Description and Applications

The B340AF is a 3A 40V and B345AF is a 3A 45V single rectifier

packaged in the low profile SMAF package. Providing low VF and

excellent reverse leakage stability at high temperatures, this device is

ideal for use in general rectification applications such as:

 Boost Diodes

 Blocking Diodes

 Recirculating Diodes

Features and Benefits

 Reduced Low Forward Voltage Drop (VF); Better Efficiency and

Cooler Operation

 Reduced High-temperature Reverse Leakage; Increased

Reliability against Thermal Runaway Failure in High

Temperature Operation.

 Lead-Free Finish; RoHS Compliant (Notes 1 & 2)

 Halogen and Antimony Free. “Green” Device (Note 3)

Mechanical Data

 Case: SMAF

 Case Material: Molded Plastic, “Green” Molding Compound. UL

Flammability Classification Rating 94V-0

 Moisture Sensitivity: Level 1 per J-STD-020

 Terminals: Finish - Matte Tin Annealed over Copper Leadframe.

Solderable per MIL-STD-202, Method 208

 Polarity: Cathode Band

 Weight: 0.036 grams (Approximate)
