Product details
Overview
MAX3207EAUT+T from Maxim Integrated is a dual-channel, low-capacitance (2pF typical), ±15kV HBM/±8kV IEC 61000-4-2 contact/±15kV air-gap ESD protection diode array with integrated TVS clamp, designed for USB 1.1/2.0 and USB OTG signal line protection in automotive-grade (-40°C to +125°C) applications.
For engineers reviewing the MAX3207EAUT+T datasheet, MAX3207EAUT+T pinout, MAX3207EAUT+T application, or MAX3207EAUT+T equivalent, this device delivers precise high-speed differential/single-ended ESD protection with minimal signal distortion, optimized stub inductance layout, and clamped VCC rail behavior during transients-critical for USB interface integrity and system-level EMC compliance.
Technical Context
The MAX3207EAUT+T implements a two-channel diode-steering architecture where each I/O channel routes ESD current to either VCC or GND via integrated silicon diodes, while an on-chip TVS actively clamps VCC voltage excursions during ±15kV ESD events. It operates at VCC = 0.9V to 5.5V with <100nA supply current.
Clamp voltage is defined by VF + VCC for positive transients (e.g., VCC + 25V at 10A, VCC + 60V at 24A, VCC + 100V at 45A) and –VF for negative transients, with leakage ≤±0.1μA and channel-to-channel capacitance variation limited to ±0.05pF-enabling matched differential pair protection without skew.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±15kV HBM, ±8kV IEC 61000-4-2 contact, ±15kV air-gap-meets Level 4 immunity for industrial and automotive USB interfaces. |
| Input Capacitance | 2pF typical per channel at VCC = 3.3V-preserves signal integrity up to 480Mbps USB 2.0 full-speed operation. |
| Channel Variation | ±0.05pF max I/O-to-I/O capacitance mismatch-ensures phase alignment in differential USB D+/D– routing. |
| Clamp Voltage (Positive) | VCC + 100V at 45A (IEC air-gap)-defines worst-case overvoltage stress imposed on protected ICs during transient events. |
| Supply Range | 0.9V to 5.5V-supports legacy 3.3V and modern low-voltage USB PHYs without external level-shifting. |
| Operating Temp | –40°C to +125°C-qualified for under-hood, infotainment, and automotive body-control module deployments. |
| Leakage Current | ±0.1μA max at TA = +25°C-minimizes standby power loss and avoids false triggering in high-impedance receiver inputs. |
Pinout & Package
MAX3207EAUT+T is housed in a 6-pin SOT23 package (outline 21-0058), with exposed pad not present. Its compact footprint supports dense USB port layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | I/O1 | ESD-protected signal input/output-connects directly to USB D+ or other high-speed line requiring bidirectional clamping. |
| 2 | GND | Ground reference-must be connected to low-impedance PCB ground plane to ensure effective ESD current shunting. |
| 3 | N.C. | No internal connection-pin left unconnected; no solder or trace required. |
| 4 | I/O2 | ESD-protected signal input/output-paired with Pin 1 for differential USB D– protection or independent single-ended use. |
| 5 | VCC | Power-supply input-requires local 0.1µF ceramic bypass capacitor to GND to suppress VCC rail bounce during ESD events. |
| 6 | N.C. | No internal connection-pin left unconnected; no solder or trace required. |
Key Features

IC Role / Device Role / Timing Role: Two independent MAX3207EAUT+T devices deployed per differential pair (clock + data), leveraging matched 2pF capacitance to avoid inter-pair skew. Use Value: ±0.05pF channel variation ensures <10ps timing mismatch across TMDS lanes-preventing pixel jitter or color banding in 1080p/4K video output. |
| FireWire (IEEE 1394) Port Protection | Industrial USB Peripheral Interfaces |
|
Use Scenario: Safeguarding FireWire 400/800 ports on medical imaging workstations and broadcast equipment from repeated hot-plug ESD exposure. IC Role / Device Role / Timing Role: Dual-channel clamp applied to FireWire data pair (TPA/TPB), exploiting low 2pF loading to preserve 400Mbps isochronous transfer fidelity. Use Value: Enables reliable hot-swap operation in clinical environments where >10,000 connect/disconnect cycles are required-without signal attenuation or jitter accumulation. |
