40EPS12 High Voltage Input Rectifier Diode 40A 1200V TO-247AC-2L
High voltage rectifier optimized for a very low forward voltage drop with moderate leakage. It features a glass passivated pellet chip junction and single-diode circuit configuration. The device is intended for use in main input rectification applications (single or three-phase bridge).
Features
- Very low forward voltage drop for increased efficiency
- 150 °C maximum operating junction temperature
- Glass passivated pellet chip junction for robust reliability
- Environmentally compliant
