Product details
Overview
PESD5V0U1UT,215 from Nexperia is a unidirectional ultra-low-capacitance ESD protection diode in SOT23 (TO-236AB) package, designed to safeguard single high-speed data lines against IEC 61000-4-2 level 4 ESD (up to 30 kV contact), with 5.0 V reverse stand-off voltage, 0.6 pF typical capacitance, and 21 V clamping voltage at 5 A surge current. It is deployed in Ethernet PHY interfaces, FireWire ports, and USB 2.0 signal paths where signal integrity and transient immunity are critical.
For engineers reviewing the PESD5V0U1UT,215 datasheet, PESD5V0U1UT,215 pinout, PESD5V0U1UT,215 application, or PESD5V0U1UT,215 equivalent, this device is selected for high-speed line protection requiring sub-1 pF capacitance, low leakage (<100 nA at 5 V), and robust 8/20 µs surge handling up to 80 W - key criteria for 10/100/1000BASE-T, HDMI, and industrial serial interface designs.
Technical Context
The PESD5V0U1UT,215 integrates a primary ESD protection diode and a cathode-compensation diode in a three-terminal SOT23 configuration to achieve effective differential capacitance of 0.6 pF at 1 MHz and 0 V bias. Its unidirectional architecture provides asymmetric clamping: forward conduction initiates at ~7.6 V (typical breakdown), while reverse stand-off holds at 5.0 V with <0.03 µA leakage.
It meets IEC 61000-4-2 (±30 kV contact), IEC 61000-4-5 (8/20 µs, 5 A peak pulse), and MIL-STD-883 HBM (±10 kV) standards. The device operates across −65 °C to +150 °C ambient and delivers 21 V clamping under 5 A transient current, enabling reliable protection without signal distortion in gigabit data links.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage (VRWM) | 5.0 V - Maximum continuous operating voltage before leakage rises significantly; sets safe margin above 3.3 V/5 V logic rails. |
| Diode Capacitance (Cd) | 0.6 pF (typ) at 1 MHz, 0 V - Enables minimal signal attenuation and phase shift on >500 Mbps differential lines like USB 2.0 or Ethernet MDI. |
| Clamping Voltage (VCL) | 21 V at IPP = 5 A (8/20 µs) - Limits transient overvoltage seen by downstream PHY ICs during surge events. |
| ESD Withstand (IEC 61000-4-2) | 30 kV contact discharge - Exceeds level 4 requirement (8 kV contact), ensuring robustness against human-body-model ESD in field-deployed equipment. |
| Peak Pulse Power (PPP) | 80 W (8/20 µs) - Sustains transient energy without thermal failure in short-duration surges common in LAN connectors and docking stations. |
| Breakdown Voltage (VBR) | 7.6 V (typ) at 5 mA - Defines sharp turn-on threshold for fast clamping response, minimizing time spent in high-impedance state during transients. |
| Reverse Leakage (IRM) | 0.03 µA (typ) at VRWM = 5 V - Negligible DC loading on high-impedance receivers, preserving bias stability in analog front-ends and reference circuits. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-pin, 2.8 mm × 1.4 mm footprint, 1.1 mm height, gull-wing leads, JEDEC MS-012 compliant. RoHS-compliant, halogen-free, rated for reflow per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode of main ESD diode | Connected to protected line; conducts transient current to ground when voltage exceeds VBR. |
| 2 | Cathode of compensation diode | Provides capacitance balancing to reduce effective line-to-line capacitance; tied to same protected line as Pin 1 in standard use. |
| 3 | Common anode | Internally connected anodes of both diodes; must be connected to system ground for proper clamping operation. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance topology | 0.6 pF effective capacitance achieved via dual-diode cathode-compensated structure - preserves signal rise/fall times in >1 Gbps interfaces. |
| High ESD immunity | 30 kV contact discharge rating per IEC 61000-4-2 - eliminates need for secondary board-level shielding in consumer-grade USB and Ethernet ports. |
| Low clamping voltage | 21 V at 5 A surge - keeps protected IC's absolute maximum input voltage within safe margin, reducing risk of gate oxide damage in PHY transceivers. |
| Thermal robustness | 150 °C max junction temperature - supports operation in enclosed industrial enclosures and automotive infotainment head units without derating. |
| Compact SMT form factor | SOT23 footprint enables placement within 2 mm of RJ45 connector or USB Type-A receptacle - minimizes PCB trace inductance and improves ESD path impedance. |
Applications
| 10/100/1000BASE-T Ethernet Interface | FireWire (IEEE 1394) Port Protection |
|---|---|
