2N4987 switch equivalent, silicon unilateral switch.
where low cost is of prime importance.
Applications:
D SCR Triggers D Frequency Dividers D Ring Counters D Cross Point .
The 2N4987 is a planar monolithic silicon integrated circuit having thyristor electrical characteristics closely approximating those of an “ideal” four layer diode. The device is designed to switch at 8V with a 0.02%/C temperature coefficient. A ga.
