Product details
Overview
D5V0H2U3SO from Diodes Incorporated is a dual-channel unidirectional ESD protection diode designed for data line and interface port protection in portable electronics and communication systems. It features 6.4V minimum breakdown voltage, 15A peak pulse current (8/20µs), 156pF typical channel capacitance, ±30kV IEC 61000-4-2 contact/air ESD rating, and clamps to ≤9.8V at 1A transient current.
For engineers reviewing the D5V0H2U3SO datasheet, D5V0H2U3SO pinout, D5V0H2U3SO application, or D5V0H2U3SO equivalent, key selection criteria include low clamping voltage under 1A/15A transients, ultra-low leakage (<1 µA @ 5V), bidirectional capability via pin-1-to-pin-2 configuration, and SOT23 footprint compatibility with high-density PCB layouts.
Technical Context
The D5V0H2U3SO implements two independent unidirectional TVS structures in a single SOT23-3 package, each configured as an anode-to-rail clamp for positive transients and cathode-to-ground clamp for negative transients. Its 6.4V VBR ensures robust margin above 5V logic supply rails while maintaining fast response to sub-nanosecond ESD events.
It operates within –55°C to +125°C junction temperature range and delivers 300W peak pulse power per channel under standardized 8/20µs waveform. The 156pF input capacitance is optimized for USB 2.0 and I²C signal integrity, with <1 µA reverse leakage preserving battery life in always-on portable applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min) | 6.4V - Ensures reliable triggering above 5V system rails without false clamping during normal operation |
| IPP (max) | 15A - Withstands severe 8/20µs surge events per IEC 61000-4-5 Level 3 compliance |
| CT (typ) | 156pF - Maintains signal integrity on 480Mbps USB 2.0 and 1MHz I²C buses |
| VCL @ 1A | ≤9.8V - Limits downstream IC stress during low-energy ESD strikes |
| VESD | ±30kV - Fully satisfies IEC 61000-4-2 Level 4 for both contact and air discharge |
| IRM | <1 µA @ 5V - Minimizes standby current drain in battery-powered devices |
Pinout & Package
Package: SOT23-3, surface-mount, lead-free, halogen-free, moisture sensitivity level 1 (J-STD-020).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Channel 1 | Connects to protected data line (e.g., USB D+); clamps positive transients to VCC |
| Pin 2 | Cathode of Channel 1 / Anode of Channel 2 | Shared node enabling bidirectional operation when tied to Pin 1; otherwise serves as common rail reference |
| Pin 3 | Cathode of Channel 2 | Connects to ground; clamps negative transients to ~–0.7V |
Key Features
| Feature | Design Value |
|---|---|
| Dual unidirectional ESD protection | Two independent 300W channels in one SOT23-3 footprint, reducing board space vs. discrete solutions |
| IEC 61000-4-2 Level 4 compliance | ±30kV contact/air rating enables drop-in use in CE/FCC-certified consumer and industrial end equipment |
| Ultra-low leakage current | <1 µA @ 5V reverse bias preserves battery runtime in always-connected IoT sensors and wearables |
| Low clamping voltage | ≤9.8V @ 1A ensures protected ICs (e.g., USB transceivers) remain within absolute maximum ratings during ESD events |
Applications
| USB 2.0 Port Protection | I²C Bus Protection |
|---|---|
Use Scenario: Protecting host/device USB 2.0 D+/D− lines against user-handling ESD in smartphones, tablets, and docking stations. IC Role / Device Role / Timing Role: Unidirectional clamping diode array placed between connector and PHY IC to limit transient overvoltage. Use Value: 156pF capacitance avoids signal rise-time degradation; ≤9.8V clamping prevents PHY latch-up or damage. | Use Scenario: Safeguarding I²C SDA/SCL lines in embedded microcontroller peripherals such as EEPROMs, sensors, and PMICs. IC Role / Device Role / Timing Role: Low-capacitance ESD shunt placed at bus entry point to suppress contact discharge without distorting 100kHz–400kHz timing waveforms. Use Value: Sub-1µA leakage avoids pull-up current errors; 6.4V VBR accommodates 3.3V/5V I²C rail voltages. |
| Cellular Handset Antenna Switch Lines | Industrial HMI Touch Interface Lines |

IC Role / Device Role / Timing Role: High-speed transient suppressor placed inline with GPIO-controlled switch enable signals. Use Value: 15A IPP rating handles high-energy discharges near metal chassis; SOT23-3 allows placement adjacent to BGA-packaged RF modules. | Use Scenario: Protecting projected capacitive touch controller interrupt and reset lines in factory HMIs exposed to operator glove contact. IC Role / Device Role / Timing Role: Low-leakage ESD clamp on 3.3V logic lines interfacing with touch ICs and microcontrollers. Use Value: ±30kV air/contact rating meets EN 61000-6-2 industrial immunity requirements; –55°C to +125°C operation supports wide ambient deployment. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR | Single-channel, 12pF CT, 5.5V VRWM, lower capacitance but only one channel | Requires two devices for dual-line protection; better for high-speed USB 3.0 where capacitance is critical | Select when minimizing signal distortion on >480Mbps interfaces outweighs board area constraints |
| SMA6J5.0A | Single-channel, 600W PPP, 5.0V VBR, DO-214AC package, higher power but larger footprint | Used in power rail or high-energy surge scenarios; not suitable for high-density data lines | Choose for primary-level DC power line protection where SOT23 size is insufficient |
Compared with TPD2E001DRYR and SMA6J5.0A, the D5V0H2U3SO uniquely balances dual-channel integration, 156pF signal-line compatibility, and ±30kV ESD robustness in the smallest possible SMT package-making it optimal for space-constrained, battery-powered data interfaces requiring full IEC Level 4 compliance.

FAQ
What is the maximum clamping voltage of D5V0H2U3SO at 15A transient current?
The D5V0H2U3SO clamps to ≤20V at 15A peak pulse current (8/20µs waveform), as specified in its Electrical Characteristics table. This value ensures downstream components remain within safe operating limits during high-energy ESD events while maintaining compatibility with 5V-tolerant I/O structures.
Can D5V0H2U3SO be used for bidirectional ESD protection without external components?
Yes-by connecting Pin 1 to Pin 2, the device functions as a bidirectional suppressor with symmetrical clamping behavior. This configuration leverages internal series diode pairing to achieve ±30kV ESD protection on a single line without adding external resistors or capacitors.
Does D5V0H2U3SO meet automotive qualification standards?
No-the D5V0H2U3SO is not AEC-Q200 qualified. Diodes Incorporated explicitly states that automotive-grade variants require specific change control, PPAP capability, and IATF 16949 manufacturing; this part is intended for commercial and industrial applications only.
What is the thermal resistance (RθJA) of D5V0H2U3SO under standard PCB conditions?
The thermal resistance from junction to ambient is 500°C/W when mounted on a standard FR-4 PCB with 2oz copper per the layout shown in Diodes' package outline documentation. This value assumes no additional thermal vias or copper pour, and defines safe continuous power dissipation limits under steady-state conditions.
