Product details
Overview
T5V0S5AQ-7 from Diodes Incorporated is a unidirectional surface-mount TVS diode designed for ESD protection of automotive infotainment and ADAS signal lines. It features a 5.0 V reverse standoff voltage, 6.2 V minimum breakdown voltage at 1.0 mA, 7.6 V clamping voltage at 5 A (8/20 µs), 130 pF typical junction capacitance at 0 V, and ±30 kV IEC 61000-4-2 contact/air discharge rating.
For engineers reviewing the T5V0S5AQ-7 datasheet, T5V0S5AQ-7 pinout, T5V0S5AQ-7 application, or T5V0S5AQ-7 equivalent, this part delivers verified AEC-Q101 qualification, SOD523 package compatibility with high-density PCB layouts, and precise clamping performance for 5 V rail protection in safety-critical automotive interfaces.
Technical Context
This TVS operates as a unidirectional clamp between I/O and ground, leveraging avalanche breakdown to divert ESD transients while maintaining low leakage (<0.05 µA at VRWM). Its 130 pF capacitance and 7.6 V clamping at 5 A support high-speed data lines such as USB 2.0 and CAN FD without signal integrity degradation.
The device uses a planar silicon junction structure in an SOD523 package with cathode band marking, optimized for thermal dissipation (RθJA = 417 °C/W) and robust surge handling (15 A peak pulse current, 260 W peak power).
Key Specifications

|---|---|
| Reverse Standoff Voltage | 5.0 V - Maximum continuous DC voltage before significant leakage; sets operating margin for 5 V logic rails. |
| Breakdown Voltage (Min) | 6.2 V @ 1.0 mA - Guaranteed avalanche initiation threshold; ensures reliable triggering before system damage. |
| Clamping Voltage | 7.6 V @ 5 A (8/20 µs) - Peak voltage seen by protected IC during ESD event; enables safe operation of 5 V interface ICs. |
| Junction Capacitance | 130 pF @ 0 V, 1 MHz - Low enough for USB 2.0 (480 Mbps) and CAN FD (5 Mbps) without measurable signal distortion. |

Applications
| USB 2.0 Interface Protection | CAN FD Bus Protection |
|---|---|
Use Scenario: Protecting USB 2.0 data lines (D+/D−) in automotive infotainment head units against ESD from user interaction. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed directly at connector entry point to limit transient voltage to ≤7.6 V. Use Value: 130 pF capacitance avoids signal rise-time degradation; ±30 kV rating prevents latch-up or damage to USB transceivers. | Use Scenario: Safeguarding CAN FD high-speed bus lines (CANH/CANL) in ADAS domain controllers exposed to ESD during service or assembly. IC Role / Device Role / Timing Role: Single-channel unidirectional clamp on each line referenced to chassis ground, ensuring bus differential integrity. Use Value: 7.6 V clamping maintains common-mode voltage within ISO 11898-2 tolerance; 15 A IPP handles multiple ESD strikes without parametric shift. |
| Touchscreen Controller I/O | Automotive Telematics LTE Antenna Feed |
Use Scenario: Shielding capacitive touchscreen controller GPIOs (e.g., reset, interrupt) from ESD induced through front panel glass. IC Role / Device Role / Timing Role: Point-of-use TVS on each sensitive control line, placed adjacent to IC pad to minimize inductance. Use Value: 0.05 µA leakage at 5 V ensures no impact on touch sensitivity or power budget; SOD523 size fits tight layout constraints. | Use Scenario: Protecting RF front-end components (e.g., LTE antenna switch, LNA input) from ESD coupling via antenna feed traces. IC Role / Device Role / Timing Role: Series-connected unidirectional TVS on antenna path to ground, preserving RF impedance match below 3 GHz. Use Value: 130 pF capacitance introduces negligible reactance at LTE bands (700–2600 MHz); 5.0 V VRWM aligns with bias voltage of RF switches. |
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); 5.0 V VRWM; 100 A IPP; 100 pF CT | Larger footprint; higher surge capacity but unsuitable for fine-pitch automotive PCBs | Select when higher surge endurance (>15 A) is required and board space permits larger package. |
| TPD2E001DRYR | 2-channel bidirectional array; 5.5 V VRWM; 12 V VC @ 1 A; 12 pF CT; SOT-553 | Lower capacitance ideal for USB 3.0; lacks AEC-Q101 qualification and automotive PPAP support | Choose for non-automotive, high-speed digital interfaces where ultra-low capacitance outweighs qualification needs. |
Compared with SMAJ5.0A and TPD2E001DRYR, T5V0S5AQ-7 uniquely balances AEC-Q101 compliance, SOD523 miniaturization, and 130 pF/7.6 V performance-making it optimal for space-constrained, safety-certified automotive signal protection where both ESD robustness and layout density are critical.

FAQ
What is the maximum operating temperature for T5V0S5AQ-7?
The T5V0S5AQ-7 is rated for junction temperatures from –55 °C to +150 °C, with derated power dissipation above +25 °C ambient per the published thermal curve. At +125 °C ambient, its usable peak pulse power drops to approximately 180 W due to RθJA = 417 °C/W and thermal limits.
Is T5V0S5AQ-7 compatible with lead-free reflow soldering processes?
Yes, T5V0S5AQ-7 uses matte tin annealed terminals over Alloy 42 leadframe and is fully compatible with standard Pb-free reflow profiles (JEDEC J-STD-020, peak 260 °C). Its SOD523 package has moisture sensitivity level 1, eliminating bake requirements prior to assembly.
Does T5V0S5AQ-7 require external series resistance for optimal ESD protection?
No external series resistor is required for basic ESD clamping. However, in high-speed data lines (e.g., USB 2.0), a small series resistor (e.g., 0–10 Ω) may be added near the connector to dampen ringing without affecting clamping response time, as confirmed in Diodes' application note AN-4001.
How does the clamping voltage of T5V0S5AQ-7 vary with different peak pulse currents?
Per Figure 1 in DS45280 Rev. 2-2, clamping voltage rises from 7.6 V at 5 A to 9.4 V at 15 A (8/20 µs), remaining linear and predictable. This behavior ensures consistent protection margins across the full specified surge range without snapback or secondary breakdown.
