SCR (Silicon Controlled Rectifier)	Four-layer PNPN, 3 terminals (gate, anode, cathode)	High current/voltage control, unidirectional conduction, latching behavior	Motor control, power regulation, industrial drives, dimmer switches	Voltage rating, current capacity, gate trigger requirements, thermal management
Triac	Three-terminal, inverse parallel SCR configuration	Bidirectional conduction, controls both AC half-cycles, smooth motor operation	Motor speed control, AC power regulation, lighting control	Load current rating, triggering sensitivity, commutation capability
Diac	Bi-directional diode structure	Triggers at breakover voltage, used to activate triacs/SCRs	Triggering circuits, AC switching applications	Breakover voltage tolerance, leakage current specifications
SCS (Silicon Controlled Switch)	Four-layer PNPN, dual gate terminals	Can be turned on/off via either gate, flexible control	Precision switching, control circuits	Gate voltage requirements, switching speed, latching characteristics
LASCR (Light-Activated SCR)	Light-sensitive semiconductor layer	Activated by light, electrical gate backup option	High-voltage isolation, optical control systems	Light sensitivity, gate terminal availability, isolation rating

Technical specifications compiled from GlobalSpec selection guide and industry standards ^[9]^[10].

Key Technical Specifications for Buyer Evaluation:

• Voltage Rating: Maximum blocking voltage in off-state, critical for safety margins • Current Capacity: Continuous and surge current ratings, determines load handling • Switching Speed: Turn-on/turn-off times, especially important for fast thyristors (below 10 microseconds) • Thermal Management: Junction temperature ratings, heat dissipation requirements (proper thermal management increases lifespan by 30%) • Package Type: TO-220, TO-3, DPAK, D2PAK, SOT223, etc., affects mounting and heat sinking • RoHS Compliance: Mandatory for EU and many international markets ^[9]^[10]

Thyristors are a class of four-layer (PNPN) semiconductor devices that act as switches, rectifiers, or voltage regulators. When triggered, thyristors turn on and become low-resistance current paths and remain so, even after the trigger is removed, until the current is reduced to a certain level ^[9].

Industry Standards: BS IEC 60747-6 (Semiconductor devices - Thyristors) and EIA-397 (comprehensive thyristor principles, classes, physical structure, test methods and ratings) provide standardized frameworks for product specification and testing ^[9].
