Product details
Overview
MAX3203EETT+T from Maxim Integrated is a triple-channel ±15kV ESD protection diode array in a 6-pin TDFN-EP package, designed for USB On-The-Go (OTG) and high-speed video interfaces. It delivers 5pF per channel input capacitance, ≤1nA leakage current at +50°C, ±8kV IEC 61000-4-2 contact discharge rating, and operates from +0.9V to +5.5V supply voltage - enabling robust transient suppression on compact mobile and portable video signal paths.
For engineers reviewing the MAX3203EETT+T datasheet, MAX3203EETT+T pinout, MAX3203EETT+T application, or MAX3203EETT+T equivalent, this device is selected for high-speed data line protection where low capacitance, guaranteed triple-channel ESD clamping, and space-constrained PCB layouts are critical - especially in USB OTG, SVGA, and mobile connector designs requiring RoHS-compliant, exposed-pad thermal performance.
Technical Context
The MAX3203EETT+T implements a triple-diode array architecture with bidirectional steering: each I/O channel routes positive ESD transients to VCC via integrated forward-biased diodes and negative transients to GND via reverse-biased diodes. Its clamping behavior is defined by diode forward voltage (VF = 0.65–0.95V @ 10mA) plus supply rail voltage under positive pulses, yielding VC ≈ VCC + VF.
It operates across -40°C to +85°C, supports 0.1µF ceramic bypassing between VCC and GND, and relies on low-parasitic layout - including minimized trace inductance (L1/L2/L3) - to maintain effective clamp voltage during 1ns-rising 45A Air-Gap Discharge events. The exposed pad (EP) must be soldered to GND for thermal and electrical integrity.

Pinout & Package
MAX3203EETT+T is housed in a 6-pin TDFN-EP package (3mm × 3mm, 0.75mm height) with an exposed thermal pad (EP) that must be soldered to GND for optimal thermal dissipation and ESD return path integrity. Pin 1 is marked by a dot; the EP is electrically connected to GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | I/O1 | First ESD-protected signal line - routed directly from connector to protected IC input. |
| 2 | I/O2 | Second ESD-protected signal line - used for complementary or adjacent high-speed pair (e.g., USB D+). |
| 3 | I/O3 | Third ESD-protected signal line - supports ID pin in USB OTG or third video channel (e.g., Blue). |
| 4 | GND | Ground reference and primary ESD current sink - must connect to low-inductance system ground plane. |
| 5 | VCC | Power-supply input for positive transient clamping - requires 0.1µF ceramic bypass capacitor placed <1mm away. |
| 6 | N.C. | No internal connection - left unconnected; not used for signal or power routing. |
| EP | Exposed Pad | Thermal and electrical GND tie - must be soldered to PCB GND plane for θJC = 9°C/W and reliable ESD return path. |

