A TRIAC is equivalent to two Silicon Controlled Rectifiers (SCRs) connected in:
AAnti-parallel (inverse-parallel) with a common gate
BSeries back-to-back
CBridge configuration
DParallel with same polarity
Explanation
A TRIAC (Triode for Alternating Current) is a 5-layer bidirectional semiconductor device equivalent to two SCRs connected in anti-parallel (inverse-parallel) with a single common gate terminal to control AC power in both directions.
