Product Description

Product Overview

The B0520LW/B0530W/B0540W series are Schottky diodes housed in a molded plastic body with plated leads solderable per MIL-STD-750, Method 2026. These diodes feature low forward voltage drop and guard ring construction for transient protection, offering high conductance. They are also available in a lead-free version. Typical applications include general rectification where low forward voltage drop is critical.

Product Attributes

  • Case: Molded plastic body
  • Terminals: Plated leads
  • Polarity: Symbols marked on case
  • Available in lead-free version
