Product details
Overview
ESD5Z5.0T1 from onsemi is a unidirectional ESD protection diode in SOD-523 package, featuring 5.0 V working peak reverse voltage (VRWM), 11.6 V clamping voltage at 5 A (VC), 80 pF capacitance at 0 V, <1 ns response time, and IEC 61000-4-2 Level 4 (±8 kV contact) compliance. It protects high-speed data lines in space-constrained portable electronics.
For engineers reviewing the ESD5Z5.0T1 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping performance under IEC 61000-4-2 surge, low capacitance for USB/MIPI signal integrity, and SOD-523 footprint compatibility with tight-pitch PCB layouts.
Technical Context
This device operates as a unidirectional transient voltage suppressor, leveraging silicon avalanche breakdown to clamp ESD transients before they reach downstream ICs. Its cathode-anode polarity enables integration into DC-biased signal paths such as USB D+/D− or HDMI hot-swap lines.
Designed for board-level ESD hardening, it delivers 174 W peak power dissipation (8 × 20 µs pulse), supports ≤16 kV HBM ESD rating, and maintains ≤0.05 µA reverse leakage at VRWM - critical for battery-powered sensor interfaces and always-on wake-up circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 5.0 V - Maximum continuous reverse voltage before leakage exceeds 0.05 µA; sets upper limit for protected line's DC bias. |
| VC @ IPP = 5 A | 11.6 V - Clamped voltage during 8/20 µs surge; ensures downstream ICs see <12 V stress during ±8 kV IEC contact discharge. |
| C @ 0 V, 1 MHz | 80 pF - Capacitance across diode terminals; low enough to avoid signal degradation on 480 Mbps USB 2.0 lines. |
| Response Time | <1 ns - Time from transient onset to conduction; fast enough to protect sub-nanosecond edge-rate digital interfaces. |
| ESD Rating | Class 3 HBM (>16 kV) - Validated per JESD22-A114; withstands repeated human-body discharges without parametric shift. |
| Package | SOD-523 (1.20 × 0.80 × 0.60 mm) - Enables placement adjacent to connectors on ultra-thin mobile PCBs with 0.65 mm pitch. |
Pinout & Package
SOD-523 surface-mount package with molded thermosetting plastic body (UL 94 V-0), matte tin lead finish, MSL 1 rating, and 260 °C max reflow tolerance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Protected Line Input | Connected to I/O trace requiring ESD suppression; reverse-biased during normal operation. |
| 2 (Anode) | GND Reference | Tied directly to low-inductance system ground plane to minimize clamping loop inductance. |
Key Features
| Feature | Design Value |
|---|---|
| Low Clamping Voltage | 11.6 V at 5 A ensures sensitive 3.3 V or 5 V logic inputs remain within safe operating area during ESD events. |
| Ultra-Small Footprint | 1.20 mm × 0.80 mm SOD-523 saves >60% board area vs. SOT-23, enabling protection at USB-C connector pins. |
| IEC 61000-4-2 Level 4 Compliance | ±8 kV contact / ±15 kV air discharge rating meets industrial and consumer end-equipment certification requirements. |
| Low Capacitance | 80 pF minimizes insertion loss and jitter on high-speed serial links up to 480 Mbps without equalization. |
Applications
| USB 2.0 Data Lines | HDMI Hot-Plug Detection |
|---|---|
Use Scenario: Protecting D+ and D− lines of USB 2.0 peripherals against ESD during cable insertion/removal. IC Role / Device Role / Timing Role: Unidirectional shunt clamp placed between signal line and GND, activated only during positive transients relative to GND. Use Value: 80 pF capacitance avoids signal rise-time degradation; 11.6 V clamping prevents damage to USB PHY transceivers rated for 3.6 V absolute maximum. | Use Scenario: Safeguarding HDMI HPD (Hot-Plug Detect) pin from user-induced ESD when plugging/unplugging displays. IC Role / Device Role / Timing Role: DC-coupled ESD clamp on 5 V-tolerant HPD line, maintaining logic-high state while suppressing transients. Use Value: 5.0 V VRWM matches HDMI HPD's 5 V pull-up; low leakage (<0.05 µA) avoids false low-state detection during idle. |
| Smartphone Camera Interface | Industrial Sensor Node I/O |
