HCNR201-550E 产品概述

一、概述

HCNR201-550E 是一款用于精密隔离测量的线性光电耦合器(Optocoupler),由 Broadcom(博通)推出。器件以发光二极管(LED)作为输入、光电二极管作为输出,提供高线性度的电流传输特性与高电气隔离能力,适合在高压隔离测量、精密反馈和仪表放大等场景中替代变压器或复杂隔离放大器方案。

二、主要电气参数

  • 输入类型:AC / DC 驱动均可
  • 输出类型:光电二极管(电流输出)
  • 正向压降 Vf:约 1.6 V(If = 10 mA 条件)
  • 隔离电压 Vrms:5 kV(工频绝缘等级)
  • 直流反向耐压 Vr:2.5 V
  • 输出通道数:1 路
  • 工作温度:-40 ℃ ~ +85 ℃
  • 电流传输比(CTR):最小 95%,最大/饱和值 105%
  • 总功耗 Pd:60 mW
  • 推荐正向电流 If:10 mA
  • 封装:SOP-8(引脚间距 2.54 mm)

三、产品特点与优势

  • 高线性度:95%–105% 的 CTR 范围保证了光电输出与输入电流之间的良好线性对应,便于与运放构成精密隔离放大器。
  • 强绝缘性能:5 kVrms 的隔离等级满足多数工业与电力电子应用对安全隔离的需求,可实现低侧与高侧、控制与功率间的可靠隔离。
  • 宽温度工作区:-40~+85 ℃ 的温度范围适应工业级环境。
  • 低功耗与小封装:60 mW 的总功耗与 SOP-8 小封装,有利于在空间受限的电路板上实现隔离功能。
  • 通用输入兼容性:支持 AC 与 DC 驱动,适配多种检测与反馈场景。

四、典型应用

  • 开关电源(SMPS)反馈回路的隔离型线性传输;替代光耦+TL431 等组合实现无变压器的反馈隔离。
  • 精密电流/电压测量隔离:作为光电隔离前端,搭配运放做跨阻或差分放大,适用于工业测量仪表。
  • 光伏逆变器与高压测控:用于光伏阵列或逆变器中高压侧与控制侧的信号传递与测量。
  • 隔离型 ADC 前端、数据采集模块、绝缘监测等需要线性隔离的场合。

五、使用建议与注意事项

  • 驱动与偏置:建议在 If ≈ 10 mA 附近工作以获得标称 CTR 与线性性能,驱动电路应使用合适的限流电阻并考虑温漂影响。
  • 放大器配置:输出光电二极管通常与跨阻放大器(TIA)或差分放大器配合使用,以实现电流—电压的线性转换及增益稳定。对于最高精度应用建议做温度补偿与校准。
  • 散热与功耗限制:器件 Pd 为 60 mW,应注意在高温环境下的功率降额,确保封装温升与焊盘热阻在安全范围内。
  • 安全与布局:尽量保证输入与输出端的爬电距离和间隙满足系统电压等级要求,隔离测试时遵循制造商的试验规范(5 kVrms)。
  • 反向电压保护:输出端光电二极管的直流反向耐压为 2.5 V,电路设计时应避免超过该值以防损坏。

六、封装与采购提示

HCNR201-550E 常见封装为 SOP-8(引脚间距 2.54 mm),便于常规 SMT/通孔混装工艺。订购时请确认完整型号与包装形式,并核对 Datasheet 中的典型特性曲线与应用电路,以便在目标系统中获得预期的线性度与隔离性能。

总结:HCNR201-550E 以其高线性 CTR、5 kV 绝缘能力与工业级工作温度,适合用于对精度与安全隔离有较高要求的测量与反馈场合。正确的偏置、放大器选择与热管理能最大限度发挥其性能。

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.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
