Product details
Overview
MAX3204EEWT+T from Maxim Integrated is a quad-channel, low-capacitance ESD protection diode array designed to safeguard high-speed data lines in Ethernet and FireWire® interfaces. It delivers ±15kV HBM, ±8kV IEC 61000-4-2 contact, and ±15kV air-gap ESD protection, features 5pF per channel input capacitance, 1nA max leakage current, and operates from +0.9V to +5.5V supply voltage.
For engineers reviewing the MAX3204EEWT+T datasheet, MAX3204EEWT+T pinout, MAX3204EEWT+T application, or MAX3204EEWT+T equivalent, key selection criteria include channel count (4), ultra-low capacitance for signal integrity, IEC/USB-compliant ESD robustness, WLP package footprint constraints, and compatibility with 3.3V/5V interface rails.
Technical Context
The MAX3204EEWT+T implements a bidirectional diode-steering architecture that routes ESD transients to VCC or GND depending on polarity. Each of its four protected I/O channels uses a pair of silicon diodes with clamping voltages of VCC + 25V (positive) and –25V (negative) under ±15kV HBM stress.
It requires external 0.1µF ceramic bypassing between VCC and GND to absorb transient energy during IEC 61000-4-2 events. Its 6-bump WLP package (1.05mm × 1.57mm) places all four I/O terminals, VCC, and GND on bottom-side bumps with no NC pins - enabling minimal trace inductance for optimal ESD suppression.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Protection Level | ±15kV HBM, ±8kV IEC contact, ±15kV IEC air-gap - meets Level 4 immunity per IEC 61000-4-2 |
| Channel Count | 4 independent ESD-protected I/O lines - matches Ethernet (10/100/1000BASE-T) PHY differential pairs |
| Input Capacitance | 5pF per channel at VCC/2 bias - preserves signal integrity up to 480Mbps USB 2.0 and 100MHz Ethernet |
| Leakage Current | ≤1nA per channel at 0°C–50°C - avoids DC loading on high-impedance receiver inputs |
| Supply Voltage Range | +0.9V to +5.5V - supports 1.8V, 3.3V, and 5V logic families without level-shifting |
| Operating Temperature | –40°C to +85°C - qualified for industrial and commercial Ethernet/FireWire endpoint environments |
Pinout & Package
MAX3204EEWT+T is packaged in a 6-bump Wafer-Level Package (WLP), measuring 1.05mm × 1.57mm, with bottom-side solder bumps and no exposed pad. The package supports reflow soldering and complies with RoHS requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1, A2, B2, B3 | I/O_ | Four ESD-protected signal terminals - each connects directly to one high-speed data line (e.g., TX+/TX–/RX+/RX–) |
| B1 | GND | Ground reference for ESD current return path - must be connected to low-inductance system ground plane |
| A3 | VCC | Power-supply rail for positive clamping - requires local 0.1µF ceramic bypass capacitor to GND |
Key Features
| Feature | Design Value |
|---|---|
| Quad-channel ESD protection | Enables full differential-pair protection for 100BASE-TX or FireWire 400 physical layer interfaces |
| 5pF channel capacitance | Minimizes signal distortion and insertion loss on >100MHz data lines without requiring layout compensation |
| ±15kV IEC air-gap rating | Validates robustness against real-world electrostatic discharge events near connectors and cables |
| 1nA max leakage | Prevents false triggering or bias shift in CMOS receiver inputs with high input impedance |
| 0.9V–5.5V supply range | Allows direct integration into mixed-voltage systems without dedicated ESD power domain |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP3204-01UTG | 4-channel, 5.5pF capacitance, ±12kV contact discharge, SOT-553 package (2.1mm × 1.6mm) | Larger footprint and higher capacitance limit use in >200MHz interfaces; lacks ±15kV air-gap rating | Select when board space allows larger package and IEC contact discharge ≥±12kV suffices |
| ESD401-4BF | 4-channel, 3.5pF capacitance, ±15kV HBM only, 0.9mm × 1.3mm WLCSP package | No IEC 61000-4-2 certification; lower capacitance benefits >500MHz links but reduces clamping margin | Select for ultra-high-speed SerDes lanes where sub-4pF is mandatory and IEC testing not required |
Compared with SP3204-01UTG and ESD401-4BF, MAX3204EEWT+T uniquely balances IEC-certified ±15kV air-gap immunity, 5pF capacitance, and 1.05mm × 1.57mm WLP size - making it optimal for space-constrained Ethernet/FireWire endpoints requiring full standard compliance.

FAQ
What is the exact package type and dimensions of MAX3204EEWT+T?
MAX3204EEWT+T uses a 6-bump Wafer-Level Package (WLP) with dimensions of 1.05mm × 1.57mm and a 0.4mm bump pitch. The top mark is "+AL", and the package is lead(Pb)-free/RoHS-compliant. It contains four I/O bumps (A1, A2, B2, B3), one VCC bump (A3), and one GND bump (B1), with no exposed pad or NC terminals.
Does MAX3204EEWT+T require an external bypass capacitor, and if so, what value and placement is recommended?
Yes, MAX3204EEWT+T requires a 0.1µF ceramic capacitor between VCC and GND. This capacitor must be placed as close as possible to the VCC and GND bumps - ideally within 2mm trace length - to minimize loop inductance and ensure effective absorption of ESD energy during IEC 61000-4-2 contact discharge events.
What is the maximum clamping voltage of MAX3204EEWT+T under ±15kV IEC 61000-4-2 air-gap discharge?
Under ±15kV IEC 61000-4-2 air-gap discharge conditions (45A peak current), MAX3204EEWT+T exhibits a channel clamp voltage of +VCC + 100V for positive transients and –100V for negative transients. This value assumes ideal layout; actual clamping rises with PCB trace inductance - hence strict adherence to layout guidelines is essential.
Can MAX3204EEWT+T be used to protect USB 2.0 high-speed (480Mbps) differential pairs?
Yes, MAX3204EEWT+T is suitable for USB 2.0 high-speed protection. Its 5pF per-channel capacitance introduces negligible insertion loss at 240MHz fundamental frequency, and its ±15kV HBM/±8kV IEC ratings exceed USB-IF ESD requirements. Use one MAX3204EEWT+T per port to protect both D+ and D– lines plus two auxiliary signals if needed.
How does the leakage current specification of MAX3204EEWT+T impact high-impedance receiver circuits?
MAX3204EEWT+T specifies ≤1nA channel leakage current over 0°C to +50°C, which ensures minimal DC loading on high-impedance inputs such as those found in Ethernet PHY receivers or FireWire transceivers. This prevents input bias shift, false detection, or degraded common-mode rejection - critical for maintaining signal fidelity in precision analog front-ends.
