Description

The SIDAC is a silicon bilateral voltage triggered switch. Upon application of a voltage exceeding the SIDAC breakover voltage point, the SIDAC switches on through a negative resistance region to a low on-state voltage. Conduction continues until the current is interrupted or drops below the minimum holding current of the device. SIDACs feature glass-passivated junctions to ensure a rugged and dependable device capable of withstanding harsh environments.

Features

• AC Circuit Oriented

• Triggering Voltage of 79V to 330V

• RoHS Compliant

Applications

Suitable for high voltage power supplies, natural gas igniters, high-pressure Sodium lamps, and Xenon flash ignition.

K0900S属于分立半导体产品 > 晶闸管 - DIAC，SIDAC。力特公司制造生产的K0900S晶闸管 - DIAC，SIDACDIAC 和 SIDAC 系列产品是双端子器件，常在交流相位控制应用中用作触发机制，其作用是阻断电流，直至器件两端施加的电压达到某个临界值才会导通，并在导通瞬间提供大电流。两者的区别在于特性曲线的形状；导通模式下，DIAC（双向触发二极管）的正向电压通常较高，因此当应用要求电流较大时，SIDAC（高压双向触发二极管）通常比它更加适用。
