Product details
Overview
T5V0S5A-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, 7.6 V typical clamping voltage at 5 A (8/20 µs), 130 pF capacitance at 0 V, <0.05 µA reverse leakage at VRWM, and IEC61000-4-2 ±30 kV contact/air discharge rating - deployed in USB 2.0 data lines, HDMI interface protection, and portable consumer electronics.
For engineers reviewing the T5V0S5A-7 datasheet, T5V0S5A-7 pinout, T5V0S5A-7 application, or T5V0S5A-7 equivalent, key selection criteria include clamping performance under 5 A surge, low capacitance for high-speed signal integrity, SOD523 footprint compatibility, and automotive-grade ESD robustness without requiring board-level filtering.
Technical Context
This TVS operates as a unidirectional shunt device with cathode-banded polarity, triggered when reverse voltage exceeds 6.2 V (min breakdown). Its fast response time (<1 ns) enables suppression of ESD transients before IC damage occurs, while its low thermal resistance (417 °C/W) supports reliable power dissipation up to 300 mW on FR-4 PCBs with recommended pad layout.
The device uses alloy 42 leadframe with matte tin annealed terminals, rated for -65°C to +150°C operation, and complies with J-STD-020 Level 1 moisture sensitivity. Its green molding compound meets UL 94V-0 flammability and RoHS 3 / halogen-free requirements.

| Halogen & antimony free | <900 ppm Br/Cl, <1000 ppm Sb - satisfies EU ELV and OEM green material declarations |
Applications
| USB 2.0 Data Lines | HDMI Interface Protection |
|---|---|
Use Scenario: Protecting D+ and D- pins of USB 2.0 transceivers against ESD events during hot-plug insertion. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between signal line and ground, activated only during negative transients relative to ground. Use Value: 130 pF capacitance avoids signal degradation at 480 Mbps; 7.6 V clamping prevents damage to 3.3 V tolerant PHY inputs. | Use Scenario: Safeguarding TMDS clock and data channels in HDMI 1.4 receivers from cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance TVS mounted directly at connector, referenced to chassis ground to suppress common-mode surges. Use Value: ±30 kV IEC61000-4-2 rating meets HDMI compliance test requirements; SOD523 allows placement within 2 mm of connector pads. |
| Smartphone Button Interfaces | Industrial Sensor Signal Conditioning |
Use Scenario: ESD protection for mechanical or capacitive touch buttons connected to microcontroller GPIOs. IC Role / Device Role / Timing Role: Bidirectional protection not required; unidirectional configuration minimizes leakage (<0.05 µA) to preserve battery life. Use Value: Sub-1 µA leakage at 5 V standoff extends standby time in always-on button circuits; small SOD523 fits behind thin bezels. | Use Scenario: Shielding 4–20 mA analog input lines in PLC modules from field-induced transients. IC Role / Device Role / Timing Role: Shunt limiter placed before op-amp buffer stage to clamp surges before signal conditioning circuitry. Use Value: 300 mW power rating handles repetitive 1 kV/500 Ω surge pulses per IEC 61000-4-4; -65°C to +150°C range supports extended industrial temperature operation. |
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 (4.5 mm × 2.7 mm); 10.8 V clamping @ 5 A; 350 pF capacitance | Higher clamping voltage and capacitance limit use to lower-speed analog or power rails | Select when board space permits larger footprint and higher surge energy (400 W) is needed |
| TPD2E001DRYR | 2-channel array in SOT-563; 12 pF per channel; 5.5 V standoff; integrated ESD protection | Designed specifically for USB/HDMI differential pairs; lower capacitance but lower surge rating (4 A) | Prefer for multi-line protection where layout density and signal integrity outweigh single-device surge margin |
Compared with SMAJ5.0A and TPD2E001DRYR, T5V0S5A-7 delivers optimal balance of low clamping (7.6 V), moderate surge capability (15 W peak), and compact size (SOD523) for discrete high-speed signal line protection - especially where cost-sensitive, single-line, and space-constrained designs dominate.

FAQ
What is the maximum peak pulse current the T5V0S5A-7 can handle?
The T5V0S5A-7 is rated for 15 A peak pulse current (IPP) at 8/20 µs waveform, corresponding to a maximum clamping voltage of 17.3 V. This value is derived from the VC2 specification in the Electrical Characteristics table and validated under JEDEC-standard surge conditions.
Does T5V0S5A-7 support bidirectional ESD protection?
No - T5V0S5A-7 is strictly unidirectional. It clamps only when the cathode is more positive than the anode. For bidirectional protection, Diodes offers the T5V0S5B-7 variant, which uses a symmetrical dual-diode configuration in the same SOD523 package.
Can T5V0S5A-7 be used in automotive applications?
The standard T5V0S5A-7 is not AEC-Q101 qualified. However, the automotive-grade version T5V0S5AQ is identical in electrical specs and package but undergoes additional stress testing per AEC-Q101, making it suitable for infotainment and body electronics in passenger vehicles.
What is the recommended PCB pad layout for optimal thermal and electrical performance?
Diodes specifies a 0.80 mm × 0.60 mm pad (G × X), 2.00 mm pad length (X1), and 0.70 mm pad width (Y) for SOD523. Use thermal relief vias near the cathode pad to enhance heat dissipation, and keep trace inductance below 1 nH by minimizing distance to ground plane - details are published in Diodes' package outline document PN-00001.
