Product details
Overview
TPD4E004DRYR from Texas Instruments is a 4-channel ESD protection diode array in a 6-pin SON (DRY) package, rated for ±8-kV IEC 61000-4-2 contact discharge, ±12-kV air-gap discharge, and ±15-kV HBM. It delivers 1.6-pF channel input capacitance, 0.9–5.5-V operating voltage range, and ultra-low leakage (<1 nA), making it suitable for USB 2.0, Ethernet, and SVGA video interface protection.
For engineers reviewing the TPD4E004DRYR datasheet, TPD4E004DRYR pinout, TPD4E004DRYR application, or TPD4E004DRYR equivalent, this page provides verified electrical specifications, functional pin mapping, real-world implementation guidance for high-speed data lines, and validated alternative options for ESD protection in space-constrained designs.
Technical Context
The TPD4E004DRYR implements a quad-channel TVS architecture with bidirectional clamping diodes per channel-each steers ESD transients to VCC or GND depending on polarity. Its monolithic silicon design ensures tight capacitance matching (<0.4 pF variation) across all four IO pins, critical for signal integrity in differential high-speed interfaces like USB D+/D−.
It operates passively without bias current draw during normal conditions (ICC = 500 nA max), triggering only when IO voltage exceeds ±6 V breakdown or drops below –0.3 V, clamping transient energy within nanoseconds. The VCC pin supports two configurations: connected to system rail for clamping above VCC + VF, or left floating for extended 0–5.8 V signal swing tolerance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating (IEC 61000-4-2) | ±8-kV contact / ±12-kV air-gap - meets IEC Level 3 for robust system-level ESD immunity |
| ESD Rating (HBM) | ±15-kV - protects against human-body discharge events common in handheld device handling |
| Channel Input Capacitance | 1.6 pF @ 10 MHz, VCC = 5 V - preserves signal integrity up to 240 MHz (USB 2.0 full-speed) |
| Breakdown Voltage (VBR) | 6–8 V @ 10 µA - defines precise clamping threshold to avoid false triggering during normal operation |
| Leakage Current (II) | ±1 nA max @ VIO = 2.5 V - prevents loading of sensitive analog or low-power digital receivers |
| Operating Voltage Range | 0.9–5.5 V on VCC - compatible with 1.8-V, 3.3-V, and 5-V interface rails without level-shifting |
| Junction Temperature Range | –40°C to +85°C - qualified for industrial and consumer portable electronics environments |
Pinout & Package
TPD4E004DRYR uses a 6-pin SON (Small Outline No-lead) package designated DRY, measuring 1.45 mm × 1.0 mm × 0.6 mm max height. The exposed pad enhances thermal dissipation and must be soldered to PCB ground for optimal ESD performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IO1 | Input/Output | ESD-protected signal line (e.g., USB D+); connects directly to connector pin |
| IO2 | Input/Output | ESD-protected signal line (e.g., USB D−); independent clamping path per channel |
| GND | Ground | Primary return path for negative ESD transients; ties to system ground plane |
| IO3 | Input/Output | ESD-protected signal line (e.g., Ethernet TX+); identical electrical behavior to IO1/IO2 |
| IO4 | Input/Output | ESD-protected signal line (e.g., SVGA R/G/B); supports single-ended or differential use |
| VCC | Power Supply | Bias rail for upper-clamp diode; may be tied to system VCC or left floating for wider voltage swing |
Key Features
| Feature | Design Value |
|---|---|
| Low Channel Capacitance | 1.6 pF enables minimal signal distortion on USB 2.0, FireWire, and SVGA video lines |
| Quad-Channel Integration | Four independent ESD paths in one 1.45 mm × 1 mm footprint-reduces board area vs discrete diodes |
| VCC-Configurable Clamping | Supports both powered (VCC-connected) and unpowered (VCC-floating) modes for flexible system integration |
| Tight Capacitance Matching | <0.4 pF inter-channel variation preserves skew-critical timing in differential pairs |
| Ultra-Low Leakage | <1 nA at 2.5 V avoids DC loading of precision analog inputs or battery-powered sensors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E05U06DQAR | Lower 0.5-pF capacitance, ±12-kV contact/±15-kV air-gap, same 6-pin X2SON package | Better suited for USB 3.0/PCIe Gen1 where sub-0.6-pF loading is mandatory | Select when upgrading to higher-speed interfaces; requires layout review due to tighter trace routing constraints |
| SZ1.8SMCG-TP | Single-channel SOD-323, ±15-kV HBM, 12-pF capacitance, no VCC pin | Requires four discrete placements; higher capacitance limits use to low-speed UART or GPIO | Choose only for cost-sensitive, non-high-speed designs where board area is not constrained |
Compared with TPD4E004DRYR, TPD4E05U06DQAR offers superior high-frequency performance but narrower voltage margin (0.6–5.5 V), while SZ1.8SMCG-TP lacks integrated multi-channel coordination and introduces significant signal degradation above 10 MHz-making TPD4E004DRYR the optimal balance of speed, integration, and design simplicity for USB/Ethernet/SVGA.

FAQ
What is the maximum operating temperature for TPD4E004DRYR?
The TPD4E004DRYR is specified for continuous operation from –40°C to +85°C ambient temperature. Its junction temperature must not exceed 150°C under transient ESD stress, and thermal resistance values (RθJA = 414.8°C/W) confirm safe operation in typical PCB layouts with adequate copper pour. Derating is not required within the full industrial temperature range.
Does TPD4E004DRYR require an external capacitor on the VCC pin?
Yes-a 0.1-µF ceramic capacitor is recommended directly between VCC and GND, placed as close as possible to the TPD4E004DRYR package. This capacitor stabilizes the VCC rail during ESD events, preventing voltage sag that could compromise upper-diode clamping performance and ensuring consistent ±8-kV contact discharge protection.
Can TPD4E004DRYR protect USB 3.0 SuperSpeed lines?
No-TPD4E004DRYR is not suitable for USB 3.0 SuperSpeed (5 Gbps) differential pairs due to its 1.6-pF channel capacitance, which exceeds the <0.3-pF requirement for minimal insertion loss at 2.5 GHz. It is fully qualified for USB 2.0 (480 Mbps) and lower-speed interfaces like USB 1.1, UART, or I²C where bandwidth demands are ≤240 MHz.
How does TPD4E004DRYR handle bidirectional signal lines like USB D+ and D−?
TPD4E004DRYR uses back-to-back diode pairs per channel: one diode clamps positive transients to VCC, the other clamps negative transients to GND. This symmetric structure allows uninterrupted bidirectional data flow on lines such as USB D+/D−, Ethernet TX+/TX−, or SVGA RGB, with no DC blocking or signal polarity dependence-preserving full-duplex functionality.
Is the exposed thermal pad on the TPD4E004DRYR package required to be grounded?
Yes-the exposed pad (EP) on the underside of the TPD4E004DRYR's SON package must be soldered to a dedicated PCB ground plane. This connection serves dual purposes: it improves thermal dissipation during ESD events and provides a low-inductance return path for transient currents, reducing clamping voltage overshoot and enhancing overall protection effectiveness.
