QJxx10xHx and QJxx10xx Series
10 A High Temperature Alternistor and Standard (High Communication) TRIACs
RoHS
Description
This 10 A high temperature Alternistor and Standard TRIAC series,
offered in TO-220AB, TO-220 isolated, and TO-263 packages, has
150°C maximum junction temperature and 120 A ITSM (60 Hz).
This series enables easier thermal management and higher surge
handling capability in AC power control applications such as heater
control, motor speed control, lighting controls, and static switching
relays. Alternistor TRIAC operates in Quadrants I, II, and III, and
offers high performance in applications requiring high commutation
capability.
Features
■ Recognized to UL 1557
as an Electrically Isolated
Semiconductor Device
■ Solid-state switching
eliminates arcing or contact
bounce that creates voltage
transients
■ Glass-passivated junctions
Pinout Diagram
■ Restricted (or limited) RFI
generation, depending on
activation point sine wave
■ Surge capability up to 120 A
and 60 Hz
TO-220AB (L-Package)
TO-220AB (R-Package)
■ L package UL recognized
under E71639 for Electrical
isolated at 2500 VRMS
■ Requires only a small gate
activation pulse in each
half-cycle
MT2
■ No contacts to wear out from
reaction of switching events
■ RoHS compliant
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.

■ 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.
■ Standard type devices normally operate in Quadrants I & III
triggered from AC line.
