HCPL-0701-500E 产品概述

HCPL-0701-500E 为 Broadcom(博通)推出的一款高隔离、单通道光隔离器,采用 SO-8 封装,输出为带基极的达林顿光电晶体管。器件专为需要高增益、低输入驱动电流以及强隔离性能的信号传输场合设计,广泛用于开关电源、电机驱动、微控制器接口和工业控制系统中的逻辑隔离与电平转换。

一、主要规格

  • 输入类型:DC(LED 驱动)
  • 正向压降 (Vf):典型 1.4 V(If = 12 mA)
  • 标称正向电流 (If):12 mA(用于 CTR 规格测量)
  • 电流传输比 (CTR):最小 400%,最大/饱和值 5000%(高增益达林顿结构)
  • 输出类型:带基极的达林顿光电晶体管,单通道
  • 最大输出电流:60 mA
  • 负载电压(最大 Vce):18 V
  • 隔离电压:3750 Vrms(绝缘可靠,可用于高压隔离场合)
  • 直流反向耐压 (Vr):5 V(LED 端)
  • 总功耗 Pd:135 mW
  • 工作温度范围:0 ℃ ~ +70 ℃
  • 封装:SO-8(8 引脚)

二、关键性能与特点

  • 高隔离等级(3.75 kVrms),适合需要安全隔离与高共模抑制的系统设计;满足医疗、工业及电源隔离应用的可靠性要求。
  • 达林顿输出结构带来极高的电流放大倍数(CTR),可在较小输入驱动电流下输出较大的集电极电流,便于驱动高电平负载或减少 MCU/驱动器的负担。
  • 器件提供基极引脚,便于通过外部电阻或电路对输出晶体管进行开速、关断或偏置控制,改善响应速度或实现闭锁控制。
  • SO-8 紧凑封装,便于通用 PCB 布局与波峰/回流焊工艺。

三、典型应用场景

  • 隔离式开关电源反馈与控制信号传输。
  • 工业控制器与可编程逻辑控制器(PLC)输入/输出隔离。
  • 电机驱动与逆变器的逻辑隔离与故障检测回路。
  • 微控制器与高电压电路之间的安全隔离接口。

四、封装与引脚提示

  • 采用 SO-8 8 引脚封装,单通道光耦设计,包含 LED 阳极/阴极、达林顿晶体管的集电极/发射极与基极引出。
  • 设计 PCB 时建议在输入侧与输出侧保持足够的爬电距离与电气隔离区,并在封装周围预留散热回流路径以保证 Pd 限值内运行。

五、设计与使用注意事项

  • 由于 CTR 范围较宽(400%–5000%),在系统设计应以最小 CTR(400%)进行最坏情况计算,实际样品需验证以保证可靠性。
  • 达林顿输出的饱和电压相对较高,开关时输出“低”电平会有一定压降,设计上需考虑负载电压余量与功耗。
  • 注意总功耗 135 mW 限制,避免在高环境温度或大电流下长期工作;必要时采用降温或限制输出占空比。
  • 输入端请避免超过 5 V 的反向电压,以保护 LED。若需高速切换,可在基极/集电极加速放电路径以改善关断时间。

HCPL-0701-500E 以其高隔离、电流放大能力和基极可控特性,适合在对隔离等级和驱动能力有较高要求的工业与电源应用中使用。设计时结合最小 CTR、Pd、工作温度与封装布局进行验证,可获得稳定可靠的隔离信号传输。

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
