8V 1AMP Silicon Unilateral Switch

Item no. 2N4987
$9.75


Product discontinued

Overview

The 2N4987 is a planar monolithic silicon integrated circuit having thysistor electrical characteristics closely approximating those of an "ideal" four layer diode.  This device is designed to switch at 8V with a 0.02%/°C temperature coefficent. A gate lead is provided to eliminate rate effect, obtain triggering information at lower voltages and obtain transient free wave forms.

Silicon Unilateral Switches are specifically designed snf characterized for use in monostable and bistable applications where low cost if of prime importance. Supplied in a JDEC TO-88 package.

Applications:

  • SCR Triggers
  • Frequency Drivers
  • Ring Counters
  • Cross Point Switching
  • Over-Voltage Sensors
