Product details
Overview
GX3190-CBE3 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), and stable 27.5–28V clamping across temperature and current range. It protects USB Type-C power delivery buses, load switch inputs, and industrial interfaces where low, flat clamping voltage is critical.
For engineers reviewing the GX3190-CBE3 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, DFN-6 package layout guidance, functional role in surge-shunt architecture, and real-world use cases in USB PD and industrial load-switch protection.
Technical Context
The GX3190-CBE3 implements a precision-triggered shunt FET architecture - not a conventional TVS diode - enabling near-constant clamping voltage independent of peak pulse current (24A to 40A) and operating temperature (−40°C to +125°C). Its dynamic resistance is 20 mΩ, resulting in minimal voltage rise under surge.
It operates with reverse stand-off voltage (VRWM) of 22 V, breakdown voltage (VBR) of 25–27.9 V, and junction capacitance of 175 pF at 22 V/1 MHz. The device uses three parallel input terminals (Pins 4–6) and three ground terminals (Pins 1–3) to minimize parasitic inductance and maximize surge current handling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22 V - matches nominal USB PD bus and industrial 24V rail systems without derating. |
| Clamping Voltage | 27.5–28 V at 40A (8/20μs) - stays flat across full surge range, protecting downstream ICs below 28.5V absolute max. |
| ESD Rating | ±30 kV contact & air (IEC 61000-4-2) - exceeds Level 4 requirements for handheld and industrial interfaces. |
| Peak Pulse Current | 40 A (8/20μs) - meets IEC 61000-4-5 Line Surge Class 3 (±1 kV, RS = 42 Ω) with margin. |
| Dynamic Resistance | 20 mΩ - ensures minimal IR drop during surge, enabling predictable, low-voltage clamping behavior. |
| Junction Capacitance | 175 pF at 22 V - suitable for DC/low-speed power-line protection; not intended for high-speed data lines. |
| Package | DFN 1.6 × 1.6 × 0.55 mm, 6-lead - enables ultra-compact placement adjacent to connectors with minimal PCB area. |
Pinout & Package
Package: DFN 1.6 mm × 1.6 mm × 0.55 mm, 6-lead, Pb-free, RoHS-compliant, UL 94V-0 molding compound. Exposed thermal pad not required; energy dissipation occurs in silicon FET channel.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Parallel ground terminals - all must be connected to low-inductance ground plane via multiple vias for full 40A surge capability. |
| Pins 4, 5, 6 | IN | Parallel input terminals - connect directly to protected line (e.g., VBUS in USB-C); all three required for rated performance. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage remains ≤28 V from 24A to 40A and −40°C to +125°C - eliminates thermal derating uncertainty vs. TVS diodes. |
| Surge-rated FET core | Uses low-Rds(on) shunt FET activated by precision trigger circuit - avoids junction heating and voltage drift of pn-junction devices. |
| High-energy EFT immunity | Withstands ±4 kV per IEC 61000-4-4 (5/50 ns, 5 kHz & 100 kHz) - robust against repetitive fast transients in industrial environments. |
| Low-leakage protection | Reverse leakage ≤600 nA at 22 V - negligible impact on system quiescent current in always-on applications. |
| Compact DFN layout | 1.6 × 1.6 mm footprint saves >60% board space vs. SO-8 or SOT-23 TVS solutions with comparable ratings. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting VBUS lines in USB-C receptacles supporting up to 20 V/5 A PD negotiation, exposed to ESD and lightning-induced surges. IC Role / Device Role / Timing Role: Shunt-based transient suppressor placed between connector and PD controller or load switch input. Use Value: Maintains clamping at ≤28 V across temperature and surge magnitude - prevents damage to 28 V-tolerant PD controllers and e-fuses. |
Use Scenario: Securing input rails of industrial-grade load switches (e.g., HS2950P) in remote meters, robotics, and IoT gateways. IC Role / Device Role / Timing Role: Primary front-end EOS protector that limits voltage stress on internal FETs and OVP circuits. Use Value: Prevents latch-up or gate oxide rupture in load switches by clamping transients before they exceed 28 V absolute maximum rating. |
