Overview of SMAJ12A-TR by STMicroelectronics
The SMAJ12A-TR from STMicroelectronics is a unidirectional transient voltage suppressor diode, engineered specifically for protecting electronic circuits from voltage spikes. It operates at a reverse voltage of 12 volts and can handle a maximum voltage of up to 400 watts. Positioned within the Transient Suppressors subcategory of diodes, this part is encapsulated in a DO-214AC package, familiar in the industry as an SMA package which features a plastic/epoxy body material ensuring durability and reliability.
The SMAJ12A-TR is designed to clamp excessive transient voltages to a safe level before they can damage sensitive components in electronic circuits. It functions with a minimum breakdown voltage of 13.3 volts and a maximum clamping voltage of 25.3 volts. Its moisture sensitivity level of 1 indicates a high resistance to moisture, which is critical for maintaining performance in varied environmental conditions. Furthermore, the part is RoHS compliant and indicated with an EAR99 ECCN code, which simplifies international trade considerations.
