15 Amp Standard & 16 Amp Alternistor (High Commutation) Triacs
RoHS
Qxx15xx & Qxx16xHx Series
Description
This 15 Amp and 16 Amp bi-directional solid state switch
series is designed for AC switching and phase control
applications such as motor speed, temperature modulation
controls, lighting controls, and static switching relays.
Standard type devices normally operate in Quadrants I & III
triggered from AC line.
Standard alternistor triac components operate with in-phase
signals in Quadrants I or III and ONLY unipolar negative gate
pulses for Quadrant II or III. The alternistor triac will not
operate in Quadrant IV.These are used in circuit applications
requiring a high dv/dt capability.

such as heating, lighting, and motor speed controls.
MT2
MT1
Typical applications are AC solid-state switches, light
dimmers, power tools, lawn care equipment, home/brown
goods and white goods appliances.
G
Alternistor Triacs (no snubber required) are used in
applications with extremely inductive loads requiring
highest commutation performance.
Additional Information
Internally constructed isolated packages are offered for
ease of heat sinking with highest isolation voltage.
