SMAJ15CA

The "SMAJ15CA from Dearborn" refers to a specific type of transient voltage suppressor (TVS) diode, commonly used in electronic circuits to protect sensitive components from voltage spikes. Here’s a detailed description of its characteristics and features:

Physical Characteristics:

• Package Type: The SMAJ15CA is typically housed in a surface-mount package, which allows for easy integration into printed circuit boards (PCBs). The package is compact, making it suitable for applications where space is limited.
• Dimensions: The dimensions of the SMAJ package are generally around 5.2 mm in length and 3.5 mm in width, with a low profile that helps in maintaining a slim design for electronic devices.

Electrical Specifications:

• Reverse Stand-Off Voltage (V_RWM): The SMAJ15CA has a reverse stand-off voltage of 15 volts, meaning it can withstand this voltage without conducting. This makes it ideal for protecting circuits operating at or below this voltage level.
• Clamping Voltage (V_C): When a transient voltage occurs, the clamping voltage is the maximum voltage that the diode will allow to pass through. For the SMAJ15CA, this is typically around 24 volts, providing a robust level of protection against voltage spikes.
• Peak Power Dissipation: The device can handle peak power dissipation of up to 400 watts for a short duration, which is crucial during transient events like electrostatic discharge (ESD) or lightning strikes.
• Capacitance: The diode has a low capacitance value, which minimizes signal distortion in high-speed applications, making it suitable for data lines and communication circuits.

Performance Characteristics:

• Response Time: The SMAJ15CA has a fast response time, typically in the nanosecond range, allowing it to react quickly to transient events and protect sensitive components effectively.
• Temperature Range: The operating temperature range is usually from -55°C to +150°C, making it suitable for a variety of environments, including automotive and industrial applications.

Applications:

• Consumer Electronics: Commonly used in smartphones, tablets, and other portable devices to protect against ESD and voltage spikes.
• Automotive: Employed in automotive electronics to safeguard sensitive components from transients caused by load dumps or other electrical disturbances.
• Telecommunications: Utilized in communication equipment to protect data lines and ensure signal integrity.

Manufacturer:

• Origin: The "from Dearborn" designation likely refers to the manufacturing location or the company associated with the production of this component, which may be a well-known electronics manufacturer based in Dearborn, Michigan.

In summary, the SMAJ15CA from Dearborn is a reliable and efficient transient voltage suppressor diode designed to protect electronic circuits from voltage spikes, ensuring the longevity and reliability of sensitive components in various applications.
