Automotive Uni and Bi-directional ESD Protection Diode

Taiwan Semiconductor Co. Ltd. introduces a series of ultra-small ESD protection devices for wearables and other high-density electronic products. The new TESDAx Series, features proprietary clamping to prevent overvoltage damage from ESD and lightning on control, power lines.

These ultra-small diodes are ideal for safeguarding sensitive electronics in high-density applications like portable medical devices, smart phones, and PDAs. Being AEC-Q101 qualified, the TESDAx Series delivers robust protection to IEC 61000-4-2 (ESD ±30kV air/contact), IEC 61000-4-4 (EFT 40A), and IEC 61000-4-5 (Lightning 5A). Their ultra-small packages are crucial for saving board space, ensuring reliability and superior protection for compact and high-density designs.
