SMAJ36A

The SMAJ36A is a specific type of transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc. It is designed to protect sensitive electronic components from voltage spikes and transients, which can occur due to various factors such as electrostatic discharge (ESD), lightning strikes, or inductive load switching.

Key Features:

1. Voltage Rating: The SMAJ36A has a breakdown voltage of approximately 36 volts, making it suitable for applications where the maximum operating voltage is around this level. It is important to note that the breakdown voltage is the point at which the diode begins to conduct in reverse, effectively clamping the voltage to protect downstream components.

2. Power Dissipation: This device can handle a peak power dissipation of up to 600 watts for a very short duration (typically 1 ms), which allows it to absorb significant energy from transient events without failing.

3. Package Type: The SMAJ36A is housed in a DO-214AA (SMA) package, which is a surface-mount device (SMD) that is compact and suitable for automated assembly processes. The package dimensions are designed to facilitate efficient thermal management and ensure reliable performance in various environments.

4. Clamping Voltage: The clamping voltage of the SMAJ36A is specified at a certain peak pulse current, which indicates the maximum voltage that will appear across the device during a transient event. This is crucial for ensuring that the voltage does not exceed the maximum ratings of the protected components.

5. Response Time: The SMAJ36A features a fast response time, which is essential for effectively clamping voltage spikes before they can damage sensitive electronics. This rapid response is a key characteristic of TVS diodes.

6. Applications: The SMAJ36A is commonly used in a variety of applications, including telecommunications, automotive electronics, consumer electronics, and industrial equipment. It is particularly useful in protecting data lines, power lines, and other sensitive circuits from overvoltage conditions.

7. Environmental Considerations: The device is designed to operate over a wide temperature range, typically from -55°C to +150°C, making it suitable for use in harsh environments. Additionally, it is compliant with various environmental standards, ensuring its reliability in different applications.

8. RoHS Compliance: The SMAJ36A is RoHS compliant, meaning it is free from hazardous substances and meets environmental regulations, which is increasingly important in modern electronic manufacturing.

Summary:

In summary, the SMAJ36A from Littelfuse Inc. is a robust and reliable transient voltage suppressor diode that provides essential protection for electronic circuits against voltage transients. Its combination of a suitable breakdown voltage, high power dissipation capability, fast response time, and compact packaging makes it an ideal choice for a wide range of applications in today's electronic devices.
