Product details
Overview
GX3290-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), 27.5–28V clamping voltage at 24–40A, and 20mΩ dynamic resistance. It protects USB PD, USB Type-C VBus, and load switch inputs in industrial and portable electronics.
For engineers reviewing the GX3290-CBE3 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability across temperature and current, low dynamic resistance, DFN-6 package layout constraints, and compatibility with 22V bus protection requirements in high-reliability interfaces.
Technical Context
The GX3290-CBE3 uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that turns on the shunt path when transient voltage exceeds breakdown. Unlike conventional TVS diodes, its clamping voltage remains nearly constant-27.5–28V-from 24A to 40A due to decreasing RDS(on) under surge conditions.
It operates over –40°C to +125°C with stable clamping performance, exhibits 175pF junction capacitance at 22V/1MHz, and maintains <600nA reverse leakage at VRWM. Its functional architecture enables superior thermal and current-handling consistency compared to standard TVS devices in high-energy EOS events.
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 24–40A (1.2/50μs + 8/20μs combo wave, RS = 2Ω) - ensures downstream ICs remain below damage thresholds during surges. |
| Peak Pulse Current | 40A (8/20μs) - supports compliance with IEC 61000-4-5 ±1kV (RS = 42Ω) industrial surge standards. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - provides robust system-level ESD immunity for exposed connectors. |
| Dynamic Resistance | 20mΩ - enables low-voltage drop during high-current transients, minimizing power dissipation in the device. |
| Junction Capacitance | 175pF at 22V, 1MHz - low enough for 22V power rail protection without signal integrity impact on adjacent traces. |
| Package | DFN 1.6mm × 1.6mm × 0.55mm, 6-lead - enables ultra-compact placement near USB Type-C or load switch inputs. |
Pinout & Package
Package: DFN-6 (1.6mm × 1.6mm × 0.55mm), Pb-free, RoHS-compliant, UL 94V-0 molding compound, tape-and-reel packaging (3,000 pcs/reel).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground terminals - all three must be connected to minimize parasitic inductance and maximize surge current handling. |
| 4, 5, 6 | IN | Protected line input - tied together to the 22V bus (e.g., USB PD VBus) to distribute surge current across parallel paths. |
Key Features
| Feature | Design Value |
|---|---|
| Constant clamping voltage across IPP range | 27.5–28V from 24A to 40A - eliminates design margin inflation needed with conventional TVS diodes. |
| Stable clamping over temperature | No increase in VC from –40°C to +125°C - enables reliable protection in automotive and industrial ambient conditions. |
| Low dynamic resistance | 20mΩ - reduces I²R heating and improves energy diversion efficiency during multi-pulse events. |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 5kHz & 100kHz) - protects against repetitive fast transients in noisy industrial environments. |
| Integrated FET-based architecture | Replaces discrete TVS + MOSFET solutions - reduces BOM count and PCB area vs. traditional active clamping designs. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20–22V VBus lines in USB-C receptacles subject to lightning-induced surges and connector hot-plug ESD. IC Role / Device Role / Timing Role: Primary EOS shunt protector placed between connector and PD controller or load switch input. Use Value: Maintains 27.5–28V clamping at full 40A surge, preventing damage to 24V-tolerant PD controllers even at 125°C ambient. |
Use Scenario: Safeguarding enable and input pins of high-side load switches (e.g., HS2950P) in remote meters and robotics. IC Role / Device Role / Timing Role: Front-end transient suppressor limiting voltage seen by internal FET gate oxide and drain-source junction. Use Value: Clamps below 30V during 8/20μs surges, avoiding gate oxide rupture and ensuring switch reliability over 10-year field life. |
| IoT Device Power Rail Protection | Notebook/Tablet DC Input Protection |
Use Scenario: Securing 12–22V DC input rails in battery-powered edge sensors and wireless gateways exposed to ESD and induced surges. IC Role / Device Role / Timing Role: Single-component solution replacing stacked TVS arrays for compact, cost-optimized board space. Use Value: Delivers ±30kV ESD and 40A surge capability in 1.6mm² footprint - critical for miniaturized IoT enclosures with limited heatsinking. |
Use Scenario: Hardening 20V adapter input stages in ultrabooks and tablets against AC-line coupled transients and user ESD. IC Role / Device Role / Timing Role: First-line defense before buck converter input capacitors and controller ICs. Use Value: 175pF capacitance avoids resonance with bulk input caps; stable clamping prevents brownout or latch-up during surge recovery. |
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" - direct Semtech-manufactured variant with same die and test flow. | No functional difference; used interchangeably in USB-C and industrial designs per Semtech's ordering documentation. | Select TDS2211P.C when requiring official Semtech traceability and standard reel packaging (3,000 pcs). |
| SMAJ22A | Standard unidirectional TVS diode; 22V VRWM, 35.5V VC @ 12.3A; higher clamping, no current-dependent flat response. | Limited to lower-energy surges; clamping rises to >40V at elevated temperature - unsuitable for 22V systems with tight margins. | Use only where cost is primary constraint and clamping >35V is acceptable; not recommended for USB PD or load switch inputs. |
Compared with TDS2211P.C, GX3290-CBE3 offers identical performance and form factor but may differ in date-code marking or distribution channel sourcing; versus SMAJ22A, GX3290-CBE3 delivers 12V lower clamping at full surge current and stable behavior across temperature-critical for 22V bus integrity.

FAQ
What is the exact clamping voltage specification for GX3290-CBE3 at 40A surge current?
The GX3290-CBE3 clamps at 27.6–28V under IEC 61000-4-5 combination waveform (1.2/50μs voltage + 8/20μs current, RS = 2Ω) at 40A peak pulse current. This value is guaranteed across –40°C to +125°C and reflects the device's FET-based architecture delivering near-constant voltage regardless of current magnitude within its rated range.
Is GX3290-CBE3 pin-compatible with TDS2211P.C?
Yes, GX3290-CBE3 is pin-compatible with TDS2211P.C: both use identical DFN-6 (1.6mm × 1.6mm) package with GND on pins 1–3 and IN on pins 4–6. Layout, solder mask, and thermal pad requirements are fully interchangeable, enabling direct substitution without PCB revision.
Does GX3290-CBE3 require external bias or control signals to operate?
No, GX3290-CBE3 is fully passive and autonomous - it requires no external power, enable signal, or configuration. The internal trigger circuit activates the shunt FET automatically when transient voltage exceeds its breakdown threshold, making GX3290-CBE3 suitable for always-on protection in unpowered or low-power states.
Can GX3290-CBE3 protect bidirectional data lines like USB DP/DM?
No, GX3290-CBE3 is designed exclusively for unidirectional 22V power or I/O line protection (e.g., VBus, load switch input). It is not rated for low-capacitance, bidirectional signal line protection; for DP/DM lines, Semtech recommends RClamp3371ZC (<0.25pF), not GX3290-CBE3.
What is the maximum operating temperature range for GX3290-CBE3?
GX3290-CBE3 is specified for continuous operation from –40°C to +125°C ambient temperature. Its clamping voltage and leakage current remain within datasheet limits across this full range, and junction temperature is rated to +150°C - supporting deployment in sealed industrial enclosures and automotive under-hood proximity.
