IS281-4GB 产品概述

IS281-4GB 是一款高性能、四通道的光电耦合器,采用先进的光电隔离技术,旨在满足现代电气及电子设备对信号传输和隔离的高要求。该产品由英国安数光(ISOCOM)生产,具有卓越的性能和广泛的应用场景,成为工业控制、通信、数据采集及其他领域的理想选择。

产品特点

  1. 高通道数设计:IS281-4GB 具备四个独立通道,可以同时处理多路信号,从而减少了元件数量,提高了电路的紧凑性和可靠性。这种多通道设计特别适合需要多路信号隔离的应用,如多路复用器(MUX)和复杂的控制系统。

  2. 强大的电压隔离能力:该光耦的电压隔离能力高达 3750Vrms,极大地降低了系统间的干扰和潜在的电气故障风险。这使得 IS281-4GB 在高压工作环境中仍能保证安全稳定的性能,特别适用于工业设备和电源管理系统。

  3. 高达 600% 的电流传输比:IS281-4GB 在 5mA 的输入电流条件下,提供高达 600% 的电流传输比,确保能够有效地驱动下游电路。其最小电流传输比为 100%,这使得设备能够在低电流条件下依然保持良好的传输性能,提升了系统的兼容性和灵活性。

  4. 快速的响应时间:该产品的上升和下降时间典型值分别为 3µs 和 4µs,保证了在高速信号传输中的出色表现。这对于需要快速脉冲响应和高频信号的应用尤为重要,如数字信号处理和高速通信。

  5. 宽广的工作温度范围:IS281-4GB 支持 -55°C 至 110°C 的工作温度范围,适应性强,能够在极端环境下稳定工作,适合航空航天、汽车电子等高要求应用领域。

  6. 节能与高效:该光电耦合器的正向电压(Vf)典型值为 1.2V,最大正向电流(If)为 50mA,这样的设计不仅减少了能耗,同时也确保了信号的有效传输。此外,其最大饱和压降(Vce)仅为 400mV,进一步提升了设备的能效表现。

  7. 表面贴装型封装:IS281-4GB 采用 16-SOIC 封装(宽度为 4.40mm),适合自动化生产线的表面贴装,便于实现密集布板设计,降低了空间占用,提高了组件的安装效率。

应用场景

由于 IS281-4GB 的多样化特性和卓越性能,它广泛应用于如下场景:

  • 工业控制系统:在自动化机械、传感器和执行器之间提供信号隔离,保障系统安全与稳定。
  • 电源管理:参与电源方案中的输出隔离,确保负载设备不受高压影响。
  • 通信设备:在通信协议中提供信号隔离,确保数据传输的完整性和可靠性。
  • 数据采集:在多通道数据采集系统中,为不同信号源提供独立隔离, 提高抗干扰能力。

总结

IS281-4GB 是一款具有优越性能的四通道光电耦合器,凭借其高电压隔离能力、卓越的电流传输比以及宽广的工作温度范围,已成为现代电子设计中不可或缺的一部分。它不仅简化了复杂电路设计,还提升了系统的可靠性和安全性,适用于各种严苛的应用场景,为用户提供了高效、持久的解决方案。

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
