Product details
Overview
MAX3205EABL+T from Maxim Integrated is a six-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 high-speed differential or single-ended signal lines in cell phone connectors and SVGA video interfaces.
For engineers reviewing the MAX3205EABL+T datasheet, MAX3205EABL+T pinout, MAX3205EABL+T application, or MAX3205EABL+T equivalent, this device delivers precise channel-to-channel capacitance matching (±0.05pF), automotive-grade operation (−40°C to +125°C), and optimized WLP layout for controlled-impedance routing-critical for HDMI/DVI/USB 2.0 signal integrity and ESD robustness.
Technical Context
The MAX3205EABL+T implements a dual-diode per channel architecture that steers ESD current to VCC or GND, with an integrated TVS clamping VCC during transients to limit voltage excursion. It operates with VCC = 0.9V to 5.5V and draws only 1–100nA supply current.
Each of its six protected I/O channels exhibits 2.5–3.0pF input capacitance at VCC = 3.3V, with leakage current ≤ ±0.1μA across temperature. Clamp voltage is specified as VCC + 25V (HBM), VCC + 60V (IEC contact), and VCC + 100V (IEC air-gap) for positive transients, and symmetric negative values.
Key Specifications

Use Value: Eliminates field failures due to electrostatic discharge during card insertion/removal without requiring board-level redesign. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD6E05U06RSLR | 6-channel, 0.5pF lower capacitance (1.5pF typ), but rated only to ±12kV HBM and ±8kV IEC contact; no integrated VCC TVS. | Preferred for ultra-high-speed (>1Gbps) SerDes where sub-2pF is mandatory; unsuitable where VCC rail clamping is required. | Select when lowest possible capacitance is prioritized over full IEC air-gap rating and VCC stabilization. |
| SP3205-01UTG | 6-channel, same ±15kV HBM/IEC ratings, 2.5pF capacitance, but uses SOT-23-6L package - larger footprint and higher inductance than WLP. | Used where reflow compatibility with legacy SMT processes is required; not suitable for space-constrained mobile PCBs. | Choose when WLP assembly infrastructure is unavailable or thermal constraints favor larger package thermal mass. |
Compared with TPD6E05U06RSLR and SP3205-01UTG, the MAX3205EABL+T uniquely combines full ±15kV air-gap immunity, integrated VCC TVS clamping, and 1.5mm × 1.5mm WLP packaging-enabling compact, robust, and rail-stable ESD protection in next-generation portable displays and interface modules.

FAQ
What is the exact package type and footprint of the MAX3205EABL+T?
The MAX3205EABL+T uses a 9-bump wafer-level package (WLP) with dimensions of 1.5mm × 1.5mm × 0.5mm and a 0.4mm bump pitch. Its land pattern follows Maxim's W91B1+5 outline (package drawing 21-0067), with solder bumps located at positions A1 (GND), A2–A3/B1–B3/C1–C2 (I/O₁–I/O₆), and C3 (VCC); bump B2 is omitted. This WLP enables direct chip-scale mounting with minimal parasitic inductance.
Does the MAX3205EABL+T require an external capacitor on VCC, and if so, what value and placement is recommended?
Yes, the MAX3205EABL+T requires a 0.1μF low-ESR ceramic capacitor placed between VCC and GND, mounted as close as possible to the C3 bump. This capacitor stabilizes the VCC rail during ESD events, ensuring the integrated TVS clamp operates within its specified voltage window. Without it, VCC can overshoot significantly, reducing protection effectiveness and potentially damaging downstream circuitry powered from the same rail.
How does the MAX3205EABL+T achieve ±15kV air-gap ESD protection while maintaining only 2.5–3.0pF input capacitance?
The MAX3205EABL+T achieves this balance through BiCMOS process optimization and precision diode geometry design. Its low 2.5–3.0pF capacitance results from minimized junction area and controlled doping profiles, while the ±15kV air-gap rating is validated via IEC 61000-4-2 testing at 45A peak current. The integrated TVS further ensures clamping remains predictable even under high di/dt conditions, decoupling capacitance requirements from voltage-withstand capability.
Can the MAX3205EABL+T be used to protect differential pairs such as USB 2.0 D+/D− or HDMI TMDS lines?
Yes, the MAX3205EABL+T is explicitly designed for high-speed differential signal protection. Each of its six I/O channels operates independently and bidirectionally, allowing pairing of adjacent channels (e.g., A2/A3 for D+, B1/B3 for D−) on controlled-impedance traces. Its tight ±0.05pF channel-to-channel capacitance match prevents skew, and its 2.5–3.0pF loading preserves USB 2.0 eye diagrams and HDMI signal integrity up to 1.65Gbps.
Is the MAX3205EABL+T compliant with automotive AEC-Q200 stress testing requirements?
No-the MAX3205EABL+T is specified for the −40°C to +125°C automotive operating temperature range and meets IEC 61000-4-2 Level 4, but it is not AEC-Q200 qualified. For AEC-Q200-compliant alternatives, designers should consider the MAX3205HEWL+T (Q200-qualified variant) or consult Maxim's automotive-grade ESD portfolio. The MAX3205EABL+T remains suitable for non-safety-critical automotive infotainment and display applications where full qualification is not mandated.
