Product details
Overview
TPD4E004DRYRG4 from Texas Instruments is a 4-channel ESD protection diode array in a 6-pin SON (DRY) package, designed for high-speed data interfaces. It delivers ±8-kV IEC 61000-4-2 contact discharge and ±12-kV air-gap discharge protection, with 1.6-pF per-channel input capacitance and operation across 0.9 V to 5.5 V supply voltage - enabling robust USB 2.0 and Ethernet signal-line protection without signal integrity degradation.
For engineers reviewing the TPD4E004DRYRG4 datasheet, TPD4E004DRYRG4 pinout, TPD4E004DRYRG4 application, or TPD4E004DRYRG4 equivalent, key selection criteria include channel count, clamping voltage under ±8-kV ESD stress, thermal resistance (RθJA = 414.8°C/W), leakage current (<±1 nA), and compatibility with space-constrained layouts requiring sub-1.5 mm × 1.0 mm footprint.
Technical Context
The TPD4E004DRYRG4 implements a monolithic quad-diode architecture where each IO pin connects to both VCC and GND via low-capacitance steering diodes, enabling bidirectional ESD current diversion during transients. Its functional mode is passive: it remains high-impedance until voltage exceeds ±6 V breakdown (VBR) or drops below –0.3 V, then clamps within nanoseconds.
It operates over –40°C to +85°C ambient temperature and supports two VCC connection modes: tied to system rail (for clamping above VCC + VF) or left floating (enabling up to 5.8 V signal swing). The 0.1-μF bypass capacitor on VCC is mandatory for effective energy shunting during 15–30 A ESD pulses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Contact Discharge | ±8 kV per IEC 61000-4-2 Level 3 - ensures immunity to direct human touch events on exposed ports |
| ESD Air-Gap Discharge | ±12 kV per IEC 61000-4-2 - protects against non-contact electrostatic discharges near connectors |
| Channel Input Capacitance | 1.6 pF at 10 MHz and VCC = 5 V - preserves signal integrity up to 240 MHz (USB 2.0 full-speed) |
| Supply Voltage Range | 0.9 V to 5.5 V on VCC pin - supports single-rail operation across logic families from 1.2 V to 5 V systems |
| Breakdown Voltage (VBR) | 6 V (min) to 8 V (max) at 10 μA - defines precise clamping threshold before diode conduction begins |
| Leakage Current (II) | ±1 nA max at rated operating voltage - prevents DC loading of high-impedance signal lines |
| Junction-to-Ambient RθJA | 414.8°C/W - informs thermal derating requirements for sustained surge conditions in compact PCB layouts |
Pinout & Package
TPD4E004DRYRG4 uses a 6-pin SON (Small Outline No-Lead) package designated DRY, measuring 1.45 mm × 1.0 mm with maximum height of 0.6 mm - optimized for ultra-dense routing near USB/Ethernet connectors.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IO1 | Input/Output | ESD-protected signal line 1 - connects directly to D+, USB2.0, or differential pair leg |
| IO2 | Input/Output | ESD-protected signal line 2 - used for D–, RX, or second high-speed data path |
| GND | Ground | Low-inductance return path for ESD current - must connect to solid ground plane with minimal trace length |
| IO3 | Input/Output | ESD-protected signal line 3 - supports auxiliary interface like VBUS sense or sideband signal |
| IO4 | Input/Output | ESD-protected signal line 4 - enables four independent protected lines in one footprint |
| VCC | Power Supply | Bias rail for upper-clamp diodes - requires 0.1-μF ceramic capacitor placed adjacent to pin for transient suppression |
Key Features
| Feature | Design Value |
|---|---|
| IEC 61000-4-2 Level 3 Compliance | Validated ±8-kV contact / ±12-kV air-gap ESD immunity - meets industrial and consumer end-equipment certification requirements |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E001DRYR | Lower ESD rating: ±4-kV contact / ±8-kV air-gap; same 1.6-pF capacitance and DRY package | Suitable only for less demanding environments (e.g., internal board-to-board links), not external ports | Select when cost sensitivity outweighs need for full IEC Level 3 compliance. |
| SZ1.5SMC15AT3G | Single-channel, higher capacitance (15 pF), higher clamping voltage (>25 V), DO-214AB package | Used for power-rail or low-speed signal protection - incompatible with USB/Ethernet due to bandwidth limitation | Choose only for non-high-speed applications where board space and capacitance are secondary concerns. |
Compared with TPD4E004DRYRG4, TPD4E001DRYR offers reduced ESD margin but identical form factor and capacitance, whereas SZ1.5SMC15AT3G provides higher surge handling at the expense of speed and integration - making TPD4E004DRYRG4 the sole option meeting USB 2.0 timing, size, and IEC 61000-4-2 Level 3 simultaneously.

FAQ
What is the maximum operating temperature range for TPD4E004DRYRG4?
The TPD4E004DRYRG4 is specified to operate across an ambient temperature range of –40°C to +85°C. This range is validated per JEDEC JESD22-A104 for temperature cycling and supported by thermal metrics including RθJA = 414.8°C/W. Operation outside this range may compromise ESD clamping performance or accelerate parametric drift, especially in high-humidity environments.
Does TPD4E004DRYRG4 require an external power supply to function?
No, the TPD4E004DRYRG4 is a passive ESD protection device and does not require active biasing to perform its core clamping function. However, the VCC pin must be connected - either to the system supply rail (for clamping above VCC + VF) or left floating (to allow up to 5.8 V signal swing). A 0.1-μF ceramic capacitor is mandatory at the VCC pin regardless of connection method to ensure effective ESD energy dissipation.
Can TPD4E004DRYRG4 be used for HDMI or PCIe interface protection?
No, the TPD4E004DRYRG4 is not recommended for HDMI or PCIe interfaces. While its 1.6-pF capacitance is suitable for USB 2.0 (480 Mbps) and 100BASE-TX Ethernet (125 MHz), HDMI 1.4+ (up to 3.4 Gbps) and PCIe Gen2+ (2.5–5 GT/s) demand sub-0.5-pF loading and stricter return-loss specifications. TI's TPD4E05U06 or TPD6S300 families are engineered for those higher-bandwidth applications.
What is the clamping voltage of TPD4E004DRYRG4 under an 8-kV IEC 61000-4-2 contact discharge event?
Under an +8-kV IEC 61000-4-2 contact discharge test, the TPD4E004DRYRG4 clamps the protected line to approximately 12 V peak, as measured in Figure 8-2 of the official datasheet (SLVS729C). This clamping voltage is achieved within tens of nanoseconds and remains stable across –40°C to +85°C ambient, ensuring downstream ICs see voltage stress well below their absolute maximum ratings.
Is TPD4E004DRYRG4 compatible with lead-free reflow processes?
Yes, TPD4E004DRYRG4 is RoHS-compliant and qualified for lead-free reflow with a moisture sensitivity level (MSL) rating of Level-1 at 260°C peak. Its NIPDAU (nickel-palladium-gold) terminal finish and SON package support standard JEDEC J-STD-020 profiles. The device has been validated for reflow cycles up to three times without degradation in ESD performance or solder joint integrity.
