MCR218-2, MCR218-4,
MCR218-6

Preferred Device

Silicon Contr olled 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 T ype, e.g., MCR218–2, Date Code
