MCR72-3 Datasheet, PDF (1/4 Pages) ON Semiconductor – SENSITIVE GATE SILICON CONTROLLED RECTIFIERS
MCR72-3, MCR72-6,
MCR72-8
Preferred Device
Sensitive Gate
Silicon Controlled Rectifiers
Reverse Blocking 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 µA Maximum for Direct Driving from
Integrated Circuits
• Device Marking: Logo, Device Type, e.g., MCR72–3, Date Code

(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.
