SMCJ85CA - LITTELFUSE

SMCJ85CA Frequently Asked Questions (FAQs)

• What is the recommended footprint and land pattern for the SMCJ85CA?
  The recommended footprint and land pattern for the SMCJ85CA can be found in the Littelfuse application note AN9313, which provides guidelines for surface mount assembly of TVS diodes.
• How do I ensure the SMCJ85CA is properly soldered and avoids soldering defects?
  To ensure proper soldering and avoid defects, follow the recommended soldering profile and guidelines outlined in the Littelfuse application note AN9313, and use a solder with a melting point below 260°C.
• What is the maximum operating temperature range for the SMCJ85CA?
  The maximum operating temperature range for the SMCJ85CA is -65°C to 150°C, as specified in the datasheet. However, it's recommended to derate the device's power handling capability at higher temperatures.
• Can the SMCJ85CA be used in high-frequency applications?
  While the SMCJ85CA is primarily designed for transient voltage suppression, it can be used in high-frequency applications up to 1 GHz. However, the device's performance may degrade at higher frequencies due to parasitic inductance and capacitance.
• How do I select the correct SMCJ85CA variant for my specific application?
  Select the correct SMCJ85CA variant by considering factors such as the required standoff voltage, peak pulse current, and package type. Consult the datasheet and Littelfuse's selection guide to determine the most suitable device for your application.
