Product details
Overview
MAX13204EELT+ from Maxim Integrated is a quad-channel ±30kV ESD protection diode array in a 6-pin µDFN (2mm × 2mm) package, designed for high-speed data lines including Ethernet and FireWire® interfaces. It delivers 6pF channel input capacitance, ±15kV HBM and ±30kV IEC 61000-4-2 air-gap ESD protection, and operates from +0.9V to +16V supply voltage across -40°C to +125°C.
For engineers reviewing the MAX13204EELT+ datasheet, MAX13204EELT+ pinout, MAX13204EELT+ application, or MAX13204EELT+ equivalent, key selection criteria include low clamping voltage under ±30kV air-gap discharge, leakage current ≤1nA at +25°C, compatibility with 5V/12V supply rails, and suitability for space-constrained automotive-grade Ethernet/FireWire port protection.
Technical Context
The MAX13204EELT+ integrates four bidirectional ESD protection diodes per channel, each steering transient current to VCC or GND via internal diode clamping architecture. Its design targets high-speed I/O where signal integrity depends on sub-6pF capacitance and fast response to ±30kV IEC 61000-4-2 air-gap pulses.
Clamp voltage is defined by forward diode drop plus supply rail offset: VC = VCC + VF for positive transients and VC = –VF for negative transients. The device requires a 0.1µF ceramic bypass capacitor between VCC and GND, placed adjacent to pins 1 (VCC) and 6 (GND), to absorb charge during contact discharge events up to ±14kV.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Protection Level | ±30kV per IEC 61000-4-2 Air-Gap Discharge - enables robust front-end protection for unshielded connectors exposed to field handling. |
| Channel Input Capacitance | 6pF at 1MHz, VCC/2 bias - preserves signal integrity on USB 2.0, Ethernet, and FireWire® data lines up to 480Mbps. |
| Supply Voltage Range | +0.9V to +16V - supports direct integration with 3.3V, 5V, and 12V I/O rails without level-shifting circuitry. |
| Leakage Current | ≤1nA at +25°C - minimizes standby power loss and avoids interference with high-impedance sensor or analog signal paths. |
| Operating Temperature | -40°C to +125°C - qualified for under-hood automotive, industrial control, and extended-temperature embedded systems. |
| Clamp Voltage | VCC + 120V (positive), -120V (negative) at 90A peak - limits transient overvoltage seen by downstream PHY or controller ICs. |
Pinout & Package
MAX13204EELT+ uses a 6-pin µDFN package (2mm × 2mm × 0.8mm, pkg code L622-1), with exposed pad for thermal enhancement and mechanical stability. Pin 1 is VCC; pin 6 is GND; pins 2–5 are protected I/O channels (I/O1–I/O4).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Power-supply input; must be bypassed to GND with 0.1µF ceramic capacitor placed within 2mm of pin for effective ESD energy absorption. |
| 2 | I/O1 | First ESD-protected bidirectional data line; clamps transients to VCC or GND using integrated diode pair. |
| 3 | I/O2 | Second ESD-protected bidirectional data line; electrically isolated from other I/O pins except through shared VCC/GND rails. |
| 4 | I/O3 | Third ESD-protected bidirectional data line; identical electrical characteristics and layout requirements as I/O1–I/O2. |
| 5 | I/O4 | Fourth ESD-protected bidirectional data line; supports full-duplex or differential signaling when paired with adjacent channels. |
| 6 | GND | Ground reference for all clamp paths; shortest possible PCB trace to system ground plane required to minimize inductive voltage overshoot. |
Key Features
| Feature | Design Value |
|---|---|
| Quad-channel ESD protection | Four independent bidirectional diode clamps in one 2mm × 2mm footprint - reduces component count and board area vs. discrete TVS arrays. |
| Low 6pF input capacitance | Preserves rise/fall time and eye diagram integrity on 480Mbps USB 2.0 and 100Mbps Ethernet signals - no equalization or retiming needed. |
| ±30kV IEC 61000-4-2 air-gap rating | Validated protection against real-world electrostatic discharge from human proximity without physical contact - critical for handheld and docking interfaces. |
| Automotive temperature range | Full functionality from -40°C to +125°C - eliminates derating or thermal monitoring in engine-control, infotainment, and ADAS subsystems. |
| 1nA max leakage at +25°C | Prevents DC loading of high-impedance receiver inputs - essential for precision analog sensors or battery-powered portable devices. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1004-04UTG | 4-channel, 5.5pF typical capacitance, ±30kV IEC 61000-4-2, but rated only to +85°C operating temperature. | Limited to commercial/industrial environments; not qualified for automotive under-hood use. | Select SP1004-04UTG only if ambient temperature stays below +85°C and lower capacitance is prioritized over temperature range. |
| ESD7L5.0ST5G | Single-channel, 5.5pF, ±30kV IEC 61000-4-2, SOT-553 package; requires four separate placements for quad protection. | Increases PCB area and assembly cost; lacks integrated VCC/GND rail coordination for multi-line transients. | Choose ESD7L5.0ST5G only when board layout constraints prevent µDFN placement or when channel-level replacement is required. |
Compared with SP1004-04UTG and ESD7L5.0ST5G, MAX13204EELT+ uniquely combines automotive-grade temperature operation (-40°C to +125°C), quad-channel integration in a single 2mm × 2mm µDFN, and guaranteed 6pF capacitance - making it optimal for space-constrained, high-reliability Ethernet and FireWire® designs where thermal and layout margins are tight.

