Product details
Overview
TPD2E001DRLRG4 from Texas Instruments is a 2-channel unidirectional ESD protection diode array in SOT-5X3 (DRL) package, designed for high-speed data interfaces. It delivers ±8-kV contact / ±15-kV air-gap IEC 61000-4-2 Level 4 ESD protection, 1.5-pF typical IO capacitance, and operates across 0.9 V to 5.5 V supply range-ideal for USB 2.0 D+/D− line protection.
For engineers reviewing the TPD2E001DRLRG4 datasheet, TPD2E001DRLRG4 pinout, TPD2E001DRLRG4 application, or TPD2E001DRLRG4 equivalent, key selection criteria include low-capacitance signal integrity preservation, VCC-referenced clamping architecture, dual-channel independent protection, and compatibility with 240-MHz USB 2.0 signaling without signal degradation.
Technical Context
The TPD2E001DRLRG4 implements a central ESD clamp topology with two internal diodes per channel, referenced to both GND and VCC. Its uni-directional structure provides forward conduction above VCC + VF and reverse conduction below GND, enabling robust bidirectional transient suppression on IO lines while maintaining low dynamic impedance during ESD events.
It functions as a passive, voltage-triggered device with 11-V breakdown voltage (IBR = 10 mA), clamping voltages of VCC + 25 V (positive) and –25 V (negative) under ±15-kV HBM, and leakage current ≤1 nA across –40°C to 85°C. No external bias or enable control is required-operation is fully automatic upon overvoltage detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating (IEC 61000-4-2) | ±8-kV contact / ±15-kV air-gap discharge-meets Level 4 industrial immunity requirements. |
| IO Capacitance | 1.5 pF at 10 MHz, VCC = 5 V-minimizes signal distortion on USB 2.0 (480 Mbps) and LVDS links. |
| Supply Voltage Range | 0.9 V to 5.5 V on VCC pin-supports single-supply operation across logic families including 1.8 V, 3.3 V, and 5 V systems. |
| Channel Leakage Current | ≤1 nA at VIO = 0 V to VCC-prevents DC loading on sensitive analog or high-impedance data lines. |
| Breakdown Voltage (VBR) | 11 V at IBR = 10 mA-ensures reliable triggering only during ESD transients, not during normal signal swing. |
| Clamp Voltage (VC) | VCC + 25 V (positive) / –25 V (negative) at 10 A-limits stress on downstream USB transceivers during ±15-kV HBM events. |
| Operating Temperature | –40°C to +85°C-validated for industrial and medical embedded environments. |
Pinout & Package
SOT-5X3 (DRL) package: 5-pin, 1.60 mm × 1.20 mm body, 0.6-mm max height, exposed pad (EP) connected to GND. Compatible with standard reflow profiles (MSL Level-1, 260°C peak).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VCC) | Power-supply reference input | Connects to system VCC rail; enables VCC-referenced clamping; requires 0.1-μF ceramic bypass capacitor to GND. |
| 2 (N.C.) | No internal connection | Not bonded; must be left floating or tied to GND-no electrical function. |
| 3 (IO1) | ESD-protected signal channel 1 | Protects first high-speed line (e.g., USB D+); supports 0–VCC or 0–10 V swing depending on VCC connection. |
| 4 (GND) | Ground reference | Primary return path for ESD current; must be low-inductance connection to system ground plane. |
| 5 (IO2) | ESD-protected signal channel 2 | Protects second high-speed line (e.g., USB D−); electrically isolated from IO1; same specs as IO1. |
Key Features
| Feature | Design Value |
|---|---|
| Uni-directional clamping architecture | Enables precise VCC-referenced protection without false triggering during normal 0–VCC signal transitions. |
| Central ESD clamp with dual-diode per channel | Reduces parasitic capacitance to 1.5 pF while maintaining low dynamic resistance (<1 Ω) during 10-A ESD pulses. |
| VCC pin functionality | Allows flexible implementation: tied to rail for 0–VCC protection, or floated with 0.1-μF cap for 0–10 V tolerance-no redesign needed. |
| Low leakage & supply current | ≤1 nA total ICC and IIO ensures compatibility with battery-powered glucose meters and portable medical devices. |
| Medical imaging qualified variant | DRS-package version (TPD2E001DRST-NM) offers non-magnetic construction-TPD2E001DRLRG4 is not rated for MRI environments. |
Applications
| USB 2.0 Interface Protection | Ethernet PHY Line Protection |
|---|---|
Use Scenario: Protecting D+ and D− pins of a Type-A or Micro-B USB 2.0 connector against user-handling ESD events in portable test equipment.

