Product details
Overview
SN65220IDBVRQ1 from Texas Instruments is a dual-channel unidirectional transient voltage suppressor (TVS) designed for ESD protection of USB full-speed and low-speed data lines (D+ and D−). It features 6.5-V minimum breakdown voltage, 35-pF typical input capacitance, ≤1-µA leakage at 6 V, −40°C to 85°C operating range, and SOT-23-6 package with verified pinout A/D+/B/D−/GND/GND.
For engineers reviewing the SN65220IDBVRQ1 datasheet, SN65220IDBVRQ1 pinout, SN65220IDBVRQ1 application, or SN65220IDBVRQ1 equivalent, this page delivers verified electrical specs, USB port-level ESD protection context, thermal resistance data (199.5°C/W RθJA), functional mode behavior, and real-world layout guidance for robust board-level implementation.
Technical Context
The SN65220IDBVRQ1 integrates two independent unidirectional TVS diodes in a single SOT-23-6 package, each protecting one USB differential line. Its Zener-triggered bipolar structure provides precise 6.5–8-V breakdown with fast response to ±15-kV HBM transients while maintaining high-impedance standby operation below standoff voltage.
It operates without external power supply, relying solely on transient overvoltage activation. The dual-GND pin configuration (pins 2 and 5) minimizes ground path inductance, supporting effective shunting of ESD energy directly to local PCB ground plane-critical for meeting IEC 61000-4-2 system-level compliance when combined with proper layout.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRSR | Single-channel, 1.5-pF capacitance, 5.5-V standoff, SOT-5X3 package | Better suited for high-speed USB 2.0; lacks dual-channel integration and automotive qualification | Select when ultra-low capacitance is mandatory and discrete channel routing is acceptable |
| ESD5451N-2/TR | Dual-channel, 0.5-pF capacitance, 5.5-V standoff, DFN1006-3L package | Higher ESD rating (±25 kV HBM) but no AEC-Q100 qualification; lower thermal mass limits surge repetition rate | Prefer for consumer electronics where cost and size outweigh automotive reliability requirements |
Compared with TPD2E001DRSR and ESD5451N-2/TR, SN65220IDBVRQ1 offers integrated dual-channel protection with automotive-grade temperature range and proven USB full-speed compatibility-making it optimal for space-constrained, mission-critical USB ports where layout simplicity and qualification assurance are prioritized over sub-1-pF capacitance.

FAQ
What is the primary function of the SN65220IDBVRQ1 in a USB interface?
The SN65220IDBVRQ1 serves as a dual-channel unidirectional transient voltage suppressor that protects USB D+ and D− lines from ESD and electrical noise transients. It clamps voltages above 6.5 V to prevent damage to downstream USB transceivers, while maintaining low 35-pF capacitance to preserve signal integrity at 12 Mbps. Its design ensures reliable operation in automotive and industrial USB ports where robustness is critical.
Does the SN65220IDBVRQ1 support USB 2.0 high-speed operation?
No, the SN65220IDBVRQ1 does not support USB 2.0 high-speed (480 Mbps) operation. Its 35-pF typical input capacitance introduces excessive signal attenuation and timing skew at high frequencies. The datasheet explicitly states it is intended for USB low-speed (1.5 Mbps) and full-speed (12 Mbps) applications only. For high-speed USB, lower-capacitance alternatives such as TPD2E001DRSR (1.5 pF) are required.
How is the SN65220IDBVRQ1 qualified for automotive use?
The SN65220IDBVRQ1 is AEC-Q100 qualified as an automotive-grade part (indicated by the "Q1" suffix). It meets Grade 2 temperature requirements (−40°C to +105°C junction, −40°C to +85°C ambient), undergoes rigorous stress testing including HTOL, TC, and ESD, and is manufactured in TI's certified automotive production lines. This qualification ensures long-term reliability in vehicle infotainment, telematics, and charging systems.
Why does the SN65220IDBVRQ1 have two GND pins (pins 2 and 5)?
The SN65220IDBVRQ1 includes two dedicated GND pins (2 and 5) to minimize inductance in the transient current return path-one for each protected line (A/D+ and B/D−). This dual-ground architecture reduces L·di/dt voltage overshoot during fast ESD events, enabling faster clamping and more effective energy diversion to the PCB ground plane. Layout guidelines require both pins to be connected directly to a solid ground plane via multiple vias.
Can the SN65220IDBVRQ1 be used without external power supply connections?
Yes, the SN65220IDBVRQ1 requires no external power supply. It is a passive silicon-based TVS device composed of integrated Zener-triggered bipolar structures. It remains in high-impedance standby mode during normal operation and activates only when transient voltage exceeds its 6.5-V breakdown threshold. This eliminates supply rail dependencies and simplifies integration into any USB data path.
