• Soft recovery characteristics eliminate the need for snubber circuits in most applications.
• Extensive characterization of recovery parameters across varying currents, temperatures, and di/dt values simplifies loss calculations.

Single Diodes Applications

• High-frequency power converters
• Motor drives
• Applications where switching losses constitute a significant portion of total system losses

Single Diodes Procurement Notes

Verify the specific manufacturer origin, as datasheet references indicate historical production by International Rectifier before acquisition by Vishay. Confirm RoHS compliance status and check for active manufacturing or obsolescence notices directly with the supplier. Ensure mounting torque specifications are strictly followed during installation to maintain thermal performance and mechanical integrity.

Single Diodes Selection Notes

Select this component when designing high-current, high-frequency rectification stages requiring soft recovery behavior. Evaluate thermal management requirements based on the 0.24°C/W junction-to-case resistance. Consider the 600V blocking capability and 193A continuous current rating against the specific operating temperature and duty cycle constraints of the target application circuit.
