MAC997/D
MAC997 Series
Preferred Device
Sensitive Gate Triacs
Silicon Bidirectional Thyristors
Designed for use in solid state relays, MPU interface, TTL logic and
any other light industrial or consumer application. Supplied in an
inexpensive TO−92 package which is readily adaptable for use in
automatic insertion equipment.
• One−Piece, Injection−Molded Package
• Blocking Voltage to 600 Volts
• Sensitive Gate Triggering in Four Trigger Modes (Quadrants) for all
possible Combinations of Trigger Sources, and especially for Circuits
that Source Gate Drives
• All Diffused and Glassivated Junctions for Maximum Uniformity of
Parameters and Reliability
• Improved Noise Immunity (dv/dt Minimum of 20 V/μsec at 110°C)
• Commutating di/dt of 1.6 Amps/msec at 110°C
• High Surge Current of 8 Amps
• Device Marking: Device Type, e.g., for MAC997A6: MAC7A6, Date
