P6SMB33A

The P6SMB33A is a specific model of transient voltage suppressor (TVS) diode manufactured by Bourns, Inc. This component is designed to protect sensitive electronic devices from voltage spikes and transients, which can occur due to various factors such as lightning strikes, electrostatic discharge (ESD), or inductive load switching.

Key Features and Specifications:

1. Type: The P6SMB33A is a unidirectional TVS diode, meaning it is designed to clamp voltage in one direction, providing protection for circuits that require a specific polarity.

2. Peak Power Rating: It typically has a peak power rating of around 600 watts, which allows it to absorb significant energy from transient events without failing.

3. Reverse Stand-Off Voltage (V_RWM): The device has a reverse stand-off voltage of 33 volts, which indicates the maximum voltage that can be applied to the diode without causing it to conduct. This makes it suitable for protecting circuits operating at or below this voltage.

4. Clamping Voltage (V_C): When a transient event occurs, the clamping voltage is the maximum voltage that the diode will allow to pass through. For the P6SMB33A, this is typically around 50 volts at a specified peak pulse current, ensuring that the voltage seen by the protected device remains within safe limits.

5. Capacitance: The diode has a low capacitance value, which is crucial for high-speed applications, as it minimizes signal distortion and ensures that the performance of the circuit is not adversely affected.

6. Package Type: The P6SMB33A is housed in a DO-214AA (SMB) package, which is a surface-mount device (SMD) that allows for easy integration into printed circuit boards (PCBs). The package is designed for efficient thermal dissipation and robust mechanical stability.

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

8. Applications: The P6SMB33A is commonly used in applications such as telecommunications, automotive electronics, consumer electronics, and industrial equipment, where protection from voltage transients is critical.

9. Compliance and Standards: Bourns ensures that the P6SMB33A meets various industry standards for reliability and performance, making it a trusted choice for engineers and designers.

Summary:

In summary, the P6SMB33A from Bourns, Inc. is a robust and reliable transient voltage suppressor diode that provides essential protection for electronic circuits against voltage spikes. Its combination of high power handling, low clamping voltage, and compact packaging makes it an ideal choice for a wide range of applications where circuit integrity and reliability are paramount.
