6N137-000E 产品概述

一、概述

6N137-000E 是 Broadcom(博通)出品的一款高速光隔离器,单通道逻辑输出,适用于直流输入接口及高速数字信号隔离。器件提供高达 3750 Vrms 的隔离电压和典型 10 kV/µs 的共模瞬变抗扰度(CMTI),传输速率可达 10 Mbps,常用于需要高速度与高电气隔离的系统中,如微控制器接口、工业总线和电源域隔离等。

二、主要规格与特性

  • 输入类型:DC(LED 驱动)
  • 工作电压(VCC):4.5 V ~ 5.5 V
  • 隔离电压:3.75 kVrms
  • CMTI:10 kV/µs(典型)
  • 传输速率:10 Mbps
  • 通道数:1
  • 工作温度:-40 ℃ ~ +85 ℃
  • 传播延迟:tpLH ≈ 75 ns,tpHL ≈ 75 ns
  • 输入阈值电流(FH):5 mA(确保逻辑切换)
  • 输出电流:最大 50 mA(短时)
  • 器件耗散功率 Pd:85 mW(器件总体功耗限制)
  • LED 正向压降 Vf:约 1.4 V
  • LED 直流反向耐压 Vr:5 V
  • 封装:8 引脚 DIP

三、封装与引脚注意

6N137-000E 常见为 8-DIP 封装,便于插装与测试。输出为开集电极(open-collector),需要外部上拉电阻到 VCC 来形成逻辑高电平;器件内部含肖特基箝位以减少输出存储效应并加快翻转速度。设计时请查阅具体引脚图并做好 VCC 去耦(典型 0.01 µF 至 0.1 µF)以保证稳定工作。

四、工作原理与典型电路

输入侧为 LED,驱动电流需保证至少达到输入阈值以便可靠切换(建议典型工作电流略高于 5 mA,根据速度要求可适当增大)。输出侧为开集电极光敏晶体管,输出上拉电阻决定上升时间与输出功耗:较小的上拉阻值可以减少上升延迟但增大器件耗散,建议根据 10 Mbps 的速率选择适当阻值并注意输出器件的 Pd 限制。肖特基箝位可限制输出饱和电压,改善翻转延迟与复位时间。

五、应用场景与选型建议

适用于:

  • 微控制器与高速数字接口隔离(UART、SPI 时钟/数据线隔离)
  • 工业控制信号隔离、PLC 接口、伺服驱动信号隔离
  • 电源域分离、防止地环路引起的信号干扰
  • 需要高 CMTI 的环境(大电流开关或电机驱动附近)

选型建议:

  • 若工作速率接近 10 Mbps,应注意输入驱动强度与输出上拉设计以满足时序。
  • 若长期大电流下工作,建议采用更低的占空比或外部限流和散热措施,避免超过 Pd 额定。

六、设计注意事项与热管理

  • LED 反向电压 Vr 为 5 V,避免反向超过该值;输入端应加反向保护或限流电阻。
  • 输出虽能短时承受 50 mA,但长期工作建议限流至较低值以减少功耗与温升。
  • 器件 Pd 为 85 mW,应在 PCB 布局上预留散热路径并避免紧邻高温元件,必要时进行热仿真与降额设计。
  • 高频或高共模干扰环境下,注意保持输入与输出地的合理分离并添加适当的滤波与去耦元件。

总结:6N137-000E 提供高速、可靠的电气隔离与优异的共模瞬变抗扰能力,适合对速度与隔离等级有较高要求的数字信号隔离应用。按照器件推荐的驱动条件与热管理措施设计,能够获得稳定且长期可靠的隔离性能。

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
