SSP5842ED 产品概述

一、产品简介

SSP5842ED 是上海矽朋(Siproin)推出的一款高速数字隔离器,提供安全可靠的信号隔离方案。器件在单片 SOIC-16-300mil 封装内实现 2 路正向(A→B)和 2 路反向(B→A)数字通道,适用于需要隔离数据信号的工业与通信场景。

二、主要特性

  • 通道数:2 路正向 + 2 路反向(共 4 路独立数字通道)
  • 最高数据速率:150 Mbps
  • 默认输出电平:高电平(默认复位状态)
  • 隔离电压(Vrms):5000 Vrms(系统级隔离能力)
  • 共模瞬变抗扰度(CMTI):50 kV/μs
  • 工作温度范围:-40 ℃ 至 +125 ℃
  • 工作电压:VCCA = 2.5 V ~ 5.5 V,VCCB = 2.5 V ~ 5.5 V
  • 传播延迟(tpd):典型 9 ns
  • 封装:SOIC-16-300mil

三、性能与优势

SSP5842ED 在保持高隔离电压的同时提供高共模抑制能力(50 kV/μs),能有效抵抗快速变换的共模干扰。9 ns 的低传播延迟与 150 Mbps 的带宽使其适合时延敏感的数字链路。双供电域设计(VCCA/VCCB 可接不同电压等级)提高了系统互联的灵活性。默认输出为高电平,有利于保证隔离链路在上电或失能时处于已知安全状态。

四、典型应用

  • 工业现场总线与传感器隔离(如 RS-485、SPI、UART 等数字接口的隔离)
  • 电力电子与逆变器控制信号隔离
  • 医疗设备信号隔离(符合高隔离等级要求的低压侧/高压侧隔离)
  • 通信设备与测试测量仪器中的隔离数据通道

五、设计建议

  • 在 VCCA/VCCB 引脚附近各放置 0.1 μF 陶瓷去耦电容,靠近封装引脚焊盘以降低寄生感抗。
  • 布局时保证隔离区的爬电距离和气隙满足系统安全标准,并注意走线不要穿越隔离缝隙。
  • 对于高共模干扰环境,配合差分走线、滤波或共模电感以提高系统抗干扰性。
  • 依据默认高电平特性,考虑上电顺序与上拉策略,避免产生意外脉冲或不确定态。

六、封装与可靠性

SSP5842ED 提供 SOIC-16-300mil 封装,便于通用 PCB 工艺安装与批量生产。器件支持工业级温度范围(-40 ℃ 至 +125 ℃),并具备 5 kVrms 隔离能力,满足多数工业与电力电子应用的安全和可靠性要求。

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
