Product details
Overview
GV8500-CNTE3 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, and 20mΩ dynamic resistance. It protects USB Type-C power delivery buses, load switch inputs, and industrial interfaces where stable clamping under temperature and current stress is critical.
For engineers reviewing the GV8500-CNTE3 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, DFN-6 package layout guidance, real-world USB PD and load switch protection use cases, and two validated alternative surge protectors with documented parameter differences.
Technical Context
The GV8500-CNTE3 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 across 24–40A (8/20μs) due to decreasing RDS(on) under surge conditions.
It operates from −40°C to +125°C with stable 27.5–28V clamping up to 125°C, 22V reverse stand-off voltage, 27.9V max breakdown, and 175pF junction capacitance at 22V/1MHz - enabling robust protection without signal integrity compromise in high-speed bus environments.
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 below 30V damage threshold of most 30V-rated load switches and PD controllers. |
| Peak Pulse Current | 40A (8/20μs) - satisfies IEC 61000-4-5 Level 4 surge immunity requirements for industrial equipment. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds Class 4 ESD immunity for exposed connectors and ports. |
| Dynamic Resistance | 20mΩ - ensures minimal voltage rise during high-current transients, preserving downstream voltage margins. |
| Junction Capacitance | 175pF at 22V/1MHz - low enough for DC power rails and medium-speed control lines; not suitable for >1Gbps data lanes. |
| Operating Temp | −40°C to +125°C - supports extended-temperature industrial, automotive under-hood, and outdoor IoT deployments. |
Pinout & Package
GV8500-CNTE3 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 full 40A surge rating: pins 1–3 serve as low-inductance ground return paths, and pins 4–6 form a parallel input node for the protected line.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | Ground (GND) | Three dedicated low-impedance ground terminals - must be connected to solid ground plane via multiple vias to minimize parasitic inductance during 40A surges. |
| Pins 4, 5, 6 | Input (IN) | Parallel-connected surge input nodes - connect directly to protected bus (e.g., VBUS in USB-C); all three must be routed together to maintain balanced current sharing. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based shunt architecture | Enables flat clamping voltage vs. current curve - avoids voltage runaway seen in TVS diodes under rising IPP. |
| Constant clamping over temperature | 27.5–28V clamping maintained from −40°C to +125°C - eliminates thermal derating calculations for industrial designs. |
| Low dynamic resistance | 20mΩ measured between 1A–40A (8/20μs) - minimizes IR drop and preserves voltage margin during worst-case surge events. |
| High-energy surge rating | 1120W peak pulse power (8/20μs) - supports repeated lightning-induced surges per IEC 61000-4-5 without degradation. |
| DFN-6 footprint | 1.6mm × 1.6mm area - saves >60% board space versus SO-8 or SOT-23 TVS solutions rated for comparable surge energy. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting the VBUS line of a USB-C port supporting up to 20V/5A PD negotiation against ESD, lightning surges, and hot-plug transients. IC Role / Device Role / Timing Role: Transient diverting suppressor placed immediately at the connector, clamping surges before they reach the PD controller or buck converter. Use Value: Maintains 27.5–28V clamping across −40°C to +125°C and 24–40A, preventing latch-up or gate oxide damage in 30V-rated PD ICs. |
Use Scenario: Safeguarding the input of an industrial-grade load switch (e.g., HS2950P) in remote metering or robotics systems exposed to 1kV/42Ω surges. IC Role / Device Role / Timing Role: Primary front-end surge clamp on VIN rail, limiting transient overvoltage to protect internal MOSFET gate oxide and overvoltage protection circuitry. Use Value: 40A surge handling and 20mΩ RDYN prevent voltage overshoot beyond the load switch's 30V absolute maximum rating during IEC 61000-4-5 testing. |
