RSX068MP2STR 产品概述

一、产品简介

ROHM(罗姆)RSX068MP2STR 是一款面向中高压整流与开关电源应用的单向二极管,隶属于 PMDU 系列,特色为超低反向电流(Ultra low IR)与紧凑低高度封装。器件封装为 SOD-123FL,适合空间受限且要求良好散热的表面贴装方案。典型电气参数满足工业与消费类电源对效率与待机漏电的双重要求。

二、主要参数(典型值)

  • 正向压降 (Vf):0.890 V @ IF = 2 A
  • 额定整流电流 (IF):2 A(连续)
  • 直流反向耐压 (VR):200 V
  • 反向电流 (IR):100 nA @ VR = 200 V
  • 非重复峰值浪涌电流 (Ifsm):50 A
  • 封装:SOD-123FL
  • 单个(Single),PMDU 系列,Ultra low IR

三、主要特点与优势

  • 超低反向电流(100 nA@200 V):显著降低待机功耗,适用于节能型适配器与待机严格的家电/消费电子。
  • 低正向压降(≈0.89 V @ 2 A):减小导通损耗,提高整机效率,尤其在整流与输出二次侧应用中效果明显。
  • 高耐压(200 V):可直接应用于离线开关电源与高压整流场景。
  • 良好浪涌承受能力(50 A Ifsm):支持启动或短时浪涌电流,提升可靠性。
  • SOD-123FL 封装:体积小、厚度低、焊接强度与热散能力均优于传统小体积封装,便于自动贴装。

四、典型应用场景

  • 开关电源(SMPS)整流与输出整流
  • 离线适配器、电源模块的续流/整流二极管
  • LED 驱动电源与照明控制器
  • 家电控制板与工业电源,需兼顾高压与低漏电的场合

五、使用与布局建议

  • 热管理:在高电流连续工作时,器件功耗约为 Pd ≈ Vf × IF(例如 0.89 V × 2 A ≈ 1.78 W),建议在 PCB 采用较大铜箔散热区(下方与附近铺铜、过孔导热),并尽量缩短走线以降低寄生电阻。
  • 布局:靠近整流点放置,走短粗铜线,避免长窄走线导致额外发热。封装焊盘按厂商推荐尺寸设计以保证可靠焊接与热传导。
  • 滤波与保护:在可能出现反向浪涌或高 dv/dt 场合,配合合适的 RC 抑制或 TVS 器件使用,以提高系统鲁棒性。
  • 焊接工艺:遵循回流曲线与再流温度限制,避免过高温度或多次回流造成性能下降。

六、可靠性与选型提示

  • Ifsm 为非重复峰值浪涌电流,表示短时间浪涌承受能力,长期冲击或重复浪涌需额外评估与保护。
  • 若设计对正向压降有更严格要求,可考虑低 Vf 型或肖特基二极管;若需要更高耐压,则选择更高 VR 的型号。
  • 建议在样片阶段进行温升与寿命验证,关注结温(Tj)在最大额定范围内的变化对 Vf 与 IR 的影响。

RSX068MP2STR 凭借低漏电、低压降与紧凑封装,适合对能效与空间有双重要求的中高压整流应用。购买与详细封装尺寸、回流规范请参见 ROHM 官方资料或向授权分销商咨询。

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
