HCPL-181-00CE 产品概述

一、概述

HCPL-181-00CE 是 Broadcom(博通)出品的一款单通道光隔离器,输入端为直流 LED,输出端为光电三极管。器件采用微型 SOP-4 封装(2.54mm 间距、Mini-Flat 风格),提供高达 3.75 kVrms 的隔离电压,适用于信号隔离、逻辑接口和低速开关隔离等场合。器件设计注重高隔离性能与紧凑封装的结合,便于电路板空间受限但对隔离要求高的系统设计。

二、主要特性

  • 单通道光隔离输出(光电三极管)
  • 隔离耐压:3.75 kVrms
  • 正向压降(Vf):约 1.2 V
  • 正向电流(If)额定可达 50 mA
  • 输出电流最大 50 mA,负载耐压最高可到 80 V
  • 直流反向耐压(Vr):6 V
  • 集电极—发射极饱和电压 VCE(sat):典型 200 mV(在 1 mA 和 20 mA 条件下测量)
  • 上升时间 tr:约 4 μs(测量条件:If=2 mA、RL=100 Ω)
  • 下降时间 tf:约 3 μs
  • 电流传输比(CTR)最小值:50%
  • 工作环境温度:-55 ℃ 至 +100 ℃

三、关键参数说明

  • 隔离电压(3.75 kVrms):用于保证输入侧与输出侧在高电压差情况下的安全隔离,适合电源隔离、工业控制和电网接口等场景。
  • CTR(≥50%):指在特定 If 下输出集电极电流与输入正向电流的比率,决定了所需输入电流大小以驱动输出,设计时需根据目标输出电流选定 If。
  • 开关速度(tr/tf ≈ 3–4 μs):该器件属于低到中速类型,适合脉冲宽度较长或速率不高的数字信号隔离,不适合高频率或严格时序的高速总线隔离。

四、封装与引脚

器件采用 SOP-4(Mini-Flat)封装,间距 2.54 mm,单通道设计便于在狭小 PCB 面积内实现隔离功能。典型应用中,输入侧外接限流电阻以保护 LED,输出侧常用上拉电阻或与下游电路直接耦合(需注意最大集电极电压 80 V 和输出电流限制)。

五、设计与使用建议

  • 输入限流电阻计算:R = (Vdrive - Vf) / If。示例:在 5 V 驱动、目标 If=2 mA 时,R ≈ (5 − 1.2) / 2 mA ≈ 1.9 kΩ。为保证长期可靠性及 CTR 需要,可适当增加裕量或按实际需求调整 If。
  • 输出负载与速度权衡:较小的上拉电阻可获得更低的上升时间,但会增加输出电流和功耗;速度要求不高时推荐使用较大阻值以降低功耗。
  • 热与寿命:If 峰值不得超过器件额定 50 mA,长时间高 If 会升高结温,建议在 PCB 布局中考虑散热和功率分配。
  • 隔离区布线:保持输入侧与输出侧的焊盘和走线间足够的爬电/空气间隙,遵守系统的安全规范以发挥 3.75 kVrms 隔离性能。

六、典型应用场景

  • 工业控制信号隔离(PLC 输入/输出、继电器驱动隔离)
  • 电源供应控制与反馈隔离(如开关电源次级到控制端的隔离)
  • 微控制器与高电压侧之间的逻辑隔离
  • 家电和消费电子中的低速数字隔离

七、可靠性与环境适应

工作温度范围宽(-55 ℃ 至 +100 ℃),适应工业级工况。在设计中应关注长期热应力和输入电流的限制,严格遵守最大额定电压和功率条件以延长使用寿命。

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
