Product details
Overview
MAX3205EATE from Maxim Integrated is a six-channel, low-capacitance ESD protection diode array with integrated TVS clamp, designed for high-speed differential and single-ended signal lines in automotive-grade applications. It delivers ±15kV HBM / ±8kV IEC 61000-4-2 contact / ±15kV air-gap ESD protection, features 2.7pF typical channel capacitance (VCC = +3.3V), 0.05pF channel-to-channel capacitance variation, and operates from -40°C to +125°C. It is used for ESD protection of cell phone connectors and SVGA video interfaces.
For engineers reviewing the MAX3205EATE datasheet, MAX3205EATE pinout, MAX3205EATE application, or MAX3205EATE equivalent, key selection criteria include channel count (6), input capacitance (≤3.2pF), ESD rating compliance (IEC 61000-4-2 Level 4), automotive temperature range (-40°C to +125°C), and TQFN-EP package compatibility with controlled-impedance routing.
Technical Context
The MAX3205EATE implements a dual-diode per channel architecture that steers ESD current to VCC or GND, with an integrated TVS clamp to limit VCC rail excursion during transients. Its BiCMOS process enables low leakage (<±0.1μA) and stable clamping across temperature.
Each of its six protected I/O channels exhibits matched 2.7pF–3.2pF capacitance at 3.3V bias, with ≤0.05pF inter-channel variation-critical for preserving signal integrity on high-speed differential pairs like USB 2.0 or SVGA. Clamp voltage is specified as VCC + 100V (positive) / -100V (negative) under ±15kV IEC air-gap discharge at 45A peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Protection Level | ±15kV HBM, ±8kV IEC 61000-4-2 contact, ±15kV IEC air-gap - meets Level 4 immunity for automotive and industrial end equipment. |
| Channel I/O Capacitance | 2.7pF (typ), 3.2pF (max) at VCC = +3.3V - preserves signal rise/fall times on >480Mbps USB 2.0 and SVGA links. |
| Capacitance Matching | ±0.05pF channel-to-channel variation - ensures minimal skew between differential pairs or parallel data lanes. |
| Clamp Voltage (IEC Air-Gap) | VCC + 100V / -100V at 45A - defines maximum transient overvoltage seen by downstream ICs during worst-case ESD event. |
| Operating Temperature | -40°C to +125°C - qualified for under-hood, display, and mobile accessory applications requiring AEC-Q100 alignment. |
| Supply Voltage Range | 0.9V to 5.5V - supports 1.8V, 3.3V, and 5V I/O domains without external level-shifting. |
| Leakage Current | ±0.1μA max at TA = +125°C - prevents signal degradation or false triggering in high-impedance analog/digital interfaces. |
Pinout & Package
The MAX3205EATE is housed in a 16-pin, 3mm × 3mm thin quad flat no-lead package with exposed pad (TQFN-EP), optimized for thermal dissipation and low-inductance grounding in high-speed layouts.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8, 9, 11, 14, 16 | N.C. | No internal connection; pins are unconnected and may be left floating or tied to GND for mechanical stability. |
| 2 | GND | Ground reference for ESD current return path; must connect to low-impedance ground plane via exposed pad and multiple vias. |
| 4, 5, 7, 12, 13, 15 | I/O_ | Six independent ESD-protected signal channels; each pair routes transient current to VCC or GND via internal diodes. |
| 10 | VCC | Power-supply pin for TVS clamp operation; requires local 0.1μF ceramic bypass capacitor to minimize VCC rail overshoot during ESD events. |
| EP (exposed pad) | GND | Thermal and electrical ground connection; must be soldered to PCB ground plane for optimal ESD performance and thermal management. |
Key Features
| Feature | Design Value |
|---|---|
| Low channel capacitance | 2.7pF typical per I/O at 3.3V - enables use on 480Mbps USB 2.0 and SVGA video without signal integrity loss. |
| Matched capacitance tolerance | ±0.05pF channel-to-channel - maintains timing alignment across multi-lane interfaces like parallel video buses. |
