Study Notes
LASCR Characteristics
- LASCR conducts current in one direction when activated by a sufficient amount of light energy
- The gate terminal of LASCR is most sensitive to light when it is open
Operating Conditions
- An increase in junction temperature results in a reduction in trigger energy required to activate LASCR
- An increase in junction temperature reduces the trigger energy required to activate LASCR
OR Circuit Operation
- Light energy applied to LASCR 1 or LASCR 2 results in the supply voltage appearing across the load
- Light energy applied to LASCR 1 or LASCR 2 turns on the load
LASCR Comparison
- LASCR operates essentially as does the conventional SCR except that it can also be triggered by light
Trigger Mechanism
- The input source turns on the lamp; the resulting incident light triggers the LASCR
