STTA106 is 1A, 600V, High voltage diode, rectifier. This diode that is designed to handle high voltages and has an extremely fast switching or recovery time. These diodes are commonly used in various applications where rapid switching and high voltage capabilities are essential.
The TURBOSWITCH is a very high performance series of ultra-fast high voltage power diodes.
TURBOSWITCH family drastically cuts losses in both the diode and the associated switching IGBT
and MOSFET in all freewheel mode operations and is particulary suitable and efficient in motor
control freewheel applications and in booster diode applications in power factor control
Available either in SMB or DO-15 axial package, these 600V devices are particularly intended for
use on 240V domestic mains […]
1. SPECIFIC TO FREEWHEEL MODE
2. OPERATIONS : FREEWHEEL OR BOOSTER DIODE
3. ULTRA-FAST AND SOFT RECOVERY
4. VERY LOW OVERALL POWER LOSSES IN BOTH THE DIODE AND THE COMPANION
5. HIGH FREQUENCY OPERATIONS
