DESCRIPTION

Description

OVERVIEW

Product Overview

The SMCJ28A is a unidirectional transient voltage suppression (TVS) diode from CYStek in an SMC (DO-214AB) surface-mount package. When circuit voltage exceeds its breakdown voltage, a TVS diode conducts rapidly to divert transient energy and protect downstream sensitive devices from surges. It is commonly used for overvoltage protection on power inputs, communication interfaces and signal lines. The SMCJ series name reflects its power class and package size; specific breakdown voltage, clamping voltage and peak power parameters should be confirmed from the official datasheet.

APPLICATIONS

Applications

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

Features and Benefits

  • Unidirectional structure suits DC or unidirectional signal circuits.
  • SMC package is compatible with surface-mount processes.
  • Fast response for transient overvoltage diversion.
ADDITIONAL DETAILS

Additional Details

When purchasing, verify the model suffix and package specification, and request the official datasheet from the supplier to confirm breakdown and clamping parameters.

Verify product details against the manufacturer datasheet before purchase.
