US3M 产品概述 — BORN(伯恩半导体)

一、产品简介

US3M 是一款高电压、高可靠性的独立式整流二极管,封装为 DO-214AA (SMB)。该器件面向工业级电力电子应用,兼顾耐压、耐冲击和快速恢复特性,适用于开关电源、高压整流与电机驱动等场景。封装采用阻燃模塑料(UL 94 V-0),并符合 RoHS 无卤要求,可靠性与可制造性俱佳。

二、主要电气参数

  • 正向压降(Vf):1.7V @ If = 3A
  • 额定整流电流(Io):3A(连续)
  • 直流反向耐压(Vr):1000V(1kV)
  • 反向电流(Ir):典型 5 μA(常温)
  • 反向恢复时间(Trr):75 ns(典型)
  • 非重复峰值浪涌电流(Ifsm):200A(单次浪涌)
  • 工作结温范围:-55℃ 至 +150℃

三、封装与机械特性

  • 封装:DO-214AA (SMB),适配常见 SMT/通孔混合或插件安装布局
  • 端子:镀锡引线,焊接兼容性符合 J-STD-002 与 JESD22-B102 要求
  • 极性标识:阴极端以阴极线(带)标示,便于安装识别
  • 环保标准:符合 RoHS、无卤,模塑料满足 UL 94 V-0 阻燃等级

四、性能与应用优势

  • 高耐压(1kV)设计,适合高压整流与续流用途,如高压电源、充电器与光伏逆变器
  • 中等正向压降(1.7V @ 3A),在 3A 负载下保持良好效率与热耗控制
  • 快速反向恢复(75ns),在开关频率较高的电源中可降低开关损耗与电磁干扰
  • 优良的浪涌承受能力(200A)增强了对突发过电流的鲁棒性

五、典型应用

  • 开关电源(SMPS)整流与续流二极管
  • 工业电源与高压电源整流
  • 电机驱动、变频器中的保护与整流环节
  • 电池充电器、高压充电与电子镇流器
  • 任何需要 1kV 级整流或快速恢复功能的功率电路

六、装配与热管理建议

  • 建议在 PCB 上采用足够宽的铜箔与散热铺铜,必要时配合过孔下泄热以降低结温
  • 焊接按照 J-STD-002 和 JESD22-B102 的可焊性要求执行,避免过热造成封装应力
  • 使用过程中应留意连续高温环境,推荐保持结温在器件额定范围内以延长寿命

七、可靠性与合规

US3M 采用阻燃模塑材料与镀锡端子,满足工业级可靠性要求并符合 RoHS 无卤环保规范。产品适用于需要长期稳健运行的电力电子设备,提供稳定的电气性能与制造兼容性。

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
