XEL357C-TAG 光电耦合器产品概述
一、产品定位与核心价值
XEL357C-TAG是芯伯乐（XBLW）推出的工业级DC输入光电三极管输出耦合器，专为需要高电气隔离、宽温度范围和稳定信号传输的场景设计。产品核心价值在于平衡了高电流传输比（CTR）、快速响应速度与宽温可靠性，可有效实现输入输出端的电气隔离，同时保障信号的准确传输，适用于工业自动化、汽车电子、通信等多领域的信号隔离需求。
二、关键参数与性能优势
1. 电气传输性能
- 输入侧：DC输入，正向压降Vf=1.2V（稳定导通电压，减少驱动功耗）；正向电流If最大50mA（安全驱动范围宽）；直流反向耐压Vr=6V（防止反向电流损坏）。
- 输出侧：光电三极管输出，输出电流最大50mA（具备较强负载驱动能力）；负载电压最大70V（输出端耐压满足多数应用场景）；集射极饱和电压VCE(sat)仅100mV（当Ic=20mA或1mA时），大幅降低输出端功耗，提升效率。
- 传输特性：CTR最小值200%、最大值400%，宽温范围内保持稳定，减少驱动电流需求；响应速度快（tr=4μs、tf=3μs），适合中高速信号传输。
2. 隔离与可靠性
- 隔离电压：Vrms=3.75kV（有效值），满足工业级高隔离需求，阻断输入输出端电气干扰；
- 工作温度：-55℃~+110℃，覆盖极端环境（如工业现场、汽车发动机舱），适应严苛工况。
三、封装与工艺设计
XEL357C-TAG采用SOP-4-2.54mm标准封装，引脚间距2.54mm，符合行业通用贴装规范，支持自动化回流焊与手工焊接，便于批量生产与现场调试。封装材料选用耐高温、抗老化工程塑料，配合优化的内部隔离层工艺，确保宽温范围内隔离性能稳定，同时提升机械强度与抗冲击能力。
四、典型应用场景
- 工业自动化：PLC输入输出模块隔离（阻断现场干扰）、传感器信号隔离（保护控制器）；
- 汽车电子：车载传感器（温度/压力）信号隔离（适应-40℃~+125℃波动）、车载总线隔离（提升抗干扰）；
- 通信设备：光纤收发器信号隔离（阻断地环路干扰）、电源反馈回路隔离（提升系统稳定）；
- 医疗设备：监护仪/呼吸机信号隔离（满足电气安全要求，防止电击风险）。
五、应用注意事项
- 电气限制：If≤50mA、Vr≤6V、输出负载电压≤70V，避免过流/过压损坏；
- 焊接与存储：焊接温度≤260℃（回流焊时间≤10s）；存储环境：0℃~+40℃、湿度≤85%RH；
- CTR调整：CTR随温度略有变化，但-55℃~+110℃内仍保持200%以上最小值，可根据温度适当调整驱动电流。
XEL357C-TAG凭借高隔离、宽温、高CTR等特性，成为工业与汽车领域信号隔离的高性价比选择。

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.