FAQ
What is the maximum clamping voltage of MAX13204EELT+ under ±30kV IEC 61000-4-2 air-gap discharge?
The MAX13204EELT+ exhibits a maximum clamping voltage of VCC + 120V for positive transients and -120V for negative transients when subjected to ±30kV IEC 61000-4-2 air-gap discharge at 90A peak current. This value assumes ideal layout with minimal parasitic inductance; actual clamping at the protected IC may rise due to PCB trace inductance, so VCC bypassing and short GND paths are mandatory to achieve the specified performance. The MAX13204EELT+ datasheet confirms this limit under TA = +25°C conditions.
Does MAX13204EELT+ require an external VCC supply to function, and what happens if VCC is unpowered?
Yes, MAX13204EELT+ requires a valid VCC supply (0.9V to 16V) to enable its active clamping path for positive ESD transients. Without VCC, the device still provides negative transient protection via GND-referenced diodes, but positive transients will clamp only to ~-0.9V (forward diode drop), potentially exceeding downstream IC absolute maximum ratings. The MAX13204EELT+ datasheet specifies that VCC must be present and bypassed for full ±30kV protection capability - operation with floating or disconnected VCC is not characterized.
Can MAX13204EELT+ be used to protect differential high-speed signals like USB 2.0 D+ and D– simultaneously?
Yes, MAX13204EELT+ supports simultaneous protection of differential pairs such as USB 2.0 D+ and D–: pins 2 and 3 serve as I/O1 and I/O2, respectively, and each operates independently with matched 6pF capacitance and identical clamping behavior. This ensures common-mode noise rejection and maintains differential signal integrity without skew or imbalance. The MAX13204EELT+ datasheet explicitly lists USB 2.0 among its target applications and confirms symmetrical electrical parameters across all four channels.
What is the recommended PCB layout practice for MAX13204EELT+ to ensure ±30kV ESD performance?
To guarantee ±30kV IEC 61000-4-2 performance, MAX13204EELT+ requires: (1) 0.1µF X7R ceramic capacitor placed ≤2mm from pins 1 (VCC) and 6 (GND); (2) I/O traces from connector to pins 2–5 kept ≤5mm long and routed over solid ground plane; (3) GND pin 6 connected directly to system ground plane with ≥2 vias; (4) no routing of sensitive signals near MAX13204EELT+ edges. These practices minimize parasitic inductance, which otherwise adds hundreds of volts to clamp voltage - the MAX13204EELT+ datasheet cites 10nH inductance causing +450V overshoot at 45A/ns di/dt.
Is MAX13204EELT+ compliant with RoHS and lead-free soldering standards?
Yes, MAX13204EELT+ carries the '+' suffix indicating a lead-free, RoHS-compliant package. It is qualified for reflow soldering per JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1), with peak reflow temperature up to +260°C. The device uses matte tin plating and meets IPC/JEDEC J-STD-006 requirements for lead-free terminations. This information is confirmed in Maxim's official ordering table and package documentation for MAX13204EELT+.
