Product details
Overview
UESD5.0DT5G from onsemi is a unidirectional ESD protection diode in SOT-723 package, featuring 5.0 V working peak reverse voltage (VRWM), 6.2 V minimum breakdown voltage (VBR), 38 pF typical capacitance at 0 V bias, <1 ns response time, and IEC61000-4-2 Level 4 (±30 kV air/±30 kV contact) ESD protection. It safeguards high-speed data lines in space-constrained portable electronics.
For engineers reviewing the UESD5.0DT5G datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage under 12 V at 1 A IPP, low leakage (<0.1 µA at VRWM), AEC-Q101 qualification, and compatibility with 0.4 mm pitch PCB layouts.
Technical Context
This device operates as a single-channel, cathode-common dual-cathode unidirectional TVS diode. Its structure enables bidirectional ESD suppression on a single line using one anode and two cathodes - ideal for I/O line protection where polarity is fixed and board area is constrained.
The SOT-723 package (1.20 × 0.80 × 0.50 mm) supports reflow soldering up to 260 °C and meets MSL 1 requirements. Electrical behavior is characterized by sharp Zener-like breakdown at 6.2 V (min), clamping to ≤12 V at 1 A peak pulse current, and stable leakage below 0.1 µA across −55 °C to +150 °C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 5.0 V - Maximum continuous reverse operating voltage before conduction begins; sets upper limit for signal swing in protected interface |
| VBR (min) | 6.2 V @ 1 mA - Ensures reliable turn-on above normal operating voltage while avoiding false triggering |
| VC @ IPP=1 A | ≤12 V - Clamping voltage limits transient overvoltage seen by downstream ICs during ESD events |
| C (typ) | 38 pF @ 0 V, 1 MHz - Low capacitance preserves signal integrity on USB 2.0, HDMI, or audio lines |
| ESD Rating | ±30 kV air / ±30 kV contact per IEC61000-4-2 Level 4 - Meets industrial and consumer immunity requirements |
| Response Time | <1 ns - Fast enough to suppress ESD transients before sensitive circuitry is damaged |
| Leakage Current | <0.1 µA @ 5.0 V - Minimizes power loss and avoids loading of high-impedance analog or RF nodes |
Pinout & Package
SOT-723 (Case 631AA, Style 4) is a 3-pin ultra-small surface-mount package measuring 1.20 mm × 0.80 mm × 0.50 mm with 0.40 mm lead pitch. Void-free thermosetting plastic body meets UL 94 V-0; matte tin lead finish supports Pb-free assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Common cathode connection for dual-cathode configuration; ties to system ground or low-impedance return path |
| 2 | Cathode | Second cathode terminal - electrically identical to Pin 1; enables compact layout with shared ground routing |
| 3 | Anode | Signal input terminal - connects to protected line (e.g., USB D+, HDMI TMDS+); conducts during negative ESD transients |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-compact footprint | 1.20 mm × 0.80 mm - Saves >60% board area vs. SOT-23, enabling protection on dense mobile PCBs |
| Low clamping voltage | ≤12 V @ 1 A IPP - Limits stress on 5 V-tolerant I/O pins without requiring additional series impedance |
| AEC-Q101 qualified | Qualified for automotive infotainment and ADAS sensor interfaces requiring robust ESD resilience |
| IEC61000-4-4 Level 4 EFT protection | Withstands 40 A fast transient bursts - protects against switching noise in power supply rails and control lines |
| Pb-free & RoHS compliant | 100% matte Sn finish - compatible with lead-free reflow profiles and global environmental regulations |
Applications
| USB 2.0 Data Lines | HDMI Interface Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| UESD5.0D3T5G | Same electrical specs but in SOT-323 (2.1 × 1.3 × 0.95 mm); 2× larger footprint, higher thermal mass | Better power handling margin for high-repetition EFT events; less suitable for ultra-thin devices | Select when board space permits and higher steady-state power derating (525 mW vs. 240 mW) is needed |
| TPD2E001DRYR | 2-channel unidirectional; 5.5 V VRWM; 12 pF capacitance; no AEC-Q101 qualification | Lower capacitance benefits USB 3.0/MIPI D-PHY; lacks automotive qualification and IEC61000-4-4 rating | Select for high-speed digital interfaces where capacitance is critical and automotive compliance is not required |
Compared with UESD5.0D3T5G and TPD2E001DRYR, the UESD5.0DT5G uniquely balances ultra-small size, automotive qualification, and full IEC61000-4-2/4-4 compliance - making it optimal for space-limited, safety-conscious portable and automotive applications where both form factor and certification matter.

FAQ
What is the maximum clamping voltage of UESD5.0DT5G under ESD stress?
The UESD5.0DT5G clamps to ≤12 V at 1 A peak pulse current (IPP), as specified in its electrical characteristics table. This value represents the maximum voltage imposed on the protected line during standardized 8/20 µs surge events. The clamping performance is validated per IEC61000-4-2 testing conditions and remains consistent across the full operating temperature range of −55 °C to +150 °C. Designers should reference this VC value when verifying margin against the absolute maximum ratings of downstream ICs.
Is UESD5.0DT5G suitable for protecting bidirectional data lines like I²C?
No - UESD5.0DT5G is a unidirectional ESD diode optimized for single-polarity signal paths such as USB D+ or HDMI TMDS+. For bidirectional interfaces like I²C, a bidirectional ESD suppressor (e.g., UESD5.0D3T5G or NUP4105MR6T1G) is required to handle both positive and negative transients. Using UESD5.0DT5G on I²C would leave the line unprotected during negative excursions beyond VRWM, risking latch-up or damage to pull-up networks.
Does UESD5.0DT5G require external series resistance for USB 2.0 protection?
No - UESD5.0DT5G is designed for direct placement on USB 2.0 data lines without added series impedance. Its 38 pF capacitance and ≤12 V clamping voltage meet USB 2.0 eye diagram and signal integrity requirements when placed within 5 mm of the connector. External resistors are unnecessary unless specific system-level overshoot analysis indicates marginal timing margins - in which case layout optimization is preferred over adding lossy components.
What is the thermal resistance (RJA) of UESD5.0DT5G on FR-5 board?
The UESD5.0DT5G has a thermal resistance of 525 °C/W from junction to ambient on a standard FR-5 test board (1.0 × 0.75 × 0.62 in). This value reflects its ability to dissipate transient energy without exceeding the 150 °C maximum junction temperature. Derating begins above 25 °C at 1.9 mW/°C, limiting usable power dissipation to 240 mW at room temperature. Layout enhancements (e.g., thermal vias, copper pour) can improve actual RJA in production designs.
Can UESD5.0DT5G be used in place of UESD3.3DT5G in a 3.3 V system?
No - UESD5.0DT5G has a 5.0 V working peak reverse voltage (VRWM), making it unsuitable for direct replacement of UESD3.3DT5G in 3.3 V systems. At 3.3 V operation, UESD5.0DT5G's higher VRWM increases risk of insufficient margin against normal signal overshoot, potentially allowing damaging transients to pass unclamped. The UESD3.3DT5G (VRWM = 3.3 V) provides tighter voltage alignment and lower clamping onset for 3.3 V logic domains.
