SMAJ5.0CA

The SMAJ5.0CA from Dearborn is a robust and reliable transient voltage suppressor (TVS) diode designed to protect sensitive electronic components from voltage spikes and transients. This component is particularly useful in applications where overvoltage protection is critical, such as in automotive, industrial, and consumer electronics.

Physical Characteristics: The SMAJ5.0CA is housed in a DO-214AC (SMA) package, which is a small, surface-mount device that allows for easy integration into circuit boards. The package is typically made of a durable plastic material, providing both mechanical protection and thermal stability. The diode features two leads that extend from the body, allowing for straightforward soldering onto a PCB.

Electrical Specifications:

• Reverse Stand-Off Voltage (V_RWM): The SMAJ5.0CA has a reverse stand-off voltage of 5.0 volts, making it suitable for clamping voltage spikes that exceed this threshold.
• Clamping Voltage (V_C): When subjected to a transient voltage, the clamping voltage is typically around 8.0 volts, ensuring that the voltage does not exceed safe levels for connected components.
• Peak Power Dissipation: The device can handle peak power dissipation of up to 400 watts for a short duration, making it effective in absorbing high-energy transients.
• Operating Temperature Range: The SMAJ5.0CA operates effectively within a temperature range of -55°C to +150°C, allowing it to function in various environmental conditions.

Performance Features: The SMAJ5.0CA is designed for fast response times, which is crucial for protecting sensitive electronics from damage due to voltage spikes. Its low leakage current ensures minimal power loss during normal operation, contributing to overall energy efficiency in the circuit.

Applications: This TVS diode is widely used in applications such as:

• Automotive electronics, where voltage transients can occur due to inductive loads.
• Communication equipment, to protect against lightning strikes and other surges.
• Consumer electronics, safeguarding devices like smartphones and tablets from overvoltage conditions.

Conclusion: The SMAJ5.0CA from Dearborn is a versatile and essential component for any electronic design requiring reliable overvoltage protection. Its combination of compact size, high power handling capability, and effective clamping performance makes it an ideal choice for engineers looking to enhance the durability and reliability of their electronic systems.
