SMBJ8.5CA

The SMBJ8.5CA is a specific type of transient voltage suppressor (TVS) diode manufactured by Jiangsu JieJie Microelectronics. This component is designed to protect sensitive electronic circuits from voltage spikes and transients, which can occur due to various factors such as lightning strikes, electrostatic discharge (ESD), or switching surges.

Key Features and Specifications:

1. Type and Configuration:

   • The SMBJ8.5CA 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:

   • The device 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 reverse stand-off voltage for the SMBJ8.5CA is rated at 8.5 volts. This is the maximum voltage that can be applied to the diode without causing it to conduct.

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 SMBJ8.5CA, this is typically around 12.5 volts at a specified peak pulse current.

5. Peak Pulse Current (I_PP):

   • The diode can handle a peak pulse current of approximately 30 amperes, which is crucial for protecting circuits from high-energy transients.

6. Package Type:

   • The SMBJ8.5CA is housed in a surface-mount package, specifically the SMB (DO-214AA) package, which is compact and suitable for automated assembly processes.

7. 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 environmental conditions.

8. Applications:

   • This TVS diode is commonly used in applications such as telecommunications, automotive electronics, consumer electronics, and industrial equipment, where protection from voltage spikes is critical.

9. Compliance and Standards:

   • The SMBJ8.5CA is often compliant with various industry standards, ensuring reliability and performance in critical applications.

Summary:

The SMBJ8.5CA from Jiangsu JieJie Microelectronics is a robust and reliable transient voltage suppressor diode, ideal for protecting sensitive electronic components from voltage transients. Its specifications, including a reverse stand-off voltage of 8.5 volts and a peak power rating of 600 watts, make it suitable for a wide range of applications in various electronic devices. The compact SMB package allows for easy integration into modern circuit designs, ensuring effective protection without compromising space.
