12 Amp Alternistor (High Communitation) Triacs

RoHS

Qxx12xHx Series

Description

This 12 Amp bidirectional solid state switch series is

designed for AC switching and phase control applications

such as motor speed and temperature modulation controls,

lighting controls, and static switching relays.

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.

Agency Approval

Applications

Excellent for AC switching and phase control applications

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.

AlternistorTriacs (no snubber required) are used in

applications with extremely inductive loads requiring

highest commutation performance.

Internally constructed isolated packages are offered for

ease of heat sinking with highest isolation voltage.
