EL817S1(D)(TU)-G 产品概述
一、简介
EL817S1(D)(TU)-G 是台湾亿光（EVERLIGHT）推出的一款单通道晶体管输出光电耦合器，输入为直流 LED，输出为光电三极管。该器件以高隔离电压、宽工作温度和较低饱和电压为主要特点，适用于信号隔离与电平转换场合。
二、主要参数
- 输入类型：DC（发光二极管）
- 输出类型：光电三极管（晶体管输出）
- 正向压降 (Vf)：1.2 V
- 正向电流 (If)：最高 60 mA（使用时应参考安全工作区）
- 输出电流：50 mA
- 隔离电压 (Vrms)：5 kV
- 直流反向耐压 (Vr)：6 V
- 负载电压：35 V
- 输出通道数：1 通道
- 集射极饱和电压 VCE(sat)：100 mV（标称条件：20 mA，1 mA 说明于规格书）
- 上升/下降时间（tr/tf）：18 µs / 18 µs
- 工作温度范围：-55 ℃～+110 ℃
- 电流传输比 (CTR)：最小 50%，最大（饱和值）600%
- 总功耗 (Pd)：200 mW
- 封装：SOP-4，2.54 mm 间距
三、主要特点
- 高隔离强度：5 kV RMS 隔离等级，保障信号侧与电源侧的绝缘安全。
- 宽 CTR 范围：50%~600%，适应不同增益需求（请按测试条件选型）。
- 低饱和电压：集电极-发射极饱和电压低至约 100 mV，有利于降低开关损耗。
- 中速响应：上升/下降时间约 18 µs，适合一般控制与信号传输场景。
- 宽温度适应性：工作温度覆盖工业级应用需求。
四、典型应用
- MCU/单片机与高压回路之间的信号隔离与接口驱动
- 开关电源的反馈与隔离检测
- 中小功率继电器、继电器驱动电路的前端隔离
- 工业控制、仪表和通信设备的接口保护
五、使用建议与注意事项
- 输入侧应控制 If 在安全范围内（参考最大 60 mA），短时允许但应避免长期过驱动导致寿命下降。
- 输出侧负载电压不得超过 35 V，集电极电流请勿超过 50 mA，以免超出功耗限值（Pd 200 mW）。
- 注意正向反向电压限制：LED 反向耐压 Vr = 6 V，不可反向施加高压。
- 设计时应按规格书选取合适的上拉/下拉电阻以获得所需响应速度与 CTR；较大的负载电阻会降低输出电流与速度。
- 保持器件工作环境在额定温度范围内，并注意焊接与回流工艺参数以避免封装热损伤。
- 若用于高隔离系统，建议按标准进行耐压/绝缘测试并预留足够爬电距离。
六、封装信息
- 封装形式：SOP-4（2.54 mm 引脚间距），单通道封装，便于 PCB 布局与批量生产组装。
如需更详细的电气特性曲线、典型应用电路或封装尺寸图，建议参考 EVERLIGHT 官方规格书与器件参数表以获得精确测试条件与限值说明。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
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.
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.
