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
