SMA Diodes for Modern Electronic Applications

P4SMA Series Diodes by TDSEMIC are TVS (Transient Voltage Suppressor) protection components used to safeguard electronic circuits against voltage spikes and electrical disturbances. They are available in unidirectional versions (marked with the letter "A") and bidirectional versions ("CA"), allowing for broad application across various circuits. These diodes come in a DO-214AC (SMA).

Key Features:

• Peak pulse power: 400 W (with a 10/1000 µs waveform).
• Operating voltage range: from 15V to 68V (depending on the model).
• Response time: extremely fast – in the nanosecond range.
• Package: DO-214AC (SMA) – compact, surface-mount.
• Low leakage current: minimal losses under normal operating conditions.
• Available in both unidirectional and bidirectional versions.
• High reliability:  resistant to repetitive voltage pulses.

Applications:

• Telecommunications – protection of transmission lines, modems, and routers.
• Industrial – protection of control and automation systems.
• Computing and peripherals – protection of USB ports, HDMI, and I/O interfaces.
• Automotive – protection of electronic modules in vehicles.
• Consumer electronics – smartphones, tablets, switch-mode power supplies.
• Energy sector – protection in power systems and photovoltaic panels.
