MCR106/D
Preferred Device
Reverse Blocking Thyristors
PNPN devices designed for high volume consumer applications
such as temperature, light and speed control; process and remote control,
and warning systems where reliability of operation is important.
• Glass-Passivated Surface for Reliability and Uniformity
• Power Rated at Economical Prices
• Practical Level Triggering and Holding Characteristics
• Flat, Rugged, Thermopad Construction for Low Thermal
Resistance, High Heat Dissipation and Durability
• Device Marking: Device Type, e.g., MCR106–6, Date Code

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.
(2) Torque rating applies with use of compression washer (B52200-F006 or
equivalent). Mounting torque in excess of 6 in. lb. does not appreciably lower
case-to-sink thermal resistance. Anode lead and heatsink contact pad are
common. (See AN209B). For soldering purposes (either terminal connection
or device mounting), soldering temperatures shall not exceed +200°C. For
optimum results, an activated flux (oxide removing) is recommended.