| Notebook/Tablet DC Power Input | Storage Device 24V Rail Protection |
|
Use Scenario: Safeguarding 20–22 V DC input stages in portable computing devices subject to user-handling ESD and adapter surge events. IC Role / Device Role / Timing Role: Standalone transient suppressor on main power entry point, upstream of buck converters and battery charge management ICs. Use Value: Enables compliance with IEC 61000-4-2/4-5 while eliminating need for oversized TVS arrays or complex multi-stage protection. |
Use Scenario: Protecting 24 V auxiliary rails in NVMe SSD enclosures, NAS units, and enterprise storage backplanes. IC Role / Device Role / Timing Role: Single-device solution for EOS suppression on power distribution nodes feeding PMICs and interface bridges. Use Value: Delivers 40 A surge handling in <2.6 mm² footprint - supports compact, fanless storage designs with high reliability targets. |
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; differs only in reel quantity (3,000 pcs vs. GX3190-CBE3's unspecified quantity). | No functional difference - validated drop-in replacement per Semtech ordering documentation and package drawings. | Select TDS2211P.C when standard 7″ tape-and-reel volume (3,000 pcs) aligns with procurement planning. |
| uClamp2411ZA | 24 V VRWM, lower IPP (20 A), higher clamping (~33 V), smaller 0.6 × 0.6 mm DFN-2 package - optimized for CC/SBU lines, not power rails. | Intended for low-capacitance, low-current signal-line protection - unsuitable for 40 A VBUS or load-switch input duty. | Use uClamp2411ZA only for auxiliary control lines; GX3190-CBE3 remains mandatory for primary power-rail surge suppression. |
Compared with TDS2211P.C (identical function and form) and uClamp2411ZA (lower rating, different application scope), GX3190-CBE3 provides the only validated 40 A, 22 V-rated DFN-6 solution with flat clamping - making it essential for high-reliability USB PD and industrial power-rail protection where surge margin and thermal stability are non-negotiable.

FAQ
What is the exact package type and dimensions of GX3190-CBE3?
GX3190-CBE3 uses a DFN package measuring 1.6 mm × 1.6 mm × 0.55 mm with 6 leads. Pin 1 is marked by a laser dot; pins 1–3 are GND, and pins 4–6 are IN. The land pattern follows Semtech's recommended layout with multiple vias to ground for optimal surge performance. This matches the mechanical specifications published in the TDS2211P datasheet Rev 2.5.
Does GX3190-CBE3 provide true constant-voltage clamping across temperature and current?
Yes - GX3190-CBE3 clamps at 27.5–28 V from 24 A to 40 A (8/20 μs) and across −40°C to +125°C, confirmed by Figure 3 and Table 2 in the TDS2211P datasheet. Unlike TVS diodes, its FET-based architecture maintains flat clamping due to decreasing Rds(on) under surge, not fixed dynamic resistance.
Can GX3190-CBE3 be used on high-speed data lines like USB SuperSpeed or PCIe?
No - GX3190-CBE3 has 175 pF junction capacitance at 22 V, making it unsuitable for high-speed differential data lines. It is designed exclusively for DC or low-frequency power and control lines. For USB SS/DP/DM lines, Semtech recommends RClamp3371ZC (<0.25 pF), not GX3190-CBE3.
What is the maximum continuous operating voltage for GX3190-CBE3?
The reverse stand-off voltage (VRWM) of GX3190-CBE3 is 22 V - meaning it can continuously block up to 22 V DC without conduction. Operating above this risks premature triggering. Its 25–27.9 V breakdown (VBR) and 28 V clamping define safe transient margins, but sustained bias must remain ≤22 V.
Is GX3190-CBE3 RoHS and REACH compliant?
Yes - GX3190-CBE3 is Pb-free, halogen-free, and compliant with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, as stated in the "Mechanical Characteristics" section of the TDS2211P datasheet Rev 2.5. Its molding compound also meets UL 94V-0 flammability rating.
