MCR12D, MCR12M, MCR12N
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 devices are needed.
• Blocking Voltage to 800 Volts
• On–State Current Rating of 12 Amperes RMS at 80°C
• High Surge Current Capability — 100 Amperes
• Rugged, Economical TO220AB Package
• Glass Passivated Junctions for Reliability and Uniformity
• Minimum and Maximum Values of IGT, VGT an IH Specified for
Ease of Design
• High Immunity to dv/dt — 100 V/µsec Minimum at 125°C
• Device Marking: Logo, Device Type, e.g., MCR12D, Date Code

(1) VDRM and VRRM for all types can be applied on a continuous basis. Ratings
apply for zero or negative gate voltage; 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.
