SMBJ36CA

The SMBJ36CA is a transient voltage suppressor (TVS) diode manufactured by SINO-IC, designed to protect sensitive electronic components from voltage spikes and transients. Here’s a detailed description of its features and specifications:

General Overview:

• Type: Transient Voltage Suppressor (TVS) Diode
• Package: Typically available in a DO-214AA (SMB) package, which is a surface-mount device (SMD) that is compact and suitable for various PCB layouts.

Electrical Characteristics:

• Reverse Stand-Off Voltage (V_RWM): The SMBJ36CA has a reverse stand-off voltage of 36V, meaning it can withstand this voltage without conducting.
• Clamping Voltage (V_C): When subjected to a transient voltage, the clamping voltage is typically around 55V, which is the maximum voltage the device will allow to pass through during a surge event.
• Peak Power Dissipation: The device can handle peak power dissipation of up to 600W for a duration of 1ms, making it suitable for protecting against high-energy transients.
• Breakdown Voltage (V_BR): The breakdown voltage is specified at approximately 40V, which is the voltage at which the diode begins to conduct significantly.

Performance Features:

• Low Leakage Current: The SMBJ36CA exhibits low leakage current, ensuring minimal power loss during normal operation.
• Fast Response Time: The device is designed to respond quickly to voltage spikes, providing effective protection for sensitive components.
• Bidirectional Protection: This TVS diode is bidirectional, meaning it can protect against transients in both polarities, making it versatile for various applications.

Applications:

• Electronics Protection: Commonly used in consumer electronics, telecommunications, automotive electronics, and industrial equipment to safeguard against ESD (electrostatic discharge) and other voltage transients.
• Data Line Protection: Suitable for protecting data lines and signal lines in communication devices, ensuring signal integrity during transient events.

Mechanical Characteristics:

• Operating Temperature Range: The SMBJ36CA typically operates within a temperature range of -55°C to +150°C, making it suitable for a wide range of environmental conditions.
• Moisture Sensitivity Level (MSL): The device is often rated at MSL 1, indicating it is not sensitive to moisture and can be handled without special precautions.

Conclusion:

The SMBJ36CA from SINO-IC is a robust and reliable transient voltage suppressor diode, ideal for protecting sensitive electronic circuits from voltage spikes. Its combination of high power handling capability, low leakage, and fast response time makes it a preferred choice for engineers looking to enhance the reliability and longevity of their electronic designs.
