Product details
Overview
TPD4E001DRLRG4 from Texas Instruments is a four-channel unidirectional ESD protection diode array designed for high-speed data interfaces. It delivers ±8kV contact / ±15kV air-gap IEC 61000-4-2 Level 4 ESD protection, 1.5pF typical IO capacitance per channel, <1nA maximum leakage current, and operates across 0.9V–5.5V supply range - enabling robust protection of USB 2.0 differential pairs without signal integrity degradation.
For engineers reviewing the TPD4E001DRLRG4 datasheet, TPD4E001DRLRG4 pinout, TPD4E001DRLRG4 application, or TPD4E001DRLRG4 equivalent, key selection criteria include low-capacitance channel protection, VCC-referenced clamping architecture, SOT-5X3 (DRL) package compatibility with high-density layouts, and verified performance in LVDS, FireWire™, and medical glucose meter interfaces.
Technical Context
The TPD4E001DRLRG4 implements a central ESD clamp with dual-diode per-line topology referenced to both GND and VCC, enabling bidirectional transient suppression on IOx pins while protecting the power rail. Its unidirectional structure triggers at ~11V breakdown (VBR) and clamps ±15kV IEC strikes to ≤VCC + 100V (positive) or –100V (negative) at 45A peak pulse current.
Designed for passive operation, it reverts to high-impedance state within nanoseconds after ESD events subside. The DRL package's 1.60mm × 1.20mm body size and 0.65mm profile support placement directly adjacent to connectors - minimizing trace inductance and preventing EMI coupling into unprotected nets during discharge.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating (IEC 61000-4-2) | ±8kV contact / ±15kV air-gap - meets Level 4 immunity for industrial and consumer USB/Ethernet ports |
| IO Capacitance (per channel) | 1.5pF typical at 10MHz - preserves signal integrity up to 240MHz operation (e.g., USB 2.0 full-speed) |
| Leakage Current | ≤1nA max at VCC = 5.5V - avoids loading precision analog inputs in glucose meters or heart rate monitors |
| Clamp Voltage (IEC ±15kV) | VCC + 100V / –100V at 45A - limits voltage stress on downstream PHY ICs during worst-case air-gap discharge |
| Supply Voltage Range | 0.9V to 5.5V - supports direct integration with 1.8V, 3.3V, and 5V interface rails without level-shifting |
| Peak Pulse Current | 5.5A (8/20µs waveform) - handles surge energy from IEC 61000-4-5 indirect lightning-induced transients |
| Operating Temperature | –40°C to +85°C - qualified for industrial and portable medical device environments |
Pinout & Package
SOT-5X3 (DRL) package: 1.60mm × 1.20mm body, 0.65mm height, 6-pin surface-mount with exposed thermal pad (not electrically connected in DRL variant).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IO1) | ESD-protected I/O channel | First high-speed signal line (e.g., USB D+ or LVDS+); clamped to GND/VCC during transients |
| 2 (IO2) | ESD-protected I/O channel | Second high-speed signal line (e.g., USB D– or LVDS–); shares same low-capacitance protection architecture |
| 3 (GND) | Ground reference | Primary return path for ESD current; must be low-inductance connection to system ground plane |
| 4 (IO3) | ESD-protected I/O channel | Third protected line (e.g., second USB port D–); enables dual-port protection with single device |
| 5 (IO4) | ESD-protected I/O channel | Fourth protected line (e.g., second USB port D+); completes four-channel protection set |
| 6 (VCC) | Power-supply input | Bias reference for clamping network; bypass with 0.1µF ceramic capacitor to GND for effective transient shunting |
Key Features
| Feature | Design Value |
|---|---|
| Uni-directional ESD clamp architecture | Enables precise VCC-referenced clamping without reverse-bias leakage issues common in bi-directional TVS arrays |
| Dual-diode per-line topology | Reduces effective channel capacitance to 1.5pF while maintaining robust ±15kV air-gap protection capability |
| VCC pin with internal clamp | Protects power rail from coupled transients - eliminates need for separate VCC TVS in compact designs |
| Ultra-low leakage current | <1nA max ensures minimal DC error in precision analog front-ends used in medical sensor applications |
| Space-saving DRL package | 1.60mm × 1.20mm footprint allows placement within 2mm of USB/LVDS connectors - critical for ESD energy diversion |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E1U06DBVR | Lower IO capacitance (0.5pF), higher IEC rating (±15kV contact), lower clamping voltage (VCC + 12V), no input capacitor required | Better suited for >1Gbps interfaces (e.g., USB 3.2 Gen 1) and noise-sensitive analog sensors | Select when upgrading from TPD4E001DRLRG4 for higher-speed or lower-clamp-voltage requirements; not pin-compatible with DRL package |
| TPD4E001DCKRG4 | Identical electrical specs; SC-70 (DCK) package (2.00mm × 1.25mm) instead of SOT-5X3 (DRL) | Preferred for designs using SC-70 footprints or requiring slightly larger thermal pad area | Drop-in functional replacement if board layout accommodates SC-70; same 1.5pF/±8kV spec but different land pattern and RθJA (251.1°C/W vs 226.4°C/W) |
Compared with TPD4E001DRLRG4, TPD4E1U06DBVR offers superior high-frequency performance and tighter clamping at the cost of non-pin-compatibility and higher unit price, while TPD4E001DCKRG4 provides identical protection in a mechanically distinct but functionally interchangeable SC-70 package.

FAQ
What is the primary ESD protection standard compliance for TPD4E001DRLRG4?
The TPD4E001DRLRG4 is rated to IEC 61000-4-2 Level 4, providing ±8kV contact discharge and ±15kV air-gap discharge protection across all IO pins. This certification is validated per test conditions in the official Texas Instruments datasheet SLLS682P, making TPD4E001DRLRG4 suitable for end-equipment requiring highest-tier ESD immunity in consumer and industrial applications.
Does TPD4E001DRLRG4 require an external power supply to operate?
No - the TPD4E001DRLRG4 is a passive ESD protection device and does not require active biasing. However, its VCC pin must be connected to the system supply rail (0.9V–5.5V) to enable proper clamping behavior during positive transients. A 0.1µF ceramic capacitor is mandatory between VCC and GND to stabilize the clamp reference during ESD events.
Can TPD4E001DRLRG4 be used to protect bidirectional data lines like USB D+ and D–?
Yes - the TPD4E001DRLRG4's unidirectional architecture with VCC-referenced clamping protects both polarities of differential signals. When IO1 and IO2 are assigned to USB D+ and D–, the device clamps positive excursions above VCC and negative excursions below GND, preserving signal swing integrity while meeting USB-IF ESD test requirements.
What is the maximum operating temperature range specified for TPD4E001DRLRG4?
The TPD4E001DRLRG4 is fully specified from –40°C to +85°C ambient temperature, with thermal metrics including RθJA = 226.4°C/W (DRL package) confirming reliable operation under sustained industrial-grade thermal loads. This range is validated per JEDEC JESD51 standards and applies to all electrical parameters in the datasheet.
Is TPD4E001DRLRG4 pin-compatible with other TPD4E001 variants such as TPD4E001DCKRG4?
No - TPD4E001DRLRG4 uses the SOT-5X3 (DRL) package, while TPD4E001DCKRG4 uses SC-70 (DCK). Though electrically identical, their land patterns, pinouts, and mechanical dimensions differ: DRL has 1.60mm × 1.20mm body with specific pin 1 orientation, whereas DCK measures 2.00mm × 1.25mm and follows SC-70 pin mapping. PCB redesign is required for substitution.
