1KSMB20A Frequently Asked Questions (FAQs)

  • The recommended footprint and land pattern for the 1KSMB20A can be found in the Littelfuse application note AN9313, which provides guidelines for surface mount assembly of TVS diodes.
  • 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.
  • The 1KSMB20A has an operating temperature range of -65°C to 150°C, but it's recommended to derate the device's power rating above 125°C to ensure reliable operation.
  • While the 1KSMB20A is primarily designed for transient voltage suppression, it can be used in high-frequency applications up to 1 GHz, but the user should consider the device's parasitic capacitance and inductance when designing the circuit.
  • To select the correct TVS diode, consider the following factors: working voltage, peak pulse current, clamping voltage, and response time. Consult the Littelfuse TVS diode selection guide or contact a Littelfuse application engineer for assistance.
