2N6394_06 Datasheet, PDF (1/5 Pages) ON Semiconductor – Silicon Controlled Rectifiers SCRs 12 AMPERES RMS 50 thru 800 VOLTS
2N6394 Series
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.
Features
• Glass Passivated Junctions with Center Gate Geometry for Greater
Parameter Uniformity and Stability
• Small, Rugged, Thermowatt Construction for Low Thermal
Resistance, High Heat Dissipation and Durability
• Blocking Voltage to 800 V
• Pb−Free Packages are Available*

Stresses exceeding Maximum Ratings may damage the device. Maximum
Ratings are stress ratings only. Functional operation above the Recommended
Operating Conditions is not implied. Extended exposure to stresses above the
Recommended Operating Conditions may affect device reliability.
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.
