A 650V Silicon Junction Rectifier Diode (EmCon HE series) in a TO-247 (3-pin) package.

Key Specs

• Manufacturer: Infineon Technologies
• Marking Code: D75ED1
• Type: Silicon Junction diode, single configuration
• Max Forward Current (I_F): 75A
• Max Reverse Voltage (V_RRM): 650V 
• Peak Surge Current (I_FSM): 580A
