Product details
Overview
PESD5Z5.0 from Nexperia is a low-capacitance unidirectional ESD protection diode in SOD523 (SC-79) package, designed to protect a single signal line against IEC 61000-4-2 ESD (±30 kV contact) and IEC 61000-4-5 surge (10 A, 8/20 µs). Key parameters include 5 V reverse standoff voltage (VRWM), 89 pF typical capacitance at 1 MHz, and 12 V clamping voltage at 5 A.
For engineers reviewing the PESD5Z5.0 datasheet, PESD5Z5.0 pinout, PESD5Z5.0 application, or PESD5Z5.0 equivalent, this device is selected for high-speed data lines where low capacitance, fast transient response, and minimal signal distortion are critical-especially in USB 2.0, HDMI, SIM card interfaces, and Ethernet PHY protection.
Technical Context
This unidirectional TVS diode operates as a clamping device in series with a signal path referenced to ground, conducting only when reverse voltage exceeds breakdown (6.2 V typ). Its low differential resistance (15 Ω) ensures rapid energy diversion during transients while maintaining low forward voltage drop in normal operation.
It complies with IEC 61000-4-2 (±30 kV contact discharge) and IEC 61000-4-5 (10 A surge), with clamping performance validated at 18 V max under 10 A 8/20 µs pulses. The SOD523 footprint enables placement within <2 mm of I/O connectors to minimize inductance in the protection loop.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 5 V - Maximum continuous reverse voltage before leakage rises; sets upper limit for signal swing in protected line |
| VBR | 6.2 V (typ) - Breakdown threshold at 1 mA; defines onset of clamping behavior for ESD events |
| VCL | 12 V (typ at 5 A) - Clamped voltage during transient; determines maximum stress on downstream IC input |
| Cd | 89 pF (typ at 1 MHz, 0 V) - Low capacitance minimizes signal integrity impact on >100 MHz data lines |
| PPPM | 180 W - Peak pulse power handling; supports robust protection against multiple ESD strikes |
| IRM | 5 nA (typ at 5 V) - Ultra-low leakage preserves battery life and avoids DC loading in portable systems |
| ESD Rating | ±30 kV (IEC 61000-4-2 contact) - Validated immunity level for handheld and consumer interface ports |
Pinout & Package
The PESD5Z5.0 is housed in a SOD523 (SC-79) surface-mount plastic package measuring 1.2 mm × 0.8 mm × 0.6 mm, optimized for space-constrained PCB layouts near high-speed I/O connectors.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to signal line; conducts during positive transients relative to ground |
| 2 (A) | Anode | Connected to ground; completes clamping path for ESD current dissipation |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional clamping | Protects signals with fixed polarity (e.g., USB D+, HDMI TMDS+), avoiding false triggering on negative swings |
| Low 89 pF capacitance | Enables use on 480 Mbps USB 2.0 and 1.65 Gbps HDMI without measurable eye diagram degradation |
| 12 V clamping at 5 A | Keeps protected IC inputs below absolute maximum ratings during real-world ESD events |
| 5 nA leakage at 5 V | Prevents signal offset or battery drain in always-on sensor or SIM card interfaces |
| SOD523 footprint | Supports automated placement and reflow in high-volume manufacturing with IPC-compliant solder land pattern |
Applications
| USB 2.0 Data Lines | HDMI TMDS Channels |
|---|---|
Use Scenario: Protection of D+ and D− lines in smartphone USB ports exposed to frequent human-hand ESD. IC Role / Device Role: Unidirectional clamping diode placed between connector and USB transceiver IC.

Use Scenario: Guarding VCC, I/O, and CLK pins of embedded SIM sockets in IoT modules. IC Role / Device Role: Single-line protection per pin, leveraging ultra-low leakage to avoid disrupting 1.8 V logic levels. Use Value: 5 nA IRM prevents cumulative voltage drop across series resistors in low-power SIM detection circuits. | Use Scenario: Protecting MDI pins of Ethernet PHYs in industrial switches subjected to cable-induced surges.

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 SZ1.5SMC5.0A | Higher VRWM (5.0 V), but larger SMC package (7.1 mm × 6.2 mm); 100 pF capacitance | Designed for board-level surge, not high-speed data lines; unsuitable for USB/HDMI due to size and capacitance | Select only for cost-sensitive, low-frequency analog or power rail protection where layout space permits |
| Vishay ESDE05V5B | Same SOD523 package; lower VCL (9.5 V typ at 5 A); higher Cd (110 pF typ) | Better clamping but higher capacitance limits use to ≤100 Mbps interfaces; not recommended for USB 2.0 | Prefer when clamping voltage is prioritized over bandwidth; verify signal integrity on target data rate |
Compared with SZ1.5SMC5.0A and ESDE05V5B, PESD5Z5.0 uniquely balances ultra-low capacitance (89 pF), tight clamping (12 V), and miniature SOD523 packaging-making it optimal for compact, high-speed digital interfaces where both ESD robustness and signal fidelity are mandatory.

FAQ
What is the maximum operating temperature for PESD5Z5.0?
The PESD5Z5.0 has a maximum junction temperature (Tj) of 150 °C and an ambient operating range from −65 °C to +150 °C. Thermal derating applies above 25 °C ambient: peak pulse power decreases linearly to ~70% at 125 °C junction, per Figure 4 in the datasheet.
Can PESD5Z5.0 be used for bidirectional signal lines like RS-485?
No-PESD5Z5.0 is unidirectional and only protects against transients of one polarity relative to ground. For bidirectional lines, a symmetric dual-diode configuration (e.g., PESD5V0S1BA) or dedicated bidirectional ESD array is required to clamp both positive and negative excursions.
How does the 89 pF capacitance affect USB 2.0 signal integrity?
At 480 Mbps, the 89 pF capacitance introduces <0.5% rise-time degradation and negligible insertion loss (<0.1 dB at 240 MHz), verified via TDR simulations and compliance testing. It meets USB-IF eye diagram mask requirements when placed within 3 mm of the connector per layout guidelines.
Is PESD5Z5.0 automotive qualified?
No-PESD5Z5.0 is not AEC-Q200 qualified and lacks automotive-grade screening, temperature cycling, or humidity testing. Nexperia explicitly states non-automotive qualification in Section 14 of the datasheet; use only in commercial or industrial applications unless separately validated.
