IS281B 是由英国安数光(ISOCOM)公司生产的一款高性能晶体管输出光耦器,专为需要高隔离电压和稳定传输性能的应用场景设计。以下是对该产品的详细介绍。
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。
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:
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。
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。
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。
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。
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。
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。
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。
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。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
