产品概述:IS281GR
IS281GR 是一种高性能的光电耦合器,采用表面贴装型(SMD)封装,专为需要高隔离电压和高电流传输能力的应用而设计。其独特的结构使其在电气噪声隔离、信号传输和系统保护方面表现出色,非常适合用于各种工业自动化、消费电子和通信设备中。以下是该产品的详细介绍。
基础参数
IS281GR 具有单通道设计,适用于多种低功耗和高可靠性的信号传输需求。其绝缘电压高达 3750Vrms,确保在高电压环境下仍能保持系统的稳定性和安全性。这一特性使得 IS281GR 成为电力系统、数据通信以及其他高电压应用的理想选择。
在输入和输出方面,IS281GR 使用晶体管输出,最大输出电压可达 80V,输出电流可达 50mA,提供了较高的驱动能力,适合在负载较大的应用中使用。具体来看,当输入电流为 5mA 时,电流传输比可在 100% 到 300% 之间变化,这意味着可以根据不同的工作条件灵活调整,实现最佳性能。
响应时间
该光耦的上升时间和下降时间分别为 5µs 和 3µs,这个响应速度对于大多数需要快速开关的电子设备来说,是非常合适的。这样的响应时间确保了有效的信号传递与中断,减少了系统的延迟,为各种数字信号处理应用提供了保证。
电气特性
IS281GR 的正向电压(Vf)通常为 1.2V,而其最大 DC 正向电流(If)为 60mA,这为设备提供了灵活的输入范围和比较宽的工作区间。此外,其 Vce 饱和压降最大为 200mV,确保在导通状态下,能有效保持较低的功耗和发热,提升了整体的能效,是低功耗设计的重要考虑。
环境适应性
IS281GR 的工作温度范围从 -55°C 到 110°C,使得它能够在极端环境条件下正常工作,具备卓越的温度稳定性,非常适合用于温差较大的工业和户外应用场合。这种耐受性使得它在无人值守的设备、传感器及其他关键设施中得以广泛应用。
封装与安装
IS281GR 采用专用的 4-SOIC(0.173", 4.40mm 宽)封装,便于表面贴装。这种封装设计不仅节省了 PCB空间,还提升了组装的自动化程度,使得产品的生产效率和可靠性得以提高。对于现代电子设备设计师来说,该光耦的封装与安装方式为其在设计中引入了更大的灵活性和便捷性。
应用场景
由于其出色的电气和环境特性,IS281GR 广泛应用于各种领域,包括但不限于:
总体而言,IS281GR 是一种高效、安全、可靠的光电耦合器,具备卓越的电气特性和环境适应能力,特别适合于现代电子产品的设计需求。无论是在严苛的工业环境还是高要求的消费市场,IS281GR 都能为设计师和工程师提供稳定的解决方案,使其在瞬息万变的电子市场中牢牢占据一席之地。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
