Product details
Overview
PESD4USB5U-TTSX from Nexperia is a unidirectional ESD protection diode array designed for high-speed serial interfaces including SuperSpeed USB 3.2 (10 Gbps), HDMI 2.0, DisplayPort, eSATA, LVDS, and GMSL SerDes. It delivers ±15 kV IEC 61000-4-2 contact ESD protection, 0.5 pF channel capacitance, 0.4 Ω dynamic resistance, 5 V reverse standoff voltage, and AEC-Q101 qualification for automotive infotainment and camera links.
For engineers reviewing the PESD4USB5U-TTSX datasheet, PESD4USB5U-TTSX pinout, PESD4USB5U-TTSX application, or PESD4USB5U-TTSX equivalent, key selection criteria include ultra-low capacitance for signal integrity, snap-back clamping behavior for low-voltage rail protection, side-wettable flanks for AOI compatibility, and matched trace spacing for high-speed PCB layout.
Technical Context
This device implements a deep snap-back clamping structure with negative dynamic resistance, enabling sub-3.5 V clamping during ±5 A transients while maintaining 0.4 Ω dynamic resistance per channel. Its architecture targets transient suppression without signal distortion on differential high-speed buses.
Each of the four protected channels operates independently with 1 mA breakdown voltage ≥6 V, reverse leakage ≤100 nA at 5 V, and stable 0.4–0.5 pF capacitance across 0–5 V bias - critical for preserving impedance matching in 10 Gbps USB 3.2 and GMSL links.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±15 kV IEC 61000-4-2 contact discharge - exceeds Level 4, ensuring robust system-level immunity in automotive and industrial environments |
| Channel Capacitance | 0.5 pF @ 1 MHz, 0 V - preserves signal integrity on 10 Gbps USB 3.2 and HDMI 2.0 differential pairs |
| Dynamic Resistance | 0.4 Ω @ 10 A TLP pulse - enables low clamping voltage (±3.5 V) under fast ESD events |
| Reverse Standoff Voltage | 5 V - compatible with 3.3 V and 5 V I/O rails without leakage-induced signal degradation |
| Breakdown Voltage | Min 6 V @ 1 mA - provides margin above operating voltage while triggering reliably during ESD |
| AEC-Q101 Qualified | Qualified for automotive applications - validated for temperature cycling, humidity, and mechanical stress per AEC standard |
Pinout & Package
Encapsulated in a DFN2510D-10 (SOT1165D) leadless plastic package measuring 2.5 mm × 1.0 mm × 0.75 mm with 0.5 mm pitch and side-wettable flanks for automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CH1 | ESD protection input for first high-speed differential pair (e.g., USB3 TX+/−) |
| 2 | CH2 | ESD protection input for second high-speed differential pair (e.g., USB3 RX+/−) |
| 3 | GND | Primary ground connection for ESD current return path |
| 4 | CH3 | ESD protection input for third high-speed differential pair (e.g., HDMI TMDS0+/−) |
| 5 | CH4 | ESD protection input for fourth high-speed differential pair (e.g., HDMI TMDS1+/−) |
| 6–7, 9–10 | n.c. | No internal connection - electrically isolated, must remain unconnected on PCB |
| 8 | GND | Secondary ground connection - improves thermal dissipation and reduces ground loop inductance |
Key Features
| Feature | Design Value |
|---|---|
| Pass-through signal routing | Linear pin arrangement (CH1–CH4–GND–n.c.–n.c.–GND–n.c.–n.c.) minimizes trace stubs and maintains controlled impedance on high-speed lines |
| Side-wettable flanks (SWF) | Exposed copper on package edges enables reliable AOI detection of solder joint quality in automated assembly |
| Matched 0.5 mm trace spacing | Pin pitch matches standard high-speed PCB routing grids, eliminating need for fanout vias near connector interface |
| Ultra-low leakage | ≤100 nA reverse current at 5 V ensures no DC loading on 3.3 V/5 V data lines during normal operation |
Applications
| Automotive Infotainment | HDMI 2.0 Interface Protection |
|---|---|
