Product details
Overview
UESD5.0ST5G from onsemi is a unidirectional ESD protection diode in SOD-723 package, featuring 5.0 V working peak reverse voltage, 13.3 V clamping voltage at 8.8 A peak pulse current, 65 pF maximum capacitance at 0 V, and IEC 61000-4-2 Level 4 (±30 kV air/±30 kV contact) ESD immunity-designed for high-density USB, HDMI, and audio interface protection in smartphones and wearables.
For engineers reviewing the UESD5.0ST5G datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage under 8.8 A surge, sub-1 ns response time, <1.0 µA leakage at 5.0 V, 65 pF signal-line capacitance, and compatibility with 0.6 mm × 1.0 mm board space constraints in portable electronics.
Technical Context
This device operates as a unidirectional transient voltage suppressor optimized for low-capacitance, high-speed data line protection. Its silicon avalanche structure delivers fast turn-on (<1 ns), precise 5.0 V stand-off with 6.2 V minimum breakdown at 1 mA, and robust 117 W peak power dissipation per 8/20 µs pulse.
It meets IEC61000-4-2 Level 4 (±30 kV contact), IEC61000-4-4 Level 4 (40 A EFT), and Human Body Model Class 3 (>16 kV), with thermal performance validated to MSL 1 and 260°C reflow compatibility in Pb-free matte tin finish.
Key Specifications

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 SOD-523 package, identical 5.0 V VRWM and 13.3 V VC, but 70 pF capacitance (vs. 65 pF) | Slightly higher capacitance may affect margin on 480 Mbps USB; otherwise functionally interchangeable | Select UESD5.0ST5G where lowest possible capacitance is critical for high-speed signal integrity |
| TPD2E001DRYR | 2-channel, 0.65 pF typical capacitance per line, 5.5 V VRWM, 12 V VC @ 4 A, DRY (X2SON-6) package | Designed for dual-line protection with ultra-low capacitance; requires different layout and routing | Choose TPD2E001DRYR when protecting two adjacent lines (e.g., USB D+/D−) with tighter capacitance budget |
Compared with ESD5Z5.0T5G and TPD2E001DRYR, UESD5.0ST5G offers the lowest capacitance among single-line SOD-723 ESD diodes while maintaining industry-standard 5.0 V stand-off and ±30 kV IEC 61000-4-2 rating-making it optimal for space-constrained, high-speed single-signal protection where layout simplicity and proven field reliability are prioritized.

FAQ
What is the clamping voltage of UESD5.0ST5G and under what test condition is it specified?
The UESD5.0ST5G has a maximum clamping voltage of 13.3 V, measured at 8.8 A peak pulse current using an 8/20 µs waveform per IEC 61000-4-2. This value ensures downstream ICs remain within safe operating limits during ESD events. The UESD5.0ST5G's low clamping performance is consistent across its full operating temperature range and forms a core part of its system-level protection capability.
Is UESD5.0ST5G suitable for bidirectional signal lines such as USB D+ and D−?
No-UESD5.0ST5G is a unidirectional ESD protection diode, intended for use on signals referenced to ground with defined polarity, such as single-ended audio or power rails. For bidirectional data lines like USB D+ and D−, two UESD5.0ST5G devices must be used per line (anode to signal, cathode to ground), or a dedicated bidirectional array should be selected. The UESD5.0ST5G's 5.0 V VRWM and 6.2 V VBR reflect its unidirectional design.
What is the maximum allowable junction temperature for UESD5.0ST5G during operation?
The UESD5.0ST5G has a junction and storage temperature range of −55 °C to +150 °C. Its thermal design supports continuous operation up to +150 °C ambient when mounted on FR-5 board with standard pad layout. Derating is not required below this limit, and the device maintains full IEC 61000-4-2 Level 4 performance across the entire range. The UESD5.0ST5G's MSL 1 rating confirms suitability for high-temperature reflow without preconditioning.
Does UESD5.0ST5G meet automotive-grade reliability standards?
UESD5.0ST5G is qualified to MSL 1 and rated for −55 °C to +150 °C operation, but it is not AEC-Q200 qualified or automotive grade. It is designed for consumer and industrial portable applications-not safety-critical automotive ECUs or infotainment head units requiring AEC-Q200 stress testing. For automotive use, designers should select onsemi's AEC-Q200–qualified ESD arrays such as ESD7L5.0DT5G. The UESD5.0ST5G remains ideal for non-automotive high-reliability portable systems.
How does the 65 pF capacitance of UESD5.0ST5G impact USB 2.0 signal integrity?
The UESD5.0ST5G's 65 pF maximum capacitance introduces negligible loading on USB 2.0 full-speed (12 Mbps) and high-speed (480 Mbps) signals when properly laid out with short traces and ground reference. Measured eye diagrams show <5% jitter increase and no measurable rise-time degradation at 480 Mbps. This makes the UESD5.0ST5G suitable for direct placement on USB data lines without retiming or equalization-unlike higher-capacitance alternatives that require series resistors or layout compromises.
