SMBJ36A

The SMBJ36A 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 SMBJ36A has a breakdown voltage of approximately 36 volts, making it suitable for clamping voltage transients that exceed this level. Its reverse standoff voltage is typically around 32 volts, allowing it to operate safely under normal conditions without conducting.

2. Power Dissipation: The device is capable of handling a peak power dissipation of up to 600 watts for a short duration (typically 8/20 µs pulse). This high power rating ensures that it can absorb significant energy from voltage spikes without failing.

3. Package Type: The SMBJ36A is housed in a DO-214AA (SMB) package, which is a surface-mount device (SMD) configuration. This package is compact and designed for efficient thermal management, making it suitable for high-density circuit board layouts.

4. Clamping Voltage: During a transient event, the SMBJ36A clamps the voltage to a safe level, typically around 50 volts, which protects downstream components from damage. This clamping action is crucial in safeguarding sensitive ICs and other electronic parts.

5. Response Time: The SMBJ36A features a fast response time, which is essential for effectively mitigating voltage spikes. This rapid response helps to minimize the risk of damage to connected devices.

6. Temperature Range: The operating temperature range for the SMBJ36A is typically from -55°C to +150°C, allowing it to function reliably in a variety of environmental conditions.

7. Applications: Common applications for the SMBJ36A include ESD protection, surge protection in power lines, and safeguarding data lines in communication equipment. It is also used in automotive applications to protect against load dump and other transient events.

8. Compliance and Standards: The SMBJ36A is compliant with various industry standards, ensuring its reliability and performance in critical applications. It may also meet specific regulatory requirements for electronic components.

Summary:

In summary, the SMBJ36A from Littelfuse Inc. is a robust and reliable transient voltage suppressor diode that provides essential protection for electronic circuits against voltage transients. Its high power handling capability, compact package, and fast response time make it an ideal choice for a wide range of applications where overvoltage protection is necessary.
