Triacs And Thyristors

Available either in through-hole or surface-mount packages, the BTA06 and BTB06 triac series is suitable for general purpose AC switching. They can be used as an ON/OFF function in applications such as static relays, heating regulation, induction motor starting circuits... or for phase control operation in light dimmers, motor speed controllers

Glass passivated triacs in envelope, intended for use in applications requiring high bidirectional transient and blocking voltage capability and high thermal cycling performance.Typical applications include motor control, industrial and domestic lighting, heating and static switching

A glass-passivated thyristor enclosed in a plastic envelope is the BT151-500R. This silicon controlled rectifier (SCR) is designed for uses where strong surge current capability, good bidirectional blocking voltage capability, and high thermal cycling performance are necessary.

In applications including overvoltage crowbar protection motor control circuits in power tools and kitchen appliances inrush current limiting circuits capacitive discharge ignition and voltage regulation circuits the standard 12 A SCR series is appropriate to accommodate all types of control They offer an optimised performance in a constrained space and are available in through hole or surface mount packages

The BTA BTB16 800 triac series which is available in through hole or surface mount packages is appropriate for general purpose AC switching In applications like static relays heating control induction motor starting circuits etc they can be utilised as an ON OFF function or for phase control operation in light dimmers motor speed controllers etc Due to its superior commutation capabilities the snubberless variants BTA BTB W series are especially suggested for usage with inductive loads The BTA series offers UL compliant voltage insulated tab rated at 2500V RMS by utilising an internal ceramic pad

The 40TPS12A SCR Thyristor contains an uncommon P N Hook Collector and a bipolar transistor with 1200V and 1 85V Peak On State Voltage Repetitive Peak Reverse It contains three terminals that mirror thermionic valve vacuum tube technology anode cathode and gate They are frequently used for high voltage AC or DC circuit control or switching AC power control including control of lights motors and other appliances overvoltage protection crowbar for power supply and AC power switching
