Key Takeaways The boost diode in a power factor correction stage lives a hard life: it blocks 400–800 V, switches at the converter frequency, and carries the full output current. Before you finalize the BOM, compare the related options: When a SiC Schottky Diode Improves CCM PFC Efficiency and EMI and Schottky Barrier Rectifier Diode. … Read more
A fast recovery diode is a rectifier designed to change from forward conduction to reverse blocking with shorter recovery than a standard-recovery device under comparable conditions. It can reduce recovery-related stress in suitable switching circuits, but the best choice depends on recovery charge, forward loss, temperature and the way the circuit forces the diode to … Read more
SMB fast recovery diodes trade footprint for thermal headroom. What a 2 A part really carries, and how package, recovery and surge decide the design.
The same 1 A ultrafast die is 45 °C/W junction-to-lead in DO-41, 30 in SMA and 25 in SMB. How SMA package choice, recovery and heat decide the part.
In one 600 V family the 30 A TO-247 diode is rated 0.70 °C/W junction-to-case and the 60 A part 0.38 °C/W. How the thermal path sets usable current.
