Product details
Overview
SZESD5Z2.5T5G from onsemi is a unidirectional ESD protection diode in SOD-523 package, featuring 2.5 V working peak reverse voltage (VRWM), 6.5 V clamping voltage at 5 A (VC), <1 ns response time, and IEC 61000-4-2 Level 4 (±30 kV contact) compliance - deployed for USB data line and low-voltage I/O port protection in portable consumer electronics.
For engineers reviewing the SZESD5Z2.5T5G datasheet, pinout, applications, or equivalent options, key selection criteria include clamping performance under 5 A IEC 61000-4-2 surge, sub-1 ns transient response, 1.20 mm × 0.80 mm footprint constraint, and automotive-grade AEC-Q101 qualification for harsh-environment signal-line protection.
Technical Context
This device operates as a unidirectional TVS diode with cathode-anode polarity, designed to clamp transients before they reach downstream ICs. Its low 2.5 V VRWM enables use on 1.8 V and 2.5 V logic rails, while 6.5 V VC at 5 A ensures safe voltage limiting during ESD events per IEC 61000-4-2.
The SOD-523 package supports high-density PCB layouts with 0.7 mm body height and MSL 1 reflow compatibility up to 260 °C. It delivers 120 W peak power dissipation (8/20 µs pulse), 145 pF capacitance, and <100 nA leakage at VRWM - balancing low capacitance and robust ESD immunity for high-speed interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 2.5 V - sets maximum continuous operating voltage on protected line without leakage activation |
| VC @ IPP = 5 A | 6.5 V - clamping voltage during IEC 61000-4-2 8 kV contact discharge, limiting stress on downstream ICs |
| Response Time | <1 ns - ensures conduction before transient propagates into sensitive circuitry |
| Capacitance | 145 pF @ 0 V, 1 MHz - compatible with USB 2.0 and low-speed serial interfaces without signal integrity loss |
| ESD Rating | ±30 kV contact per IEC 61000-4-2 Level 4 - exceeds industrial and automotive system-level ESD requirements |
| Leakage Current | <6.0 µA @ VRWM - avoids DC loading on low-power sensor or battery-backed I/O lines |
| AEC-Q101 Qualified | Yes - validated for automotive infotainment, ADAS camera links, and body control modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5Z2.5T1G | Same electrical specs and SOD-523 package; differs only in tape-and-reel quantity (3000 vs. 8000 units) | No functional difference; suitable for lower-volume prototyping or small-batch production | Select when smaller reel size aligns with assembly line feeder constraints or inventory turnover goals |
| TPD2E001DRYR | Bi-directional, 12 pF capacitance, 5.5 V VRWM, 12 V clamping at 1 A - lower capacitance but higher clamping voltage | Better for high-speed USB 3.0 or HDMI; less effective for sub-3 V rail protection due to higher VRWM | Choose for ultra-low-capacitance needs where 2.5 V rail compatibility is not required |
Compared with ESD5Z2.5T1G and TPD2E001DRYR, SZESD5Z2.5T5G offers identical protection performance to the former in an 8000-unit reel, and provides superior low-voltage rail compatibility versus the latter - critical for 1.8 V I/O protection where 5.5 V VRWM would cause premature conduction.

FAQ
What is the clamping voltage of SZESD5Z2.5T5G under IEC 61000-4-2 8 kV contact discharge?
The SZESD5Z2.5T5G exhibits a clamping voltage of 6.5 V at 5 A peak pulse current (IPP), measured per the IEC 61000-4-2 waveform. This value is confirmed in the Electrical Characteristics table on page 3 of the official onsemi datasheet (Rev. 16, February 2024) and ensures safe voltage limiting for 1.8 V and 2.5 V logic interfaces during ESD events.
Is SZESD5Z2.5T5G qualified for automotive applications?
Yes, SZESD5Z2.5T5G is AEC-Q101 qualified and PPAP capable, as explicitly stated in the datasheet's Specification Features section. The "SZ" prefix denotes automotive-grade manufacturing controls, making SZESD5Z2.5T5G suitable for use in automotive camera modules, infotainment interfaces, and body electronics where ESD robustness and process traceability are mandatory.
What is the package type and dimensions of SZESD5Z2.5T5G?
SZESD5Z2.5T5G uses the SOD-523 package (Case 502), with exact dimensions of 1.20 mm × 0.80 mm × 0.60 mm and a 0.7 mm body height. The mechanical outline drawing on page 5 of the datasheet confirms these measurements, and the device meets MSL 1 moisture sensitivity level with 260 °C reflow capability.
How does the capacitance of SZESD5Z2.5T5G affect high-speed signal lines?
SZESD5Z2.5T5G has a maximum capacitance of 145 pF at 0 V and 1 MHz, which is appropriate for USB 2.0 (480 Mbps), I²C, and UART interfaces but not recommended for USB 3.0 or HDMI. This value balances ESD robustness and signal integrity - verified by onsemi's application note AND8308/D - ensuring minimal rise-time degradation on moderate-speed digital lines.
What is the difference between SZESD5Z2.5T5G and ESD5Z2.5T1G?
SZESD5Z2.5T5G and ESD5Z2.5T1G share identical electrical specifications, thermal ratings, and SOD-523 packaging. The only differences are the "SZ" prefix (indicating automotive-grade process controls and PPAP capability) and tape-and-reel quantity: SZESD5Z2.5T5G ships in 8000-unit reels, while ESD5Z2.5T1G ships in 3000-unit reels - both are Pb-free and RoHS compliant.
