Product details
Overview
The MAX3202EEWS+T from Maxim Integrated is a two-channel, low-capacitance ESD protection diode array designed for USB and USB 2.0 data lines. It delivers ±15kV HBM and ±15kV IEC 61000-4-2 air-gap ESD protection, features 5pF per-channel input capacitance, 1nA max leakage current, and operates from +0.9V to +5.5V supply voltage - enabling robust high-speed interface protection without signal integrity degradation.
For engineers reviewing the MAX3202EEWS+T datasheet, MAX3202EEWS+T pinout, MAX3202EEWS+T application, or MAX3202EEWS+T equivalent, key selection criteria include channel count (2), ultra-low capacitance (5pF), ±15kV ESD rating per IEC 61000-4-2, WLP package footprint (1.05mm × 1.05mm), and compatibility with USB 2.0 signal integrity requirements.
Technical Context
The MAX3202EEWS+T implements a dual-diode steering architecture per channel, clamping positive transients to VCC + VF and negative transients to –VF during ESD events. Its BiCMOS process enables low leakage (≤1nA) and stable clamp behavior across –40°C to +85°C.
Clamp voltage is specified at ±25V (HBM), ±60V (IEC contact), and ±100V (IEC air-gap) under defined test currents (10A/24A/45A). The device requires a 0.1µF ceramic bypass capacitor between VCC and GND to maintain effective clamping under fast-rising ESD pulses.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2EUSB30DRYR | 3-channel, 0.7pF typical capacitance, ±8kV IEC contact, 1.5mm × 1.0mm X2SON | Optimized for USB 3.0 SuperSpeed (5Gbps); not rated for ±15kV air-gap discharge | Select when lower capacitance is critical and USB 3.0 support is required; verify IEC 61000-4-2 Level 4 compliance separately |
| SP1001-02UTG | 2-channel, 0.6pF typical capacitance, ±12kV air-gap, SOT-563 package (1.6mm × 1.6mm) | Larger footprint; lower ESD rating; higher thermal resistance (θJA = 210°C/W) | Choose only if WLP assembly capability is unavailable; expect reduced layout flexibility and higher clamp voltage under fast transients |
Compared with TPD2EUSB30DRYR and SP1001-02UTG, the MAX3202EEWS+T uniquely balances ±15kV air-gap compliance, USB 2.0-optimized 5pF capacitance, and minimal 1.05mm × 1.05mm WLP footprint - making it the preferred choice for space-constrained, Level 4-certified USB 2.0 designs where signal fidelity and robustness are co-prioritized.

FAQ
What is the primary function of the MAX3202EEWS+T?
The MAX3202EEWS+T is a two-channel ESD protection diode array designed to safeguard USB 2.0 data lines (D+ and D–) from electrostatic discharge events. It steers ESD current to VCC or GND using internal diode clamps, with verified ±15kV Human Body Model and ±15kV IEC 61000-4-2 air-gap protection. Its 5pF per-channel capacitance ensures minimal impact on USB 2.0 signal integrity, and the MAX3202EEWS+T is packaged in a 1.05mm × 1.05mm wafer-level package for compact placement near connectors.
Does the MAX3202EEWS+T require an external bypass capacitor?
Yes, the MAX3202EEWS+T requires a 0.1µF ceramic bypass capacitor connected between its VCC and GND terminals. This capacitor absorbs charge during ESD events-especially critical for IEC 61000-4-2 contact discharge-and stabilizes the clamp voltage by minimizing supply rail impedance. Placement must be within 2mm of the MAX3202EEWS+T VCC bump; failure to include this capacitor degrades ESD performance and may cause excessive voltage overshoot on protected lines.
What is the operating voltage range of the MAX3202EEWS+T?
The MAX3202EEWS+T operates over a supply voltage range of +0.9V to +5.5V, supporting both 1.8V and 3.3V USB PHY interfaces as well as legacy 5V systems. This wide range allows direct integration with diverse host and peripheral ICs without level-shifting circuitry. The MAX3202EEWS+T maintains specified ESD performance and leakage current (≤1nA) across this entire voltage span and the full –40°C to +85°C temperature range.
How does the MAX3202EEWS+T achieve ±15kV air-gap ESD protection?
The MAX3202EEWS+T achieves ±15kV air-gap ESD protection through a combination of low-forward-voltage silicon diodes and optimized internal layout that minimizes parasitic inductance. Under a ±15kV IEC 61000-4-2 air-gap discharge, it limits peak clamp voltage to ±100V at 45A pulse current. This performance is validated per JEDEC standards and depends critically on proper PCB layout-including short trace lengths, solid ground planes, and the mandatory 0.1µF VCC bypass capacitor. The MAX3202EEWS+T's BiCMOS process ensures consistent VF and low leakage across conditions.
Can the MAX3202EEWS+T be used for USB 3.0 or higher-speed interfaces?
No, the MAX3202EEWS+T is not recommended for USB 3.0 (5Gbps) or higher-speed interfaces. While its 5pF capacitance is appropriate for USB 2.0 (480Mbps), it exceeds the typical ≤1pF requirement for SuperSpeed differential pairs to avoid signal degradation. The MAX3202EEWS+T is explicitly characterized and qualified for USB and USB 2.0 applications per Maxim's datasheet; use of the MAX3202EEWS+T on USB 3.0 lanes may cause eye closure, jitter increase, or link training failure.
