Introduction

AI Translation

The 2N4991 is a silicon planar monolithic integrated circuit with the electrical characteristics of a bidirectional thyristor. The device is designed for switching operation at 8 volts, with a temperature coefficient of 0.02%/°C and well-matched characteristics in both directions. A gate lead is provided to eliminate rate effects and enable triggering at lower voltages. The 2N4991 is designed for applications requiring stable switching voltage over a wide temperature range with good bidirectional matching characteristics. It is ideally suited for half-wave and full-wave triggering in low-voltage SCR and TRIAC phase control circuits.
