LDSR01S30ST5G 产品概述

一、简介

LDSR01S30ST5G 是乐山无线电(LRC)推出的一款肖特基二极管,采用 DFN0603 小封装,面向便携式和高密度电路板的低压整流与防反接应用。器件以低正向压降和低反向漏电为主要卖点,适合在空间受限且需降低导通损耗的场景使用。

二、主要参数

  • 正向压降 (Vf):约 620 mV
  • 直流反向耐压 (Vr):30 V
  • 整流电流 (Io):100 mA(额定整流电流)
  • 反向电流 (Ir):350 nA(常温标称)
  • 非重复峰值浪涌电流 (Ifsm):2 A(单次、非重复浪涌)
  • 封装:DFN0603(小尺寸表贴)

三、优点与特性

  • 低正向压降:降低导通损耗与发热,有利于提升系统效率,尤其在低压大电流场合更明显。
  • 低反向漏电:350 nA 的低漏电有助于电池供电与待机电流要求较严的设计。
  • 小尺寸封装:DFN0603 便于高密度布局,节省 PCB 面积。
  • 良好的浪涌能力:2 A 单次浪涌容忍短时冲击,适用于上电冲击场景。

四、典型应用

  • 低压整流与二极管隔离(电源输入、充电器)
  • 反向保护(电池和外部电源接入)
  • DC-DC 转换器的输出整流或钳位元件
  • 便携设备、工控板、通信模块等空间受限的系统

五、封装与焊接建议

DFN0603 封装导热面积有限,建议在 PCB 设计时优化焊盘和散热过孔布局以提升热耗散能力。采用常规无铅回流焊工艺,注意控制回流曲线以避免过热引起性能退化。采用良好焊盘定义(solder mask defined / paste stencil)可提高coplanarity和焊接一致性。

六、选型建议与注意事项

  • 若工作电流接近额定 100 mA 或长期高温环境,应适当降额使用并评估封装热阻。
  • 反向漏电随温度上升显著增加,如待机和高温工况对漏电敏感,应在实际温度下核验 Ir。
  • 若需要更高耐压或更大持续电流,请选用更大封装或更高 Vr/Io 规格的肖特基器件。
  • 浪涌能力为单次峰值,若需重复浪涌或冲击频繁,应选用更高 Ifsm 的型号或添加限流保护。

LDSR01S30ST5G 在追求小体积、低损耗和低待机电流的低压电源设计中具有很好的性价比,是便携与嵌入式电源保护与整流的常用选择。

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
