Product details
Overview
PESD5V0U2BT-Q from Nexperia is a bidirectional double ESD protection diode in SOT23 package, designed to safeguard two high-speed data lines against electrostatic discharge up to ±10 kV contact (IEC 61000-4-2 Level 4), with ultra-low capacitance of 2.9 pF (typ.) and reverse standoff voltage of 5 V - deployed in automotive Ethernet, SIM card interfaces, and FireWire signal paths.
For engineers reviewing the PESD5V0U2BT-Q datasheet, PESD5V0U2BT-Q pinout, PESD5V0U2BT-Q application, or PESD5V0U2BT-Q equivalent, key selection criteria include clamping voltage under ESD stress, differential capacitance at 1 MHz, leakage current at 5 V, AEC-Q101 qualification status, and common-cathode dual-diode topology for compact two-line protection.
Technical Context
This device implements a dual-channel, common-cathode bidirectional TVS structure optimized for high-speed signal integrity. Each channel provides symmetrical clamping in both polarities, with typical breakdown voltage of 7 V and clamping voltage ≤12 V at 8 A IPP, enabling robust protection without signal distortion on lines operating up to 1 Gbps.
Its ultra-low 2.9 pF capacitance (measured at 1 MHz, 0 V bias) and sub-100 nA reverse leakage at VRWM = 5 V ensure minimal loading on USB 2.0, HDMI, and 10/100/1000BASE-T Ethernet lanes. The SOT23 footprint supports automated placement and reflow while maintaining thermal stability up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage (VRWM) | 5 V - Maximum continuous working voltage before conduction begins; defines safe operating range for 3.3 V and 5 V data buses. |
| Diode Capacitance (Cd) | 2.9 pF (typ.) at 1 MHz, 0 V - Enables use on >500 Mbps differential lines without measurable signal rise-time degradation. |
| ESD Withstand (IEC 61000-4-2) | ±10 kV contact / ±15 kV air - Meets automotive and industrial immunity requirements for connector-facing protection. |
| Reverse Leakage Current (IRM) | 5 nA (typ.) at 5 V - Ensures negligible DC loading on low-power sensor or SIM card I/O lines. |
| Breakdown Voltage (VBR) | 7 V (typ.) at 5 mA - Defines onset of avalanche conduction; ensures margin above VRWM for reliable turn-on during transients. |
| Junction Temperature (Tj) | 150 °C max - Supports operation in under-hood automotive environments and thermally constrained portable enclosures. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 mm × 1.3 mm × 1.0 mm body height; optimized for high-density PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode of Diode 1 | Connects to first protected line (e.g., USB D+); conducts transient current to common cathode when line goes negative relative to ground. |
| 2 (K2) | Cathode of Diode 2 | Connects to second protected line (e.g., USB D−); enables independent bidirectional clamping per line with shared return path. |
| 3 (CC) | Common Cathode | Single low-inductance connection point to system ground; minimizes loop area and improves ESD energy dissipation efficiency. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional dual-line protection | Two independent ESD channels share one ground terminal, reducing PCB real estate vs. discrete diodes and eliminating mismatched clamping thresholds. |
| Ultra-low 2.9 pF capacitance | Preserves signal integrity on high-speed interfaces (e.g., FireWire, Ethernet PHY) without requiring trace length compensation or equalization. |
| AEC-Q101 qualified | Validated for automotive applications including infotainment head units and telematics modules, with full temperature cycling and HTRB testing. |
| 10 kV contact ESD rating | Exceeds IEC 61000-4-2 Level 4 requirement, ensuring reliability in manufacturing handling and end-user environments with frequent plug/unplug cycles. |
| Sub-100 nA leakage at 5 V | Prevents battery drain in always-on portable electronics (e.g., SIM card slots, Bluetooth accessories) over multi-year service life. |
Applications
| USB 2.0 Interface Protection | Automotive Ethernet PHY Protection |
|---|---|
|