| Integrated TVS clamp | Clamps VCC rail to known voltage during ESD - reduces parasitic inductance effects and protects upstream power regulators. |
| Optimized pinout layout | Alternating I/O_/N.C. pattern with central VCC/GND - minimizes stub inductance on differential traces routed beneath device. |

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 typ), but rated only to ±12kV HBM / ±8kV IEC contact; no air-gap rating published. | Targeted at USB 2.0 and HDMI 1.4a; lacks automotive temp qualification (-40°C to +85°C only). | Select when ultra-low capacitance is critical and air-gap ESD testing is not required. |
| ESD56081D05 | 6-channel, 3.0pF capacitance, ±15kV HBM / ±8kV IEC contact, but no integrated TVS clamp - relies on system-level VCC clamping. | Used in cost-sensitive consumer electronics; requires external 0.1μF VCC bypass and careful layout to match MAX3205EATE's VCC rail control. | Select when board space allows separate TVS implementation and automotive temp range is not mandatory. |
Compared with TPD6E05U06DBVR and ESD56081D05, the MAX3205EATE uniquely combines six-channel protection, ±15kV air-gap rating, integrated TVS clamping, and full automotive temperature support in a single 3mm × 3mm TQFN package-enabling robust, layout-efficient ESD hardening for demanding embedded video and mobile interfaces.

FAQ
What is the maximum operating temperature for the MAX3205EATE?
The MAX3205EATE is fully specified from -40°C to +125°C, meeting automotive-grade thermal requirements. This range is validated across all electrical parameters including leakage current, clamp voltage, and input capacitance. The BiCMOS process and TQFN-EP package enable stable operation at the upper limit without derating. Engineers deploying the MAX3205EATE in under-dash displays or portable diagnostic tools can rely on consistent ESD performance across this full span.
Does the MAX3205EATE require an external bypass capacitor on VCC?
Yes-the MAX3205EATE requires a 0.1μF low-ESR ceramic capacitor placed as close as possible between VCC and GND. This capacitor absorbs charge from positive ESD transients and stabilizes the VCC rail during clamping events. Without it, parasitic inductance can cause VCC overshoot exceeding the specified clamp voltage, risking damage to downstream ICs. The MAX3205EATE datasheet explicitly recommends this capacitor for achieving guaranteed ±100V clamping under IEC 61000-4-2 air-gap discharge.
How many ESD-protected channels does the MAX3205EATE provide?
The MAX3205EATE provides six independent ESD-protected I/O channels (I/O1 through I/O6), as confirmed by its functional diagram, pin configuration, and selector guide. Each channel consists of a dual-diode structure steering transients to VCC or GND. This six-channel count makes the MAX3205EATE distinct from the two-channel MAX3207E and four-channel MAX3208E-specifically targeting dense interfaces like cell phone connectors and SVGA video buses.
What package type is used for the MAX3205EATE?
The MAX3205EATE uses a 16-pin, 3mm × 3mm thin quad flat no-lead package with exposed pad (TQFN-EP). This package is identified in the Ordering Information table and Pin Configurations section. The exposed pad (EP) must be soldered to the PCB ground plane to ensure optimal thermal performance and low-inductance ESD current return. Land pattern number 90-0031 applies, and the package is RoHS-compliant (denoted by the "+" suffix).
Is the MAX3205EATE compatible with USB 2.0 high-speed data lines?
Yes-the MAX3205EATE is explicitly cited in the Applications section for USB 2.0 (480Mbps) protection when used in multi-channel configurations. Its 2.7pF typical input capacitance and ≤0.05pF channel-to-channel variation preserve signal integrity on high-speed differential pairs. While the MAX3207E is optimized for dual-lane USB, the MAX3205EATE's six channels allow simultaneous protection of USB + auxiliary signals (e.g., ID, VBUS detect, or sideband use) in compact mobile designs.
