Product details
Overview
The MAX13204EALT+T from Maxim Integrated is a quad-channel, low-capacitance ESD protection diode array in a 6-pin µDFN (2mm × 2mm) package, rated for ±30kV air-gap and ±15kV HBM ESD immunity per IEC 61000-4-2 and JEDEC JS-001. It features 6pF channel input capacitance, 1nA max leakage current at +125°C, and operates from +0.9V to +16V supply voltage - designed specifically for high-speed Ethernet and FireWire® data-line protection.
For engineers reviewing the MAX13204EALT+T datasheet, MAX13204EALT+T pinout, MAX13204EALT+T application, or MAX13204EALT+T equivalent, key selection criteria include channel count (4), ultra-low capacitance (6pF), automotive-grade temperature range (–40°C to +125°C), µDFN package footprint compatibility, and IEC 61000-4-2 Level 4 compliance for robust system-level ESD resilience.
Technical Context
The MAX13204EALT+T implements a bidirectional diode-steering architecture that clamps positive transients to VCC + VF (≤ VCC + 0.95V) and negative transients to –VF (≥ –0.95V) under 10mA forward bias, with peak clamp voltages of +120V/–120V during ±30kV air-gap discharge (IEC 61000-4-2, 90A pulse). Its BiCMOS process enables stable leakage performance across –40°C to +125°C.
Each of its four protected I/O channels shares a common VCC and GND terminal, requiring external 0.1µF ceramic bypassing between VCC and GND to absorb ESD charge during contact discharge events. Layout-critical parasitic inductance directly impacts effective clamp voltage - a 10nH trace adds ~450V overshoot during 45A/1ns ESD edge rates.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±30kV air-gap discharge (IEC 61000-4-2), ±15kV HBM - meets Level 4 system ESD immunity without secondary protection. |
| Channel Count | 4 independent ESD-protected I/O lines - matches standard Ethernet (10/100BASE-TX) and FireWire® 400 signal pair count. |
| Input Capacitance | 6pF per channel at 5V bias and 1MHz - preserves signal integrity on >480Mbps USB 2.0 and 100Mbps Ethernet links. |
| Leakage Current | ≤1nA at +25°C, ≤1µA at +125°C - avoids DC loading on high-impedance video or sensor interfaces. |

| Operating Temp | –40°C to +125°C - qualified for under-hood automotive, industrial control, and extended-temperature embedded applications. |
| Package | 6-pin µDFN (2mm × 2mm × 0.8mm), L622-1 code - surface-mount compatible with fine-pitch PCB assembly and thermal pad grounding. |
Pinout & Package
MAX13204EALT+T uses a 6-pin µDFN package (2mm × 2mm, 0.8mm height) with exposed thermal pad (GND-connected). Pin 1 is marked by top-side laser marking "AAO" and located at the bottom-left corner when the index area is oriented toward the viewer.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Positive supply rail - must be bypassed to GND with 0.1µF ceramic capacitor placed within 2mm of pin for ESD energy absorption. |
| 2 | I/O1 | ESD-protected data line - connects to first high-speed interface signal (e.g., Ethernet TX+ or FireWire D+). |
| 3 | I/O2 | ESD-protected data line - pairs with I/O1 for differential signaling; requires matched trace length and impedance control. |
| 4 | I/O3 | ESD-protected data line - supports second differential pair (e.g., Ethernet RX+ or FireWire D–). |
| 5 | I/O4 | ESD-protected data line - completes quad-channel coverage; routed separately to avoid coupling with VCC/GND paths. |
| 6 | GND | Ground reference and ESD return path - connected to exposed thermal pad; must tie to solid ground plane with ≥4 vias. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E05U06DQAR | 4-channel, 5.5V max VCC, 0.5pF lower capacitance (5.5pF), ±12kV contact discharge rating. | Better suited for 3.3V-only USB 2.0 or MIPI D-PHY; lacks automotive temp range and ±30kV air-gap rating. | Select when ultra-low capacitance is critical and system operates strictly at 3.3V with lower ESD threat profile. |
| SP4044-04UTG | 4-channel, 3.3V fixed VCC, 10pF capacitance, ±15kV HBM only - no IEC 61000-4-2 certification. | Targeted at cost-sensitive consumer electronics; not qualified for automotive or industrial environments. | Choose for non-automotive applications where budget constraints outweigh need for IEC 61000-4-2 Level 4 validation. |
Compared with TPD4E05U06DQAR and SP4044-04UTG, the MAX13204EALT+T uniquely delivers ±30kV air-gap immunity, 0.9V–16V supply flexibility, and full –40°C to +125°C qualification - making it the only option among the three suitable for automotive Ethernet and high-voltage industrial data links.

FAQ
What is the maximum clamping voltage of the MAX13204EALT+T during a ±30kV IEC 61000-4-2 air-gap discharge event?
The MAX13204EALT+T exhibits a peak channel clamp voltage of +120V for positive transients and –120V for negative transients under ±30kV air-gap discharge (IEC 61000-4-2, 90A pulse). This value assumes ideal layout with minimized parasitic inductance; actual board-level clamp voltage increases by L × di/dt, where even 10nH adds ~450V overshoot during fast-rising ESD edges.
Does the MAX13204EALT+T require an external VCC bypass capacitor, and if so, what value and placement is recommended?
Yes, the MAX13204EALT+T requires a 0.1µF ceramic capacitor between VCC and GND. This capacitor must be placed within 2mm of the VCC and GND pins to effectively absorb ESD charge during contact discharge events. A low-ESR X7R or C0G dielectric is mandatory - placement farther than 5mm from the pins significantly degrades ESD suppression performance.
Can the MAX13204EALT+T be used to protect 1000BASE-T (Gigabit Ethernet) interfaces?
No, the MAX13204EALT+T is not recommended for 1000BASE-T. Its 6pF per-channel capacitance introduces excessive insertion loss above 125MHz, degrading the 100MHz–400MHz spectral content required for Gigabit Ethernet. It is validated for 10/100BASE-TX (≤31.25MHz fundamental) and FireWire® 400 (up to 400Mbps baseband).
What is the leakage current specification of the MAX13204EALT+T at +125°C, and how does it impact high-impedance analog circuits?
The MAX13204EALT+T specifies ≤1µA maximum channel leakage current at +125°C. At room temperature, leakage is ≤1nA. In high-impedance analog circuits (e.g., sensor front-ends or precision ADC inputs), this leakage can introduce offset errors or drift - designers should verify total input bias current budgets and consider guard traces if leakage-induced error exceeds system accuracy requirements.
Is the MAX13204EALT+T pin-compatible with other members of the MAX1320x family, such as the MAX13202EALT+ or MAX13206EALA+?
No, the MAX13204EALT+T is not pin-compatible with MAX13202EALT+ or MAX13206EALA+. While all use µDFN packages, MAX13202EALT+ is 6-pin (1mm × 1.5mm), MAX13204EALT+T is 6-pin (2mm × 2mm), and MAX13206EALA+ is 8-pin (2mm × 2mm). Pin functions differ: MAX13204EALT+T assigns pins 2–5 to I/O1–I/O4, whereas MAX13202EALT+ uses pins 3–4 for I/O1–I/O2 and leaves pins 2 and 5 unconnected.