| IoT Edge Node Power Rail Protection | Storage Device 24V Backup Supply Protection |
|
Use Scenario: Securing the main 22V input rail of battery-backed IoT gateways deployed outdoors or in factory environments with high ESD and conducted surge risk. IC Role / Device Role / Timing Role: Single-point EOS protector on DC input, replacing multi-device TVS arrays while delivering superior clamping stability. Use Value: ±30kV ESD rating and 175pF capacitance allow direct placement on power entry without filtering distortion or startup delay. |
Use Scenario: Protecting the 24V auxiliary supply rail of enterprise SSDs or NAS enclosures against power-rail transients during hot-swap or grid fluctuation events. IC Role / Device Role / Timing Role: Clamping device on backup power input, ensuring transient energy is diverted before reaching PMIC or flash memory power regulators. Use Value: Stable 27.5–28V clamping prevents brownout or reset conditions in 3.3V/1.2V domain regulators downstream of the 24V rail. |
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 Semtech datasheet Rev 2.5 - confirmed pin-to-pin and functional replacement. | No difference; qualified for identical USB PD, load switch, and industrial use cases. | Select TDS2211P.C when sourcing from authorized Semtech distribution channels with full traceability and date-code visibility. |
| SMAJ22A | Standard unidirectional TVS diode; 22V VRWM, 35.5V VC @ 12.3A (8/20μs), 1.5Ω RDYN, 1500pF - higher clamping, lower surge rating, much higher capacitance. | Suitable only for low-speed, non-temperature-critical DC rails where 35.5V clamping is acceptable and 1.5kV surge compliance is sufficient. | Choose SMAJ22A only for cost-sensitive, non-automotive industrial applications with relaxed clamping and no high-temp operation. |
Compared with GV8500-CNTE3, TDS2211P.C offers identical performance and drop-in compatibility, while SMAJ22A trades 12× higher clamping voltage, 3× lower surge current, and 8.6× higher capacitance for lower unit cost - making it unsuitable for USB PD or thermally demanding load switch protection.

FAQ
What is the exact package type and dimensions of GV8500-CNTE3?
GV8500-CNTE3 uses a 6-pin DFN package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad. Pin 1 is marked by a laser dot; pins 1–3 are GND, pins 4–6 are IN. The land pattern requires full copper connection to ground plane with ≥3 vias per GND pin to ensure 40A surge capability. This footprint is identical to TDS2211P.C.
Does GV8500-CNTE3 meet IEC 61000-4-5 Level 4 surge immunity?
Yes, GV8500-CNTE3 is rated for 40A peak pulse current (8/20μs) and ±1kV combination wave (1.2/50μs voltage, 8/20μs current, RS = 42Ω), satisfying IEC 61000-4-5 Level 4 requirements for industrial equipment. Its 27.5–28V clamping ensures downstream components remain within safe operating voltage limits during full-level surges.
How does GV8500-CNTE3 differ from standard TVS diodes like SMAJ22A?
GV8500-CNTE3 uses a triggered FET shunt architecture, delivering near-constant 27.5–28V clamping from 24A to 40A and −40°C to +125°C. In contrast, SMAJ22A is a passive TVS with 35.5V clamping at 12.3A and rising clamping with temperature and current - making GV8500-CNTE3 superior for USB PD and thermally stressed industrial applications.
Can GV8500-CNTE3 be used on high-speed data lines like USB SS or PCIe?
No, GV8500-CNTE3 is not suitable for high-speed data lines. Its 175pF junction capacitance at 22V would severely degrade signal integrity above ~100MHz. It is intended exclusively for DC power rails and low-speed control lines. For USB SuperSpeed or DP/DM lines, Semtech recommends RClamp3371ZC (<0.25pF) instead of GV8500-CNTE3.
What is the maximum continuous power dissipation of GV8500-CNTE3?
GV8500-CNTE3 is not rated for continuous power dissipation - it is a transient-only protection device. Its Absolute Maximum Rating specifies 1120W peak pulse power (8/20μs), but steady-state power handling is limited by PCB thermal design. Under normal operation, reverse leakage is ≤600nA at 22V, resulting in <14nW static power - effectively zero DC loading on the protected bus.
