Qxx40xx Series - 40 Amp Alternistor (High Communication) Triacs

40 Amp Alternistor (High Communication) Triacs
Roll Over to Zoom
40 Amp bi-directional 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.

Alternistor type devices only operate in quadrants I, II, & III and are used in circuits requiring high dv/dt capability.

Features & Benefits:
  • RoHS Compliant
  • Glass - passivated junctions
  • Voltage capability up to 1000V
  • Surge capability up to 400A
  • Electrically isolated K & J -Packages are UL recognized for 2500Vrms


Applications:
  • Excellent for AC switching and phase control applications such as heating, lighting, and motor speed controls.
  • Typical applications are AC solid-state switches, industrial power tools, exercise equipment, white goods and commercial appliances.
  • Alternistor Triacs (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.
