Product details
Overview
PESD5Z5.0-Q 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 (10 A, 8/20 µs). It delivers 12 V clamping voltage at 10 A, 89 pF typical capacitance at 0 V, and 5 nA reverse leakage at 5 V - enabling robust protection for USB 2.0, HDMI, and SIM card interfaces.
For engineers reviewing the PESD5Z5.0-Q datasheet, PESD5Z5.0-Q pinout, PESD5Z5.0-Q application, or PESD5Z5.0-Q equivalent, key selection criteria include unidirectional clamping behavior, sub-100 pF capacitance for signal integrity, AEC-Q101 qualification for automotive use, and SOD523 footprint compatibility with space-constrained PCB layouts.
Technical Context
This device operates as a unidirectional transient voltage suppressor, conducting only when anode-to-cathode voltage exceeds ~6.2 V breakdown threshold. Its clamping action limits line voltage to ≤18 V during 10 A surge events, with differential resistance of 15 Ω ensuring rapid energy dissipation.
Designed for placement directly at I/O connectors, it relies on minimal PCB trace inductance to achieve effective ESD suppression. The SOD523 package's 1.2 mm × 0.8 mm footprint supports routing of high-speed lines without stubs or impedance discontinuities.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5 V - maximum continuous operating voltage before conduction begins; ensures no interference with 3.3 V or 5 V logic signaling. |
| Breakdown Voltage | 6.2 V (at 1 mA) - precise turn-on threshold enabling early clamping before downstream IC damage occurs. |
| Clamping Voltage | 18 V (at 10 A, 8/20 µs) - peak line voltage under worst-case surge; stays below absolute maximum ratings of most interface transceivers. |
| Diode Capacitance | 89 pF (typical, 1 MHz, 0 V) - low enough to avoid signal degradation on USB 2.0 (480 Mbps) and audio/data lines. |
| ESD Withstand | ±30 kV (IEC 61000-4-2 contact) - exceeds industrial and automotive immunity requirements for human-touch interfaces. |
| Peak Pulse Power | 180 W (non-repetitive, 8/20 µs) - sustains high-energy transients without thermal runaway or parametric shift. |
| Leakage Current | 5 nA (at 5 V, 25 °C) - negligible loading on battery-powered or high-impedance sensor inputs. |
Pinout & Package
SOD523 (SC-79) ultra-small surface-mount plastic package: 1.2 mm × 0.8 mm × 0.6 mm body, flat lead, cathode band marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to system ground or protected line return path; defines polarity for unidirectional clamping. |
| 2 | Anode (A) | Connected to signal line requiring protection; conducts transient current toward ground when voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HBM ESD, and high-temp operating life. |
| Low clamping voltage | 12 V typical at 5 A enables protection of 3.3 V I/O pins without violating absolute maximum ratings. |
| Sub-100 pF capacitance | 89 pF typical preserves signal rise time and eye diagram integrity on 480 Mbps USB 2.0 and audio data lines. |
| Ultra-compact SOD523 | 1.2 mm × 0.8 mm footprint saves board area in mobile and wearables where connector-side real estate is constrained. |
Applications
| USB 2.0 Data Lines | HDMI Hot-Plug Detection |
|---|---|
|
Use Scenario: Protecting D+ and D− lines in portable USB peripherals against user-hand ESD events. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed within 2 mm of USB connector to limit transient voltage to ≤18 V.

IC Role / Device Role / Timing Role: AEC-Q101-qualified transient suppressor mounted adjacent to RCA or FAKRA connectors. Use Value: Maintains signal-to-noise ratio by limiting clamping noise injection and surviving 150 °C junction temperature operation. |
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 ESD5Z5.0T1G | Same SOD523 package, 5 V VRWM, but higher typical capacitance (110 pF) and lower ESD rating (±22 kV). | Limited to non-automotive consumer electronics due to lack of AEC-Q101 qualification. | Select when cost sensitivity outweighs automotive qualification and ultra-low capacitance needs. |
| Vishay ESDE5Z5.0 | Identical electrical specs but uses SC-79 variant with slightly different land pattern; 150 °C Tj max same. | Compatible in footprint but requires verification of solder mask clearance per Vishay drawing 715AB. | Choose for dual-sourcing flexibility where PCB layout allows minor pad tolerance adjustment. |
Compared with ESD5Z5.0T1G and ESDE5Z5.0, the PESD5Z5.0-Q offers superior ESD immunity (±30 kV), tighter capacitance control (89 pF vs. ≥110 pF), and formal AEC-Q101 validation - making it the preferred choice for automotive infotainment and premium mobile interfaces demanding highest reliability.

FAQ
What is the maximum operating temperature for PESD5Z5.0-Q?
The PESD5Z5.0-Q has a maximum junction temperature of 150 °C and a storage temperature range of −65 °C to +150 °C. Its AEC-Q101 qualification confirms stable operation under automotive thermal cycling conditions, including sustained 125 °C ambient with power dissipation.
Can PESD5Z5.0-Q be used for bidirectional signal lines?
No - PESD5Z5.0-Q is strictly unidirectional, with anode (pin 2) and cathode (pin 1) terminals defining conduction only from anode to cathode. For bidirectional protection, a dual-diode configuration or dedicated bidirectional device such as PESD5V0S1BA must be used.
How does its 89 pF capacitance affect USB 2.0 signal integrity?
At 89 pF typical (measured at 1 MHz, 0 V), the device introduces negligible capacitive loading on USB 2.0 D+/D− lines. Eye diagrams remain compliant up to 480 Mbps, with rise/fall time degradation less than 5% when placed within 3 mm of the connector per Nexperia application guidance.
Is PESD5Z5.0-Q compatible with lead-free reflow processes?
Yes - the SOD523 package is rated for standard JEDEC J-STD-020 lead-free reflow profiles, with peak temperatures up to 260 °C. Nexperia specifies a maximum reflow temperature of 260 °C for 30 seconds, matching IPC Class 3 assembly requirements.
