The recommended footprint and land pattern for SMBJ170A-E3/5B can be found in the Vishay Intertechnologies' application note AN10365, which provides guidelines for surface-mount assembly of SMB packages.
To ensure reliability in high-temperature applications, it is essential to follow the recommended derating curves for voltage and current, and to consider the device's thermal resistance and power dissipation. Additionally, ensure that the device is soldered correctly and that the PCB is designed to minimize thermal stress.
Yes, the SMBJ170A-E3/5B can be used in a bidirectional configuration, but it is essential to ensure that the device is connected correctly, with the anode connected to the positive rail and the cathode connected to the negative rail. Additionally, the device's peak pulse current rating should be considered to ensure that it can handle the expected surge currents.
The maximum operating temperature range for the SMBJ170A-E3/5B is -55°C to +150°C, as specified in the datasheet. However, it is essential to consider the device's derating curves and thermal resistance to ensure reliable operation in high-temperature applications.
To select the correct SMBJ170A-E3/5B variant, consider the required standoff voltage, peak pulse current, and power dissipation. The datasheet provides a range of options with different voltage and current ratings, so select the device that best meets your application's requirements.
