UMD05-323 - Small Surface Mount Device TVS

General Description

TVS diodes are designed to replace multilayer varistors (MLVs) in portable applications such as cell phones, notebook computers, and PDA’s.

They offer superior electrical characteristics such as lower clamping voltage and no device degradation when compared to MLVs.

Key Features

  • Solid-state silicon-avalanche technology.
  • SOD-323 package.
  • Uni-Directional protection.
  • Protects one I/O or Power line.
  • 500 Watts peak pulse power (tp = 8/20µs).
  • Working voltage: 5V.
  • Low clamping factor Vcl/Vbr.
  • Low leakage current.
  • Complies with the following standards: - IEC 61000-4-2 (ESD) Air-15kv, Contact-8kv - IEC 61000-4-4 (EFT) 40A (5/50ns) - IEC 61000-4-5 (Surge) 24A (8/20µs) Mechanical Characteristics.
  • Molded JEDEC SOD-323 package.
