Preferred Device
Silicon Controlled Rectifiers
Reverse Blocking Thyristors
Designed primarily for half-wave ac control applications, such as
motor controls, heating controls and power supplies; or wherever
half-wave silicon gate-controlled, solid-state devices are needed.
• Glass-Passivated Junctions
• Blocking Voltage to 400 Volts
• TO-220 Construction — Low Thermal Resistance, High Heat
Dissipation and Durability
• Device Marking: Logo, Device Type, e.g., MCR218–2, 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.
