Product details
Overview
T2V5S5-7 from Diodes Incorporated is a unidirectional surface-mount TVS diode designed for ESD protection in high-speed data lines, with 2.5 V reverse standoff voltage, 4.0 V minimum breakdown voltage at 1.0 mA, 6.5 V clamping voltage at 5 A (8/20 µs), 70 pF typical capacitance at 0 V and 1 MHz, and SOD-523 package. It protects USB 2.0, HDMI, and audio interfaces against IEC61000-4-2 ±30 kV air/contact discharge.
For engineers reviewing the T2V5S5-7 datasheet, T2V5S5-7 pinout, T2V5S5-7 application, or T2V5S5-7 equivalent, key selection criteria include clamping voltage under 5 A surge, low capacitance for signal integrity, ESD rating compliance, thermal resistance (833 °C/W), and SOD-523 footprint compatibility with space-constrained PCB layouts.
Technical Context
This TVS diode operates as a unidirectional transient suppressor, conducting only during negative transients relative to its cathode-marked terminal. Its silicon avalanche structure delivers sub-nanosecond response time and clamps transients within 6.5 V at 5 A peak pulse current (8/20 µs waveform), ensuring robust protection without signal distortion.
Rated for -65 °C to +150 °C operation, it features 12 µA max reverse leakage at 2.5 V standoff, 150 mW power dissipation on FR-4 board, and 833 °C/W junction-to-ambient thermal resistance-enabling reliable performance in portable and automotive infotainment systems where thermal margin is constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 2.5 V - Maximum continuous working voltage before clamping begins; sets operating margin for 3.3 V logic rails. |
| Breakdown Voltage (min) | 4.0 V at 1.0 mA - Ensures reliable avalanche conduction onset above normal signal swing. |
| Clamping Voltage | 6.5 V at 5 A (8/20 µs) - Limits transient voltage seen by protected ICs to safe levels during ESD events. |
| Total Capacitance | 70 pF at 0 V, 1 MHz - Low enough to avoid signal degradation in USB 2.0 (480 Mbps) and audio paths. |
| ESD Rating | ±30 kV IEC61000-4-2 air/contact - Meets industrial and consumer end-equipment immunity requirements. |
| Package | SOD-523 - 1.6 × 1.2 mm footprint with cathode band marking; enables high-density routing on compact PCBs. |
| Thermal Resistance | 833 °C/W - Requires minimal copper area for thermal management in handheld devices. |
Pinout & Package
Package: SOD-523 - ultra-compact surface-mount plastic case (1.6 × 1.2 × 0.8 mm), molded with UL 94V-0 green compound, matte tin-plated terminals, cathode band marking, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient return path | Connected to ground or low-impedance reference; completes clamping loop during negative surges. |
| Cathode | Protected line connection | Connected to signal line (e.g., USB D+, HDMI TMDS+); blocks DC but conducts ESD transients to ground. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 70 pF enables use on 480 Mbps USB 2.0 differential pairs without eye diagram degradation. |
| Fast response time | Sub-nanosecond turn-on ensures clamping occurs before sensitive downstream ICs experience overvoltage stress. |
| High ESD immunity | ±30 kV contact discharge rating exceeds IEC61000-4-2 Level 4, eliminating need for secondary protection layers. |
| Green RoHS-compliant construction | Lead-free, halogen-free molding compound and matte tin terminations meet global environmental compliance mandates. |
Applications
| USB 2.0 Interface Protection | HDMI Signal Line Protection |
|---|---|
Use Scenario: Protecting USB 2.0 D+ and D− lines in smartphones and docking stations from human-body ESD events. IC Role / Device Role / Timing Role: Unidirectional TVS placed between connector and PHY IC to clamp transients while preserving 480 Mbps data integrity. Use Value: 70 pF capacitance prevents signal rise-time degradation; 6.5 V clamping avoids PHY latch-up during ±30 kV contact discharge. | Use Scenario: Safeguarding HDMI TMDS channels in set-top boxes and monitors against cable-discharge events. IC Role / Device Role / Timing Role: Single-channel TVS per TMDS+ line, grounded via short trace to minimize inductance and maintain 165 MHz bandwidth. Use Value: 2.5 V standoff aligns with HDMI common-mode range; low leakage (<12 µA) prevents DC bias shift in AC-coupled links. |
| Portable Audio Jack Protection | Automotive Infotainment Data Lines |
Use Scenario: Shielding 3.5 mm audio jack MIC and GND lines in Bluetooth headsets from user-hand ESD. IC Role / Device Role / Timing Role: Bidirectional protection implemented using two unidirectional T2V5S5-7 devices back-to-back per line. Use Value: SOD-523 size fits tight jack-area layouts; 12 µA leakage avoids microphone bias circuit interference. | Use Scenario: Protecting LVDS or UART lines in automotive center displays exposed to ISO 10605 pulses. IC Role / Device Role / Timing Role: Point-of-entry TVS on harness-side connectors to absorb transients before reaching MCU or display driver ICs. Use Value: -65 °C to +150 °C operating range supports under-hood and dashboard mounting; 833 °C/W RθJA allows passive cooling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ2.5A | DO-214AC package (4.5 × 2.7 mm); 7.5 V clamping at 5 A; 150 pF capacitance. | Higher clamping voltage and capacitance limit use to lower-speed interfaces (e.g., RS-232). | Select when board space permits larger package and higher clamping is acceptable for cost-sensitive industrial designs. |
| ESD5Z2.5 | SOD-523 package; 2.5 V standoff; 6.8 V clamping at 5 A; 45 pF capacitance. | Lower capacitance improves RF and high-speed digital performance but reduced surge handling (12 W vs. 220 W peak power). | Prefer for ultra-high-speed applications like MIPI D-PHY where <50 pF is mandatory, accepting lower peak power rating. |
Compared with SMAJ2.5A and ESD5Z2.5, T2V5S5-7 uniquely balances low capacitance (70 pF), moderate clamping (6.5 V), and high peak power (220 W) in the smallest SOD-523 footprint-making it optimal for space-constrained, high-data-rate consumer electronics.

FAQ
What is the maximum clamping voltage of T2V5S5-7 under IEC61000-4-2 surge conditions?
The T2V5S5-7 clamps to a maximum of 8.1 V at 5 A peak pulse current (8/20 µs waveform), as specified in the datasheet's electrical characteristics table. This value represents worst-case clamping under standardized surge testing and ensures downstream ICs remain within absolute maximum ratings during ±30 kV ESD events.
Can T2V5S5-7 be used for bidirectional signal lines like USB D+/D− without additional components?
No-T2V5S5-7 is unidirectional and must be paired with a second device in series-opposing configuration to protect bidirectional lines. For true bidirectional protection, Diodes offers the dual-channel D3V3S5M-7, which integrates matched unidirectional TVS elements in one SOD-523 package.
How does the SOD-523 package affect thermal performance in continuous operation?
The SOD-523 package has a junction-to-ambient thermal resistance of 833 °C/W on FR-4 board with recommended pad layout. Under continuous DC bias, power dissipation is limited to 150 mW; sustained operation near this limit requires careful PCB copper area design to avoid exceeding the -65 °C to +150 °C operating temperature range.
Is T2V5S5-7 compliant with automotive AEC-Q200 stress test requirements?
No-T2V5S5-7 is not AEC-Q200 qualified. While it operates from -65 °C to +150 °C and meets IEC61000-4-2 ESD standards, it lacks qualification for automotive-grade temperature cycling, humidity bias, and mechanical shock tests required by AEC-Q200. For automotive applications, consider Diodes' AEC-Q200-qualified PTVS2.5S1UR series.
