BT258S-800LT

Passivated sensitive gate Silicon Controlled Rectifier (SCR) in a SOT428 (DPAK) surface mountable plastic package intended for use in applications requiring high bidirectional blocking voltage capability and high thermal cycling performance. These devices are intended to be interfaced directly to microcontrollers, logic integrated circuits and other low power gate trigger circuits.

Features and Benefits
  • Direct interfacing with low power drivers and microcontrollers
  • High bidirectional blocking voltage capability
  • High junction operating temperature capability
  • High thermal cycling performance
  • Planar passivated for voltage ruggedness and reliability
  • Surface mountable package
  • Very sensitive gate for logic level controls
Applications
  • General purpose switching and phase control
  • Ignition circuits, CDI for 2- and 3-wheelers
  • Motor control - e.g. small kitchen appliances
  • Protection circuits for Switched-Mode Power Supplies (SMPS)
  • Protection circuits in lighting ballasts
