30SQ045 产品概述

一、产品简介

30SQ045 是鲁光(LGE)出品的一款独立式肖特基整流二极管,封装为 R-6,适用于中大电流的整流和续流场合。该器件额定直流整流电流为 30A,直流反向耐压 Vr=45V,在 30A 条件下正向压降 Vf≈0.55V,非重复峰值浪涌电流 Ifsm=380A,工作结温范围宽(-55℃~+200℃),能够满足要求高温、抗冲击能力强的工业应用。

二、主要电气参数

  • 正向压降:Vf = 0.55V @ If = 30A(参考值)
  • 最大直流反向耐压:Vr = 45V(重复反向电压)
  • 直流整流电流:Io = 30A(连续)
  • 反向漏电流:Ir ≤ 500μA @ Vr = 45V
  • 非重复峰值浪涌电流:Ifsm = 380A(单次脉冲)
  • 工作结温:Tj = -55℃ ~ +200℃
  • 封装:独立式 R-6,便于散热与安装

以上参数为典型/额定值;具体工作条件下的热行为和寿命请参考厂方数据手册并按实际工况修正。

三、特点和优势

  • 低正向压降:0.55V 的 Vf 在 30A 等级中属于较低水平,有助于降低整流损耗,提高整机效率。
  • 高浪涌承受力:380A 的峰值浪涌能力适合启动电流大或短时过载的场合。
  • 宽温工作范围:最高结温可达 200℃,适合高温环境或对散热空间有限的设计。
  • 结构独立、封装便于安装:R-6 独立式封装方便与散热体直接固定,提高热交换效率。

四、典型应用场景

  • 开关电源整流输出、整流桥(单只或并联使用)
  • DC-DC 降压转换器的续流/钳位二极管
  • 汽车电子(12V/24V 系统的整流和保护)与工业电源(48V 以下)
  • 电机驱动、逆变器辅助整流、电池保护/反向保护电路

五、选型与使用建议

  • 在长期连续工作时,应考虑器件结温升高引起的 Vf 上升与漏电流增加,必要时进行电流降额或加强散热(加散热片、强制风冷)。
  • 对于对静态漏电流敏感的低功耗电路,30SQ045 的 Ir(500μA@45V)可能较高,应考虑选用低漏型肖特基或使用并联低电阻设计分担漏流影响。
  • 若系统可能出现频繁高幅度浪涌,检查 Ifsm 与实际浪涌能量匹配,或采用并联/并联+限流保护方案提高可靠性。
  • 安装时保证夹紧面和散热面良好接触,避免过度机械应力损伤封装。

六、可靠性与注意事项

  • 请按照厂方的焊接和热循环规范进行安装,避免超温焊接或长期超额结温工作。
  • 在高湿度或腐蚀环境中,应采取防护措施(涂层或封装防护)。
  • 出货与贮存时注意防静电、防潮,避免机械冲击导致封装破损。

总结:30SQ045(LGE,R-6)是一款面向中大电流、低压降、高温环境的肖特基整流二极管,适合在工业电源、车载供电和功率变换系统中作整流或续流之用。选型时应综合考虑 Vf、Ir、Ifsm 与系统散热能力,确保在规定结温范围内长期稳定运行。若需更详细的封装机械图、热阻或完整电气特性曲线,请参阅厂方数据手册或联系供应商技术支持。

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
