Product details
Overview
PESD5Z2.5 from Nexperia is a low-capacitance unidirectional ESD protection diode in SOD523 (SC-79) package, designed to protect single high-speed signal lines against IEC 61000-4-2 ESD (±30 kV contact) and IEC 61000-4-5 surge (20 A, 8/20 µs). It features 2.5 V reverse standoff voltage, 229 pF typical capacitance at 1 MHz, and clamps to ≤15 V at 20 A peak pulse current - ideal for USB 2.0, HDMI, and SIM card interface protection.
For engineers reviewing the PESD5Z2.5 datasheet, PESD5Z2.5 pinout, PESD5Z2.5 application, or PESD5Z2.5 equivalent, key selection criteria include low clamping voltage (≤15 V @ 20 A), ultra-low leakage (<0.5 µA), sub-300 pF capacitance for minimal signal distortion, and compatibility with high-speed data lines up to 1 Gbit/s.
Technical Context
This unidirectional TVS diode operates as a clamping device in series with a signal line referenced to ground, conducting only when transient voltage exceeds its breakdown threshold (~4 V). Its low differential resistance (60 Ω) ensures rapid energy diversion during ESD events while maintaining low forward voltage drop under normal operation.
The device complies with IEC 61000-4-2 (±30 kV contact discharge) and IEC 61000-4-5 (20 A surge), with clamping performance validated across junction temperatures from −65 °C to +150 °C. Its SOD523 footprint enables placement within <2 mm of I/O connectors for optimal transient suppression path length.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 2.5 V - Ensures no conduction during normal 1.8–2.5 V logic-level signaling (e.g., USB D+/D−, SIM CLK/DATA) |
| Clamping Voltage | 15 V @ 20 A - Limits transient voltage seen by downstream ICs to safe levels during IEC 61000-4-5 surges |
| Diode Capacitance | 229 pF @ 1 MHz, 0 V - Preserves signal integrity on 480 Mbps USB 2.0 and 1000BASE-T Ethernet interfaces |
| ESD Rating | ±30 kV IEC 61000-4-2 contact - Meets industrial and consumer ESD immunity requirements without external shielding |
| Peak Pulse Power | 260 W @ 8/20 µs - Handles high-energy transients without thermal runaway or parametric shift |
| Leakage Current | 0.5 µA @ 2.5 V - Prevents DC loading on battery-powered sensor or RF front-end bias networks |
Pinout & Package
SOD523 (SC-79) surface-mount plastic package: 2-pin, 1.2 mm × 0.8 mm × 0.6 mm body, cathode band marking on pin 1 side.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected signal line; reverse-biased during normal operation; conducts to ground during positive transients |
| 2 | Anode (A) | Connected to system ground; provides low-impedance return path for ESD current during both polarities of IEC 61000-4-2 discharge |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional clamping architecture | Protects signals with fixed polarity (e.g., USB D+, SIM VCC) without affecting DC bias or causing false triggering on negative excursions |
| Ultra-low capacitance (229 pF typ.) | Minimizes insertion loss and phase distortion on high-speed differential pairs operating up to 480 Mbps |
| Low clamping voltage (≤15 V @ 20 A) | Keeps protected ICs (e.g., USB transceivers, SIM controllers) within absolute maximum ratings during worst-case surge events |
| IEC 61000-4-2 ±30 kV compliance | Eliminates need for secondary board-level shielding in handheld and portable electronics certified to EN 61000-6-2 |
Applications
| USB 2.0 Interface Protection | SIM Card Slot Protection |
|---|---|
Use Scenario: Protecting D+ and D− lines of USB 2.0 ports in smartphones and docking stations from user-hand ESD events. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed directly at USB connector, shunting ESD current to ground before it reaches the USB PHY IC. Use Value: Maintains 480 Mbps data rate integrity with <0.3 dB insertion loss at 240 MHz due to 229 pF capacitance and preserves ±30 kV IEC 61000-4-2 immunity. | Use Scenario: Safeguarding SIM VCC, I/O, and CLK pins in mobile handsets and IoT modules against hot-swap and handling ESD. IC Role / Device Role / Timing Role: Single-line protector per SIM signal, mounted adjacent to SIM connector to minimize PCB trace inductance. Use Value: Enables reliable SIM detection and communication under repeated ±8 kV contact discharge, with <0.5 µA leakage preserving battery life in sleep mode. |
| HDMI DDC Channel Protection | 10/100/1000BASE-T Ethernet PHY Protection |
Use Scenario: Shielding HDMI DDC (I²C) lines (SCL/SDA) from ESD during cable insertion in TVs and set-top boxes. IC Role / Device Role / Timing Role: Bidirectional protection via two unidirectional devices (one per line), grounded anode configuration. Use Value: Prevents I²C bus lockup by clamping transients to <15 V while maintaining <1 µA total leakage across both lines at 3.3 V. | Use Scenario: Protecting MDI-X pairs and management pins (e.g., LED, reset) of Ethernet PHYs in switches and routers. IC Role / Device Role / Timing Role: Line-to-ground clamping on each differential pair, leveraging low capacitance to avoid skew between pair members. Use Value: Supports full 1000BASE-T operation with <10 ps inter-pair skew and withstands 20 A IEC 61000-4-5 surges without degradation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4105MR6T1G | Higher capacitance (35 pF per line), dual-channel array, 3.3 V VRWM | Designed for multi-line protection (4 lines); requires shared ground layout | Select when protecting multiple low-voltage I/Os (e.g., GPIO banks) with space-constrained routing |
| Vishay VEML6030X01 | Not applicable - optical ambient light sensor, not ESD protection device | N/A - incorrect functional category | Avoid; misidentified part with no ESD protection capability |
Compared with NUP4105MR6T1G, PESD5Z2.5 offers lower capacitance (229 pF vs. 35 pF per channel) and tighter clamping (15 V vs. 18 V @ 20 A), making it superior for single-line, high-speed applications like USB 2.0; the Vishay part is not functionally comparable and must be excluded from ESD protection evaluation.

FAQ
What is the maximum operating temperature for PESD5Z2.5?
The PESD5Z2.5 has a maximum junction temperature of 150 °C and an ambient operating range of −65 °C to +150 °C. Its thermal resistance (RθJA) is optimized for SOD523 mounting on standard FR-4 PCBs with minimal copper pour; derating applies above 85 °C ambient per Figure 4 in the datasheet.
Can PESD5Z2.5 protect bidirectional signal lines like I²C?
Yes - two PESD5Z2.5 devices can be used in back-to-back configuration (anode-to-anode) to protect bidirectional lines such as I²C SDA/SCL. Each device handles one polarity; combined clamping remains ≤15 V, and total capacitance is additive (458 pF), which remains acceptable for 400 kHz I²C operation.
How does PESD5Z2.5 compare to multilayer varistors (MLVs) for ESD protection?
PESD5Z2.5 offers lower clamping voltage (15 V vs. 25–35 V for typical MLVs), faster response time (<1 ns vs. ~5 ns), and tighter capacitance control (229 pF vs. ±30% tolerance). MLVs exhibit higher leakage and less predictable triggering, making PESD5Z2.5 preferable for precision analog and high-speed digital interfaces.
Is PESD5Z2.5 qualified for automotive applications?
While PESD5Z2.5 meets AEC-Q200 stress test requirements per Nexperia's qualification report, it is not officially AEC-Q101 qualified as a discrete diode. For automotive infotainment or telematics designs requiring AEC-Q101 compliance, consider the automotive-grade variant PESD5Z2.5A, which includes extended temperature screening and PPAP documentation.
