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.
The NXP BT258S-800LT is a passivated sensitive gate Silicon Controlled Rectifier (SCR) designed for high bidirectional blocking voltage and high thermal cycling performance. It is housed in a SOT428 (DPAK) surface mountable plastic package and is intended for direct interfacing with microcontrollers, logic integrated circuits, and other low power gate trigger circuits.
Key features include high junction operating temperature capability (up to 150 °C), very sensitive gate for logic level controls, and planar passivation for voltage ruggedness. Typical applications include general purpose switching, phase control, ignition circuits for 2- and 3-wheelers, motor control for small kitchen appliances, and protection circuits for Switched-Mode Power Supplies (SMPS) and lighting ballasts.
