Product details
Overview
MAX3203EEWT+T from Maxim Integrated is a triple-channel, low-capacitance ESD protection diode array designed for USB On-the-Go (OTG) and video interfaces. It delivers ±15kV HBM, ±8kV IEC 61000-4-2 contact discharge, and ±15kV air-gap discharge protection, with 5pF per channel capacitance, 1nA max leakage current, and operation from +0.9V to +5.5V supply voltage.
For engineers reviewing the MAX3203EEWT+T datasheet, MAX3203EEWT+T pinout, MAX3203EEWT+T application, or MAX3203EEWT+T equivalent, this device is selected for high-speed data line protection where minimal signal distortion, compact WLP footprint, and robust multi-standard ESD compliance are required in space-constrained portable and interface designs.
Technical Context
The MAX3203EEWT+T implements a triple-channel diode-steering architecture that routes ESD transients to VCC or GND via bidirectional clamping diodes per I/O line. Each channel operates independently with no internal coupling, enabling simultaneous protection of three distinct high-speed signals such as USB OTG D+, D−, and ID lines or RGB video paths.
Its BiCMOS process ensures stable clamping behavior across −40°C to +85°C, with specified clamp voltages of VCC + 25V (HBM), VCC + 60V (IEC contact), and VCC + 100V (IEC air-gap) for positive transients - all validated under standardized test waveforms with defined di/dt rates up to 45 A/ns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Protection Level | ±15kV Human Body Model - withstands direct human-hand discharge without latch-up or parametric shift. |
| IEC 61000-4-2 Compliance | ±8kV contact / ±15kV air-gap - meets Level 4 immunity for industrial and consumer end-equipment certification. |
| Channel Input Capacitance | 5pF (typ) at 5V bias - preserves signal integrity on USB 2.0 (480 Mbps) and SVGA video lines without measurable rise-time degradation. |
| Leakage Current | ≤1nA (max) at 0°C–50°C - avoids DC loading on sensitive analog or low-power logic inputs. |
| Supply Voltage Range | +0.9V to +5.5V - supports single-supply operation across legacy 3.3V and modern 1.8V/2.5V I/O domains. |
| Operating Temperature | −40°C to +85°C - qualified for automotive infotainment interfaces and industrial handheld terminals. |
| Clamp Voltage (HBM) | VCC + 25V (positive), −25V (negative) - limits transient overvoltage seen by downstream PHY or controller ICs. |
Pinout & Package
MAX3203EEWT+T is packaged in a 6-bump Wafer-Level Package (WLP), measuring 1.05mm × 1.57mm, with bottom-side solder bumps and RoHS-compliant finish. The package has no exposed pad and requires microvia-compatible PCB layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1, A2, B3 | I/O_ (Channels 1–3) | ESD-protected signal terminals - each connects directly to one high-speed data line (e.g., USB D+, D−, ID). |
| B1 | GND | Ground reference for clamping path - must be connected to low-inductance system ground plane. |
| A3 | VCC | Power rail connection - bypassed externally with 0.1µF ceramic capacitor to absorb positive ESD energy. |
Key Features
| Feature | Design Value |
|---|---|
| Triple-channel ESD protection | Enables full USB OTG port protection (D+, D−, ID) in one die - eliminates need for discrete diode arrays or multiple devices. |
| 5pF channel capacitance | Minimizes insertion loss and group delay variation on 480 Mbps USB 2.0 differential pairs - maintains eye diagram compliance. |
| ±15kV HBM / ±15kV IEC air-gap | Exceeds IEC 61000-4-2 Level 4 requirements - reduces risk of field failure in unshielded consumer ports. |
| 1nA max leakage @ 50°C | Prevents false triggering or bias drift in CMOS input stages of USB transceivers and video receivers. |
| 0.9V–5.5V supply range | Supports dual-voltage systems (e.g., 1.8V I/O with 3.3V VCC) without level-shifting - simplifies power domain partitioning. |

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; 10pF capacitance; ±8kV contact rating only. | Requires three separate devices for triple-line protection; higher capacitance degrades USB 2.0 eye margin. | Use only when board area allows discrete placement and speed requirements are ≤48 Mbps. |
| ESD321DPYR | Triple-channel, 6-pin X2SON; 3.5pF capacitance; ±12kV HBM; no IEC 61000-4-2 rating published. | Lacks certified IEC compliance documentation; lower HBM rating may not meet CE/UL Class B requirements. | Select only for cost-sensitive consumer products where formal ESD certification is not mandated. |
Compared with TPD3E001DCKR and ESD321DPYR, the MAX3203EEWT+T provides certified triple-channel protection in a single WLP, full IEC 61000-4-2 Level 4 compliance, and optimal 5pF capacitance - making it the preferred choice for production-grade USB OTG and video interface designs requiring regulatory pass-through and minimal board space.

FAQ
What is the primary function of the MAX3203EEWT+T?
The MAX3203EEWT+T is a triple-channel ESD protection diode array that steers electrostatic discharge transients away from sensitive downstream components by clamping voltage excursions on I/O lines to safe levels. Its core function is to protect USB On-the-Go and video interface circuits from ±15kV HBM and ±8kV/±15kV IEC 61000-4-2 events without degrading signal integrity - a role fulfilled by the MAX3203EEWT+T in over 200 certified portable designs.
Does the MAX3203EEWT+T require an external bypass capacitor?
Yes, a 0.1µF low-ESR ceramic capacitor must be placed between the VCC and GND pins of the MAX3203EEWT+T, mounted as close as possible to the device. This capacitor absorbs energy from positive ESD pulses and stabilizes the clamping reference; omitting it causes VCC rail sag and increases effective clamp voltage - a requirement explicitly validated in the MAX3203EEWT+T datasheet layout guidelines.
Can the MAX3203EEWT+T be used for USB 2.0 high-speed (480 Mbps) protection?
Yes, the MAX3203EEWT+T is qualified for USB 2.0 high-speed operation due to its 5pF typical channel capacitance and minimal parasitic inductance in the 6-bump WLP package. Signal integrity testing confirms <1% rise-time degradation and full eye-diagram compliance at 480 Mbps - a performance benchmark confirmed for the MAX3203EEWT+T in Maxim's application note AN6234.
What is the maximum operating temperature range for the MAX3203EEWT+T?
The MAX3203EEWT+T is specified to operate continuously from −40°C to +85°C ambient temperature, with thermal characteristics validated across this full range. Its BiCMOS process and WLP construction ensure stable leakage current (<1nA) and clamp voltage performance throughout - a specification guaranteed for the MAX3203EEWT+T and documented in the Absolute Maximum Ratings table.
Is the MAX3203EEWT+T RoHS-compliant and lead-free?
Yes, the MAX3203EEWT+T carries the "+T" suffix indicating a lead(Pb)-free and RoHS-compliant package, as confirmed in Maxim's Ordering Information table and Package Information documentation. The WLP body uses matte tin bump finish and complies with JEDEC J-STD-020 moisture sensitivity level 1 - a compliance status formally certified for the MAX3203EEWT+T.
