Product details
Overview
TPD3E001DRYRG4 from Texas Instruments is a 3-channel unidirectional ESD protection diode array designed for high-speed data interfaces including USB 2.0 micro-AB connectors. It delivers ±8-kV IEC 61000-4-2 contact and ±15-kV air-gap ESD protection, features 1.5-pF typical I/O capacitance per channel, <1-nA maximum leakage current, and operates across 0.9 V to 5.5 V supply range - enabling precision analog and portable medical applications like glucose meters.
For engineers reviewing the TPD3E001DRYRG4 datasheet, TPD3E001DRYRG4 pinout, TPD3E001DRYRG4 application, or TPD3E001DRYRG4 equivalent, key selection criteria include IEC Level-4 ESD rating, ultra-low 1.5-pF channel capacitance, 3-channel topology matching D+/D−/ID signal lines, thermal pad integration in USON package, and compatibility with 0.1-μF VCC bypass for optimal clamping performance.
Technical Context
The TPD3E001DRYRG4 implements a central ESD clamp architecture with two internal diodes per I/O line referenced to VCC and GND, enabling bidirectional transient suppression while maintaining low capacitive loading. Its passive operation activates only during overvoltage events (e.g., >11-V breakdown), reverting to high-impedance state within nanoseconds after voltage normalization.
It supports dual VCC biasing modes: connected to system supply (enabling clamping above VCC + 0.65 V) or left floating (allowing up to ±10-V signal swing), with mandatory 0.1-μF ceramic capacitor at VCC for ESD energy shunting. The device's 1.2-Ω dynamic resistance ensures robust 5.5-A peak pulse current handling under 8/20-μs waveform conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating (IEC 61000-4-2) | ±8-kV contact / ±15-kV air-gap - meets Level-4 international immunity standard for handheld interface ports |
| I/O Capacitance (per channel) | 1.5 pF typical at 5 V - preserves signal integrity on 480-Mbps USB 2.0 and other high-frequency data lines |
| Leakage Current | ±1 nA maximum at VIO = GND or VCC - avoids measurement drift in precision analog front-ends (e.g., biosensors) |
| Breakdown Voltage (VBR) | 11 V minimum at IBR = 10 mA - defines safe operating margin before clamping activation |
| Clamp Voltage (VC) | VCC + 60 V / −60 V at 24-A IEC contact discharge - limits stress on downstream USB transceivers |
| Supply Range (VCC) | 0.9 V to 5.5 V - supports single-supply operation across battery-powered and 3.3/5-V logic domains |
| Operating Temperature | −40°C to +85°C - qualified for industrial and portable consumer environments |
Pinout & Package
TPD3E001DRYRG4 uses a 6-pin USON (DRY) package measuring 1.45 mm × 1.00 mm × 0.6 mm max height, featuring an exposed thermal pad (EP) for enhanced thermal dissipation. The package is RoHS-compliant, moisture-sensitivity Level-1 rated, and optimized for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IO1 | ESD-protected I/O channel | Connects to D+ or first high-speed signal line; clamps transients to VCC/GND |
| IO2 | ESD-protected I/O channel | Connects to D− or second high-speed signal line; shares same clamping architecture as IO1 |
| IO3 | ESD-protected I/O channel | Connects to ID pin in USB OTG micro-AB connectors; enables role detection without added protection components |
| GND | Ground reference | Primary return path for ESD current; must be low-inductance connection to system ground plane |
| VCC | Power-supply input | Bias node for clamp circuitry; requires 0.1-μF ceramic capacitor to GND for effective surge suppression |
| EP | Exposed thermal pad | Internally connected to GND; improves thermal resistance (RθJB = 227.8°C/W) and mechanical stability |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E2U06 | 2-channel, lower 0.5-pF capacitance, higher ±12-kV HBM rating, no VCC pin | Optimized for space-constrained 2-line interfaces (e.g., HDMI CEC, I²C); lacks ID-line support for USB OTG | Select when protecting only D+/D− without ID, and ultra-low capacitance is prioritized over multi-channel integration |

FAQ
What is the primary function of the TPD3E001DRYRG4 in a USB 2.0 design?
The TPD3E001DRYRG4 serves as a 3-channel ESD protection array for USB 2.0 micro-AB connectors, safeguarding D+, D−, and ID signal lines against ±8-kV contact and ±15-kV air-gap ESD strikes per IEC 61000-4-2 Level 4. Its 1.5-pF per-channel capacitance ensures minimal impact on 480-Mbps data integrity, while the VCC-referenced clamp architecture provides adaptive voltage limiting. This makes the TPD3E001DRYRG4 essential for maintaining compliance and reliability in portable USB-connected devices.
Does the TPD3E001DRYRG4 require an external power supply to operate?
No, the TPD3E001DRYRG4 is a passive TVS diode array and does not require active power to perform ESD suppression. However, its VCC pin must be externally biased - either connected to the system supply (0.9 V to 5.5 V) or left floating - to enable proper clamping behavior. A 0.1-μF ceramic capacitor is mandatory between VCC and GND to absorb surge energy during ESD events. Without this capacitor, the TPD3E001DRYRG4 cannot achieve specified IEC 61000-4-2 performance.
How does the TPD3E001DRYRG4 differ from the TPD2E2U06 in terms of USB interface support?
The TPD3E001DRYRG4 provides exactly three protected channels (IO1–IO3), matching the D+, D−, and ID pins of a USB micro-AB connector - enabling full OTG functionality. In contrast, the TPD2E2U06 offers only two channels and no VCC pin, making it unsuitable for ID-line protection or VCC-referenced clamping. While the TPD2E2U06 achieves lower 0.5-pF capacitance, it cannot replace the TPD3E001DRYRG4 in micro-AB USB applications without adding discrete components or redesigning the protection scheme.
Can the TPD3E001DRYRG4 be used to protect analog sensor inputs in medical devices?
Yes, the TPD3E001DRYRG4 is explicitly validated for precision analog interfaces in medical applications such as blood glucose meters. Its ≤1-nA maximum leakage current prevents DC offset errors in millivolt-range electrochemical signals, and its 1.5-pF channel capacitance avoids filtering critical low-frequency biosensor waveforms. TI documentation confirms successful deployment in heart rate monitors and glucose sensors where ESD robustness and analog accuracy are jointly required - making the TPD3E001DRYRG4 a qualified choice for Class II medical electronics.
What is the significance of the exposed thermal pad (EP) on the TPD3E001DRYRG4 DRY package?
The exposed thermal pad (EP) on the TPD3E001DRYRG4's 6-pin USON package is internally connected to GND and serves two critical functions: it lowers junction-to-board thermal resistance (RθJB = 227.8°C/W), improving power dissipation during high-current ESD events, and enhances mechanical anchoring for reliability in vibration-prone portable devices. TI's layout guidelines require the EP to be soldered to a dedicated GND copper pour using ≥4 thermal vias - omitting this step risks thermal runaway during ±15-kV air-gap discharges and compromises long-term solder joint integrity.
