EL3H7C 光电耦合器 产品概述
一、产品简介
EL3H7C 为 AOTE（奥特）出品的高增益单通道光电耦合器，输入为直流驱动的发光二极管（LED），输出为光电三极管。器件在保持高隔离电压的同时，提供宽范围的电流传输比和较快的开关速度，适用于信号隔离与电平转换场合。
二、主要特性
- 隔离耐压：3.75 kVrms，满足常见工业隔离需求。
- 电流传输比（CTR）：典型较高，最小200%，最大可达400%，适合低驱动电流场景。
- 输出能力：输出电流可达50 mA，最大承受负载电压80 V。
- 正向压降：LED Vf ≈ 1.2 V（典型）。正向电流 If 最大50 mA。
- 集射极饱和电压：VCE(sat)≈200 mV（标注条件下，例如 1 mA~10 mA）。
- 开关特性：上升时间 tr ≈ 3 µs（在 If=2 mA、RL=100 Ω 条件），下降时间 tf ≈ 2 µs。
- 工作温度：-55 ℃ ~ +110 ℃。
- 封装：SSOP-4，单通道，适合表面贴装工艺。
三、电气与可靠性要点
- 直流反向耐压 Vr（LED）约为 6 V，请勿反向长期加压。
- 输出端允许的最大负载电压为 80 V，但应按应用中实际功率与散热条件配置限制电流的外部元件。
- 高 CTR 有利于降低驱动功耗，但在不同 If 条件下 CTR 波动较大，设计时应按最小 CTR（200%）进行裕量计算。
- 隔离结构适合信号隔离、微弱信号传输及控制接口的安全隔离设计。
四、典型应用
- 工业控制信号隔离（PLC、驱动板输入输出隔离）
- 微控制器与高压电路之间的水平隔离与电平转换
- 电源管理与保护电路中的故障/状态信号传递
- 模拟或数字接口的抗干扰隔离
五、封装与引脚（典型）
- 封装：SSOP-4，外形小巧，支持自动贴片。
- 典型引脚（SSOP-4 单通道）：引脚1 LED 阳极（A），引脚2 LED 阴极（K），引脚3 发射极（E），引脚4 集电极（C）。（请参照最终器件数据手册确认实际管脚排列与焊盘尺寸）
六、使用建议
- 输入侧加限流电阻，确保 LED 电流不超过 If=50 mA 并留有裕量；若追求最快响应速度，可在中等 If 下选用合适 RL。
- 输出侧常用开集电极配置，外接上拉电阻到所需逻辑电平，注意负载电压与器件承受能力（≤80 V）。
- 设计时以最低 CTR（200%）和最高工作温度下的性能退化为依据进行裕量设计，保证稳定可靠。
- 如需符合特定安规，请参照完整规格书和应用手册进行安规距离与封装处理。
EL3H7C 以其高 CTR、较高隔离电压与通用化封装，适合对驱动能力、隔离性能和成本有综合考虑的工业与消费电子场景。若需完整电气特性、定量曲线与封装尺寸，请索取 AOTE 官方数据手册。

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.
