SMAJ16A

The SMAJ16A 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 automotive, telecommunications, and consumer electronics.

Key Features:

1. Voltage Rating: The SMAJ16A has a breakdown voltage of approximately 16 volts, making it suitable for clamping voltage transients that exceed this threshold. Its reverse standoff voltage is typically around 14.4 volts, allowing it to operate safely under normal conditions.

2. Power Dissipation: The device can handle a peak power dissipation of up to 400 watts for a short duration, which is essential for absorbing high-energy transients without failing.

3. Package Type: The SMAJ16A is housed in a DO-214AA (SMA) package, which is a surface-mount device (SMD) that provides a compact footprint. This makes it ideal for space-constrained applications while ensuring efficient thermal management.

4. Response Time: The SMAJ16A features a fast response time, typically in the nanosecond range, allowing it to react quickly to voltage spikes and protect downstream components effectively.

5. Clamping Voltage: The clamping voltage during a transient event is specified to be around 24 volts, which helps to limit the voltage seen by sensitive components to safe levels.

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

7. Applications: Common applications for the SMAJ16A include ESD protection, surge protection in power lines, and safeguarding sensitive ICs in automotive and industrial environments.

8. Compliance and Standards: The SMAJ16A is compliant with various industry standards, ensuring it meets the necessary safety and performance criteria for electronic components.

Summary:

The SMAJ16A from Littelfuse Inc. is a robust and reliable transient voltage suppressor diode that provides essential protection for electronic circuits against voltage spikes. Its combination of a suitable breakdown voltage, high power dissipation capability, and compact packaging makes it an excellent choice for a wide range of applications requiring overvoltage protection.
