Product details
Overview
MAX3203EEBT from Maxim Integrated is a triple-channel ESD protection diode array designed for USB On-the-Go (OTG) and video interfaces. It delivers ±15kV HBM, ±8kV IEC 61000-4-2 contact, and ±15kV air-gap ESD protection with 5pF per channel capacitance, 1nA max leakage, and operation from +0.9V to +5.5V supply voltage.
For engineers reviewing the MAX3203EEBT datasheet, MAX3203EEBT pinout, MAX3203EEBT application, or MAX3203EEBT equivalent, this device is selected for high-speed data lines where low capacitance, robust ESD immunity, and compact UCSP packaging are critical-especially in space-constrained portable video and dual-role USB systems.
Technical Context
The MAX3203EEBT implements a triple-channel bidirectional diode clamping architecture that steers ESD transients to VCC or GND. Each channel uses paired diodes with forward voltage ≤0.95V at 10mA, enabling clamping to VCC + 0.95V for positive pulses and –0.95V for negative pulses under ideal conditions.
Its design targets IEC 61000-4-2 Level 4 compliance, limiting peak clamp voltage to ±60V under ±8kV contact discharge (24A pulse) and ±100V under ±15kV air-gap discharge (45A pulse), assuming minimal PCB parasitic inductance and proper 0.1µF VCC–GND bypassing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Protection Level | ±15kV HBM, ±8kV IEC contact, ±15kV IEC air-gap - meets IEC 61000-4-2 Level 4 for system-level ESD immunity |
| Channel Count | 3 independent ESD-protected I/O channels - supports USB OTG signal pairs (D+, D−, ID) or RGB video lines |
| Input Capacitance | 5pF per channel at 5V bias - preserves signal integrity on >480Mbps USB 2.0 and SVGA video links |
| Leakage Current | ≤1nA per channel at 0°C to +50°C - avoids DC loading of high-impedance data receivers |
| Supply Voltage Range | +0.9V to +5.5V - compatible with 1.8V, 3.3V, and 5V interface domains without level-shifting |
| Clamp Voltage | VCC + 60V (positive), –60V (negative) at 24A - defines worst-case overvoltage seen by protected IC during IEC contact discharge |
| Operating Temperature | –40°C to +85°C - qualified for industrial and consumer portable equipment environments |
Pinout & Package
The MAX3203EEBT is packaged in a 6-bump UCSP (1.05mm × 1.57mm), marked "+ABA", with exposed bump substrate requiring connection to GND per JEDEC J-STD-020A reflow guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | I/O1 | First ESD-protected bidirectional data line - routed directly from connector to protected IC input |
| A2 | GND | Ground reference for ESD current return path - must be low-inductance connection to system ground plane |
| B1 | I/O2 | Second ESD-protected bidirectional data line - used for complementary signal (e.g., USB D−) |
| B3 | I/O3 | Third ESD-protected bidirectional data line - supports ID pin in USB OTG or third video channel |
| A3 | VCC | Power-supply rail for positive clamping - requires local 0.1µF ceramic bypass capacitor to GND |
| C2 | N.C. | No internal connection - left floating or tied to GND per layout best practice to reduce stub inductance |
Key Features
| Feature | Design Value |
|---|---|
| Triple-channel ESD protection | Enables single-device protection of full USB OTG interface (D+, D−, ID) without discrete diode arrays |
| 5pF channel capacitance | Minimizes signal rise-time degradation on 480Mbps USB 2.0 and 80MHz SVGA pixel clocks |
| ±15kV HBM / ±8kV IEC contact | Exceeds EN 61000-4-2 Level 4 requirements for end-equipment certification |
| 1nA max leakage current | Prevents false triggering or bias shift in high-impedance analog video or USB receiver inputs |
| +0.9V to +5.5V supply range | Supports direct integration into mixed-voltage systems without external regulators or level shifters |
Applications

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, ±8kV IEC contact | Requires three devices for triple protection; larger total footprint than MAX3203EEBT UCSP | Choose when board layout favors discrete placement or legacy SC70 assembly lines are in use. |
| ESD321DPYR | Triple-channel, 6-pin X2SON (1.0mm × 1.0mm); 4.5pF, ±12kV IEC contact | Slightly smaller package but lower IEC rating; no VCC pin - clamps only to GND | Choose when system lacks clean VCC rail near connector or requires sub-5pF capacitance at cost of reduced ESD margin. |
Compared with TPD3E001DCKR and ESD321DPYR, the MAX3203EEBT provides integrated triple-channel protection in the smallest UCSP footprint, full VCC-referenced clamping for superior positive transient handling, and certified ±8kV IEC contact performance - making it optimal for USB OTG and compact video interfaces where layout area and ESD margin are co-constrained.

FAQ
What is the maximum operating temperature range for the MAX3203EEBT?
The MAX3203EEBT is specified to operate reliably from –40°C to +85°C ambient temperature. This range covers standard industrial and consumer portable equipment environments, including smartphones, projectors, and USB OTG accessories. The device's BiCMOS process and UCSP packaging maintain parametric stability across this full range without derating.
Does the MAX3203EEBT require an external bypass capacitor?
Yes, the MAX3203EEBT requires a 0.1µF low-ESR ceramic capacitor between its VCC and GND pins, placed as close as possible to the device. This capacitor absorbs charge from positive ESD transients and stabilizes the clamping reference. Without it, the effective clamp voltage can increase significantly - for example, a 24A IEC contact pulse may raise VC by up to 24V if the power supply has 1Ω output impedance.
Can the MAX3203EEBT protect USB 2.0 high-speed (480Mbps) signals?
Yes, the MAX3203EEBT is explicitly validated for USB 2.0 applications. Its 5pF per channel input capacitance introduces negligible signal distortion at 480Mbps, preserving eye diagram integrity and meeting USB-IF compliance margins. The device appears in Maxim's official selector guide for USB 2.0 ESD protection and is used in reference designs for OTG-enabled mobile platforms.
What does the top-mark "+ABA" indicate on the MAX3203EEBT package?
The top-mark "+ABA" identifies the MAX3203EEBT as a lead(Pb)-free, RoHS-compliant 6-bump UCSP device. The "+" prefix denotes RoHS status, while "ABA" is the unique wafer-level marking code assigned to this specific variant. This marking aligns with Maxim's package documentation (document #21-0097) and distinguishes it from TDFN or WLP versions of the MAX3203E family.
How does the MAX3203EEBT handle negative ESD transients?
The MAX3203EEBT handles negative ESD transients by conducting them through its internal cathode-grounded diodes to the GND terminal. Under ideal conditions (zero parasitic inductance), the clamp voltage is –VF (≤ –0.65V). In real layouts, parasitic inductance adds –L × di/dt, so a 10nH trace with a 45A/ns slew rate contributes –450V - underscoring the need for short, direct GND connections. The device's ±15kV air-gap rating confirms robust negative pulse handling capability.
