Product Description

The 1SMA5949B TVS Diode, part of the SMAJ5949B Series, is a robust 59V Transient Suppressor designed to protect sensitive electronics from voltage spikes. It features a standoff voltage of 59V and clamps transient voltages to safe levels, supporting peak pulse power handling up to 600W. Operating within a wide temperature range of -55°C to +150°C, this unidirectional diode offers fast response times (nanosecond-level) and is ideal for overvoltage protection in industrial automation, telecom systems, and automotive electronics. Compatible with standard SMA packaging, it integrates seamlessly into circuits requiring surge protection for power lines or communication interfaces like RS-485, CAN, or Ethernet. Advantages include high surge capacity and reliability in harsh environments, while its primary limitation is limited voltage tolerance beyond specified ratings. No battery or display components are included, as it functions purely as a passive protective device.
