SMBJ36CA

The SMBJ36CA is a transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed to protect sensitive electronic components from voltage spikes and transients. This device is particularly useful in applications where overvoltage protection is critical, such as in telecommunications, automotive electronics, and consumer electronics.

Key Features:

1. Voltage Rating: The SMBJ36CA is rated for a breakdown voltage of approximately 36 volts, making it suitable for clamping voltage transients that exceed this level. It is designed to handle both positive and negative transients.

2. Power Dissipation: The device can handle a peak power dissipation of up to 600 watts, which allows it to absorb significant energy from voltage spikes without failing.

3. Package Type: The SMBJ36CA is housed in a DO-214AA (SMB) package, which is a surface-mount device (SMD) that provides a compact footprint. This package is designed for efficient thermal management and is suitable for automated assembly processes.

4. Clamping Voltage: The clamping voltage is specified at a certain peak pulse current, ensuring that the device will limit the voltage to a safe level during transient events. This is crucial for protecting downstream components.

5. Response Time: The SMBJ36CA has a fast response time, typically in the nanosecond range, allowing it to react quickly to voltage spikes and provide immediate protection.

6. Operating Temperature Range: The device operates effectively over a wide temperature range, typically from -55°C to +150°C, making it suitable for various environmental conditions.

7. Low Leakage Current: The SMBJ36CA features low leakage current under normal operating conditions, which helps to minimize power loss and improve overall system efficiency.

8. Applications: Common applications for the SMBJ36CA include ESD protection, surge protection in power supplies, and safeguarding sensitive components in automotive and industrial electronics.

Electrical Characteristics:

• Reverse Stand-off Voltage (V_R): 36V
• Breakdown Voltage (V_BR): Typically around 40V
• Clamping Voltage (V_C): Specified at a given peak pulse current
• Peak Pulse Power (P_PP): 600W (for 8/20μs waveform)
• Capacitance: Low capacitance values, ensuring minimal impact on signal integrity in high-speed applications.

Conclusion:

The SMBJ36CA from Littelfuse Inc. is a robust and reliable transient voltage suppressor that provides essential protection for electronic circuits against voltage transients. Its combination of high power handling, fast response time, and compact packaging makes it an ideal choice for a wide range of applications where overvoltage protection is necessary.
