ACST310-8FP中文资料Overvoltage protected AC switch数据手册ST规格书

描述 Description

The ACST310-8FP belongs to the ACS™ / ACST power switch family built with A.S.D.®(application specific discrete) technology. This high performance device is suited to home appliances or industrial systems and drives loads up to 3 A.
This ACST310-8FP switch embeds a Triac structure and a high voltage clamping device able to absorb the inductive turn-off energy and withstand line transients such as those described in the IEC 61000-4-5 standard.The component needs a low gate current to be activated (IGT max. 10 mA) and still shows a high electrical noise immunity complying with IEC standards such as IEC 61000-4-4 (fast transient burst test). It provides UL certified insulation rated at 2000 VRMS(file ref: E81734).

特性 Features

• AC switch with self over voltage protection
• Microcontroller direct driven (low gate current max. 10 mA)
• Three quadrants (Q1, Q2 and Q3)
• UL94-V0 qualified resin (flammability)
• Complies with UL standards UL1557
• Insulated voltage: 2000 VRMS
• ECOPACK®2 compliant component
• Benefits
• Enables equipment to meet IEC61000-4-5
• High immunity against fast transients described in IEC61000-4-4 standard
• Needs no external overvoltage protection
• High off-state reliability power device
• Interfaces directly with the microcontroller
• Reduces component count

简介

ACST310-8FP属于分立半导体产品的晶闸管-TRIAC。由制造生产的ACST310-8FP晶闸管 - TRIAC晶闸管可沿一个方向或在半个 AC 周期内传导 AC（交流电）。当 TRIAC（三极管 AC）的门极被触发时，即会沿任一方向传导电流。其他名称包括双向三极晶闸管或双侧三极晶闸管。TRIAC 分为无缓冲器、Alternistor、内部触发、逻辑门和标准型，安装方式包括底座、表面或通孔安装。这些器件可根据断态电压、通态电流、保持电流和门极触发电压进行选择。
