DESCRIPTION

Description

OVERVIEW

Product Overview

The SMBJ15A is a unidirectional transient voltage suppression (TVS) diode from CYStek in an SMB (DO-214AA) surface-mount package. When transient overvoltage exceeds its breakdown voltage, the device conducts rapidly to divert surge energy, protecting downstream circuits from damage. The SMB package balances power handling and board footprint, making it suitable for overvoltage protection on power inputs, interfaces and signal lines. Specific breakdown voltage, clamping voltage and peak pulse power parameters should be confirmed from the official datasheet.

APPLICATIONS

Applications

  • Used for surge and overvoltage protection at power inputs.
  • Protects data interfaces from transient voltage strikes.
  • Can suppress overvoltage on signal lines.
FEATURES AND BENEFITS

Features and Benefits

  • Unidirectional structure suits DC and unidirectional signal lines.
  • SMB package balances power and board footprint.
  • Fast response quickly diverts transient energy.