Use Scenario: Protecting USB 3.2 Gen 2 (10 Gbps) and DisplayPort lanes in vehicle head units and rear-seat entertainment systems. IC Role / Device Role / Timing Role: Unidirectional ESD clamp placed directly at board edge connectors to shunt transient energy before reaching SoC PHY. Use Value: Prevents latch-up or damage to USB 3.2 SerDes blocks during hot-plug events or ESD exposure in service bays. | Use Scenario: Safeguarding HDMI 2.0 TMDS differential pairs between media processors and display modules in automotive dashboards. IC Role / Device Role / Timing Role: Four-channel ESD suppressor aligned with HDMI's three TMDS data lanes + clock lane, each with independent clamping. Use Value: Maintains <0.5 pF capacitance per channel to avoid signal rise-time degradation and eye-diagram closure at 6 Gbps. |
| GMSL SerDes Links | eSATA External Storage |
Use Scenario: ESD protection for Gigabit Multimedia Serial Link (GMSL) serializer/deserializer connections between ADAS cameras and domain controllers. IC Role / Device Role / Timing Role: High-bandwidth transient suppressor placed adjacent to GMSL connectors to absorb ±15 kV contact discharges without affecting jitter budget. Use Value: Enables compliance with ISO 10605 (150 pF/330 Ω) while sustaining <1 ps added jitter on 3.125 Gbps serialized video streams. | Use Scenario: Shielding external Serial ATA (eSATA) ports on industrial PCs and docking stations against user-handling ESD. IC Role / Device Role / Timing Role: Dual-channel bidirectional-capable protection (via unidirectional configuration) for eSATA TX/RX differential pairs. Use Value: Provides 7 A peak pulse current handling (IEC 61000-4-5) to survive multiple ESD strikes without parameter shift or failure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E05U06DQAR | 0.6 pF capacitance, ±12 kV IEC 61000-4-2, 3.6 V VRWM, 0.55 Ω Rdyn | Lower ESD rating and higher capacitance limit use to USB 2.0 or 3.0 (5 Gbps), not 10 Gbps | Select when cost sensitivity outweighs 10 Gbps support and AEC-Q101 is not required |
| SP1006-04UTG | 0.35 pF capacitance, ±15 kV IEC 61000-4-2, 5.5 V VRWM, 0.3 Ω Rdyn, non-AEC-Q101 | Superior capacitance and clamping but lacks automotive qualification and SWF packaging | Select for non-automotive 10 Gbps designs where AOI is not mandatory and lower clamping voltage is prioritized |
Compared with TPD4E05U06DQAR and SP1006-04UTG, PESD4USB5U-TTSX uniquely combines AEC-Q101 qualification, side-wettable flanks for production traceability, and 0.5 pF/0.4 Ω performance optimized for 10 Gbps automotive SerDes links - making it the only option qualified for both GMSL and USB 3.2 Gen 2 in production vehicles.

FAQ
What is the maximum operating temperature for PESD4USB5U-TTSX?
The junction temperature rating is 150 °C, and ambient operating range extends from −55 °C to +150 °C. This wide range supports deployment in engine bay proximity or under-hood infotainment modules where thermal management is constrained. The device maintains specified clamping voltage and leakage performance across this full range.
Can PESD4USB5U-TTSX be used for bidirectional signal lines like USB 2.0 D+ and D−?
Yes - although unidirectional in construction, it can protect bidirectional lines by connecting anode to signal and cathode to ground. Its 6 V minimum breakdown voltage and 5 V reverse standoff ensure safe operation on 3.3 V USB 2.0 lines, and its 0.5 pF capacitance avoids signal integrity issues at 480 Mbps.
Why does PESD4USB5U-TTSX have two GND pins (pins 3 and 8)?
Pins 3 and 8 provide dual ground paths to reduce inductance in the ESD current return loop, improving clamping response time and lowering peak voltage overshoot during fast transients. This dual-GND layout also enhances thermal dissipation and supports higher peak pulse current handling (7 A per IEC 61000-4-5).
Is the marking code 'B5U' sufficient to identify PESD4USB5U-TTSX on the PCB?
Yes - per Nexperia's marking table, 'B5U' is the unique top-side laser mark for PESD4USB5U-TTSX in SOT1165D packaging. This code is verified in production and traceable to the full part number via Nexperia's lot documentation and Aetrix's certified sourcing records.
