Product details
Overview
PESD5Z7.0-Q 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). It delivers 7 V reverse standoff voltage, 19 V clamping at 10 A, and 69 pF typical capacitance at 1 MHz - enabling use on high-speed data lines such as USB 2.0 and Ethernet PHY interfaces.
For engineers reviewing the PESD5Z7.0-Q datasheet, PESD5Z7.0-Q pinout, PESD5Z7.0-Q application, or PESD5Z7.0-Q equivalent, key selection criteria include its automotive-qualified AEC-Q101 status, ultra-low leakage (<1 nA at 7 V), and sub-15 Ω differential resistance - critical for preserving signal integrity in compact portable electronics and automotive infotainment interfaces.
Technical Context
This unidirectional TVS diode operates as a clamping device with a breakdown voltage of 7.5 V (at 1 mA), triggering conduction above VRWM = 7 V to divert transient energy to ground. Its cathode-anode polarity defines strict unidirectional protection for signals referenced to ground with fixed polarity.
The device uses silicon PN-junction technology optimized for fast response (<1 ns) to ESD events and low parasitic capacitance. Its thermal design supports junction temperatures up to 150 °C, and its peak pulse power rating of 180 W (8/20 µs) ensures robustness against repetitive surge stress in automotive and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 7 V - maximum continuous operating voltage before clamping begins; sets safe margin for 5 V or 3.3 V signal rails. |
| Clamping Voltage | 19 V at 10 A (8/20 µs) - limits transient voltage seen by downstream ICs during surge events. |
| Diode Capacitance | 69 pF typical at 1 MHz, 0 V - enables use on high-speed lines (e.g., USB 2.0, HDMI DDC) without signal degradation. |
| ESD Rating | ±30 kV per IEC 61000-4-2 contact discharge - exceeds Level 4 immunity requirements for consumer and automotive end equipment. |
| Peak Pulse Current | 10 A (8/20 µs waveform) - withstands surge transients per IEC 61000-4-5, suitable for Ethernet and telecom line protection. |
| Leakage Current | <1 nA at 7 V - minimizes DC loading on sensitive analog or reference signal paths. |
| Differential Resistance | 15 Ω - determines voltage rise under transient current; lower value improves clamping efficiency. |
Pinout & Package
SOD523 (SC-79) surface-mount plastic package: 2-terminal, ultra-compact footprint (1.2 mm × 0.8 mm × 0.6 mm), flat lead, cathode band marked on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to system ground or protected line return path; defines unidirectional conduction direction. |
| 2 | Anode (A) | Connected to signal line requiring protection; conducts transient current toward cathode when voltage exceeds VRWM. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Qualified for automotive applications including infotainment, ADAS sensors, and body control modules. |
| Low clamping voltage | 19 V at 10 A ensures downstream ICs (e.g., USB transceivers, Ethernet PHYs) remain within absolute maximum ratings during surge. |
| Ultra-low leakage | <1 nA at 7 V prevents signal drift or bias error in precision analog front-ends and SIM card interfaces. |
| Small-footprint SOD523 | Enables placement directly at board edge connectors - minimizing PCB trace inductance and improving ESD suppression efficacy. |
| High ESD immunity | 30 kV contact discharge meets stringent IEC 61000-4-2 Level 4, supporting CE/FCC compliance for handheld and portable devices. |
Applications
| USB 2.0 Data Lines | Ethernet PHY Interfaces |
|---|---|
|
Use Scenario: Protection of D+ and D− lines in USB 2.0 host/device ports against ESD during cable insertion or handling. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed between signal line and ground, triggered only during positive transients relative to GND. Use Value: 69 pF capacitance avoids signal rise-time degradation; 19 V clamping prevents damage to USB transceiver I/O cells rated for 3.6 V max. |
Use Scenario: Surge protection on 10/100/1000 Mbit/s Ethernet differential pairs (e.g., TX+/TX−, RX+/RX−) at RJ45 connector entry point. IC Role / Device Role / Timing Role: Per-line unidirectional TVS, one device per signal, grounded cathode configuration for common-mode transient suppression. Use Value: 10 A surge rating handles IEC 61000-4-5 induced surges; AEC-Q101 qualification supports automotive Ethernet gateways and telematics units. |
| SIM Card Interfaces | Automotive Infotainment Displays |
|
Use Scenario: ESD protection for SIM card data (I/O), clock (CLK), and reset (RST) pins in smartphones and tablets. IC Role / Device Role / Timing Role: Single-line unidirectional protector per signal, with anode tied to signal and cathode to ground. Use Value: Sub-1 nA leakage preserves low-power sleep states; small SOD523 footprint fits tight space constraints near SIM socket. |
Use Scenario: Signal line protection for LVDS or FPD-Link video interfaces between head unit MCU and display module in vehicles. IC Role / Device Role / Timing Role: High-speed ESD clamp on unidirectional control/data lines (e.g., backlight enable, touch interrupt) exposed to user-accessible zones. Use Value: AEC-Q101 qualification ensures reliability across -40 °C to +125 °C ambient; 30 kV ESD rating covers service technician handling risks. |
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 | Quad-channel, 5.5 V VRWM, 12 V clamping at 1 A; higher capacitance (120 pF typical). | Designed for multi-line protection; less suitable for single-line ultra-high-speed applications due to higher capacitance. | Select when protecting multiple lines simultaneously on space-constrained boards where shared ground layout is acceptable. |
| Vishay ESDE05C1-2 | Unidirectional, 5 V VRWM, 12 V clamping at 5 A; 30 pF capacitance; no AEC-Q101 qualification. | Lower clamping and capacitance benefit high-speed interfaces, but lacks automotive qualification and 30 kV ESD rating. | Prefer for consumer-grade USB or audio interfaces where cost and speed outweigh automotive reliability requirements. |
Compared with NUP4105MR6T1G and ESDE05C1-2, PESD5Z7.0-Q uniquely balances automotive qualification, 30 kV ESD immunity, and 69 pF capacitance - making it optimal for single-line protection in safety-critical, high-reliability automotive and industrial designs where both speed and ruggedness are mandatory.

FAQ
Is PESD5Z7.0-Q suitable for bidirectional signal lines?
No. PESD5Z7.0-Q is strictly unidirectional, with cathode (pin 1) tied to ground and anode (pin 2) connected to the protected line. It conducts only when the signal goes positive relative to ground. For bidirectional lines like USB D+/D− differential pairs, two devices (one per polarity) or a dedicated bidirectional variant such as PESD5V0S1BA must be used.
What is the maximum recommended PCB trace length between PESD5Z7.0-Q and the protected connector?
Trace length should not exceed 3 mm from the device cathode to the nearest ground via, and the anode-to-connector distance should be minimized - ideally ≤2 mm. Longer traces increase inductance, degrading clamping performance during fast ESD events; layout guidelines in the datasheet emphasize direct routing and adjacent ground vias.
Does PESD5Z7.0-Q require external series impedance for optimal ESD protection?
No external resistor is required for basic ESD clamping, but a small series resistor (e.g., 0–10 Ω) may be added between the protected IC and the diode to limit peak current during clamping. The device's 15 Ω differential resistance and low capacitance allow direct placement without compromising signal integrity on lines up to 480 Mbps.
How does PESD5Z7.0-Q perform under repeated ESD stress?
Tested per IEC 61000-4-2 with ten non-repetitive ±30 kV contact discharges, PESD5Z7.0-Q maintains electrical parameters within specification. Its silicon junction design and 180 W peak pulse power rating ensure stable performance across multiple ESD events without parameter shift or failure - validated in AEC-Q101 stress testing.
