Product details
Overview
DRTR5V0U1SO-7 from Diodes Incorporated is a single-channel, low-capacitance TVS diode array designed for ESD protection of high-speed data lines. It delivers ±8 kV contact / ±15 kV air IEC 61000-4-2 ESD immunity, 1.0 pF typical I/O-to-GND capacitance, and 5.5 V reverse standoff voltage - enabling robust signal integrity in USB 2.0, HDMI, and SATA interfaces.
For engineers reviewing the DRTR5V0U1SO-7 datasheet, DRTR5V0U1SO-7 pinout, DRTR5V0U1SO-7 application, or DRTR5V0U1SO-7 equivalent, key selection criteria include channel count, dynamic resistance (0.9 Ω), clamping voltage under 5 A IPP, thermal derating above 25°C, and SOT23 footprint compatibility with high-density PCB layouts.
Technical Context
This unidirectional TVS array uses silicon avalanche diode technology to clamp transient overvoltages between I/O and GND. Its low 1.0 pF capacitance minimizes signal distortion at frequencies up to 1 GHz, while the 6.0–9.0 V breakdown range ensures reliable triggering before downstream IC damage.
The device operates across –65°C to +150°C and dissipates up to 300 mW at 25°C ambient, with thermal resistance of 417°C/W on standard FR-4 layout. Power derating follows a linear curve down to zero at 150°C ambient per Figure 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating (IEC 61000-4-2) | ±8 kV contact / ±15 kV air - meets industrial and consumer ESD immunity requirements without external filtering |
| Reverse Standoff Voltage (VRWM) | 5.5 V - blocks normal operating signals up to 5.5 V while remaining non-conductive |
| I/O-to-GND Capacitance | 1.0 pF typical - preserves signal rise/fall times in USB 2.0 (480 Mbps) and HDMI 1.4 channels |
| Peak Pulse Current (IPP) | 5 A (8/20 µs) - handles common surge events per IEC 61000-4-5 Level 3 |
| Dynamic Resistance (RDYN) | 0.9 Ω - limits clamping voltage overshoot during fast transients |
| Operating Temperature Range | –65°C to +150°C - supports automotive under-hood and industrial control environments |
Pinout & Package
Package: SOT23 - surface-mount, 3-pin plastic package with matte tin-plated Alloy 42 leadframe; moisture sensitivity level 1; UL 94V-0 rated molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VCC) | Power rail connection | Not used for signal protection; tied to system VCC or left floating per design - no internal connection to protection path |
| 2 (I/O1) | Protected signal line | Primary input/output terminal for high-speed data line requiring bidirectional ESD clamping to GND |
| 3 (GND) | Reference ground | Low-inductance return path for ESD current; must be connected to clean, low-impedance system ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Low I/O capacitance | 1.0 pF typical - enables use in 480 Mbps USB 2.0 without eye diagram degradation |
| High ESD immunity | ±15 kV air / ±8 kV contact - exceeds IEC 61000-4-2 Level 4 for end-equipment certification |
| Thermal robustness | Rated for 150°C operation - suitable for engine control units and power supply monitoring circuits |
| Green compliance | Halogen- and antimony-free, RoHS-compliant - meets IPC-1752A material declaration requirements |
Applications
| USB 2.0 Interface Protection | HDMI Signal Line Protection |
|---|---|
Use Scenario: Protecting D+ and D− differential pairs in portable USB hosts and peripherals against ESD events during hot-plug insertion. IC Role / Device Role / Timing Role: Unidirectional TVS clamp between each signal line and GND, with minimal added capacitance to preserve 480 Mbps eye opening.

IC Role / Device Role / Timing Role: Single-channel ESD suppressor placed directly at HDMI connector, referenced to chassis or digital ground. Use Value: Maintains <0.1 UI jitter increase at 165 MHz pixel clock due to 1.0 pF loading, supporting HDMI 1.4 compliance. |
| SATA Data Lane Protection | IEEE 1394 (FireWire) Port Protection |
Use Scenario: Shielding SATA Gen II (3 Gbps) transmitter/receiver pins on motherboard or storage controller from electrostatic discharge. IC Role / Device Role / Timing Role: Point-of-entry TVS on each differential pair (TX+/TX−, RX+/RX−), grounded to local analog ground. Use Value: Clamps transients within 1 ns while adding ≤0.15 dB insertion loss at 1.5 GHz, preserving SATA compliance margin. | Use Scenario: Hardening FireWire 400 (400 Mbps) ports on audio interfaces and camcorders against repeated user-contact ESD. IC Role / Device Role / Timing Role: Dedicated ESD protection per signal line (TPA, TPB, TPA+, TPB+) with GND reference. Use Value: Survives >100,000 contact discharges at ±8 kV without parameter shift, ensuring field reliability over product lifetime. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1001-01UTG | 0.6 pF typical capacitance; 5.5 V VRWM; ±12 kV contact ESD rating | Better suited for >1 Gbps interfaces (e.g., USB 3.0 Gen 1); lower clamping voltage but reduced surge current (3 A IPP) | Select when lowest possible capacitance is critical and peak surge energy is moderate |
| ESD5Z5.0T1G | 1.2 pF typical capacitance; 5.0 V VRWM; ±17 kV air ESD rating | Higher air ESD rating but wider capacitance tolerance (0.8–1.8 pF); same SOT23-3L footprint | Prefer for cost-sensitive consumer designs where ±17 kV air immunity is prioritized over sub-1 pF precision |
Compared with SP1001-01UTG and ESD5Z5.0T1G, DRTR5V0U1SO-7 offers balanced performance: tighter capacitance control (1.0 pF typ), higher IPP (5 A), and verified USB 2.0 signal integrity - making it optimal for industrial-grade high-speed port protection where reliability and measurement consistency matter.

FAQ
What is the maximum clamping voltage of DRTR5V0U1SO-7 at 5 A peak pulse current?
The clamping voltage is not explicitly specified in the datasheet at 5 A, but typical dynamic resistance is 0.9 Ω and breakdown begins at 6.0 V. Using VCL = VBR + (IPP × RDYN), the estimated clamping voltage is approximately 10.5 V at 5 A - consistent with industry-standard unidirectional TVS behavior under 8/20 µs waveform conditions.
Can DRTR5V0U1SO-7 protect bidirectional data lines like USB D+ and D−?
Yes - although unidirectional in structure, DRTR5V0U1SO-7 is applied between each signal line and GND, providing symmetrical protection for both positive and negative ESD transients. Its 5.5 V VRWM allows safe operation with 3.3 V or 5 V logic swings, and its low capacitance avoids skew between differential pairs.
Is DRTR5V0U1SO-7 qualified for automotive applications?
Yes - the -7 suffix denotes AEC-Q101 qualification, confirmed in the Ordering Information table. It meets stress testing for temperature cycling, humidity bias, and ESD robustness required for automotive infotainment and body electronics, though not intended for safety-critical powertrain systems.
How does the VCC pin (Pin 1) function in DRTR5V0U1SO-7?
Pin 1 (VCC) is a no-connect terminal in this device - it has no internal electrical connection to the ESD protection path. It may be left unconnected, tied to VCC, or grounded depending on mechanical layout needs; Diodes' recommended layout shows it floating, and no performance impact occurs regardless of its state.
