Texas Instruments TPD4EUSB30DQAR ESD Protection Diode, 4-Channel, 8V, 5A, SON
Texas Instruments 4-channel ESD diode, 8V/5A, for USB 3.0. Low 0.7pF capacitance, SON package. Protects computers, consumer electronics & industrial gear.
The Texas Instruments TPD4EUSB30DQAR is a high-performance 4-channel Electrostatic Discharge (ESD) protection device engineered for safeguarding super-speed USB 3.0 interfaces. This robust component is designed to reliably dissipate transient voltage spikes, offering protection up to the maximum level specified by the stringent IEC 61000-4-2 international standard for contact discharge. It also provides a 5A (8/20µs) peak pulse current rating in compliance with the IEC 61000-4-5 surge specification, ensuring resilience against power surges.
A key advantage for high-speed data integrity is its exceptionally low 0.7pF capacitance and 0.6Ω dynamic resistance, which minimises signal degradation and distortion. This makes it perfectly suited for supporting USB 3.0 data rates of up to 5Gbps without compromising performance. The device features a flow-through pin mapping design, which simplifies PCB layout and routing for differential pairs.
With a maximum IO leakage current of just 100nA, it ensures minimal power drain in portable applications. The component operates reliably across a broad industrial temperature range of -40°C to 85°C. Packaged in a space-efficient SON (Small Outline No-Lead) case with 10 pins, it is ideal for compact electronic designs where board space is at a premium.
This ESD protection diode is a critical solution for enhancing the reliability and longevity of sensitive electronic circuits, providing a first line of defence against electrostatic discharge and transient voltage events in demanding environments.