Use Scenario: Protecting twisted-pair differential signals (MDI/MDI-X) in enterprise switches and PoE-powered access points exposed to cable-discharge events. IC Role / Device Role / Timing Role: Unidirectional line protector placed between magnetics and PHY IC; clamps common-mode surges before they reach transformer center-taps or receiver inputs. Use Value: 0.6 pF capacitance prevents skew between differential pairs, maintaining TDR impedance match and reducing bit-error rate in full-duplex gigabit operation. |
Use Scenario: Safeguarding 400 Mbps bidirectional data lanes in digital camcorders and audio interfaces subjected to repeated hot-plug ESD. IC Role / Device Role / Timing Role: Single-line ESD clamp on each data pair (TPA/TPB), with Pin 3 grounded and Pins 1+2 tied to respective signal lines. Use Value: 21 V clamping ensures FireWire PHY (e.g., TSB41AB2) remains below its 24 V abs-max rating during ±15 kV contact discharge, preventing link reset or register corruption. |
| USB 2.0 High-Speed Data Lines | Industrial RS-485 Transceiver Interface |
Use Scenario: Shielding D+ and D− lines in host controllers and peripheral hubs against ESD from user-handled cables in medical and test equipment. IC Role / Device Role / Timing Role: One PESD5V0U1UT,215 per line, mounted adjacent to USB connector; anode (Pin 3) routed directly to chassis ground plane. Use Value: Sub-1 pF capacitance avoids degrading 480 Mbps eye diagram opening, meeting USB-IF compliance for jitter and rise-time specifications. |
Use Scenario: Protecting half-duplex differential bus lines in factory automation PLCs and motor drives exposed to long-cable induced surges. IC Role / Device Role / Timing Role: Paired devices in anti-parallel configuration (two PESD5V0U1UT,215) for bidirectional common-mode suppression on A/B lines. Use Value: Dual-device arrangement achieves symmetrical clamping (<25 V) and extends surge capability beyond single-device 80 W limit, supporting IEC 61000-4-5 level 3 (2 kV) requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional high-speed ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5V3U1U,215 | Higher VRWM (5.3 V), slightly higher Cd (0.8 pF typ), identical SOT23 pinout and 30 kV ESD rating. | Better suited for 5 V tolerant I/O with tighter noise margins; less ideal for 3.3 V systems with narrow VCC–VIO headroom. | Select when protecting 5 V logic rails where 0.3 V extra stand-off improves noise immunity without sacrificing speed. |
| TPD2E001DRYR | Lower VCL (14 V at 5 A), higher Cd (1.0 pF), dual-channel in SOT-5X3, same 30 kV ESD rating. | Optimized for space-constrained dual-line applications (e.g., HDMI DDC); requires different layout due to 5-pin package and internal dual-diode structure. | Choose for dual-line protection where board area is premium and 14 V clamping justifies 0.4 pF capacitance penalty. |
Compared with ESD5V3U1U,215 and TPD2E001DRYR, the PESD5V0U1UT,215 offers the lowest capacitance (0.6 pF) among SOT23 unidirectional protectors, making it optimal for highest-speed single-line applications where signal fidelity is prioritized over multi-line integration or ultra-low clamping.

FAQ
What is the maximum recommended trace length between PESD5V0U1UT,215 and the protected connector?
Trace length should not exceed 2 mm from the device's Pin 1/Pin 2 to the connector pad, with direct low-inductance grounding of Pin 3 to a solid ground plane using ≥2 vias. Longer traces increase inductive impedance, raising clamped voltage during fast ESD transients and risking downstream IC damage.
Can PESD5V0U1UT,215 be used for bidirectional signal lines like RS-485 without external components?
No - PESD5V0U1UT,215 is unidirectional and protects only positive transients relative to ground. For bidirectional lines, two units must be configured in anti-parallel (Pin 1 of Device A to Pin 2 of Device B, both Pins 3 grounded) to provide symmetrical clamping on both polarities of the differential pair.
Does PESD5V0U1UT,215 require derating at elevated ambient temperatures?
Yes - while rated for 150 °C junction temperature, its peak pulse power drops to 60 W at Tamb = 85 °C and 40 W at Tamb = 125 °C per IEC 61000-4-5 derating curves. System-level thermal design must ensure adequate copper pour and airflow to maintain Tj ≤ 130 °C during sustained surge conditions.
How does the dual-diode structure affect PCB layout versus conventional single-diode ESD protectors?
The dual-cathode (Pins 1 & 2) structure requires both pins to connect to the same protected line - unlike single-diode parts that use one pin for line and one for ground. This eliminates floating nodes but mandates careful routing to avoid stubs; unused pins must never be left open or capacitively coupled to adjacent nets.
