z's target use cases. | Choose uClamp2411ZA only for low-current signal-line protection where space constraints preclude DFN-6 placement near connectors. |
Compared with TDS2211P.C, GS2964-INTE3Z offers identical protection performance and package; compared with uClamp2411ZA, it delivers 3.3× higher surge current capacity and thermally stable clamping - making it the sole viable option for 22V power rail EOS protection in demanding industrial and USB PD applications.

FAQ
What is the primary circuit function of the GS2964-INTE3Z?
The GS2964-INTE3Z functions as a transient-diverting suppressor that actively shunts high-energy electrical overstress (EOS) events-such as ESD, lightning surges, and EFT-to ground using a precision-triggered MOSFET. Unlike passive TVS diodes, GS2964-INTE3Z maintains a nearly constant clamping voltage of 27.5–28V across its full 40A surge rating and −40°C to +125°C operating range, ensuring predictable protection for sensitive 22V-system components.
Does the GS2964-INTE3Z require external bias or control signals to operate?
No, the GS2964-INTE3Z operates autonomously without external bias, enable pins, or configuration interfaces. Its internal trigger circuit monitors voltage across pins 4–6 relative to pins 1–3 and activates the shunt FET within nanoseconds when transient voltage exceeds the breakdown threshold. This self-contained operation makes GS2964-INTE3Z ideal for always-on protection in power rails where simplicity and reliability are critical.
Can the GS2964-INTE3Z be used on high-speed data lines like USB SuperSpeed or PCIe?
No, the GS2964-INTE3Z is not suitable for high-speed data lines due to its 175pF junction capacitance at 22V - which would severely degrade signal integrity above ~100MHz. It is explicitly designed for 22V power or low-frequency I/O lines. For USB SuperSpeed, DP/DM, or PCIe lanes, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25pF), not GS2964-INTE3Z.
How does the GS2964-INTE3Z compare to standard TVS diodes in thermal performance?
The GS2964-INTE3Z avoids junction heating issues inherent in standard TVS diodes by dissipating surge energy in the low-RDS(on) channel of its shunt FET rather than in a PN junction. As a result, GS2964-INTE3Z maintains stable clamping voltage and 40A surge capability across −40°C to +125°C, whereas typical 22V TVS diodes exhibit rising clamping voltage and reduced IPP rating above 85°C - making GS2964-INTE3Z uniquely suited for under-hood or industrial enclosure deployments.
What PCB layout practices are essential for achieving full 40A surge rating with the GS2964-INTE3Z?
To achieve the rated 40A (8/20μs) performance, all three GND pins (1–3) must connect to a solid ground plane using ≥3 thermal vias each, and all three IN pins (4–6) must be routed as a single low-inductance trace directly from the connector. GS2964-INTE3Z must be placed within 5mm of the protected interface; longer traces introduce parasitic inductance that elevates clamping voltage beyond the specified 28V limit during fast transients.
