Product data sheet
1. General description
Planar passivated Silicon Controlled Rectifier with sensitive gate in a SOT54 (TO-92) plastic
package. This SCR is designed to be interfaced directly to microcontrollers, logic ICs and other low
power gate trigger circuits.
2. Features and benefits
Planar passivated for voltage ruggedness and reliability
Sensitive gate
Direct triggering from low power gate circuits and logic ICs
3. Applications
Ignition circuits
Lighting ballasts
Protection circuits
Switched Mode Power Supplies
