SMAJ12A General Description

The SMAJ12A is a surface-mount TVS diode, which means it's designed for use in compact and modern electronic circuits. Its primary purpose is to divert excessive voltage away from sensitive components to protect them from voltage surges, such as electrostatic discharge (ESD) or electrical transients caused by events like lightning strikes or inductive load switching.

Key Features

Halogen-Free and RoHS compliant
For surface mounted applications in order to optimize board space
Low profile package
Built-in strain relief
Glass passivated junction
Low Inductance
Excellent clamping capability
Repetition Rate (duty cycle): 0.01%
Fast response time: typically less than 1.0ps from 0 Volts to V(BR) for unidirectional types.
Typical IR less than 1mA above 10V
High temperature soldering: 250 degrees C/10 seconds at terminals
Plastic package has Underwriters Laboratory Flammability 94V-O

Application

Consumer Electronics: TVs, computers, smartphones, and other consumer electronics use TVS diodes to protect against electrostatic discharge and voltage spikes.
Communication Systems: Communication equipment, such as routers, modems, and network switches, use TVS diodes to safeguard against lightning-induced surges or other electrical disturbances.
Automotive Electronics: Vehicles incorporate TVS diodes to protect sensitive electronic systems, such as engine control units (ECUs), from voltage transients caused by load dumps, jump starts, or other factors.
Industrial Control Systems: Automation and industrial control systems use TVS diodes to protect against voltage surges from motors, relays, and other inductive loads.
Power Supplies: Power supply units and voltage regulation circuits often employ TVS diodes to prevent damage due to voltage fluctuations.
Data Centers: Data center equipment and servers use TVS diodes to ensure the reliability and protection of critical infrastructure.
