Product details
Overview
The MAX3204EEBT+T from Maxim Integrated is a quad-channel ±15kV ESD protection diode array in a 6-pin TDFN-EP package, designed to safeguard high-speed data lines including Ethernet and FireWire® interfaces. It delivers 5pF per channel input capacitance, ±15kV HBM / ±8kV IEC 61000-4-2 contact / ±15kV air-gap ESD immunity, and operates from +0.9V to +5.5V supply voltage.
For engineers reviewing the MAX3204EEBT+T datasheet, MAX3204EEBT+T pinout, MAX3204EEBT+T application, or MAX3204EEBT+T equivalent, key selection criteria include channel count (4), low 5pF capacitance for USB 2.0/Ethernet signal integrity, clamp voltage performance under IEC 61000-4-2 waveforms, and compatibility with 0.1µF VCC-to-GND bypassing in compact layouts.
Technical Context
This device implements bidirectional steering diode architecture per channel: during positive transients, current is clamped to VCC via forward-biased diodes; during negative transients, current is steered to GND. Each channel features matched diode pairs with guaranteed ≤0.95V forward voltage at 10mA.
Clamp voltage is defined by VC = VCC + VF for positive ESD events and VC = –VF for negative events-subject to parasitic inductance effects. The 6-pin TDFN-EP package includes an exposed pad (EP) that must be connected to GND to ensure thermal and ESD return path integrity.
Key Specifications

Pinout & Package
The MAX3204EEBT+T is housed in a 6-pin TDFN-EP package (3mm × 3mm, 0.75mm height) with exposed pad. Pin 1 is marked by a dot; EP must be soldered to GND for optimal thermal dissipation and ESD current return path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | I/O1 | ESD-protected data line input/output - connects directly to connector or high-speed interface trace |
| 2 | I/O2 | ESD-protected data line input/output - independent channel with identical diode characteristics as Pin 1 |
| 3 | GND | Ground reference for ESD current shunting - low-inductance connection required for effective clamping |
| 4 | I/O3 | ESD-protected data line input/output - third independent channel; shares same VCC/GND rails |
| 5 | VCC | Power-supply input - must be bypassed with 0.1µF ceramic capacitor placed within 2mm of this pin |
| 6 | I/O4 | ESD-protected data line input/output - fourth independent channel; completes quad-channel protection set |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP3012-04UTG | 4-channel, 0.3pF typical capacitance, ±12kV IEC contact, SOT-23-6 package | Lower capacitance suits >1Gbps interfaces but reduced ESD margin; smaller footprint lacks exposed pad | Select when ultra-low capacitance is critical and IEC ±8kV suffices; verify layout for higher di/dt sensitivity |
| TPD4E001DQAR | 4-channel, 0.75pF typical capacitance, ±15kV IEC contact, X2SON-8 package | Higher ESD rating consistency across temperature; integrated RC filter option available | Prefer for automotive-grade designs requiring AEC-Q200 qualification and tighter parametric stability over –40°C to +125°C |
Compared with SP3012-04UTG and TPD4E001DQAR, the MAX3204EEBT+T offers balanced 5pF/±15kV performance in a thermally enhanced TDFN-EP package-ideal for industrial Ethernet and FireWire® where layout-controlled inductance and thermal management are prioritized over sub-1pF capacitance.

FAQ
What is the maximum operating temperature range for the MAX3204EEBT+T?
The MAX3204EEBT+T is specified to operate reliably from –40°C to +85°C ambient temperature. This range covers standard industrial and commercial environments. Thermal derating begins above +70°C, with power dissipation reduced by 24.4mW/°C due to its 6-pin TDFN-EP package's θJA of 42°C/W. Full ESD performance is maintained across the entire range.
Does the MAX3204EEBT+T require external components for basic ESD protection functionality?
Yes-the MAX3204EEBT+T requires a 0.1µF ceramic bypass capacitor between VCC and GND, placed within 2mm of the VCC pin. This capacitor absorbs charge from IEC 61000-4-2 contact discharge events and stabilizes the clamping reference. No series resistors or additional diodes are needed for standard operation, but PCB layout must minimize trace inductance on I/O and ground paths.
How does the MAX3204EEBT+T achieve ±15kV ESD protection with only 5pF capacitance?
The MAX3204EEBT+T achieves this through optimized BiCMOS process diode geometry and low-parasitic WLP/TDFN packaging. Its 5pF input capacitance results from minimized junction area and controlled oxide thickness-enabling fast response without excessive capacitive loading. The ±15kV rating is validated under IEC 61000-4-2 test conditions using the specified layout and 0.1µF bypass cap.
Can the MAX3204EEBT+T be used to protect USB 2.0 D+ and D– lines?
Yes-the MAX3204EEBT+T is explicitly recommended for USB 2.0 applications in its datasheet. Its 5pF per-channel capacitance preserves signal integrity at 480Mbps, and its quad-channel configuration allows simultaneous protection of D+, D–, ID, and VBUS. For full-speed USB, ensure VBUS clamping remains within +5.5V and use proper 0.1µF bypassing on VCC.
What is the function of the exposed pad (EP) on the MAX3204EEBT+T package?
The exposed pad (EP) on the MAX3204EEBT+T must be soldered to a GND plane. It serves two critical functions: (1) provides a low-inductance return path for ESD current during transient events, improving clamp effectiveness; and (2) enhances thermal conduction from the die to the PCB, lowering junction temperature by up to 30°C under sustained stress-key for reliability in compact designs.
