KBP2005G datasheet by Diodes Incorporated

KBP2005G Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  A thermal pad on the bottom of the package should be connected to a large copper area on the PCB to dissipate heat. Multiple vias can be used to connect the thermal pad to an inner layer or the backside of the PCB for better heat dissipation.
• How do I ensure the bridge rectifier is properly biased?
  The KBP2005G requires a minimum of 1mA of current to ensure proper biasing. A resistor can be added between the AC input and the rectifier input to ensure the minimum current is met.
• What is the maximum allowable voltage imbalance between the AC input lines?
  The maximum allowable voltage imbalance is ±10% of the rated voltage. Exceeding this imbalance may cause the bridge rectifier to malfunction or fail.
• Can I use the KBP2005G in a switching power supply application?
  Yes, the KBP2005G can be used in switching power supply applications, but it's essential to ensure the rectifier is properly snubbed to prevent voltage spikes and ringing.
• How do I protect the KBP2005G from surge currents?
  A surge protection device, such as a transient voltage suppressor (TVS) or a metal oxide varistor (MOV), can be used to protect the KBP2005G from surge currents. The device should be selected based on the expected surge current and voltage.
