(> 10 V/ns)
•Guaranteed Reverse Avalanche
•150°C Operating Junction Temperature
Mechanical Characteristics
•Case: Epoxy, Molded
•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
