EL817(C)-G 产品概述
一、产品简介
EL817(C)-G 是台湾亿光（EVERLIGHT）推出的一款晶体管输出光耦合器，采用 DIP-4 封装，输入为直流（DC）发光二极管，输出为光电三极管。器件用于实现信号和电源回路之间的电气隔离，适合需要高隔离电压与较大输出驱动能力的场合。
二、主要特点
- 隔离耐压高：最大隔离电压可达 5 kVrms，适合工业与电源侧的隔离防护需求。
- 宽广的电流传输比（CTR）：最小 50%，饱和值可达 600%，在不同工作点下能提供灵活的增益余量。
- 输出能力强：最大输出电流可达 50 mA，负载电压最高 35 V，适用于驱动下游晶体管或逻辑输入。
- 低饱和压：集射极饱和电压 VCE(sat) ≈ 100 mV（典型工况），有利于降低导通损耗。
- 工作温度范围宽：-55 ℃ 至 +110 ℃，适合严苛环境使用。
- 响应速度中等：上升/下降时间约 18 µs，适合一般控制与信号隔离，但非高速数字通信专用。
三、关键规格（主要参数一览）
- 隔离电压 (Vrms)：5 kV
- 输入类型：DC（发光二极管）
- 正向压降 (Vf)：约 1.2 V（典型）
- 正向电流 (If)：最大 60 mA
- 直流反向耐压 (Vr)：6 V
- 电流传输比 (CTR)：最小 50%，最大/饱和值 600%
- 输出类型：光电三极管
- 最大输出电流：50 mA
- 负载电压：35 V
- 集射极饱和电压 VCE(sat)：约 100 mV（指定测试条件下）
- 上升/下降时间：约 18 µs
- 总功耗 Pd：200 mW
- 输出通道数：1
- 封装：DIP-4
- 工作温度：-55 ℃ ～ +110 ℃
四、典型应用
- 工业控制与传感器信号隔离
- 电源管理与开关电源的信号反馈隔离
- 微控制器与高电压电路之间的接口保护
- 家电、通信设备中低速数字隔离
- 需要中等响应速度与较高隔离耐压的系统
五、设计与使用建议
- 根据实际工作点选择合适的输入限流电阻，以限制 If ≤ 60 mA 并获得期望 CTR。
- CTR 受温度与批次影响较大，设计时应考虑最小 CTR（50%）的最坏情形，保证在最不利条件下仍能满足逻辑阈值或驱动需求。
- 输出为光电三极管，若需更低饱和压或更快切换，可通过后级放大或加速电路优化。
- 注意封装散热与总功耗 Pd（200 mW）限制，长期高 If/高 Ic 工况需留有余量。
- 在高压隔离应用中，遵守爬电距离、绝缘材料和工艺要求，以确保长期可靠性。
EL817(C)-G 以其高隔离电压、较大输出能力和宽温度范围，适合在工业与电源类产品中作为可靠的信号隔离元件。根据系统需求合理选型与电路设计，可充分发挥其性能优势。

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.