Use Scenario: Shielding MIPI CSI-2 clock and data lanes in compact camera modules from handling ESD. IC Role / Device Role / Timing Role: Bidirectional protection not applicable; unidirectional ESD5Z5.0T1 used on DC-biased clock lines referenced to 1.8 V or 2.8 V rails. Use Value: Sub-1 ns response preserves 1 GHz+ clock edge fidelity; SOD-523 size allows placement within 2 mm of image sensor bond pads. | Use Scenario: Hardening analog input pins (e.g., 4–20 mA loop receivers) in factory-floor sensors exposed to maintenance personnel ESD. IC Role / Device Role / Timing Role: Standoff protector on signal conditioning front-end, absorbing transients before op-amp input stages. Use Value: 16 kV HBM rating exceeds IEC 61000-4-2 Level 4; 0.05 µA leakage prevents offset error in precision current measurement. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5Z5.0T5G | Same electrical specs; differs only in tape-and-reel quantity (8000 vs. 3000 units). | No functional difference; identical placement, soldering, and protection behavior on PCB. | Select ESD5Z5.0T5G for high-volume automated assembly where larger reels reduce changeover frequency. |
| TPD2E001DRYR | Bi-directional, 12 pF capacitance, 12 V clamping at 1 A; smaller 0.65 × 0.65 mm X2SON package. | Better suited for differential pairs (e.g., USB D+/D− together); lower capacitance but higher clamping voltage. | Choose TPD2E001DRYR when protecting matched high-speed differential signals where capacitance budget is tighter than voltage margin. |
Compared with ESD5Z5.0T1, ESD5Z5.0T5G offers identical protection performance with optimized logistics packaging, while TPD2E001DRYR trades unidirectionality and higher clamping for ultra-low capacitance and dual-line integration - making each suitable for distinct layout and signal integrity constraints.

FAQ
What is the maximum working voltage for ESD5Z5.0T1?
The ESD5Z5.0T1 has a working peak reverse voltage (VRWM) of 5.0 V, meaning it can safely block up to 5.0 V DC or steady-state reverse bias without significant leakage. This makes it suitable for protecting 3.3 V and 5 V logic lines where the nominal rail voltage does not exceed its standoff rating. Exceeding VRWM risks increased leakage or premature conduction during normal operation.
Does ESD5Z5.0T1 meet IEC 61000-4-2 Level 4 requirements?
Yes, the ESD5Z5.0T1 is rated for IEC 61000-4-2 Level 4 ESD protection: ±8 kV contact discharge and ±15 kV air discharge. This is verified per onsemi's test methodology using oscilloscope waveform capture of clamping behavior during standardized ESD pulses. The device's 11.6 V clamping voltage at 5 A ensures downstream circuitry remains within safe voltage limits during full-level testing.
What is the capacitance of ESD5Z5.0T1 and why does it matter?
The ESD5Z5.0T1 exhibits 80 pF capacitance at 0 V and 1 MHz. This value directly impacts high-speed signal integrity: lower capacitance reduces loading, preserves edge rates, and minimizes jitter. At 80 pF, it supports USB 2.0 (480 Mbps) and MIPI CSI-2 clock lines without requiring signal compensation, unlike higher-capacitance alternatives that may degrade eye diagrams.
Is ESD5Z5.0T1 unidirectional or bidirectional?
The ESD5Z5.0T1 is a unidirectional ESD protection diode, configured with cathode and anode terminals for use on DC-biased lines. Its polarity requires the cathode to connect to the protected signal and the anode to ground. It conducts only during positive transients relative to ground - ideal for single-ended I/O like USB D+, HDMI HPD, or analog sensor outputs referenced to a fixed supply.
What package type does ESD5Z5.0T1 use and what are its dimensions?
The ESD5Z5.0T1 uses the SOD-523 package (case 502), measuring 1.20 mm × 0.80 mm × 0.60 mm with a 0.65 mm pin pitch. Its ultra-compact size and low profile (0.7 mm height) enable placement directly at connectors or IC pads in slim-profile devices like smartphones and wearables, minimizing transient loop inductance and improving protection efficacy.
