CA-IS3417WT 产品概述

一、产品简介

CA-IS3417WT 是 Chipanalog(川土微)推出的一款增强型绝缘高压隔离开关。器件原边采用模拟二极管(e-diode)输入结构,兼容传统光耦输入特性,同时提供更好的一致性、长期稳定性与可靠性。副边集成耐压高达1700V 的背靠背 SiC MOSFET,实现高压侧安全隔离与开关功能。与传统光MOS继电器相比,CA-IS3417WT 无光衰老化问题、开关寿命更长;相较于机械继电器,具有更多次开关能力和更低电磁干扰(低 EMI)。

二、主要性能与规格(关键参数)

  • 隔离耐压:5000 Vrms
  • 通道数:1 路
  • 负载类型:MOSFET(SiC 背靠背)
  • 工作温度(Ta):-40℃ ~ +125℃
  • 上升时间 tr:16,000 ns(16 μs)
  • 下降时间 tf:9,200 ns(9.2 μs)
  • 传播延迟 tpLH:150,000 ns(150 μs)
  • 传播延迟 tpHL:100,000 ns(100 μs)
  • 共模瞬态抗扰度 CMTI:150 kV/μs
  • 封装:SOIC-12-WB

三、器件构造与封装

该器件原边为模拟二极管输入,能与现有光耦驱动逻辑直接兼容,减小设计迁移成本;副边集成背靠背 SiC MOSFET,额定耐压高达1700V,以SOIC-12-WB 封装提供标准化 PCB 布局与散热考虑。SiC 元件带来更好的高温特性与长期可靠性,适合苛刻环境使用。

四、主要优势

  • 抗光衰与长寿命:无传统光耦的光衰老化问题,开关次数远超机械继电器。
  • 低 EMI:电路与封装优化,降低开关过程中的电磁干扰。
  • 高 CMTI 能力:150 kV/μs,适用于强共模干扰环境的隔离应用。
  • 宽温度适应性:-40℃ 至 +125℃ 的工作范围,适合工业级和汽车级温度要求。
  • 高压耐受:副边 SiC MOSFET 背靠背设计支持高达 1700V 的耐压等级。

五、典型应用

  • 工业电源与逆变器的高压隔离开关与测试隔离
  • 电池管理系统(BMS)与能量切换电路
  • 光伏逆变器与风力发电系统的安全隔离
  • 高压测试设备与测量仪器
  • 医疗设备与通信基站中需要高可靠性的隔离方案

六、使用与选型建议

  • 由于器件传播延迟与上/下降时间偏长(数十至数百微秒量级),适合低频或静态开关、保护隔离场景,不建议用于高频功率开关快速脉冲控制。
  • 关注热管理与功耗,SiC MOSFET 在高温下表现优异,但在高电流场景下仍需合理散热设计与额定电流评估。
  • 输入驱动可按光耦级兼容方式设计,但应参考厂方输入特性以保证可靠触发电平与抗噪能力。
  • 若系统对开关速度敏感,应在选型前确认 tr/tf 与 tpLH/tpHL 是否满足控制时序要求。

总结:CA-IS3417WT 将光耦兼容输入与高压 SiC MOSFET 副边集成在一起,提供了一种可靠、耐高温、低 EMI 的高压隔离开关方案,适用于需要长期稳定性和高共模抗扰能力的工业与电力电子系统。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
