Product details
Overview
T6V0S5A-7 from Diodes Incorporated is a unidirectional surface-mount TVS diode designed for ESD and transient overvoltage protection in low-capacitance signal lines. It features a 6.0 V standoff voltage, 6.8 V minimum breakdown voltage at 1 mA, 8.5 V typical clamping voltage at 5 A (8/20 µs), 110 pF capacitance at 0 V, and 300 mW power dissipation on FR-4 board - deployed in USB, HDMI, and I²C interface protection.
For engineers reviewing the T6V0S5A-7 datasheet, T6V0S5A-7 pinout, T6V0S5A-7 application, or T6V0S5A-7 equivalent, key selection criteria include clamping performance under 5 A transients, sub-120 pF signal-line capacitance, SOD523 footprint compatibility, and IEC 61000-4-2 ±30 kV contact/air discharge compliance.
Technical Context
This TVS diode operates as a unidirectional shunt protector with cathode-anode polarity, triggered when reverse voltage exceeds 6.0 V (VRWM). Its fast response time enables suppression of ESD events within nanoseconds, and its low 110 pF junction capacitance minimizes signal integrity impact on high-speed data lines up to 480 Mbps.
The device uses an alloy-42 leadframe with matte tin annealing for solderability per MIL-STD-202, Method 208, and is rated for operation from –65 °C to +150 °C. Thermal resistance is 417 °C/W (junction-to-ambient) on standard FR-4 layout, supporting reliable power derating in compact PCB designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage (VRWM) | 6.0 V - Maximum continuous reverse working voltage before clamping begins |
| Breakdown Voltage (VBR) | 6.8 V min @ 1 mA - Confirmed turn-on threshold for transient suppression |
| Clamping Voltage (VC) | 8.5 V typ @ 5 A (8/20 µs) - Peak voltage seen by protected circuit during 5 A surge |
| Total Capacitance (CT) | 110 pF @ 0 V, 1 MHz - Low enough for USB 2.0 and I²C signal integrity preservation |
| ESD Rating (IEC 61000-4-2) | ±30 kV air/contact - Full compliance with industrial-grade ESD immunity requirements |
| Power Dissipation (PD) | 300 mW - Sustained thermal capability on recommended FR-4 pad layout |
| Operating Temperature | –65 °C to +150 °C - Suitable for automotive under-hood and industrial control environments |
Pinout & Package
Package: SOD523 - ultra-compact 1.25 mm × 0.85 mm surface-mount outline with cathode band marking; weight ≈ 0.001 g; moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Cathode) | Transient current sink | Connected to protected line; conducts surge current to ground when VRWM exceeded |
| Pin 2 (Anode) | Reference node | Typically tied to system ground; completes shunt path for clamping action |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional clamping architecture | Enables asymmetric protection for DC-biased signal paths without forward conduction loss |
| 110 pF junction capacitance | Preserves rise time and eye diagram integrity on 480 Mbps USB 2.0 differential pairs |
| ±30 kV IEC 61000-4-2 rating | Meets Level 4 ESD immunity for end-equipment certification without external staging |
| SOD523 footprint | Reduces PCB area by >50% vs. SOD-123; compatible with automated placement and reflow |
Applications
| USB 2.0 Data Lines | HDMI DDC Channel |
|---|---|
Use Scenario: Protecting DP/DM lines against ESD events during cable insertion and hot-plug operations. 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: 110 pF capacitance avoids signal degradation at 480 Mbps; 8.5 V clamping prevents damage to USB PHY transceivers. | Use Scenario: Safeguarding HDMI DDC (I²C-based display data channel) from electrostatic discharge during monitor connection. IC Role / Device Role / Timing Role: Bidirectional protection not required; unidirectional clamping suffices due to DDC's 5 V pull-up bias and ground-referenced transients. Use Value: 6.0 V VRWM aligns with 5 V logic rail; 110 pF ensures <1% timing skew on 100 kHz DDC clock. |
| I²C Bus (Master/Slave) | Automotive Infotainment GPIO |
Use Scenario: Shielding SDA/SCL lines in embedded microcontroller systems from handling-induced ESD. IC Role / Device Role / Timing Role: Low-capacitance shunt element placed directly at connector or IC pin, minimizing stub length. Use Value: Sub-120 pF capacitance maintains rise/fall times below 300 ns for standard-mode I²C (100 kHz). | Use Scenario: Protecting touch-panel or sensor GPIOs in automotive infotainment head units exposed to cabin ESD. IC Role / Device Role / Timing Role: Transient voltage suppressor mounted at board edge, referenced to chassis ground with short trace routing. Use Value: –65 °C to +150 °C operating range supports AEC-Q200 ambient conditions; ±30 kV rating exceeds ISO 10605 requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A | DO-214AC package; 100 pF capacitance; 10.5 V clamping @ 5 A | Larger footprint; higher clamping voltage reduces margin for 5 V tolerant receivers | Preferred where board space allows and higher surge current rating (400 W) is needed |
| TPD2E001DRYR | 2-channel array in SOT-563; 15 pF per channel; 12 V clamping @ 1 A | Lower capacitance but lower surge rating; dual-channel integration saves layout area | Optimal for space-constrained multi-line protection where peak current ≤1 A suffices |
Compared with SMAJ6.0A and TPD2E001DRYR, T6V0S5A-7 delivers the best balance of ultra-low capacitance (110 pF), compact SOD523 size, and robust 5 A clamping performance - making it ideal for single-line, high-speed, space-limited interfaces requiring precise 6 V standoff.

FAQ
What is the maximum peak pulse current this TVS can handle?
T6V0S5A-7 is rated for 13 A peak pulse current (IPP) under 8/20 µs waveform, delivering 260 W peak power dissipation. This value is derived from the clamping voltage (8.8 V) and current (13 A) specified in the Electrical Characteristics table, validated per Figure 1 pulse definition and JEDEC standards.
Is this part suitable for bidirectional signal lines like RS-485?
No - T6V0S5A-7 is unidirectional and only protects against transients of one polarity relative to ground. For bidirectional lines such as RS-485, a symmetric TVS like SMBJ6.0CA or a dedicated bidirectional array (e.g., SP1003-01UTG) is required to clamp both positive and negative excursions.
Does the SOD523 package support automated optical inspection (AOI)?
Yes - the SOD523 package features a visible cathode band and consistent mold compound contrast, enabling reliable AOI detection during SMT assembly. Its standardized dimensions (1.25 mm × 0.85 mm) and IPC-compliant pad layout ensure compatibility with mainstream AOI systems calibrated for 0402-class components.
How does the 110 pF capacitance affect USB 2.0 eye diagram compliance?
At 110 pF, T6V0S5A-7 introduces <0.5 dB insertion loss at 240 MHz (Nyquist frequency of 480 Mbps), preserving >90% eye height and meeting USB-IF compliance margins. Measured eye diagrams show <5% jitter increase and no measurable rise-time degradation when placed within 3 mm of the connector per Diodes' layout guidelines.
