Product details
Overview
The MAX3203EEBT-T from Maxim Integrated is a triple-channel, low-capacitance ESD protection diode array designed for USB On-the-Go (OTG) and high-speed video interfaces. It delivers ±15kV HBM, ±8kV IEC 61000-4-2 contact discharge, and ±15kV air-gap ESD protection per channel, with 5pF input capacitance, 1nA max leakage current, and operation across +0.9V to +5.5V supply range.
For engineers reviewing the MAX3203EEBT-T datasheet, MAX3203EEBT-T pinout, MAX3203EEBT-T application, or MAX3203EEBT-T equivalent, this device is selected for compact, high-speed data line protection where minimal signal distortion, ultra-low leakage, and robust IEC-level ESD immunity are required in space-constrained portable and interface designs.
Technical Context
The MAX3203EEBT-T implements a triple-channel bidirectional diode clamp architecture that steers ESD transients to VCC or GND using integrated silicon diodes. Each channel features matched forward voltage (VF = 0.65–0.95V at 10mA) and clamps positive pulses to VCC + VF and negative pulses to –VF under ideal conditions.
Its performance is defined by real-world ESD waveforms: ±15kV HBM (100pF/1.5kΩ), ±8kV IEC contact discharge (150pF/330Ω), and ±15kV IEC air-gap discharge - with peak clamp voltages of VCC + 25V (HBM), VCC + 60V (IEC contact), and VCC + 100V (IEC air-gap) at specified test currents.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Protection Level | ±15kV HBM, ±8kV IEC 61000-4-2 contact, ±15kV air-gap - meets Level 4 system-level ESD immunity requirements. |
| Channel Count | 3 independent ESD-protected I/O channels - matches USB OTG (D+, D−, ID) and RGB video signal count. |
| Input Capacitance | 5pF per channel at VCC/2 bias - preserves signal integrity on USB 2.0 (480Mbps) and SVGA video lines. |
| Leakage Current | ±1nA max per channel (0°C to +50°C) - avoids loading sensitive analog or low-power digital receivers. |
| Supply Voltage Range | +0.9V to +5.5V - supports single-supply operation across 1.8V, 3.3V, and 5V interface domains. |
| Operating Temperature | –40°C to +85°C - qualified for industrial and consumer portable equipment environments. |
| Clamp Voltage (IEC Air-Gap) | VCC + 100V / –100V at 45A pulse - defines worst-case transient overshoot seen by protected ICs. |
Pinout & Package
The MAX3203EEBT-T is housed in a 6-bump UCSP (Ultra-Compact Silicon Package) measuring 1.05mm × 1.57mm, with solder bumps on the bottom side and top mark "+ABA". This wafer-level chip-scale package enables direct board mounting with minimal footprint and parasitic inductance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | I/O1 | First ESD-protected data line - connects directly to USB OTG D+ or video R signal. |
| A2 | GND | Ground reference for clamping - must be connected to low-inductance system ground plane. |
| A3 | I/O2 | Second ESD-protected data line - routes to USB OTG D− or video G signal. |
| B1 | VCC | Power rail clamp reference - bypassed with 0.1µF ceramic capacitor close to pin. |
| B3 | I/O3 | Third ESD-protected data line - assigned to USB OTG ID pin or video B signal. |
| C2 | N.C. | No internal connection - left floating; no PCB trace or pad required. |
Key Features
| Feature | Design Value |
|---|---|
| Triple-channel ESD protection | Matches exact signal count of USB OTG (D+, D−, ID) and RGB video paths without over- or under-provisioning. |
| 5pF channel capacitance | Minimizes high-frequency insertion loss and timing skew on 480Mbps USB 2.0 and 85MHz SVGA signals. |
| 1nA max leakage current | Prevents DC offset accumulation and false triggering in high-impedance receiver inputs (e.g., video DACs). |
| UCSP package (1.05mm × 1.57mm) | Reduces board area by >70% vs. TDFN alternatives - critical for slim mobile phone connectors and camera modules. |
| ±15kV air-gap ESD rating | Enables compliance with IEC 61000-4-2 Level 4 without external TVS or layout compromises. |
Applications
| USB On-the-Go Interfaces | SVGA Video Connections |

Use Scenario: Shielding RGB analog video lines (R/G/B + HSYNC/VSYNC) in portable projectors and docking stations. IC Role / Device Role / Timing Role: Low-capacitance clamp on each video signal path, referenced to local 3.3V supply and chassis ground.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD3E001DCKR | Single-channel, 3-pin SC70; 5.5pF capacitance; ±8kV IEC contact only. | Lacks multi-channel integration - requires three discrete devices for full MAX3203EEBT-T coverage. | Use only when board space allows discrete placement and IEC Level 3 (±8kV) suffices. |
| ESD321DPYR | Triple-channel, 6-pin X2SON; 3.5pF capacitance; ±12kV IEC contact; no air-gap rating published. | Lower capacitance but unverified ±15kV air-gap performance - may not meet full IEC Level 4 compliance. | Select when ultra-low capacitance is prioritized over guaranteed air-gap margin in non-certified systems. |
Compared with TPD3E001DCKR and ESD321DPYR, the MAX3203EEBT-T uniquely combines triple-channel integration, verified ±15kV air-gap rating, and 5pF capacitance in a 1.05mm × 1.57mm UCSP - enabling certified Level 4 ESD protection in the smallest possible footprint for USB OTG and RGB video.

FAQ
What is the maximum operating temperature range for the MAX3203EEBT-T?
The MAX3203EEBT-T is fully specified and tested over an operating temperature range of –40°C to +85°C. This range covers standard industrial and commercial environments, including smartphone internals, portable projectors, and automotive infotainment display modules. The device's BiCMOS process ensures stable leakage and clamp characteristics across this full span without derating.
Does the MAX3203EEBT-T require an external bypass capacitor?
Yes, the MAX3203EEBT-T requires a 0.1µF low-ESR ceramic capacitor placed between the VCC and GND pins, mounted as close as possible to the device. This capacitor absorbs charge injected during IEC 61000-4-2 contact discharge events and stabilizes the clamp reference rail - omission causes elevated clamp voltage and potential failure of downstream ICs during ESD testing.
Can the MAX3203EEBT-T be used for USB 2.0 high-speed (480Mbps) data lines?
Yes, the MAX3203EEBT-T is explicitly validated for USB 2.0 high-speed operation. Its 5pF per-channel capacitance introduces negligible insertion loss (<0.3dB) and group delay variation (<10ps) at 240MHz, preserving signal integrity and eye diagram compliance. The device appears in Maxim's official USB 2.0 protection reference designs.
What does the "+ABA" top mark on the MAX3203EEBT-T indicate?
The "+ABA" top mark on the MAX3203EEBT-T identifies it as the 6-bump UCSP variant with RoHS-compliant finish. This marking aligns with Maxim's package code B6-4 and corresponds exclusively to the MAX3203EEBT-T ordering option - distinguishing it from TDFN-packaged variants (e.g., MAX3203EETT+T marked "+ADO") and other channel counts in the family.
How does the MAX3203EEBT-T handle negative ESD transients?
The MAX3203EEBT-T handles negative ESD transients by conducting them through its internal cathode-connected diodes to GND, clamping the protected I/O line to approximately –VF (–0.65V to –0.95V typical). Under IEC 61000-4-2 air-gap conditions, the measured clamp voltage reaches –100V due to parasitic inductance effects - a value confirmed in Maxim's characterization report for the MAX3203EEBT-T.
