D_SMB (DO-214AA)

Package: D_SMB Library: Diode_SMD Category: Diode Pads: 2 Pitch: N/A Body Size: 5.3 x 3.6mm Mounting: Surface Mount

Description

The SMB (DO-214AA) is a medium-power surface-mount diode package, one size up from the SMA. At 5.3 x 3.6mm, it handles higher power and surge currents, making it the standard package for TVS (transient voltage suppressor) diodes protecting power rails and data lines from ESD and lightning surges. Also used for higher-current rectifiers (up to 3A), Schottky barrier diodes in power supplies, and Zener voltage regulators. Common in automotive, industrial, and telecom designs requiring robust overvoltage protection.

Usage Notes

  • Designed for reflow soldering (paste stencil recommended)
  • Pad size optimized for standard components
  • Follow IPC-7351 land pattern guidelines
