Product details
Overview
MAX3205EETE+ from Maxim Integrated is a six-channel, low-capacitance (2pF typical), ±15kV HBM/±8kV IEC 61000-4-2 contact/±15kV air-gap ESD protection diode array with integrated TVS clamp, designed for high-speed differential or single-ended signal lines in cell phone connectors and SVGA video interfaces. It operates from -40°C to +125°C and features channel-to-channel capacitance variation of only ±0.05pF.
For engineers reviewing the MAX3205EETE+ datasheet, MAX3205EETE+ pinout, MAX3205EETE+ application, or MAX3205EETE+ equivalent, this device delivers precise ESD clamping (±100V at 45A air-gap), ultra-low stub inductance via optimized TQFN-EP pinout, and automotive-grade reliability for HDMI/DVI/USB 2.0 port protection where signal integrity and layout-sensitive transient suppression are critical.
Technical Context
The MAX3205EETE+ integrates bidirectional steering diodes per channel that route ESD current to VCC or GND, combined with an on-chip TVS to clamp VCC rail excursion during transients. Its BiCMOS process enables tight capacitance matching and low leakage (±0.1μA).
Clamp voltage is defined by diode forward drop plus supply voltage for positive pulses (VC = VCC + VF) and –VF for negative pulses, with parasitic inductance directly amplifying effective clamp voltage-making low-inductance PCB routing essential. The device requires a 0.1μF ceramic bypass capacitor placed adjacent to the VCC pin to minimize VCC rail rise.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±15kV HBM, ±8kV IEC 61000-4-2 contact, ±15kV air-gap - meets Level 4 immunity for industrial and automotive end equipment. |
| Channel I/O Capacitance | 2.7pF (typical at VCC = +3.3V) - preserves signal integrity on 480Mbps USB 2.0 and DVI/HDMI links without measurable eye degradation. |
| Capacitance Variation | ±0.05pF channel-to-channel - ensures matched propagation delay across differential pairs and minimizes skew in high-speed video paths. |
| Clamp Voltage (Air-Gap) | ±100V at 45A peak - defines maximum overvoltage stress transferred to protected ICs; requires robust downstream device tolerance. |
| Supply Voltage Range | 0.9V to 5.5V - supports operation with 1.8V, 3.3V, and 5V I/O domains without level-shifting circuitry. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive, industrial displays, and portable electronics with extended thermal cycling. |
| Leakage Current | ±0.1μA max at TA = +25°C - prevents signal DC offset or bias shift in precision analog or high-impedance sensor interfaces. |
Pinout & Package
MAX3205EETE+ is housed in a 16-pin, 3mm × 3mm thin QFN with exposed pad (TQFN-EP). The package enables low thermal resistance and optimal RF grounding when the EP is soldered to a solid ground plane.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8, 9, 11, 14, 16 | N.C. | No internal connection; pins are electrically isolated and may be left floating or tied to GND for mechanical stability. |
| 2 | GND | Main ground reference; must connect to low-impedance ground plane to minimize return-path inductance for ESD current shunting. |
| 4, 5, 7, 12, 13, 15 | I/O_ | Six independent ESD-protected signal channels; each pair routes transients to VCC or GND via internal diodes. |
| 10 | VCC | Power-supply input for TVS clamp; requires local 0.1μF ceramic bypass to GND to suppress rail bounce during ESD events. |
| EP | Exposed Pad | Thermal and electrical ground connection; must be soldered to PCB ground plane to ensure thermal dissipation and low-inductance ESD return path. |
Key Features
| Feature | Design Value |
|---|---|
| Low input capacitance | 2.7pF typical per channel - avoids RC filtering of fast edges in HDMI 1.4 (165MHz pixel clock) and USB 2.0 (480MHz data rate). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD6E05U06DBVR | 6-channel, 0.5pF lower capacitance (2.2pF), but rated only to ±12kV HBM and ±8kV IEC contact; no integrated VCC clamp. | Lacks TVS functionality - requires external 5V TVS and additional PCB area; better suited for ultra-high-speed SerDes where sub-2.5pF is mandatory. | Select when absolute minimum capacitance is prioritized over integrated clamping and automotive temperature support. |
| ESD5451D05-2/TR | 6-channel, same ±15kV HBM/IEC ratings, but 3.5pF capacitance and no VCC clamp; uses SOT-23-6 package with higher inductance. | Higher channel capacitance degrades HDMI 2.0 eye margin; SOT-23 layout introduces >15% higher stub inductance vs. TQFN-EP. | Choose only for cost-sensitive consumer applications where 125°C operation and differential signal fidelity are not required. |
Compared with TPD6E05U06DBVR and ESD5451D05-2/TR, the MAX3205EETE+ uniquely combines automotive temperature range, integrated VCC TVS, and 2.7pF capacitance in a low-inductance TQFN-EP package-making it the only option qualified for high-reliability HDMI/DVI port protection in automotive infotainment systems.

FAQ
What is the maximum operating temperature for the MAX3205EETE+?
The MAX3205EETE+ is specified for continuous operation from –40°C to +125°C ambient temperature. This full automotive grade rating is validated across all electrical parameters in the datasheet, including leakage current, clamp voltage, and capacitance, ensuring reliable performance in under-dash infotainment systems and industrial HMIs where thermal management is constrained.
Does the MAX3205EETE+ require an external TVS diode?
No, the MAX3205EETE+ integrates a transient voltage suppressor (TVS) to clamp VCC rail excursions during ESD events. This eliminates the need for an external TVS, reducing BOM count and PCB area. However, a 0.1μF ceramic capacitor must still be placed directly between VCC and GND to absorb charge and stabilize the rail during fast transients.
How many ESD-protected channels does the MAX3205EETE+ provide?
The MAX3205EETE+ provides six independent ESD-protected I/O channels (I/O1 through I/O6), as confirmed by its functional diagram, pin configuration, and ordering information. Each channel consists of a pair of steering diodes that route ESD current to either VCC or GND, making it ideal for protecting multi-lane interfaces like SVGA RGB + sync or dual-link DVI.
What is the typical input capacitance per channel for the MAX3205EETE+?
The typical input capacitance per channel for the MAX3205EETE+ is 2.7pF at VCC = +3.3V and VI/O = VCC/2, as measured and guaranteed in the Electrical Characteristics table. This value is critical for maintaining signal integrity on high-speed interfaces such as USB 2.0 (480Mbps) and DVI (165MHz pixel clock), where excess capacitance causes edge rounding and jitter.
Is the MAX3205EETE+ RoHS-compliant and lead-free?
Yes, the MAX3205EETE+ is RoHS-compliant and lead-free, as indicated by the "+" suffix in its part number per Maxim's packaging nomenclature. The device meets EU RoHS Directive 2011/65/EU and is compatible with standard Pb-free reflow profiles up to +260°C peak temperature, verified in the Absolute Maximum Ratings section.
