Fast Switching Emitter Controlled Diodes, Infineon The Infineon switching emitter controlled diodes are the Rapid 1 and the Rapid 2 families also the 600 V/1200 V Ultra-soft diodes. The diodes work in various applications from Telecom, UPS, welding, AC-DC and the Ultra-soft version works on motor drive applications up to 30 kHz. Rapid 1 diode switches between 18kHz and 40kHz
1.35V temperature-stable forward voltage
Ideal for Power Factor Correction (PFC) topologies

The Rapid 2 diode switches between 40 kHz and 100 kHz
Low reverse recovery charge: forward voltage ratio for BiC performance
Low reverse recovery time
Low turn-on losses on the boost switch

Ultra-fast Diode 600 V/1200 V Emitter Controlled technology
Qualified according to JEDEC Standard
Good EMI behaviour
Low conduction losses
Easy paralleling
