The SM712 is a high‑performance transient voltage suppression (TVS) diode array specifically designed for RS‑485 interfaces. Featuring an asymmetrical protection scheme (+12 V to −7 V), it effectively safeguards against transient voltage threats such as electrostatic discharge (ESD), electrical fast transients (EFT), and lightning strikes. Its integrated design and low‑clamping voltage characteristics significantly enhance device reliability, making it well suited for demanding industrial and telecommunications environments.

The ESD150A5FB is a high‑performance bidirectional transient voltage suppressor (TVS) designed to protect sensitive electronic devices from high‑energy transient voltages caused by electrostatic discharge (ESD), electrical fast transients (EFT), and lightning strikes. Housed in an SOD‑323 package, it combines a compact footprint with robust protection, making it ideally suited for space‑constrained, reliability‑critical applications such as mobile phones, portable devices, and in‑vehicle infotainment systems.

The ESD5B series is designed to provide ESD protection for voltage‑sensitive components. Its excellent clamping performance, low leakage current, and fast response time deliver industry‑leading protection for designs exposed to ESD. With its compact size and bidirectional design, it is particularly well suited for cellular phones, MP3 players, and other portable applications that require audio‑line protection.

Typical applications: Smartphones, tablets, and related accessories Laptops, servers, and industrial power modules In-vehicle audio‑video systems (MID/CAR DVD/MP3/MP4) Portable instruments, digital cameras, and smart wearable devices Transient protection for communication interfaces and industrial control systems
