ELR2223双向可控硅输出光电耦合器产品概述

一、产品定位与核心身份

ELR2223是台湾亿光电子(EVERLIGHT)推出的单通道双向可控硅输出型光电耦合器,属于光电器件领域的隔离控制核心组件。其核心功能是通过光信号实现高低压电路的电气隔离,内部集成双向可控硅作为输出端,兼具“光隔离抗干扰”与“可控硅无触点开关”双重特性,可替代传统机械继电器,解决高压负载与低压控制电路之间的绝缘安全、电磁耦合问题。

二、关键电气参数解析

ELR2223的电气参数直接决定其适用场景,核心参数需重点关注:

1. 隔离安全指标

  • 隔离电压(Vrms):5kV(交流有效值),是产品最核心的隔离指标,可有效阻断高低压电路的电气导通,保障低压控制端(如MCU、PLC)与高压负载端(如电机、加热元件)的安全隔离,满足工业级高压场景需求。

2. 可控硅输出特性

  • 输出电流(It(rms)):900mA(有效值),为产品可驱动的最大负载电流(交流/直流负载需匹配);
  • 负载电压:600V,输出端最大可承受的负载电压,覆盖多数中高压应用(如220V/380V交流负载);
  • 保持电流(Ih):25mA,可控硅导通后需维持的最小电流,若负载电流低于此值,可控硅将自动关断;
  • 静态dv/dt:200V/μs,抗电压变化率能力,可避免负载端电压突变(如开关浪涌)导致的可控硅误触发,提升电路稳定性。

3. 输入端驱动参数

  • 正向压降(Vf):1.2V(输入端LED的正向压降);
  • 最大正向电流(If):60mA,输入端LED的极限电流,实际使用需串联限流电阻,避免过流烧毁。

4. 环境与通道特性

  • 通道数:1通道,单路独立控制,便于多路扩展;
  • 工作温度范围:-40℃~+85℃,宽温范围适配户外设备、工业现场等极端环境。

三、机械与封装特性

ELR2223采用DIP-8双列直插式封装,符合工业通用规范:

  • 端子数:8引脚,引脚定义遵循亿光官方 datasheet(通常输入端LED占2引脚,输出可控硅占4引脚,剩余为辅助引脚);
  • 尺寸兼容性:标准DIP-8封装尺寸,可直接匹配多数PCB板的通孔设计,便于手工组装与批量生产;
  • 焊接可靠性:通孔封装焊接牢固,抗振动能力优于贴片封装,适用于振动环境的工业设备(如机床、风机)。

四、典型应用场景

ELR2223凭借“高压隔离+无触点开关”的优势,广泛应用于以下领域:

  1. 工业控制:PLC输入输出模块、电机软启动控制、继电器替代(如替代电磁继电器驱动电磁阀);
  2. 家电产品:空调压缩机控制、洗衣机加热元件驱动、冰箱电磁阀切换;
  3. 通信设备:电源模块隔离控制、基站信号切换单元;
  4. 照明领域:LED驱动隔离调光、荧光灯镇流器高压控制;
  5. 安防设备:门禁电锁驱动、报警装置高压触发。

五、选型与使用注意事项

为保障产品可靠性,使用时需注意以下要点:

  1. 参数匹配:负载电流≤900mA(rms)、负载电压≤600V,避免过流过压损坏;
  2. 输入端限流:串联限流电阻计算:( R = \frac{V_{cc} - V_f}{I_f} )(例:Vcc=5V、If=20mA时,R≈190Ω,选200Ω标准电阻);
  3. 保持电流保障:导通后负载电流需≥25mA,否则可控硅关断;
  4. 静电防护:半导体器件需注意ESD防护,焊接时使用防静电烙铁与工作台;
  5. 引脚连接:严格按官方datasheet引脚定义连接,避免错接(如输入端LED正负极接反)。

六、产品优势总结

ELR2223的核心优势包括:

  • 高隔离安全:5kV隔离电压满足工业级高压隔离需求;
  • 无触点长寿命:可控硅无机械触点,寿命远高于机械继电器(无磨损、无触点氧化问题);
  • 宽温适配:-40℃~+85℃覆盖多数应用环境;
  • 亿光品质:台湾亿光的专业光电器件制造工艺,符合RoHS环保标准,可靠性有保障。

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.
