    • 最小值:130% @ 5mA
    • 最大值:260% @ 5mA 这些参数保证了在不同工作条件下稳定的传输性能。
  • 上升/下降时间:
    • 典型值:上升时间 5µs,下降时间 3µs 快速的切换时间使其适用于需要快速响应的应用。
  • 输入类型: DC
  • 输出类型: 晶体管
  • 电压 - 输出(最大值): 80V
  • 电流 - 输出/通道: 50mA
  • 电压 - 正向 (Vf)(典型值): 1.2V
  • 电流 - DC 正向 (If)(最大值): 60mA
  • Vce 饱和压降(最大): 200mV

工作特性

IS281B 采用表面贴装型(SMD)封装,具体为 SOIC-4(0.173",4.40mm 宽),这使得其在现代电子产品中的集成变得更加便捷和节省空间。

应用场景

IS281B 因其高隔离电压、稳定传输比和快速切换时间,广泛应用于以下领域:

工业控制系统

在工业控制系统中,IS281B 可以用于隔离控制信号和执行器之间的电气连接,防止高压干扰和提高系统的可靠性。

医疗设备

医疗设备对安全性要求非常高,IS281B 的高隔离电压(3750Vrms)使其成为医疗设备中的理想选择,确保患者和操作人员的安全。

汽车电子系统

在汽车电子系统中,IS281B 可以用于各种控制模块,如发动机控制单元、传感器系统等,提供可靠的信号传输和电气隔离。

通信设备

通信设备需要处理各种信号,同时保持高隔离性以防止干扰。IS281B 的快速上升/下降时间和稳定传输比使其适用于高速数据传输应用。

技术优势

高隔离电压

IS281B 提供了 3750Vrms 的高隔离电压,这远超许多其他同类产品,确保在高压环境下保持稳定运行。

快速响应时间

上升时间为 5µs,下降时间为 3µs,这些快速的切换时间使得 IS281B 适用于需要实时响应的应用场景。

宽工作温度范围

支持 -55°C ~ 110°C 的宽工作温度范围,使得 IS281B 可以在各种极端环境中保持正常运行。

低饱和压降

Vce 饱和压降仅为 200mV,这意味着在输出端会有更低的能量损耗,从而提高整体系统效率。

安装和封装

IS281B 采用 SOIC-4(0.173",4.40mm 宽)的表面贴装型封装,这种封装方式不仅节省空间,还便于自动化生产和安装过程。

总结

IS281B 晶体管输出光耦器以其出色的性能参数和广泛的应用场景,成为现代电子工程师和设计师的首选产品。其高隔离电压、快速响应时间、宽工作温度范围以及低饱和压降,使其在工业控制、医疗设备、汽车电子系统以及通信设备等领域都有着重要的作用。如果您正在寻找一款可靠、性能优异的光耦器,IS281B 无疑是一个值得考虑的选择。

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
