Thyristors Datasheet
MAC212A8, MAC212A10
Triacs – 400V - 800V
Pb
Description
Designed primarily for full-wave AC control applications, such as
light dimmers, motor controls, heating controls and power
supplies; or wherever full−wave silicon gate controlled solid−state
devices are needed. Triac type thyristors switch from a blocking to
a conducting state for either polarity of applied main terminal
voltage with positive or negative gate triggering.
Features & Benefits
■ Blocking Voltage to 800 Volts
■ All Diffused and Glass
Passivated Junctions for
Greater Parameter Uniformity
and Stability
■ Gate Triggering Guaranteed in
Four Modes (Quadrants)
■ Pb−Free Packages are
Available
■ Small, Rugged, Thermowatt
Construction for Low Thermal
Resistance, High Heat
Dissipation and Durability

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are
not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected.
1. VDRM and VRRM for all types can be applied on a continuous basis. Ratings apply for zero or negative gate voltage; however, positive gate voltage shall not be applied concurrent with negative
potential on the anode. Blocking voltages shall not be tested with a constant current source such that the voltage ratings of the devices are exceeded.
