Understanding Thermal Specification of Bridge Rectifiers APPLICATION NOTE

2022-05-10
●Mastering thermal management of power applications is one of the highly underestimated challenges electronic designers must overcome. This application note explains the mechanisms of heat transfer in semiconductor components along with Diotec’s datasheet para-meters of 1ph and 3ph Bridge Rectifier. It further describes a way to determine whether a bridge is suitable for a given output current and ambient respectively case temperature.The conduction of electric current at a voltage generates heat in a semiconductor material thus increasing the temperature of the pn-junction. A higher temperature is directly tied to an increased probability of failures and a reduced component lifetime. In order to assure safe operation, designers must take measures to reduce the junction temperature during operation.
