DSEI120-06A
High-current fast recovery diode with 600V rating and 120A capability for high-power SMPS and inverters.
Product Overview
Description
The DSEI120-06A delivers 600V 120A capability with 40ns reverse recovery time for high-power applications. The ultra-low forward voltage drop of 1.25V at rated current maximizes efficiency in high-current rectification.
The TO-247 package with advanced thermal design achieves 0.45°C/W junction-to-case thermal resistance, enabling high current handling with manageable junction temperatures.
Designed for high-power SMPS output rectification, welding equipment, and large motor drive freewheeling applications.

FAE Expert Insights
"The DSEI120-06A is the go-to diode for high-current 600V applications. The 120A rating with 1.25V Vf provides excellent efficiency. I've used these in 10kW+ SMPS, large welding power supplies, and high-power motor drives. The 40ns trr is still quite fast for this current level. Thermal design is critical - at 80A continuous, conduction loss is 100W, requiring substantial heatsinking. The soft recovery helps keep EMI manageable despite the high current. For very high current applications, these can be paralleled with careful layout. Overall, an excellent high-current fast recovery diode with proven reliability."
