Product details
Overview
PESD5Z3.3 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), IEC 61000-4-5 surge (20 A), with 3.3 V reverse standoff voltage, 172 pF typical capacitance, and 8 V clamping voltage at 5 A.
For engineers reviewing the PESD5Z3.3 datasheet, PESD5Z3.3 pinout, PESD5Z3.3 application, or PESD5Z3.3 equivalent, this device is selected for high-speed data line protection where low capacitance, fast transient response, and minimal signal distortion are critical-especially in USB 2.0, HDMI, SIM card interfaces, and Ethernet PHY front-ends.
Technical Context
This unidirectional TVS diode operates as a clamping device in series with a signal path referenced to ground, conducting only when forward-biased during negative transients or reverse-biased beyond breakdown (5 V typ). Its low differential resistance (10 Ω) ensures rapid voltage suppression during 8/20 µs surges up to 20 A.
It exhibits stable performance across –65 °C to +150 °C ambient, with reverse leakage held to ≤50 nA at 3.3 V and junction temperature-dependent capacitance (172–200 pF at 0 V, 1 MHz), making it suitable for signal integrity–sensitive applications without requiring biasing circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 3.3 V - Maximum continuous operating voltage before conduction; sets upper limit for protected line DC bias. |
| Clamping Voltage | 8 V @ 5 A - Peak voltage seen by downstream IC during ESD event; ensures safe margin below IC absolute max ratings. |
| Diode Capacitance | 172 pF @ 0 V, 1 MHz - Low enough for <1 Gbps signal integrity preservation on USB 2.0 or LVDS lines. |
| ESD Rating | ±30 kV IEC 61000-4-2 contact - Validated immunity level for handheld device interface ports. |
| Peak Pulse Current | 20 A @ 8/20 µs - Withstands IEC 61000-4-5 surge events on industrial or telecom data lines. |
| Leakage Current | 8 nA @ 3.3 V - Negligible loading on battery-powered sensor or SIM card detection circuits. |
| Breakdown Voltage | 5 V @ 1 mA - Confirmed turn-on threshold ensuring reliable clamping before system damage occurs. |
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 ground or low-impedance return path; carries surge current during positive transients on protected line. |
| 2 | Anode (A) | Connected to signal line under protection; conducts during negative ESD events relative to ground. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional clamping architecture | Enables polarity-specific protection on single-ended lines without affecting DC bias or causing false triggering on normal signal swings. |
| Low 172 pF capacitance | Maintains signal rise/fall time integrity on 480 Mbps USB 2.0 or 100BASE-TX Ethernet traces without measurable eye diagram degradation. |
| 8 V clamping at 5 A | Provides ≥1.5 V safety margin below typical 9.5 V absolute maximum rating of USB transceivers and audio codec I/O pins. |
| 30 kV IEC 61000-4-2 ESD immunity | Meets highest consumer-grade ESD robustness requirement for exposed connectors in smartphones and docking stations. |
| 260 W peak pulse power | Supports multi-pulse surge resilience in industrial control I/O modules subjected to repeated lightning-induced transients. |
Applications
| USB 2.0 Data Lines | SIM Card Interfaces |
|---|---|
Use Scenario: Protection of D+ and D− lines in smartphone USB OTG ports exposed to frequent plug/unplug and human-hand ESD. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed between connector and USB transceiver, shunting ESD energy to ground before reaching PHY input pins. Use Value: Prevents latch-up or gate oxide damage in USB PHY while preserving 480 Mbps eye diagram compliance per USB-IF test plan. | Use Scenario: ESD safeguard for SIM card slot VCC, I/O, and CLK lines in mobile handsets and IoT modules. IC Role / Device Role / Timing Role: Single-line protector on each SIM signal, mounted adjacent to card connector to minimize transient loop inductance. Use Value: Ensures SIM detection reliability and prevents false card removal interrupts caused by ±8 kV contact discharge events. |
| 10/100/1000BASE-T Ethernet PHY | Audio Line Inputs (3.5 mm Jack) |
Use Scenario: Front-end protection of MDI differential pairs in enterprise switch PHYs handling PoE and external cabling. IC Role / Device Role / Timing Role: One PESD5Z3.3 per line (TX+/TX−/RX+/RX−), grounded cathode configuration, placed before common-mode choke. Use Value: Limits induced surge voltage to <10 V during IEC 61000-4-5 20 A tests, avoiding PHY receiver saturation or internal LDO overvoltage. | Use Scenario: Input protection for analog audio line-in jacks on laptops and portable speakers subject to user-hand static discharge. IC Role / Device Role / Timing Role: Clamping diode between tip/ring and ground, leveraging low capacitance to avoid high-frequency roll-off above 20 kHz. Use Value: Maintains full audio bandwidth (20 Hz–20 kHz) while suppressing ±15 kV ESD pulses that would otherwise trigger ADC input latch-up. |
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 array; 12 pF capacitance; 5.5 V standoff; 12 V clamping @ 5 A | Designed for multi-line protection (e.g., HDMI); lower capacitance but higher clamping voltage | Select when protecting ≥2 lines simultaneously and signal bandwidth exceeds 3 GHz; not suitable for single-line cost-sensitive designs. |
| Vishay ESDBLE5.0D1W | Bi-directional; 12 pF capacitance; 5 V standoff; 12.5 V clamping @ 5 A | Protects AC-coupled or bipolar signal lines (e.g., audio differential pairs); no polarity dependency | Choose for symmetrical signal paths where polarity reversal occurs; avoid for DC-biased unidirectional lines like SIM VCC. |
Compared with NUP4105MR6T1G and ESDBLE5.0D1W, PESD5Z3.3 offers optimal trade-off for single-line, DC-biased, high-speed applications: lowest cost per line, verified 30 kV ESD rating, and precise 3.3 V standoff matching modern low-voltage I/O rails-without over-engineering capacitance or clamping.

FAQ
What is the maximum operating temperature for PESD5Z3.3?
The PESD5Z3.3 supports junction temperatures up to +150 °C and ambient storage/operation from –65 °C to +150 °C, validated per IEC 60134 limiting values. This enables use in under-hood automotive infotainment interfaces and industrial motor drive control panels with localized thermal hotspots.
Can PESD5Z3.3 be used on bidirectional signal lines like I²C?
No-PESD5Z3.3 is unidirectional and conducts only when anode is negative relative to cathode. For bidirectional buses such as I²C or UART, a bi-directional ESD diode (e.g., PESD5V0S1BA) is required to clamp both positive and negative transients without disrupting DC bias.
How does the 172 pF capacitance affect USB 2.0 signal integrity?
At 172 pF, PESD5Z3.3 introduces <0.5 dB insertion loss at 480 MHz and preserves >85% eye height in USB 2.0 compliance testing. Layout best practices-placing the device within 3 mm of the connector and using short, direct traces-ensure minimal impact on rise time and jitter.
Is PESD5Z3.3 automotive qualified?
No-this device is not AEC-Q200 qualified or tested for automotive temperature cycling, humidity, or vibration stress. It is intended for commercial and industrial applications. For automotive infotainment or ADAS camera links, select Nexperia's automotive-grade equivalents such as PESD5Z3.3AUK.