Use Scenario: Protecting D+ and D− lines of USB 2.0 ports in vehicle infotainment systems exposed to repeated hot-plug events and ESD from user interaction. IC Role / Device Role / Timing Role: Dual-channel bidirectional clamp placed within 3 mm of USB connector, shunting ESD pulses to chassis ground before reaching the USB transceiver IC. Use Value: Maintains <1.5% signal attenuation at 480 Mbps due to 2.9 pF capacitance, while surviving ≥10,000 insertion cycles per AEC-Q200. |
Use Scenario: Safeguarding 100BASE-T1 or 1000BASE-T1 PHY differential pairs in ADAS domain controllers where ESD immunity must meet ISO 10605. IC Role / Device Role / Timing Role: Common-cathode dual diode placed at Ethernet magnetics interface, clamping common-mode transients before entering transformer-coupled PHY inputs. Use Value: Enables compliance with automotive EMC test levels (±8 kV contact) without degrading 100 MHz bandwidth or introducing jitter via parasitic capacitance. |
| SIM Card Slot Protection | FireWire (IEEE 1394) Data Line Protection |
|
Use Scenario: Shielding VCC, I/O, and CLK pins of embedded SIM (eSIM) sockets in telematics control units from ESD during module replacement or field servicing. IC Role / Device Role / Timing Role: One PESD5V0U2BT-Q protects two critical SIM lines (e.g., I/O + CLK), leveraging low leakage (<5 nA) to avoid disrupting secure boot sequences. Use Value: Prevents false resets or authentication failures caused by ESD-induced latch-up, validated across −40 °C to +105 °C ambient operating range. |
Use Scenario: Securing bidirectional data pairs in legacy FireWire 400/800 ports on professional audio/video equipment subject to studio-floor ESD events. IC Role / Device Role / Timing Role: Dual-diode array installed adjacent to FireWire connector, providing symmetrical clamping on TPB+ and TPB− lines with matched Cd <3.5 pF. Use Value: Eliminates packet loss during live recording sessions by limiting clamping voltage to ≤12 V at 8 A, preserving eye diagram opening at 400 Mbps. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor ESDE0504P2T5G | Higher capacitance (5.5 pF typ.), same 5 V VRWM and ±12 kV ESD rating; uses SOT-553 package (smaller footprint but higher thermal resistance). | Better suited for space-constrained consumer wearables; less optimal for >200 Mbps signals due to higher Cd. | Select when board area is critical and data rate ≤100 Mbps; verify thermal derating for sustained surge events. |
| Vishay VEML6030X01 | Not applicable - this is an ambient light sensor; excluded from equivalence assessment. | N/A | Not a valid alternative; no functional or electrical overlap with PESD5V0U2BT-Q. |
Compared with ESDE0504P2T5G, PESD5V0U2BT-Q offers 2.6 pF lower capacitance for superior high-speed fidelity, while its SOT23 package provides better thermal dissipation than SOT-553 - making it preferred for automotive Ethernet and USB 2.0. No other verified dual-diode ESD protector matches its combination of AEC-Q101, 2.9 pF, and common-cathode layout.

FAQ
What is the maximum clamping voltage of PESD5V0U2BT-Q during an 8 A ESD pulse?
The typical clamping voltage (VCL) is ≤12 V at 8 A peak pulse current (IPP), measured per IEC 61000-4-2 waveform. This value ensures protected ICs downstream-such as USB transceivers or Ethernet PHYs-remain below their absolute maximum input voltage ratings during transient events.
Can PESD5V0U2BT-Q be used for unidirectional signal lines?
No-it is strictly a bidirectional device with symmetrical V-I characteristics. Its common-cathode configuration requires both protected lines to reference the same ground potential. For unidirectional protection (e.g., power rail to ground), a single-channel unidirectional TVS like PESD5V0R1B should be selected instead.
How does the 2.9 pF capacitance impact 1000BASE-T1 Ethernet performance?
At 600 MHz (the upper frequency limit of 1000BASE-T1), 2.9 pF introduces <0.1 dB insertion loss and <0.5° phase shift across the differential pair-well within IEEE 802.3bp compliance margins. Layout best practices (short traces, ground stitching vias) further minimize any residual impedance discontinuity.
Is the SOT23 package lead-free and RoHS-compliant?
Yes-PESD5V0U2BT-Q is manufactured using lead-free solderable terminations and fully complies with EU RoHS Directive 2011/65/EU and REACH SVHC regulations. The SOT23 package meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) for unlimited floor life at ≤30 °C/85% RH.
