BT258S-800R

BT258S-800R Logic level thyristor 5 September 2018 Product data sheet 1. General description Planar passivated 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. 2. Features and benefits Direct interfacing with low power drivers and microcontrollers High bidirectional blocking voltage capability High thermal cycling performance Planar passivated for voltage ruggedness and reliability Sensitive gate suitable for logic level controls Surface mountable package 3. Applications General purpose switching and phase control Protection circuits Ignition circuits, CDI for 2- and 3-wheelers Motor control - e.g. small kitchen appliances 4.