Applications
| USB On-The-Go (OTG) | SVGA Video Interface |
|---|---|
|
Use Scenario: Protecting micro-AB receptacle pins (D+, D−, ID) on smartphones or tablets supporting host/peripheral role switching. IC Role / Device Role / Timing Role: ESD transient shunt - clamps ±15kV discharges before they reach the USB PHY transceiver. Use Value: Enables certified USB OTG functionality without compromising PCB real estate or signal bandwidth - 5pF capacitance maintains eye diagram integrity at 480Mbps. |
Use Scenario: Shielding RGB analog video lines (Red, Green, Blue) and sync signals from ESD during hot-plug of SVGA cables in portable projectors. IC Role / Device Role / Timing Role: Low-capacitance voltage clamp - limits transient overshoot to <±100V during air-gap discharge, preserving analog signal fidelity. Use Value: Prevents visible video artifacts (snow, streaks) caused by ESD-induced latch-up in display driver ICs - verified at 15kV air-gap. |
| Mobile Phone Connector | High-Speed Data Port |
|
Use Scenario: Safeguarding multi-function connectors (e.g., micro-USB or USB-C) handling data, audio, and charging in compact handsets. IC Role / Device Role / Timing Role: Triple-channel bidirectional ESD suppressor - routes transients to VCC/GND without affecting DC bias or AC coupling. Use Value: Supports concurrent USB 2.0, analog audio, and accessory detection on shared pins - 0.9V–5.5V supply range accommodates mixed-voltage signaling. |
Use Scenario: Hardening external I/O ports on embedded controllers or IoT gateways exposed to frequent human interaction. IC Role / Device Role / Timing Role: System-level ESD front-end - absorbs >45A peak current from IEC 61000-4-2 events while limiting voltage excursion to protected ICs. Use Value: Eliminates need for discrete TVS arrays or RC filters - single-component solution reduces layout complexity and improves time-to-certification. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD3F003DQAR | 3-channel, 5.5V max VCC, 0.5pF lower capacitance (4.5pF typ), no VCC pin - uses GND-only clamping architecture. | Requires no VCC rail; better suited for battery-powered systems with no local 3.3V/5V supply near connector. | Select when VCC is unavailable or when lowest possible capacitance is prioritized over dual-rail clamping headroom. |
| SP3003-03HTG | 3-channel, 5V max VCC, 6pF capacitance (max), ±12kV HBM only, no IEC 61000-4-2 certification data published. | Limited to HBM-rated environments; lacks documented IEC contact/air-gap validation - insufficient for CE/FCC certification-bound designs. | Acceptable only for cost-sensitive, non-certified internal modules where ±12kV HBM suffices and IEC testing is waived. |
Compared with TPD3F003DQAR and SP3003-03HTG, the MAX3203EETT+T uniquely combines IEC 61000-4-2 Level 4 compliance, VCC-assisted clamping for higher transient headroom, and production-validated 5pF performance - making it the preferred choice for certified USB OTG and portable video products requiring guaranteed ESD robustness.

FAQ
What is the maximum operating temperature range for the MAX3203EETT+T?
The MAX3203EETT+T is specified to operate reliably from -40°C to +85°C ambient temperature. This range is fully supported across all electrical parameters in the datasheet, including leakage current, clamp voltage, and ESD protection performance. Thermal design must account for the 42°C/W junction-to-ambient resistance of the TDFN-EP package to ensure junction temperature remains below +150°C under worst-case power dissipation.
Does the MAX3203EETT+T require an external bypass capacitor, and if so, where should it be placed?
Yes, the MAX3203EETT+T requires a 0.1µF low-ESR ceramic capacitor between VCC and GND. Per the datasheet layout guidelines, this capacitor must be placed within 1mm of the VCC (pin 5) and GND (pin 4) terminals to minimize loop inductance. Failure to place it correctly degrades clamp performance during IEC 61000-4-2 events, as the capacitor absorbs charge from +8kV contact discharge transients and stabilizes the VCC rail during positive ESD pulses.
Can the MAX3203EETT+T protect signals operating at 1.8V logic levels?
Yes, the MAX3203EETT+T supports supply voltages from +0.9V to +5.5V, making it fully compatible with 1.8V I/O domains. At 1.8V VCC, its positive clamp voltage is approximately VCC + VF ≈ 2.45V (using VF = 0.65V min), well within safe tolerance for 1.8V-tolerant receivers. The 5pF capacitance also ensures minimal impact on rise/fall times of 1.8V high-speed signals such as USB Full-Speed or camera interfaces.
Is the exposed pad (EP) on the MAX3203EETT+T electrically connected, and how must it be handled in layout?
Yes, the exposed pad (EP) on the MAX3203EETT+T is internally connected to GND and must be soldered to a dedicated PCB GND plane. It serves both thermal conduction (θJC = 9°C/W) and low-inductance ESD current return. Layout requires ≥90% solder paste coverage on the EP pad, connection to inner-layer GND planes via ≥4 thermal vias (0.3mm diameter), and avoidance of signal traces beneath the pad to prevent coupling.
How does the MAX3203EETT+T differ from the MAX3202EETT+T in terms of channel count and application fit?
The MAX3203EETT+T provides three ESD-protected channels versus two in the MAX3202EETT+T. This makes the MAX3203EETT+T the designated solution for USB On-The-Go (requiring D+, D−, and ID lines) and three-wire video interfaces, whereas the MAX3202EETT+T targets standard USB 2.0 (D+/D− only). Both share identical 5pF capacitance, ±15kV HBM rating, and TDFN-EP packaging - but channel count drives functional compatibility.
