Product details
Overview
MAX13208EALB+T from Maxim Integrated is an 8-channel, low-capacitance (6pF), ±30kV IEC 61000-4-2 air-gap ESD protection diode array in a 10-pin µDFN (2mm × 2mm) package, designed to safeguard high-speed data lines such as USB 2.0, FireWire®, and SVGA video interfaces against electrostatic discharge events.
For engineers reviewing the MAX13208EALB+T datasheet, MAX13208EALB+T pinout, MAX13208EALB+T application, or MAX13208EALB+T equivalent, this device delivers verified ±15kV HBM and ±30kV air-gap ESD protection with sub-1nA leakage, 0.9V–16V supply range, and automotive-grade operation from –40°C to +125°C.
Technical Context
The MAX13208EALB+T implements a dual-diode per channel architecture-each I/O line connects to both VCC and GND via steering diodes-to clamp positive transients to VCC + VF and negative transients to –VF during ESD events. It operates without external biasing and relies on the host system's VCC rail for clamping path completion.
Clamp voltage is defined by forward diode drop plus supply voltage under positive stress (VC = VCC + VF), and –VF under negative stress, with parasitic inductance critically affecting real-world performance. The device requires a 0.1µF ceramic bypass capacitor between VCC and GND placed adjacent to its pins to maintain effective clamping at ±120V (IEC air-gap, 90A pulse).
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 exposed connectors in harsh environments. |
| Channel Count | 8 independent ESD-protected I/O channels - matches full-port protection needs for multi-lane interfaces like SVGA or 8-line data buses. |
| Input Capacitance | 6pF per channel at 5V bias and 1MHz - preserves signal integrity on USB 2.0 (480Mbps) and FireWire® (400Mbps) links. |
| Leakage Current | ≤1nA at –40°C to +50°C; ≤1µA at –40°C to +125°C - avoids loading of high-impedance analog or low-power digital inputs. |
| Supply Voltage Range | +0.9V to +16V - supports single-supply operation across 1.8V, 3.3V, 5V, and 12V systems without level-shifting. |
| Operating Temperature | –40°C to +125°C - qualified for automotive infotainment, industrial displays, and under-hood connectivity modules. |
| Clamp Voltage (IEC Air-Gap) | +VCC +120V / –120V at 90A pulse - defines maximum transient overvoltage seen by downstream ICs during worst-case ESD strike. |
Pinout & Package
MAX13208EALB+T is housed in a 10-pin µDFN package (2mm × 2mm × 0.8mm, pkg code L1022-1), with exposed thermal pad (not electrically connected). Pin 1 is marked by a dot or beveled corner; the package is lead-free and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 4, 6, 7, 9 | I/O_ (Channels 1–8) | ESD-protected bidirectional signal terminals; each connects internally to VCC and GND via steering diodes. |
| 2, 5, 8, 10 | N.C. | No internal connection - must remain unconnected on PCB; no routing or copper fill required. |
| VCC (Pin 10) | Power-Supply Input | Bias rail for positive-transient clamping path; requires 0.1µF low-ESR ceramic bypass capacitor to GND, placed within 2mm. |
| GND (Pin 1) | Ground Reference | Return path for negative-transient current; must connect to low-inductance ground plane with minimal trace length. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4202W1T2G | 4-channel, 5.5pF, ±30kV IEC, SOT-363 package (2.2mm × 2.4mm), 30V VBR, 1.5A peak pulse current. | Limited to 4 channels; larger footprint; lower clamp voltage (+22V/–12V at 1A) but lower surge rating. | Select when board space allows larger package and 4-channel count suffices; not suitable for 8-line SVGA or full-port USB 2.0. |
| STMicroelectronics ESDALY12-1U2 | 8-channel, 12pF, ±30kV IEC, 10-lead µDFN (2.5mm × 1.0mm), 12V working voltage, 10A peak pulse. | Double the input capacitance (12pF vs. 6pF); incompatible with USB 2.0 eye diagram requirements; smaller width but longer length. | Choose only for lower-speed interfaces (e.g., UART, I²C) where capacitance sensitivity is low; avoid for high-speed data lines protected by MAX13208EALB+T. |
Compared with NUP4202W1T2G and ESDALY12-1U2, MAX13208EALB+T uniquely combines 8-channel count, 6pF capacitance, and automotive temperature range in a compact 2mm × 2mm µDFN - making it the only option qualified for USB 2.0, FireWire®, and SVGA protection without signal degradation or layout compromise.

FAQ
What is the exact pin configuration of MAX13208EALB+T?
The MAX13208EALB+T uses a 10-pin µDFN package with pins 1, 3, 4, 6, 7, and 9 assigned to I/O channels (I/O1–I/O8), pin 10 as VCC, pin 1 as GND, and pins 2, 5, 8, and 10 designated N.C. The top mark "AAD" confirms the MAX13208E variant. Pin 1 is located at the beveled corner; the exposed thermal pad is non-functional and may be left floating or grounded for mechanical stability.
Does MAX13208EALB+T require an external power supply to function?
Yes - MAX13208EALB+T requires a DC supply connected to its VCC pin (Pin 10) to enable positive-transient clamping. The device steers ESD current to VCC during positive pulses and to GND during negative pulses. No external bias is needed for GND-path conduction, but VCC must be present and bypassed with a 0.1µF ceramic capacitor for full ±30kV IEC 61000-4-2 performance.
Can MAX13208EALB+T be used on 1.8V logic interfaces?
Yes - MAX13208EALB+T operates across +0.9V to +16V, fully supporting 1.8V systems. Its 6pF capacitance and sub-1nA leakage at low temperatures ensure minimal loading on 1.8V GPIOs and I²C/SPI lines. Clamp voltage remains VCC + VF (~2.4V) for positive transients, well within safe margins for 1.8V IO structures.
How does MAX13208EALB+T differ from MAX13204EALT+?
MAX13208EALB+T provides 8 protected channels in a 10-pin µDFN (2mm × 2mm), whereas MAX13204EALT+ offers 4 channels in a 6-pin µDFN (2mm × 2mm). Both share identical 6pF capacitance, ±30kV IEC rating, and –40°C to +125°C range, but MAX13208EALB+T supports denser port protection - e.g., full SVGA (5 lines) + sideband signals - without stacking multiple devices.
Is MAX13208EALB+T compliant with AEC-Q200?
MAX13208EALB+T is specified over the automotive temperature range (–40°C to +125°C) and packaged in a qualified µDFN, but Maxim's official documentation does not list AEC-Q200 qualification for this specific part. For AEC-Q200–mandated designs, users must consult Maxim's latest reliability reports or consider explicitly qualified alternatives - MAX13208EALB+T meets functional automotive operating conditions but lacks formal stress-test certification.
