4 Amp Sensitive & Standard Triacs

Lxx04xx & Qxx04xx Series

Lxx04xx & Qxx04xx Series

Description

Main Features

4 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.

Sensitive type devices guarantee gate control in Quadrants

I & IV needed for digital control circuitry.

Standard type devices normally operate in Quadrants I & III

triggered from AC line.

Applications

Typical applications are AC solid-state switches, power

tools, home/brown goods and white goods appliances.

Sensitive gate Triacs can be directly driven by

microprocessor or popular opto-couplers/isolators.

Internally constructed isolated packages are offered for

ease of heat sinking with highest isolation voltage.

Features & Benefits

• RoHS Compliant

• Glass – passivated

junctions

• Voltage capability up to

1000 V

• Surge capability up to

55 A

• Electrically isolated

“L-Package” is UL

recognized for 2500Vrms

• Solid-state switching

eliminates arcing or

contact bounce that

create voltage transients

• No contacts to wear out

from reaction of switching

events

• Restricted (or limited) RFI

generation, depending on

activation point of

sine wave

• Requires only a small gate

activation pulse in each

half-cycle
