Product details
Overview
PUSB3AB6Z from Nexperia is a 6-channel ultra-low-capacitance ESD protection diode array designed for SuperSpeed USB 3.1 (10 Gbps), USB 2.0, SD 3.0, and Thunderbolt interfaces. It provides system-level IEC 61000-4-2 Level 4 contact ESD protection (±15 kV) with snapback clamping, 0.15 pF line capacitance per channel, and rail-to-rail clamping in a DFN2111-7 (SOT1358-1) package.
For engineers reviewing the PUSB3AB6Z datasheet, PUSB3AB6Z pinout, PUSB3AB6Z application, or PUSB3AB6Z equivalent, this device is selected for high-speed signal integrity preservation in portable electronics where sub-0.2 pF capacitance, matched trace routing, and robust ±15 kV ESD immunity are mandatory design requirements.
Technical Context
The PUSB3AB6Z employs a snapback-based clamping structure that delivers dynamic resistance as low as 0.4 Ω (TLP, ±1 A), enabling rapid voltage suppression during ESD transients while maintaining minimal signal distortion. Its negative differential resistance behavior reduces clamping voltage to ≤6 V at ±5 A peak pulse current.
All six channels operate independently with identical electrical characteristics: breakdown voltage ≥6 V (1 mA), reverse leakage ≤100 nA at 5 V, and clamping voltage specified for both positive and negative transients under IEC 61000-4-2 and IEC 61000-4-5 conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±15 kV contact discharge per IEC 61000-4-2 Level 4 - ensures robust system-level protection without external TVS cascading |
| Line Capacitance | 0.15 pF typical per channel at 1 MHz/1.5 V - preserves USB 3.1 10 Gbps eye diagram integrity with <0.5 dB insertion loss up to 10 GHz |
| Clamping Voltage | ≤6 V at +5 A / ≤−6 V at −5 A (IEC 61000-4-5 8/20 µs) - limits downstream IC stress below logic-level damage thresholds |
| Dynamic Resistance | 0.4 Ω typical (TLP, ±1 A) - enables fast energy shunting with minimal voltage overshoot during nanosecond-scale ESD events |
| Breakdown Voltage | ≥6 V at 1 mA - guarantees no conduction during normal 3.3 V/5 V interface operation, preventing signal loading |
| Operating Temperature | −40 °C to +85 °C ambient - supports deployment in consumer handhelds and embedded display interfaces |
Pinout & Package
Package: DFN2111-7 (SOT1358-1), 1.1 × 2.1 × 0.5 mm, leadless surface-mount, thermal pad exposed on bottom (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CH1 | ESD protection input/output for first high-speed differential pair (e.g., USB3 TX+/−) |
| 2 | GND | Primary ground reference; any single pin may serve as GND - decouples ESD return path from signal ground planes |
| 3 | CH2 | ESD protection input/output for second high-speed differential pair (e.g., USB3 RX+/−) |
| 4 | CH3 | ESD protection input/output for third high-speed differential pair (e.g., SD DAT0–DAT3 or Thunderbolt lanes) |
| 5 | CH4 | ESD protection input/output for fourth high-speed differential pair (e.g., auxiliary USB2 D+/D− or SD CMD) |
| 6 | CH5 | ESD protection input/output for fifth high-speed signal line (e.g., SD CLK or Thunderbolt reference) |
| 7 | CH6 | ESD protection input/output for sixth high-speed signal line (e.g., USB2 ID or SD VDD sense) |
Key Features
| Feature | Design Value |
|---|---|
| Snapback Clamping Architecture | Enables sub-6 V clamping at ±5 A while maintaining 0.4 Ω dynamic resistance - critical for protecting 1.2 V/1.8 V PHY receivers |
| Rail-to-Rail Diode Configuration | Provides bidirectional clamping between VCC and GND for each channel - eliminates need for external biasing or dual-rail TVS |
| Matched 0.5 mm Trace Spacing | Aligns with standard high-speed PCB layout rules for USB3/Thunderbolt differential pairs - minimizes impedance discontinuity and crosstalk |
| Pass-Through Signal Routing | Input and output pins placed on opposite edges of package - allows straight-through PCB trace routing without vias or stubs |
| Ultra-Thin Profile (0.5 mm max height) | Enables integration into space-constrained mobile form factors including smartphones and ultrathin notebooks |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-capacitance ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1006-04UTG (Littelfuse) | 0.35 pF line capacitance; ±12 kV IEC 61000-4-2; SOT-563 package (1.6 × 1.6 mm) | Larger footprint and higher capacitance limit usable data rate to USB 2.0/SD 2.0 only | Select when cost sensitivity outweighs 10 Gbps support and board space permits larger package |
| ESD56081D05 (ON Semiconductor) | 0.22 pF capacitance; ±15 kV rating; DFN1210-8 package with 8 pins (includes VCC clamp) | Includes dedicated VCC rail clamp but requires external 5 V supply; not suitable for floating-bus interfaces | Choose only if system includes stable 5 V rail and requires combined signal+power rail protection |
Compared with SP1006-04UTG and ESD56081D05, PUSB3AB6Z uniquely delivers 0.15 pF capacitance in a 1.1 × 2.1 mm footprint with true rail-to-rail clamping-enabling USB 3.1 Gen 2 and Thunderbolt 3 compliance without VCC dependency or signal degradation.

FAQ
What is the maximum data rate supported by PUSB3AB6Z?
PUSB3AB6Z is characterized and validated for 10 Gbps operation, matching USB 3.1 Gen 2 (SuperSpeed+) requirements. Eye diagram measurements (Fig 4) confirm full compliance with USB-IF specifications when used on properly impedance-controlled PCB traces with matched 0.5 mm spacing.
Can PUSB3AB6Z be used on USB 2.0-only interfaces?
Yes - PUSB3AB6Z supports USB 2.0 Hi-Speed (480 Mbps) interfaces with identical performance: its 0.15 pF capacitance introduces negligible loading, and ±15 kV ESD protection exceeds USB-IF ESD requirements. Pin assignments allow direct use on D+/D− lines without redesign.
Is an external ground connection required on Pin 2 only?
No - Pin 2 is labeled GND, but the datasheet explicitly states "Any pin can be chosen for ground connection; one pin must be connected to ground." This design allows flexible PCB layout; however, only one GND connection is needed, and thermal pad grounding is optional (non-electrical).
Does PUSB3AB6Z require DC biasing or enable signals?
No - PUSB3AB6Z is a passive, always-active ESD protection device with no enable pin, no power supply, and no DC bias requirements. It operates solely via snapback diode physics and functions across the full −40 °C to +85 °C range without configuration.
