SMDJ33A

The SMDJ33A is a surface-mount 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 SMDJ33A has a breakdown voltage of approximately 33 volts, making it suitable for clamping voltage spikes that exceed this threshold while allowing normal operation below it.

2. Power Dissipation: This device can handle a peak power dissipation of up to 600 watts, which is crucial for absorbing high-energy transients without sustaining damage.

3. Package Type: The SMDJ33A is housed in a DO-214AA (SMB) package, which is a compact, surface-mount design that facilitates easy integration into printed circuit boards (PCBs). The small footprint helps save space in densely packed electronic assemblies.

4. Response Time: The SMDJ33A features a fast response time, typically in the nanosecond range, ensuring that it can react quickly to transient events and protect downstream components effectively.

5. Clamping Voltage: The clamping voltage is specified at a certain peak pulse current, which indicates the maximum voltage the device will allow during a transient event before it starts to conduct and divert the excess energy away from sensitive components.

6. Operating Temperature Range: The device is designed to operate within a wide temperature range, typically from -55°C to +150°C, making it suitable for various applications, including automotive, industrial, and consumer electronics.

7. Applications: The SMDJ33A is commonly used in applications such as data line protection, power supply protection, and general-purpose transient voltage suppression in circuits where voltage spikes can cause damage to sensitive components.

8. Compliance and Standards: Littelfuse ensures that the SMDJ33A meets various industry standards for reliability and performance, making it a trusted choice for engineers and designers.

Summary:

The SMDJ33A from Littelfuse Inc. is a robust and reliable transient voltage suppressor that provides essential protection for electronic circuits against voltage transients. Its compact surface-mount design, high power handling capability, and fast response time make it an ideal choice for a wide range of applications in modern electronic devices.
