GENERAL DESCRIPTION QUICK REFERENCE DATA
Glass passivated, sensitive gate SYMBOL PARAMETER MAX. MAX. MAX. UNIT
thyristors in a plastic envelope,
suitable for surface mounting, BT258S (or BT258M)- 500R 600R 800R
intended for use in general purpose V
switching and phase control V
applications. These devices are I
intended to be interfaced directly to I
microcontrollers, logic integrated I
circuits and other low power gate current
trigger circuits.

1 Although not recommended, off-state voltages up to 800V may be applied without damage, but the thyristor may
switch to the on-state. The rate of rise of current should not exceed 15 A/µs.
2 Note: Operation above 110˚C may require the use of a gate to cathode resistor of 1kΩ or less.
