15 Amp Standard & 16 Amp Alternistor (High Commutation) Triacs
Qxx15xx & Qxx16xHx Series
Description
The 15 Amp and 16 Amp bi-directional solid state switch
series are designed for AC switching and phase control
applications such as motor speed, temperature modulation
controls, lighting controls, and static switching relays.
Standard type components normally operate in Quadrants I
& III triggered from AC line.
Alternistor type components only operate in quadrants I, II,
& III and are used in circuits requiring high dv/dt capability.
Main Features
Symbol Value Unit
IT(RMS) 15 & 16 A
VDRM /VRRM 400 to 1000 V
IGT (Q1) 10 to 80 mA
Features & Benefits
• RoHS Compliant
• Glass – passivated
junctions
• Voltage capability up to
1000 V
• Surge capability up to
200 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 in sine
wave
• Requires only a small
gate activation pulse in
each half-cycle
Schematic Symbol
Applications
Excellent for AC switching and phase control applications
such as heating, lighting, and motor speed controls.
Typical applications are AC solid-state switches, light
dimmers, power tools, lawn care equipment, home/brown
goods and white goods appliances.
Alternistor Triacs (no snubber required) are used in
applications with high inductive loads requiring highest
commutation performance.
Internally constructed isolated packages are offered for
ease of heat sinking with highest isolation voltage.

Design Considerations
Careful selection of the correct component for the
application’s operating parameters and environment will
go a long way toward extending the operating life of the
Thyristor. Good design practice should limit the maximum
continuous current through the main terminals to 75% of
the component rating. Other ways to ensure long life for
a power discrete semiconductor are proper heat sinking
and selection of voltage ratings for worst case conditions.
Overheating, overvoltage (including dv/dt), and surge
currents are the main killers of semiconductors. Correct
mounting, soldering, and forming of the leads also help
protect against component damage.