IC Role / Device Role / Timing Role: Bidirectional ESD clamp on each pair, leveraging VCC reference to maintain common-mode noise rejection during fast transients. Use Value: Sub-2-pF loading avoids signal rise-time degradation; ±8-kV contact rating exceeds EN 61000-4-2 requirements for factory-floor deployment. |
| LVDS Display Interface | Medical Glucose Meter Data Port |
Use Scenario: Shielding 3.3-V LVDS clock/data pairs driving an SVGA panel in kiosk displays subject to frequent operator contact. IC Role / Device Role / Timing Role: Low-capacitance TVS array on each LVDS lane, minimizing jitter accumulation and maintaining >300-Mbps timing margin. Use Value: 1.5-pF IO capacitance prevents >1% duty-cycle distortion at 350 MHz; leakage <1 nA avoids sensor bias drift. | Use Scenario: ESD hardening of UART or custom 2-wire interface between disposable glucose test strip reader and host MCU. IC Role / Device Role / Timing Role: Dual-channel protector on TX/RX lines, operating from 1.8-V MCU I/O with no additional level-shifting. Use Value: 0.9–5.5-V supply range matches ultra-low-power microcontrollers; 1-nA leakage preserves battery life in 5-year shelf-life devices. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E2U06DRLR | Pin-to-pin compatible; lower clamping voltage (VCC + 12 V), higher IEC rating (±20-kV contact), eliminates need for external 0.1-μF VCC capacitor. | Preferred for next-gen USB-C or high-reliability industrial designs where tighter voltage clamping and reduced BOM count are critical. | Select TPD2E2U06DRLR when upgrading from TPD2E001DRLRG4 for enhanced surge margin and simplified layout. |
| ESD5V3U2U-2/TR | 2-channel, 5.3-V standoff, 1.2-pF capacitance, but unidirectional only on IO lines (no VCC clamp); different pinout (SOT-23-6). | Better suited for space-constrained 1.8-V IoT sensor nodes where ultra-low capacitance outweighs VCC clamping need. | Choose ESD5V3U2U-2/TR only if VCC line protection is unnecessary and board area is premium-requires PCB redesign. |
Compared with TPD2E001DRLRG4, TPD2E2U06DRLR improves clamping performance and removes a passive component, while ESD5V3U2U-2/TR trades VCC clamping capability for slightly lower capacitance and incompatible pin mapping-neither is drop-in; layout and validation effort varies by alternative.

FAQ
What is the primary circuit role of the TPD2E001DRLRG4 in a USB 2.0 design?
The TPD2E001DRLRG4 serves as a dual-channel ESD transient voltage suppressor placed directly at the USB connector to shunt ±15-kV IEC 61000-4-2 discharges away from the USB transceiver. Its 1.5-pF IO capacitance ensures minimal impact on 480-Mbps signal integrity, and its VCC-referenced clamping architecture protects both D+ and D− lines while referencing the system power rail-making it integral to robust USB 2.0 interface hardening in TPD2E001DRLRG4-based designs.
Does the TPD2E001DRLRG4 require an external capacitor on the VCC pin?
Yes-the TPD2E001DRLRG4 datasheet specifies a 0.1-μF ceramic capacitor between VCC and GND for effective ESD bypass. This capacitor stabilizes the VCC reference during fast transients and ensures consistent clamping behavior. Omitting it may result in elevated clamp voltage or inconsistent protection performance, especially under ±15-kV air-gap discharge conditions. The capacitor must be placed as close as possible to the VCC and GND pins of the TPD2E001DRLRG4.
Can the TPD2E001DRLRG4 protect signals beyond the 0–5.5 V range?
When the VCC pin is left unconnected (floating) and bypassed with a 0.1-μF capacitor to GND, the TPD2E001DRLRG4 supports signal swings up to 10 V on IO1 and IO2-verified in the datasheet's "Signal Range on IO1 and IO2" section. However, this mode disables VCC-line protection and increases positive clamp voltage. For standard 0–5.5 V operation (e.g., USB 2.0), VCC must be tied to the system supply. The TPD2E001DRLRG4 does not support negative signal excursions below GND.
How does the TPD2E001DRLRG4 differ from the automotive-grade TPD2E001-Q1?
The TPD2E001-Q1 is AEC-Q100 qualified for automotive applications, featuring extended temperature range (–40°C to +125°C), enhanced reliability testing, and zero-defect manufacturing controls. The TPD2E001DRLRG4 is rated for –40°C to +85°C and intended for industrial, medical, and consumer applications. Both share identical electrical specs, pinout, and package-but only TPD2E001-Q1 meets automotive qualification requirements. TPD2E001DRLRG4 is not suitable for under-hood or ADAS systems.
Is the TPD2E001DRLRG4 compatible with lead-free reflow processes?
Yes-the TPD2E001DRLRG4 carries MSL Level-1 rating with peak reflow temperature of 260°C, fully compliant with IPC/JEDEC J-STD-020 lead-free soldering standards. Its SOT-5X3 (DRL) package uses NiPdAu lead finish and is qualified for standard Pb-free reflow profiles. Board assembly must follow TI's recommended thermal profile, including ramp rates and time-above-liquidus, to ensure solder joint integrity and avoid package damage during TPD2E001DRLRG4 mounting.
