MCR310/D
MCR310 Series
Preferred Device
Silicon Controlled Rectifiers
Reverse Blocking Triode Thyristors
Designed for industrial and consumer applications such as
temperature, light and speed control; process and remote controls;
warning systems; capacitive discharge circuits and MPU interface.
•Center Gate Geometry for Uniform Current Density
•All Diffused and Glass-Passivated Junctions for Parameter Uniformity
and Stability
•Small, Rugged, Thermowatt Construction for Low Thermal
Resistance, High Heat Dissipation and Durability
•Low Trigger Currents, 200 mA Maximum for Direct Driving from
Integrated Circuits
•Pb−Free Packages are Available

Stresses exceeding Maximum Ratings may damage the device. Maximum
Ratings are stress ratings only. Functional operation above the Recommended
Operating Conditions is not implied. Extended exposure to stresses above the
Recommended Operating Conditions may affect device reliability.
(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.
