SMBJ36CA

The SMBJ36CA is a specific type of transient voltage suppressor (TVS) diode manufactured by FTR (Fujitsu Component Limited). This component is designed to protect sensitive electronic devices from voltage spikes and transients, which can occur due to various factors such as lightning strikes, electrostatic discharge (ESD), or power surges.

Key Features and Specifications:

1. Voltage Rating: The SMBJ36CA is rated for a breakdown voltage of approximately 36 volts. This means it will start to conduct and clamp the voltage when it exceeds this threshold, protecting downstream components.

2. Power Dissipation: The device typically has a power dissipation rating of around 600 watts, which indicates its ability to handle high-energy transients without failing.

3. Package Type: The SMBJ36CA is housed in a DO-214AA (SMB) package, which is a surface-mount device (SMD) that is compact and suitable for various PCB layouts. The package dimensions are approximately 5.2 mm x 3.5 mm x 1.5 mm, making it easy to integrate into space-constrained designs.

4. Clamping Voltage: The clamping voltage is an important specification, as it indicates the maximum voltage that the device will allow to pass through during a transient event. For the SMBJ36CA, this value is typically around 55 volts, ensuring that connected components are protected from excessive voltage.

5. Reverse Stand-off Voltage: The reverse stand-off voltage is the maximum voltage that can be applied to the device without it conducting. For the SMBJ36CA, this is around 36 volts, making it suitable for applications where the normal operating voltage is below this threshold.

6. Response Time: The SMBJ36CA has a fast response time, typically in the nanosecond range, allowing it to react quickly to transient events and minimize the risk of damage to sensitive components.

7. Applications: This TVS diode is commonly used in various applications, including telecommunications, consumer electronics, automotive electronics, and industrial equipment. It is particularly useful in protecting data lines, power lines, and sensitive microcontrollers.

8. Temperature Range: The operating temperature range for the SMBJ36CA is generally from -55°C to +150°C, making it suitable for a wide range of environmental conditions.

9. RoHS Compliance: The SMBJ36CA is often compliant with RoHS (Restriction of Hazardous Substances) regulations, ensuring that it is free from certain harmful materials, which is important for environmentally conscious designs.

Conclusion:

The SMBJ36CA from FTR is a robust and reliable transient voltage suppressor diode that provides essential protection for electronic circuits against voltage spikes. Its compact size, high power handling capability, and fast response time make it an ideal choice for a variety of applications where voltage transients can pose a risk to sensitive components.
