The PSM712 from Texas Instruments is an asymmetrical transient voltage suppressor (TVS) array specifically engineered for RS-485 applications. This device provides robust protection against electrostatic discharge (ESD), tertiary lightning, and switching transients, ensuring the reliability of sensitive data lines.
With a peak pulse power rating of 600 Watts for an 8/20µs waveshape, the PSM712 effectively handles transient voltage events. It meets stringent industry standards, including IEC 61000-4-2 (ESD) with levels of Air 15kV and Contact 8kV, IEC 61000-4-4 (EFT) at 40A (5/50ns), and IEC 61000-4-5 (Surge) at 24A (8/20µs).
The device is housed in a compact JEDEC SOT-23 molded package, suitable for surface mount applications. Its operating temperature range is -55°C to 150°C, and it features lead-free pure-tin plating. The PSM712 is RoHS and REACH compliant.
Key applications include RS-485 transceivers, network interfaces, wireless systems, and portable electronics where robust transient voltage protection is critical.
