• Epoxy Meets UL94, VO at 1/8″

• Guaranteed Reverse Avalanche

• Short Heat Sink Tab Manufactured — Not Sheared!

• Similar in Size to the Industry Standard TO-220 Package

Mechanical Characteristics

• Case: Epoxy, Molded

• Weight: 1.7 grams (approximately)

• Finish: All External Surfaces Corrosion Resistant and Terminal Leads are

Readily Solderable

• Lead and Mounting Surface Temperature for Soldering Purposes: 260°C

Max. for 10 Seconds

• Shipped 50 units per plastic tube

• Available in 24 mm Tape and Reel, 800 units per 13″ reel by adding a “T4”

suffix to the part number

• Marking: B1545T
