Product details
Overview
The MAX3206EETC-T from Maxim Integrated is a six-channel, low-capacitance ESD protection diode array designed to safeguard high-speed data I/O lines-including cell phone connectors and SVGA video interfaces-against ±15kV HBM, ±8kV IEC 61000-4-2 contact discharge, and ±15kV air-gap discharge events. It features 5pF per channel input capacitance, 1nA max leakage current, and operates from +0.9V to +5.5V supply voltage.
For engineers reviewing the MAX3206EETC-T datasheet, MAX3206EETC-T pinout, MAX3206EETC-T application, or MAX3206EETC-T equivalent, this device delivers verified ESD clamping performance (±100V at ±15kV air-gap), compact TQFN-EP packaging, and design-critical layout guidance for high-reliability interface protection in space-constrained portable electronics.
Technical Context
The MAX3206EETC-T implements a bidirectional diode-clamp architecture per channel, steering positive transients to VCC and negative transients to GND. Its clamping behavior is defined by forward diode voltage (VF ≈ 0.65–0.95V at 10mA) plus supply rail voltage or ground reference, with parasitic inductance effects explicitly modeled in its application guidance.
It requires external 0.1µF ceramic bypassing between VCC and GND to absorb charge from IEC-level ESD pulses, and relies on low-inductance PCB layout-especially short paths to GND/VCC-to maintain effective clamp voltage below ±100V during ±15kV air-gap discharge (IF = 45A).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Protection Level | ±15kV HBM, ±8kV IEC 61000-4-2 contact, ±15kV air-gap - meets IEC Level 4 compliance for end-equipment certification |
| Channel Count | 6 independent ESD-protected I/O channels - supports multi-line interfaces like SVGA (RGB+HSYNC+VSYNC) or multi-pin mobile connectors |
| Input Capacitance | 5pF per channel (typ) at VCC/2 bias - preserves signal integrity on >480Mbps USB 2.0 and VGA pixel clocks up to ~100MHz |
| Leakage Current | ±1nA max per channel (0°C to +50°C) - avoids DC loading of high-impedance sensor or analog video inputs |
| Clamp Voltage | +VCC + 100V / −100V peak under ±15kV air-gap (45A pulse) - defines maximum transient overvoltage seen by protected IC |
| Supply Range | +0.9V to +5.5V - compatible with 1.8V, 3.3V, and 5V logic domains without level-shifting |
| Operating Temp | −40°C to +85°C - qualified for industrial and consumer handheld operating environments |
Pinout & Package
The MAX3206EETC-T is housed in a 12-pin TQFN-EP package (4mm × 4mm, 0.75mm height) with exposed pad connected to GND for thermal and ESD return path integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 7, 8, 9 | I/O1–I/O6 | ESD-protected bidirectional signal terminals - each connects directly to a data line requiring transient suppression |
| 4, 6, 10, 12 | N.C. | No internal connection - must be left unconnected or grounded per layout best practice; no electrical function |
| 5 | VCC | Positive supply rail input - requires local 0.1µF ceramic bypass to GND to sink positive ESD current |
| 11 | GND | Ground reference and primary return path for negative ESD current - low-inductance connection critical |
| EP | Exposed Pad | Thermal and low-impedance GND connection - must be soldered to solid GND plane for optimal clamping and thermal dissipation |
Key Features
| Feature | Design Value |
|---|---|
| 6-channel integration | Reduces component count and board area vs. discrete diodes - enables single-chip protection for full SVGA RGBHV or 6-pin mobile docking interfaces |
| 5pF channel capacitance | Minimizes signal distortion and timing skew on high-speed differential and single-ended video/data lines |
| ±15kV air-gap rating | Supports robust front-panel ESD immunity without external spark gaps - simplifies enclosure design for handheld devices |
| 1nA max leakage | Prevents DC offset accumulation in analog video paths and avoids false triggering in high-impedance GPIO lines |
| TQFN-EP thermal design | θJA = 41°C/W and θJC = 6°C/W enable reliable operation at 70°C ambient with minimal heatsinking |

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, 5.5V VCC, 3.5pF typical capacitance, ±12kV contact discharge | Lower clamping voltage (±12V typ) but reduced ESD rating - suited for lower-threat environments | Preferred when tighter capacitance budget (<4pF) is required and IEC ±8kV suffices |
| SP3206-01UTG | 6-channel, 5.5V VCC, 6.5pF typical capacitance, ±15kV air-gap, μDFN package (2.5mm × 1.0mm) | Higher capacitance limits use on >200MHz signals; smaller footprint trades thermal performance for density | Chosen for ultra-compact designs where board space is more constrained than thermal headroom |
Compared with TPD6E05U06DBVR and SP3206-01UTG, the MAX3206EETC-T offers balanced performance: higher ESD rating than the TI part and lower capacitance than the Littelfuse part, making it optimal for certified industrial video and mobile docking applications demanding both robustness and signal fidelity.

FAQ
What is the maximum recommended trace length between the MAX3206EETC-T and the protected connector?
The MAX3206EETC-T datasheet specifies that trace inductance critically impacts clamping effectiveness. For ±15kV air-gap discharge (45A, 1ns dv/dt), even 10nH adds 450V to clamp voltage. Therefore, MAX3206EETC-T requires I/O traces ≤3mm long and direct routing to the connector pads, with GND/VCC vias placed within 0.5mm of each MAX3206EETC-T pin to minimize loop inductance.
Does the MAX3206EETC-T require external components to meet IEC 61000-4-2 Level 4 compliance?
Yes - the MAX3206EETC-T requires a 0.1µF low-ESR ceramic capacitor placed between VCC and GND, mounted within 1mm of the MAX3206EETC-T VCC and GND pins. This capacitor absorbs charge from ±8kV contact discharge events. Without it, the MAX3206EETC-T cannot maintain specified clamp voltage and may fail IEC testing.
Can the MAX3206EETC-T be used to protect 1.8V logic interfaces?
Yes - the MAX3206EETC-T operates from +0.9V to +5.5V, making it fully compatible with 1.8V systems. Its 1nA max leakage ensures negligible loading on 1.8V GPIO or I²C lines, and its ±15kV HBM rating protects low-voltage transceivers without requiring additional voltage translation.
How does the exposed pad (EP) of the MAX3206EETC-T affect ESD performance?
The exposed pad of the MAX3206EETC-T must be soldered to a solid GND plane to serve as the primary low-inductance return path for negative ESD current. Thermal resistance drops from 41°C/W to <10°C/W when properly connected, and clamping voltage stability improves by up to 30% compared to floating or undersized EP connections.
Is the MAX3206EETC-T RoHS-compliant and lead-free?
Yes - the MAX3206EETC-T carries the "+" suffix per Maxim's ordering nomenclature, indicating a lead(Pb)-free and RoHS-compliant package. Its TQFN-EP construction uses matte tin lead finish and complies with JEDEC J-STD-020 moisture sensitivity level 3 (MSL-3) for standard SMT assembly.
