Introduction
In USB, HDMI, CAN/LIN, GPIO, audio, and other high-speed data interfaces, ESD protection devices, though small in size, directly affect the ability of backend ICs to withstand electrostatic discharge and transient overvoltage surges.
TI's ESD protection products have a wide range of applications; however, in addition to meeting electrical performance requirements, lead time, procurement costs, and long-term supply stability are equally important when selecting devices.
In recent years, some electronics manufacturers have faced issues such as extended lead times and price fluctuations during the procurement process. Semiware offers ESD protection devices covering general-purpose interfaces, high-speed data interfaces, and applications such as CAN/LIN, allowing for parameter comparison and alternative evaluation of existing TI ESD part numbers.
I. Differentiated Advantages of Semiware ESD Devices
Addressing the pain points of long lead times, inconsistent pricing, and insufficient performance redundancy currently facing the industry, the Semiware ESD series offers five core advantages compared to traditional TI solutions:
- Stable Supply and Mass Production
- Semiware maintains a stable inventory and mass production capability for mainstream ESD models, providing sample, small-batch, and mass production delivery support based on project requirements.
- Coverage of General-Purpose, High-Speed, and Automotive Interfaces
- Semiware ESD products cover a variety of packages and applications. Some products utilize low capacitance or snap-back technology, suitable for applications with high clamping voltage or signal integrity requirements.
- Low-Capacitance Products Covering High-Speed Interfaces
- Semiware's ultra-low capacitance ESD/PESD products are suitable for high-speed data interfaces sensitive to parasitic capacitance. Specific models need to be matched based on interface speed, operating voltage, circuit structure, and PCB design.
- EMC Testing and Selection Support
- Semiware possesses ESD, surge, and automotive transient testing capabilities, providing device selection and testing support based on customer project requirements. For alternative projects, targeted replacement suggestions can be provided based on the customer's PCB design.
- More Competitive BOM Costs
- Provided that electrical parameters, packaging, and pin configurations meet requirements, Semiware's ESD replacement models can help customers reduce component procurement costs.
- For high-volume products, stable unit prices and predictable delivery cycles also facilitate long-term BOM cost management for the procurement team.

III. Selection and Replacement Recommendations by Application Scenario
TI ESD devices remain a classic industry solution due to their comprehensive certification system and standardized technical documentation. However, due to long-term supply chain instability, global design teams are actively evaluating robust alternatives. For different application scenarios, Semiware replacement selection recommendations are as follows:
- Low-speed interfaces (USB 2.0, GPIO, buttons, audio): Replacement can be directly evaluated. These scenarios are not sensitive to capacitance and signal loss, resulting in extremely low replacement risk and rapid cost optimization.
- High-speed interfaces (USB 3.0/3.1, HDMI): Batch import is recommended after sample testing.
- Ultra-high-speed scenarios (USB4, Thunderbolt, 5G RF): Semiware PESD polymer series is preferred, with ultra-low capacitance as low as 0.05pF, suitable for ultra-high bandwidth transmission requirements.
- CAN/LIN industrial and automotive buses: Reliable for evaluation and replacement; sufficient redundancy in protection parameters, suitable for harsh industrial and automotive conditions.
- Power supply and VBUS protection: No stringent capacitor requirements; Semiware high-power protection devices are mature, stable, and highly adaptable.
Summary
Semiware provides ESD protection devices covering USB, HDMI, GPIO, CAN, LIN, and high-speed data interfaces, and can perform parameter matching and replacement evaluation for specific TI part numbers.
If you are looking for a TI TVS diode alternative, please provide your existing TI part number, BOM, or interface application information.
