Sensitive Gate Triacs Silicon Bidirectional Thyristors

ON Semiconductor 

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