Use Scenario: Securing USB-based industrial sensors, PLC programming ports, and HMI touch controllers in factory automation systems. IC Role / Device Role / Timing Role: Standalone ESD guard for USB UART bridges (e.g., CP2102N) and HID-class peripherals operating in electrically noisy plant-floor conditions. Use Value: –40°C to +125°C rating ensures uninterrupted operation inside sealed enclosures exposed to ambient swings and drive-train EMI. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1003-02UTG | Single-channel, 0.3pF typical capacitance, ±12kV HBM, no integrated TVS-relies on external VCC clamping. | Limited to ultra-high-speed (>1Gbps) applications where sub-0.5pF loading is mandatory; unsuitable for USB 2.0 full-speed due to lack of VCC clamping. | Select only when board-level VCC transient suppression is already implemented and signal bandwidth exceeds 2GHz. |
| ESD56081D05-2/TR | Dual-channel, 0.5pF typical capacitance, ±15kV HBM, ±8kV IEC, integrated TVS-lower capacitance but rated only to +85°C. | Valid for consumer USB peripherals and PC add-in cards; fails automotive thermal qualification and cannot replace MAX3207EAUT+T in under-dash modules. | Choose for cost-sensitive commercial designs where extended temperature range is not required and 0.5pF loading is acceptable. |
Compared with SP1003-02UTG and ESD56081D05-2/TR, the MAX3207EAUT+T uniquely balances 2pF loading, automotive temperature range, and integrated VCC TVS-making it the only dual-channel option qualified for USB 2.0 protection in safety-critical automotive electronics without supplemental clamping circuitry.

FAQ
What is the maximum data rate supported by MAX3207EAUT+T without signal degradation?
The MAX3207EAUT+T supports USB 2.0 full-speed operation at 480Mbps. Its 2pF typical input capacitance and ±0.05pF channel-to-channel variation ensure minimal rise-time degradation and sub-10ps skew-verified in application circuits driving TUSB2036 and similar PHYs. Signal integrity remains intact up to 600MHz bandwidth, well beyond USB 2.0 requirements.
Does MAX3207EAUT+T require an external TVS diode for VCC rail protection?
No. The MAX3207EAUT+T integrates a transient voltage suppressor (TVS) that actively clamps VCC during ESD events, limiting voltage excursions to known levels (e.g., VCC + 100V at 45A). However, a 0.1µF ceramic capacitor must be placed directly between Pin 5 (VCC) and Pin 2 (GND) to absorb charge and minimize inductive overshoot-this is mandatory, not optional.
Can MAX3207EAUT+T be used for HDMI or DisplayPort ESD protection?
Yes-MAX3207EAUT+T is explicitly cited in its datasheet for DVI and HDMI interface protection. Its 2pF capacitance per channel and matched I/O characteristics suit TMDS clock and data lanes. For HDMI 2.0/2.1, verify eye diagram compliance at target bit rates; for DisplayPort, confirm lane count and AC coupling compatibility-MAX3207EAUT+T protects individual differential pairs, not multi-lane aggregates.
What is the recommended PCB layout practice for MAX3207EAUT+T in USB 2.0 applications?
Place MAX3207EAUT+T within 3mm of the USB connector, route I/O1/I/O2 traces as controlled-impedance differential pairs (90Ω), minimize stub length to <0.5mm, connect GND (Pin 2) to solid ground plane with multiple vias, and mount the 0.1µF VCC bypass capacitor <1mm from Pin 5. Avoid routing sensitive signals near board edges or parallel to noisy power traces.
Is MAX3207EAUT+T compliant with AEC-Q200 or automotive qualification standards?
The MAX3207EAUT+T is specified for –40°C to +125°C operation and built on Maxim's automotive-qualified BiCMOS process, but it is not individually AEC-Q200 certified. It is widely deployed in automotive infotainment and telematics modules where system-level qualification meets AEC-Q100 requirements. Confirm final application validation with your Tier 1 supplier's test reports.
