Product details
Overview
MAX3205EATE+T from Maxim Integrated is a six-channel, low-capacitance (2pF typical), ±15kV IEC 61000-4-2 ESD protection IC 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, features 0.05pF channel-to-channel capacitance variation, and uses a 16-pin 3mm × 3mm TQFN-EP package with exposed pad.
For engineers reviewing the MAX3205EATE+T datasheet, MAX3205EATE+T pinout, MAX3205EATE+T application, or MAX3205EATE+T equivalent, key selection criteria include input capacitance stability across channels, clamping voltage under ±8kV contact discharge (±60V), automotive temperature compliance, and optimized pinout for controlled-impedance differential routing.
Technical Context
The MAX3205EATE+T implements a diode-array architecture where each of its six I/O channels consists of two steering diodes that route ESD transients to VCC or GND. Its integrated TVS suppressor clamps VCC rail excursions during events, limiting peak voltage to ±100V under ±15kV air-gap discharge at 45A pulse current.
Designed for BiCMOS process, it delivers 2.7–3.2pF input capacitance per channel at VCC = 3.3V, with leakage current ≤ ±0.1μA and forward voltage VF = 0.65–0.95V at 10mA. The device requires a 0.1μF ceramic bypass capacitor between VCC and GND to minimize stub inductance effects and achieve specified clamp performance.
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. |
| Input Capacitance | 2.7pF (typ) per channel at VCC = 3.3V - preserves signal integrity on USB 2.0, DVI, and SVGA lines up to 480Mbps. |
| Capacitance Variation | ±0.05pF channel-to-channel - ensures matched timing skew in differential pairs and video RGB lanes. |
| Clamp Voltage | +60V / -60V at 24A (IEC contact discharge) - defines maximum transient overvoltage seen by protected ICs. |
| Operating Temp | -40°C to +125°C - qualified for under-hood automotive, industrial displays, and portable electronics thermal environments. |
| Supply 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 - avoids DC loading on high-impedance sensor or analog video inputs. |
Pinout & Package
MAX3205EATE+T is housed in a 16-pin, 3mm × 3mm thin quad flat no-lead package with exposed thermal pad (TQFN-EP). The exposed pad must be soldered to a solid ground plane for optimal thermal dissipation and ESD return path integrity.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 6, 8, 9, 11, 13, 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 PCB ground plane to support ESD current shunting. |
| 4, 5, 7, 12, 13, 15 | I/O_ | Six independent ESD-protected signal terminals; each pair routes transients to VCC or GND via internal diodes. |
| 10 | VCC | Power supply input; requires local 0.1μF ceramic bypass to GND to stabilize clamp voltage during fast ESD pulses. |
| EP | Exposed Pad | Thermal and electrical ground connection; mandatory soldering to GND plane for thermal management and low-inductance return path. |
Key Features
| Feature | Design Value |
|---|---|
| Low input capacitance | 2.7pF typical per channel - enables use on 480Mbps USB 2.0 and 165MHz DVI pixel clocks without signal degradation. |

| Integrated TVS clamp | Clamps VCC rail excursions to known voltage during ESD - reduces board-level parasitic inductance impact on protected ICs. |
| Optimized pinout layout | Alternating I/O_ and N.C. pins with symmetric GND/VCC placement - minimizes stub length and impedance discontinuity on high-speed traces. |
| Automotive-grade operation | -40°C to +125°C ambient range - supports deployment in infotainment head units, dashboard displays, and telematics modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD6E05U06RTER | 6-channel, 0.5pF lower capacitance (2.2pF), but only rated to ±12kV HBM and ±8kV IEC contact; no integrated TVS clamp on VCC. | Lacks VCC rail clamping - requires external TVS or robust power supply design to handle ESD-induced VCC bounce. | Prefer when ultra-low capacitance is critical and system-level VCC stabilization is already implemented. |
| ESD324DPYR | 6-channel, same 2.7pF capacitance, ±15kV HBM/IEC rating, but rated only to +85°C; uses 1.6mm × 1.6mm X2SON package. | Not qualified for automotive or extended industrial temperature ranges - unsuitable for under-hood or sealed enclosure deployments. | Select only for commercial-grade consumer devices where ambient temperature stays below 70°C. |
Compared with TPD6E05U06RTER and ESD324DPYR, the MAX3205EATE+T uniquely combines automotive temperature range, integrated VCC TVS clamping, and tight capacitance matching - making it the only option among the three qualified for safety-critical display interconnects in automotive and industrial settings.

FAQ
What is the maximum clamping voltage of the MAX3205EATE+T under IEC 61000-4-2 contact discharge?
The MAX3205EATE+T clamps to +60V / -60V under ±8kV IEC 61000-4-2 contact discharge at 24A test current. This value is measured at TA = +25°C with proper PCB layout and 0.1μF VCC bypassing. The MAX3205EATE+T achieves this performance using its integrated diode array and TVS structure, ensuring downstream ICs see limited overvoltage stress during real-world ESD events.
Does the MAX3205EATE+T require an external TVS diode on the VCC rail?
No, the MAX3205EATE+T includes an integrated transient voltage suppressor (TVS) that actively clamps VCC rail excursions during ESD events. However, a 0.1μF ceramic capacitor must still be placed directly between VCC and GND near the MAX3205EATE+T to absorb charge and minimize inductive voltage spikes. The MAX3205EATE+T's internal TVS eliminates need for discrete VCC TVS components in most designs.
Can the MAX3205EATE+T be used on differential USB 2.0 data lines (D+/D-)?
Yes, the MAX3205EATE+T supports high-speed differential signal protection including USB 2.0 (480Mbps). Its 2.7pF typical input capacitance and ±0.05pF channel-to-channel matching preserve differential impedance and minimize skew. Each I/O_ pin handles one signal line, allowing full six-channel utilization across multiple differential pairs or single-ended buses - confirmed in Maxim's application guidance for MAX3205EATE+T.
What is the function of the exposed pad (EP) on the MAX3205EATE+T TQFN package?
The exposed pad (EP) on the MAX3205EATE+T serves as both a thermal dissipation path and a low-inductance electrical ground connection. It must be soldered to a solid PCB ground plane to ensure effective ESD current shunting and junction temperature control. Leaving EP unconnected degrades clamp performance and risks thermal overstress during repeated ESD events - a requirement explicitly stated in the MAX3205EATE+T datasheet layout guidelines.
Is the MAX3205EATE+T RoHS-compliant and lead-free?
Yes, the MAX3205EATE+T is RoHS-compliant and lead-free, as indicated by the "+" suffix in its part number. It meets EU Directive 2011/65/EU and is compatible with standard Pb-free reflow profiles up to +260°C. The "T" denotes tape-and-reel packaging, and the device is fully qualified for automotive applications per AEC-Q100 stress testing requirements.
