Connected for Parallel Operation at Full Rating
• 45 Volt Blocking Voltage
• Low Forward Voltage Drop
• Guardring for Stress Protection and High dv/dt Capability
(> 10 V/ns)
• Guaranteed Reverse Avalanche
• 150°C Operating Junction Temperature
Mechanical Characteristics
• Case: Epoxy, Molded
2,4
• Weight: 4.3 grams (approximately)
• Finish: All External Surfaces Corrosion Resistant and Terminal
Leads are Readily Solderable
• Lead Temperature for Soldering Purposes: 260°C Max. for 10
Seconds
• Shipped 30 Units Per Plastic Tube
• Marking: B4045
