Product details
Overview
SZUESD5.0DT5G from onsemi is a unidirectional ESD protection diode in SOT-723 package, with 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 rating - deployed for high-speed data line protection in USB 2.0 interfaces of smartphones and wearables.
For engineers reviewing the SZUESD5.0DT5G datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage under 12 V at 1 A IPP, sub-0.1 µA leakage at VRWM, AEC-Q101 qualification, and ultra-compact 1.20 mm × 0.80 mm footprint for space-constrained portable designs.
Technical Context
This device operates as a single-channel, cathode-common dual-cathode unidirectional TVS diode - configured with Pins 1 & 2 as cathodes and Pin 3 as anode to provide low-capacitance transient suppression on one signal line referenced to ground. Its clamping behavior is defined by silicon avalanche structure with controlled Zener-like breakdown at 6.2 V.
The SOT-723 package enables direct integration into high-density PCB layouts without compromising thermal performance: MSL 1 rating supports lead-free reflow up to 260 °C, and junction-to-ambient thermal resistance is 525 °C/W on FR-5 board, enabling stable operation across −55 °C to +150 °C ambient 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 protected signal swing. |
| 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-induced overvoltage seen by downstream ICs during ESD events. |
| C (typ) | 38 pF @ 0 V - Low capacitance preserves signal integrity on high-speed lines like USB 2.0 (480 Mbps). |
| IR (max) | 0.1 µA @ VRWM - Minimal leakage avoids DC loading or battery drain in always-on portable circuits. |
| 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 activation prevents transient energy from reaching sensitive transceivers. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Common cathode connection for dual-cathode configuration; tied to protected signal line. |
| 2 | Cathode | Second cathode terminal - electrically identical to Pin 1; enables symmetric layout routing. |
| 3 | Anode | Ground reference node; connects to system GND to complete ESD current path during clamping. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-compact footprint | 1.20 mm × 0.80 mm area - saves >60% board space vs. SOT-23, critical for slim mobile PCBs. |

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 SOT-723 package, 5.0 V VRWM, but 45 pF capacitance and 15 kV HBM rating (vs. 16 kV). | Higher capacitance may impact >200 Mbps interfaces; lower HBM margin reduces margin for extreme handling conditions. | Select when cost sensitivity outweighs marginal capacitance or ESD margin trade-offs. |
| TPD2E001DRYR | 2-channel, 0.65 mm × 0.65 mm DRY package, 5.5 V VRWM, 12 pF, but requires external capacitor for IEC61000-4-2 compliance. | Lower capacitance suits USB 3.0/MIPI, but added BOM complexity and layout area vs. single-device solution. | Select for multi-line protection where board area per line is more critical than part count. |
Compared with ESD5Z5.0T5G and TPD2E001DRYR, SZUESD5.0DT5G delivers optimal balance of ultra-low capacitance (38 pF), highest HBM rating (16 kV), and single-line simplicity in the smallest standardized footprint - making it preferred for high-volume, space-constrained USB 2.0 and sensor interface designs.

FAQ
What is the maximum clamping voltage of SZUESD5.0DT5G at 1 A peak pulse current?
The SZUESD5.0DT5G has a maximum clamping voltage (VC) of less than 12 V when subjected to a 1 A peak pulse current (IPP). This value is measured per IEC61000-4-2 waveform and ensures protected ICs experience minimal overvoltage stress during ESD events. The actual clamping voltage is typically lower under real-world conditions due to the device's fast <1 ns response time and low dynamic impedance.
Does SZUESD5.0DT5G support bidirectional signal lines like USB D+ and D−?
SZUESD5.0DT5G is a unidirectional ESD diode - it protects only signals referenced to ground in one polarity. For full USB 2.0 differential pair protection, two SZUESD5.0DT5G devices are used: one per line (D+, D−), each with its anode grounded. Its dual-cathode pinout (Pins 1 & 2) simplifies layout symmetry without requiring discrete cathode ties.
Is SZUESD5.0DT5G qualified for automotive applications?
Yes, SZUESD5.0DT5G is AEC-Q101 qualified and PPAP capable. It meets stringent automotive reliability requirements including temperature cycling, humidity testing, and mechanical shock - making it suitable for infotainment systems, body control modules, and telematics units where ESD immunity must be guaranteed over vehicle lifetime.
What is the thermal resistance and power derating behavior of SZUESD5.0DT5G?
SZUESD5.0DT5G has a junction-to-ambient thermal resistance (RJA) of 525 °C/W on FR-5 board. Its steady-state power dissipation is rated at 240 mW at 25 °C, derating linearly by 1.9 mW/°C above that temperature. This supports reliable operation up to +150 °C junction temperature, provided PCB copper area and airflow meet minimum layout guidelines in the datasheet.
How does the 38 pF capacitance of SZUESD5.0DT5G affect USB 2.0 signal integrity?
The 38 pF typical capacitance of SZUESD5.0DT5G introduces negligible insertion loss and group delay on USB 2.0 differential pairs - validated via eye diagram testing at 480 Mbps. Unlike higher-capacitance alternatives (>60 pF), this value avoids measurable jitter increase or amplitude reduction, preserving USB-IF compliance without requiring equalization or pre-emphasis in host/device PHYs.
