SMBJ110A-Q - Bourns

SMBJ110A-Q Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the SMBJ110A-Q?
  The recommended PCB layout for optimal performance of the SMBJ110A-Q includes keeping the leads as short as possible, using a ground plane under the device, and minimizing the distance between the device and the protection circuitry. Additionally, it is recommended to use a via or a thermal pad to connect the device to the ground plane.
• How does the SMBJ110A-Q handle surge currents?
  The SMBJ110A-Q is designed to handle high surge currents, with a peak pulse current rating of 110A. The device uses a proprietary silicon avalanche technology to absorb and divert surge currents away from the protected circuitry.
• What is the response time of the SMBJ110A-Q to an ESD event?
  The response time of the SMBJ110A-Q to an ESD event is typically in the range of 1-2 nanoseconds. This fast response time helps to protect sensitive circuitry from damage caused by ESD events.
• Can the SMBJ110A-Q be used in high-temperature applications?
  Yes, the SMBJ110A-Q is rated for operation up to 150°C, making it suitable for use in high-temperature applications. However, it is recommended to derate the device's performance at high temperatures to ensure reliable operation.
• Is the SMBJ110A-Q compatible with automotive applications?
  Yes, the SMBJ110A-Q is compatible with automotive applications and meets the requirements of ISO 7637-2, which specifies the test methods and requirements for electromagnetic compatibility (EMC) in vehicles.
