B0505ST8-W3 产品概述

一、产品简介

B0505ST8-W3(品牌:YLPTEC/易川)是一款高集成度的隔离式DC-DC转换器,封装为TSOP-8。该器件在单颗芯片内实现输入到输出的电气隔离,适用于空间受限且需隔离供电的系统。其设计目标是在尺寸与可靠性之间取得平衡,免去额外隔离电源的布局与器件成本。

二、主要规格

  • 最大输出功率:300mW
  • 可选输出电压:3.3V、5V(输入5V时可获得3.3V或5V输出;输入3.3V时可获得3.3V输出)
  • 隔离耐压:5kV (典型)
  • 工作温度范围:-40℃ ~ +125℃
  • 封装:TSOP-8

三、关键特性

  • 单芯片集成隔离电源,省去外部隔离变压器或模块
  • 低功耗设计,适合便携或低功耗系统
  • 宽温度等级,满足工控、通信等严苛环境要求
  • 小尺寸TSOP-8封装,利于高密度PCB布局

四、典型应用场景

  • 工业控制信号隔离(模数/数模转换前端、电流/电压检测)
  • 通讯接口隔离(RS-232/RS-485、CAN等)
  • 隔离测量仪表与传感器供电
  • 安全与医疗类设备的次级隔离(需配合系统安全评估)

五、实用建议(布局与使用)

  • 在输入/输出端口靠近引脚放置去耦电容(例如0.1µF并联适当电解/钽电容),以保证瞬态响应与稳定性。
  • 保持输入侧与输出侧的爬电距离与飞弧距离,符合5kV隔离要求的PCB隔离走线规范。
  • 在高温环境下注意功率与效率衰减,给出适当的散热与热源隔离空间。

六、封装与可靠性

TSOP-8小型封装便于自动化贴装与回流焊接;建议按厂商焊接规范控制回流温度曲线,避免过热影响长期可靠性。长期工作于高温区间时,请参照厂商温度降额曲线评估使用寿命。

七、选型与订货提示

选型时请确认系统输入电压与所需输出电压版本(5V→5V/3.3V 或 3.3V→3.3V),并关注器件的隔离测试条件与认证要求。订货注明型号:B0505ST8-W3(YLPTEC/易川,TSOP-8)。

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
