Product details
Overview
T5V0S5-7 from Diodes Incorporated is a unidirectional surface-mount TVS diode designed for ESD and transient overvoltage protection in low-voltage signal lines. It features a 5.0 V reverse standoff voltage, 6.2 V minimum breakdown voltage at 1 mA, 10 V typical clamping voltage at 5 A (8/20 µs), <0.05 µA reverse leakage at VRWM, and SOD523 package with cathode band marking.
For engineers reviewing the T5V0S5-7 datasheet, T5V0S5-7 pinout, T5V0S5-7 application, or T5V0S5-7 equivalent, key selection criteria include clamping performance under 5 A surge, low capacitance (100 pF @ 0 V, 1 MHz), thermal resistance (417 °C/W), and compatibility with high-speed USB, HDMI, and I²C interfaces requiring sub-100 pF ESD protection.
Technical Context
This TVS diode operates as a unidirectional clamp, conducting only during negative transients relative to its anode-cathode orientation. Its fast response time (<1 ns) and low dynamic impedance enable effective suppression of ESD events per IEC61000-4-2 (±30 kV air/contact) and human body model (8 kV).
The device is optimized for low-capacitance signal-line protection without compromising clamping robustness: 100 pF total capacitance minimizes signal distortion in 100 Mbps+ digital interfaces, while 300 mW power dissipation and 417 °C/W junction-to-ambient thermal resistance support operation on standard FR-4 PCBs with recommended pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5.0 V - Maximum continuous DC or RMS voltage before significant leakage begins; sets operating margin for 3.3 V or 5 V logic rails. |
| Breakdown Voltage (min) | 6.2 V @ 1 mA - Ensures reliable conduction onset above normal operating voltage, preventing false triggering. |
| Clamping Voltage (typ) | 10 V @ 5 A, 8/20 µs - Limits peak transient voltage seen by downstream ICs during surge events. |
| Reverse Leakage Current | <0.05 µA @ 5.0 V - Negligible loading on high-impedance signal paths such as I²C or GPIO. |
| Total Capacitance | 100 pF @ 0 V, 1 MHz - Enables use in USB 2.0 (480 Mbps), HDMI DDC, and other <1 GHz digital interfaces. |
| ESD Rating (HBM) | 8 kV - Meets IEC61000-4-2 Level 4 immunity requirements for end-equipment compliance. |
| Package | SOD523 - 1.25 mm × 0.85 mm footprint; compatible with automated pick-and-place and reflow soldering. |
Pinout & Package
Package: SOD523 - ultra-small plastic surface-mount package with cathode band marking; dimensions: 1.25 mm (E) × 0.85 mm (D) × 0.65 mm (A max); weight ≈ 0.001 g; moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current sink path during negative excursions | Connected to protected signal line; conducts when voltage drops below cathode by >0.9 V forward drop. |
| Cathode | Reference terminal / ground connection point | Connected to system ground or low-impedance return path; defines polarity and clamping reference. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional clamping architecture | Protects against negative transients only-ideal for DC-biased signal lines like USB D+/D− or UART TX/RX. |
| Low 100 pF capacitance | Maintains signal integrity in high-speed interfaces without added jitter or rise-time degradation. |
| ±30 kV IEC61000-4-2 ESD rating | Meets industrial and consumer equipment immunity standards without external shielding or filtering. |
| SOD523 footprint | Enables dense PCB layouts in space-constrained applications such as wearables and IoT sensors. |
| Lead-free, halogen-free, RoHS 3 compliant | Supports global environmental compliance and eliminates antimony/bromine compounds per Diodes' "Green" definition. |
Applications
| USB 2.0 Data Lines | HDMI DDC Channel |
|---|---|
Use Scenario: Protecting differential USB 2.0 D+ and D− lines from ESD events during cable insertion or handling. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between each data line and ground, referenced to common-mode voltage. Use Value: 100 pF capacitance avoids signal integrity loss at 480 Mbps; 10 V clamping prevents damage to USB transceivers rated for ≤12 V absolute maximum. | Use Scenario: Safeguarding HDMI Display Data Channel (DDC) lines (SCL/SDA) from hot-plug ESD and cable discharge. IC Role / Device Role / Timing Role: Low-leakage (0.05 µA) bidirectional protection element on open-drain I²C bus lines. Use Value: Sub-0.1 µA leakage preserves I²C pull-up functionality; 5.0 V standoff aligns with 3.3 V DDC supply rail. |

IC Role / Device Role / Timing Role: Point-of-entry transient suppressor on single-ended signal traces routed across noisy industrial enclosures. Use Value: 417 °C/W thermal resistance allows safe energy dissipation on compact sensor PCBs without heatsinking. | Use Scenario: Protecting touch controller, display, or audio codec I/O pins in automotive infotainment head units exposed to cabin ESD. IC Role / Device Role / Timing Role: Front-end ESD guard for low-voltage CMOS inputs operating at 1.8 V–5.0 V supply domains. Use Value: 8 kV HBM rating exceeds ISO 10605 requirements for component-level ESD testing in vehicle environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | DO-214AC package (larger), 5.0 V standoff, 9.2 V clamping @ 5 A, 200 pF capacitance | Higher capacitance limits use to lower-speed interfaces (≤10 Mbps); better surge handling (400 W PPK) | Select when higher surge power rating is required and board space permits larger package. |
| ESD5Z5.0T1G | SOD-523 package, 5.0 V standoff, 12.5 V clamping @ 5 A, 65 pF capacitance, 1.5 kV HBM | Lower capacitance benefits RF/analog lines; weaker ESD rating reduces suitability for harsh environments | Choose for ultra-low-capacitance needs where ±30 kV IEC61000-4-2 is not mandated. |
Compared with SMAJ5.0A and ESD5Z5.0T1G, T5V0S5-7 delivers optimal balance of low capacitance (100 pF), industry-leading ±30 kV ESD immunity, and minimal footprint-making it preferred for high-speed, space-constrained, and regulatory-compliant designs.

FAQ
Is T5V0S5-7 suitable for bidirectional signal lines like RS-485 or CAN?
No. T5V0S5-7 is unidirectional and protects only negative transients relative to its cathode. For bidirectional lines such as RS-485 or CAN, a symmetric (bidirectional) TVS like SMBJ5.0CA or D24Z5.1 is required to clamp both polarities equally.
What is the meaning of the "-7" suffix in T5V0S5-7?
The "-7" suffix denotes tape-and-reel packaging: 3000 units per 8 mm wide reel, dispensed in every other cavity. It does not indicate a revision or functional variant-the electrical and mechanical specifications match the base T5V0S5 part.
Can T5V0S5-7 replace T3V3S5 in a 3.3 V system?
No. T3V3S5 has a 3.3 V standoff and clamps at ~8.4 V, making it appropriate for 3.3 V rails. Using T5V0S5-7 (5.0 V standoff) risks insufficient protection margin-transients may exceed the IC's absolute maximum rating before clamping activates.
Does T5V0S5-7 require derating at elevated ambient temperatures?
Yes. At 85°C ambient, its peak pulse power must be reduced to ~210 mW (70% of 300 mW rating) due to thermal limitations. Derating curves are provided in Figure 2 of DS31112; PCB copper area and airflow significantly affect actual performance.
