SL247N 光耦合器件产品概述

一、概述

SL247N 是 Slkor(萨科微)出品的一款四通道光电三极管输出光耦,封装为 SSOP-16,适用于需要电气隔离的数字与模拟信号耦合场合。器件采用高隔离设计,典型隔离耐压 3.75 kVrms,工作温度范围宽(-55℃ ~ +110℃),在工业控制、电源反馈、通信接口和微控制器隔离等领域具有良好适配性。

二、主要电气参数

  • 输入类型:DC(LED 驱动)
  • 正向压降 Vf:1.2 V(典型)
  • 正向电流 If:最大 50 mA(单通道)
  • 输出类型:光电三极管
  • 输出电流:50 mA(最大)
  • 负载电压(耐压):80 V(集电极对发射极最大承受)
  • 直流反向耐压 Vr(LED 反向):6 V
  • 隔离电压 Vrms:3.75 kV
  • 电流传输比 CTR:最小 50%,最大/饱和值 600%(随 If 与温度变化)
  • 集—射极饱和电压 VCE(sat):约 100 mV(在指定测试电流下,如 1 mA 或 10 mA)
  • 上升时间 tr:5 µs(在 2 mA、100 Ω 负载条件下)
  • 下降时间 tf:3 µs
  • 输出通道数:4(独立通道)
  • 封装:SSOP-16

三、特点与优势

  • 四通道集成,节省 PCB 面积并便于信号集中处理。
  • 高隔离电压(3.75 kVrms),满足多数工业级隔离需求。
  • 宽负载电压能力(最高 80 V),适配不同逻辑与工业电平。
  • 低 VCE(sat) 带来较小的输出压降和热耗,适合需要低功耗的接口。
  • CTR 范围宽,适用多种驱动电流下的增益需求;响应时间适中,满足典型的开关与数字隔离速度要求。

四、典型应用

  • 开关电源反馈隔离(次级到主控信号)
  • 工业控制信号隔离(PLC、驱动模块)
  • 微控制器 / 总线隔离(UART、I2C 附带隔离需求时可用)
  • 仪器仪表、通信设备和电力电子保护电路

五、设计与使用建议

  • 驱动 LED 时按 R = (Vdrive - Vf) / If 计算限流电阻,注意 Vf 取 1.2 V 典型值并留裕量;若需精确 CTR 设计,应以最小 CTR(50%)作为保守值计算。举例:若需输出 1 mA(IC),按 CTR 50% 则需 If ≈ 2 mA。
  • 当输出端上拉到较高电压(可达 80 V)时,选择合适阻值并注意限功率与电阻耐压。高电压场合建议采用分压/限流与器件额定功率核算。
  • 布局时保持输入与输出侧良好爬电距离与走线空隙,遵守隔离等级设计准则;为提高 EMC 性能,可在输入侧并联去耦或 RC 抑制网络。
  • 工作温度范围广,但在高温与高 If 条件下需注意器件自热与长时可靠性,必要时对 If 进行热降额。
  • 若系统对速度要求较高,应通过提高 If 提升 CTR 并缩短上升下降时间,但需在最大 If 限值内权衡功耗与寿命。

SL247N 以其四通道集成、高隔离与宽负载能力,适合多种工业与消费类电路的信号隔离需求。正常设计与良好 Layout 可发挥其低饱和压降与高 CTR 的优势,达到稳定可靠的隔离传输效果。

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
