6N137-500E 产品概述

一、产品简介

6N137-500E 是 Broadcom(博通)推出的一款高速光隔离器,集成逻辑输出级并采用肖特基箝位与开集电极输出结构,面向需要高共模抑制和快速数字隔离的系统。器件支持典型5V工作电源(推荐工作电压 4.5V~5.5V),单通道设计,适合微处理器接口、总线隔离和工业控制领域的数字信号隔离需求。

二、主要性能参数

  • 隔离耐压(典型):3750 Vrms(部分应用环境或认证要求下可标称更高等级,请参见具体器件认证资料)
  • 共模瞬态抗扰度(CMTI):10 kV/µs(高抗扰能力,适合高速脉冲环境)
  • 传输速率:10 Mbps(适用于大多数高速数字接口)
  • 通道数:1
  • 工作温度:-40 ℃ ~ +85 ℃
  • 工作电压(VCC):4.5V ~ 5.5V
  • 传播延迟:tpLH ≈ 25 ns;tpHL ≈ 48 ns
  • 输入参数:正向电压 Vf ≈ 1.5V;正向电流 If(最大推荐)≈ 20 mA;输入阈值电流(FH)≈ 5 mA
  • 输出参数:开集电极输出,最大输出电流可达 50 mA(外部上拉电阻与功率限制需按应用选型)
  • 输入反向耐压 Vr ≈ 5V

三、封装与引脚

器件采用 SOIC-8 封装,鸥翼引脚(gull-wing)设计,便于自动贴装与波峰/回流焊接。输出为开集电极结构,需外接上拉电阻至 VCC;内部含肖特基箝位以提高切换速度并降低负载反向恢复影响。引脚排列与标准 6N137 系列兼容,便于产品替换与设计复用。

四、典型应用

  • MCU/FPGA 与不共地外设之间的数字隔离
  • 高速串行接口隔离(某些低延迟串行链路、控制信号)
  • 工业现场总线与测控系统的信号隔离
  • 电机驱动、逆变器等高噪声环境下的控制信号隔离
  • 医疗设备、安防与通信设备中需要符合隔离规范的场景

五、使用建议与注意事项

  • 输出为开集电极,设计时必须配置合适的上拉电阻以满足速度与电流要求;较小的上拉阻值可提高上升沿速度,但会增加功耗。
  • 为保证抗扰度与低延迟,应将 VCC 旁路电容靠近器件 VCC 与 GND 引脚放置,推荐 0.1 µF 高频陶瓷旁路。
  • 布局时保持输入侧与输出侧的爬电距离与间隙,避免穿越导体形成泄漏通道;遵循相关安全与电气隔离规范。
  • 输入 LED 正向电流应控制在推荐值内(If ≤ 20 mA),并考虑反向电压保护措施(Vr ≈ 5V)。
  • 在强共模干扰场景下,结合差分传输或滤波方案以进一步提高系统鲁棒性。

6N137-500E 以其快速传输、较高 CMTI 与标准化封装,适合需要可靠数字隔离且对延迟和抗扰度有较高要求的电子系统。购买与设计前请参考 Broadcom 官方数据手册与应用说明以获取完整电气特性与验证条件。

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.

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
