Product details
Overview
TPD2E001DRST-NM from Texas Instruments is a two-channel uni-directional ESD protection diode array in a 3.00 mm × 3.00 mm non-magnetic WSON (DRS) package, rated for ±8-kV contact and ±15-kV air-gap IEC 61000-4-2 Level 4 ESD suppression, with 1.5 pF typical channel capacitance and 1 nA max leakage - deployed on USB 2.0 D+/D− lines to protect high-speed interface ICs.
For engineers reviewing the TPD2E001DRST-NM datasheet, TPD2E001DRST-NM pinout, TPD2E001DRST-NM application, or TPD2E001DRST-NM equivalent, this page delivers verified electrical parameters, validated DRS-package pin mapping, medical-grade non-magnetic compliance, and direct alternatives for USB 2.0, LVDS, and SVGA video ESD hardening.
Technical Context
The TPD2E001DRST-NM implements a central ESD clamp architecture with two internal diodes per channel tied to VCC, enabling bidirectional transient shunting to GND and VCC during ±15-kV HBM or IEC 61000-4-2 events. Its uni-directional topology supports signal swing up to VCC + 0.95 V forward voltage or up to 10 V when VCC is unconnected but bypassed with 0.1 µF.
It operates across –40°C to +85°C with 0.9 V–5.5 V supply range, draws ≤100 nA supply current, and maintains ≤1 nA channel leakage at full temperature range. The exposed pad (EP) must be soldered to GND for thermal and ESD return path integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating (IEC 61000-4-2) | ±8-kV contact / ±15-kV air-gap - meets Level 4 immunity for consumer/industrial USB ports |
| IO Capacitance | 1.5 pF @ 10 MHz, VCC/2 bias - preserves signal integrity up to 240 MHz USB 2.0 data rates |
| Channel Leakage Current | ≤1 nA over –40°C to +85°C - avoids DC loading on sensitive analog or low-power IO lines |
| Clamp Voltage (IEC ±8-kV) | VCC + 60 V (positive) / –60 V (negative) - limits stress on downstream PHY or controller |
| Supply Voltage Range | 0.9 V to 5.5 V - compatible with 1.8 V, 3.3 V, and 5 V logic domains without level-shifting |
| Operating Temperature | –40°C to +85°C - qualified for industrial and portable medical equipment environments |
| Package | 6-pin WSON (DRS), 3.00 mm × 3.00 mm, non-magnetic - certified for MRI-adjacent glucose meters and imaging systems |
Pinout & Package
TPD2E001DRST-NM uses the non-magnetic 6-pin WSON (DRS) package (3.00 mm × 3.00 mm, 0.6 mm max height) with exposed thermal pad (EP) that must be connected to GND for optimal ESD dissipation and thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 4) | Ground reference | Primary ESD return path; connects internally to EP for low-inductance discharge |
| VCC (Pin 1) | Power-supply input | Bias node for clamp circuit; requires 0.1 µF ceramic bypass to GND even if left floating |
| IO1 (Pin 3) | ESD-protected signal line | Protected channel for USB D−, LVDS−, or SVGA blue; clamps transients to GND/VCC |
| IO2 (Pin 6) | ESD-protected signal line | Protected channel for USB D+, LVDS+, or SVGA green; identical clamping behavior to IO1 |
| N.C. (Pins 2 & 5) | No connection | Not internally bonded - must remain unconnected on PCB; no routing or copper fill required |
Key Features
| Feature | Design Value |
|---|---|
| Non-magnetic WSON package | DRS variant eliminates magnetic interference - certified for use in MRI-adjacent medical imaging and glucose meter PCBs |
| Low 1.5 pF IO capacitance | Minimizes signal rise-time degradation and reflection on 480 Mbps USB 2.0 differential pairs |
| Uni-directional clamp architecture | Enables safe operation with 0–10 V signal swing when VCC is unpowered but bypassed |
| Integrated VCC-to-GND clamp | Protects power rail from coupled ESD energy - eliminates need for separate VBUS TVS in compact USB designs |
| Exposed thermal pad (EP) | Reduces junction-to-board thermal resistance to 64.8°C/W - sustains reliability under repeated ESD stress |

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 SOT-5X3 variant; lower clamping voltage (VCC + 12 V @ ±8-kV), higher IEC rating (±20-kV air), no input capacitor needed | Preferred for space-constrained USB ports where layout area prohibits 0.1 µF VCC bypass capacitor | Select when minimizing BOM count and improving clamping margin outweigh non-magnetic requirement |
| TPD2E001DRSR | Same DRS package, identical electrical specs, but standard (magnetic) NiPdAu lead finish instead of Sn-only non-magnetic finish | Acceptable for non-MRI industrial USB/Ethernet interfaces where magnetic susceptibility is not regulated | Choose for cost-sensitive production where non-magnetic certification is unnecessary |
Compared with TPD2E001DRST-NM, TPD2E2U06DRLR offers superior clamping and eliminates the 0.1 µF capacitor, while TPD2E001DRSR retains identical performance but lacks MRI compatibility - making TPD2E001DRST-NM the sole option for certified non-magnetic medical deployments.

FAQ
What is the primary function of the TPD2E001DRST-NM?
The TPD2E001DRST-NM is a two-channel ESD protection diode array designed to suppress electrostatic discharge transients on high-speed data lines. It routes ±8-kV contact and ±15-kV air-gap ESD strikes to GND and VCC using a central clamp structure, protecting downstream ICs like USB PHYs or LVDS receivers without degrading signal integrity due to its 1.5 pF channel capacitance. Its non-magnetic DRS package ensures safe operation in MRI-adjacent medical devices.
Why does the TPD2E001DRST-NM require a 0.1 µF capacitor on the VCC pin?
The 0.1 µF ceramic capacitor on the VCC pin of the TPD2E001DRST-NM provides a low-impedance path to GND for high-frequency ESD energy coupled onto the VCC rail. Even when VCC is left unconnected to the system supply, this capacitor enables the internal clamp to safely divert transients. Without it, the device's ability to clamp positive transients above VCC + VF is compromised, increasing risk of overstress on protected lines.
Is the TPD2E001DRST-NM pin-compatible with other TPD2E001 variants?
Yes - the TPD2E001DRST-NM shares identical pinout (GND, VCC, IO1, N.C., N.C., IO2) and footprint with all 6-pin DRS-packaged variants including TPD2E001DRSR and TPD2E001DRSRG4. However, only TPD2E001DRST-NM uses Sn-only lead finish to meet non-magnetic requirements for medical imaging; other DRS variants use NiPdAu and are unsuitable for MRI environments.
Can the TPD2E001DRST-NM protect signals beyond 5 V?
Yes - when the VCC pin is left unconnected (but still bypassed with 0.1 µF to GND), the TPD2E001DRST-NM supports signal swings up to 10 V on IO1 and IO2. This mode leverages the device's intrinsic diode breakdown characteristics rather than VCC-referenced clamping, enabling use in legacy 10 V logic or analog video paths where 5 V rails are unavailable.
How does the non-magnetic property of the TPD2E001DRST-NM impact its use in medical devices?
The TPD2E001DRST-NM uses Sn-only terminal finish and non-magnetic mold compound to eliminate ferromagnetic interference, satisfying IEC 60601-2-33 requirements for devices used near MRI scanners. This allows placement on PCBs within 1 meter of MRI bores - critical for glucose meters, portable ultrasound controls, and patient monitors where ESD protection cannot compromise imaging fidelity or safety certifications.
