BAT760-7 产品概述

一、产品简介

BAT760-7(品牌:DOWO / 东沃)是一款小型封装的整流/保护二极管,采用SOD-323封装,适用于对体积、成本和开关速度有要求的消费电子与工业控制场景。该器件在小型表面贴装封装中实现了可观的整流性能和浪涌承受能力,适合用作反向保护、整流和钳位等应用。

二、主要电气参数

  • 正向压降 Vf:0.875 V @ If = 3.0 A
  • 额定整流电流:1 A(持续正向电流)
  • 非重复峰值浪涌电流 Ifsm:9 A(单次脉冲)
  • 直流反向耐压 Vr:30 V
  • 反向电流 Ir:1 mA @ Vr = 30 V
  • 封装:SOD-323(小型表面贴装)

这些参数表明该器件在中等电流、低电压系统中具有较好的脉冲承受能力,但在持续大电流场合受限于封装热阻与额定整流电流。

三、特性与优势

  • 小型化封装(SOD-323),利于高密度 PCB 布局与节省空间。
  • 具有一定的抗浪涌能力(Ifsm 9A),能承受启动或短时电流冲击。
  • 低至中等的正向压下降(0.875 V @ 3 A),在功率与效率之间取得平衡。
  • 反向耐压 30 V,适合常见的5V、12V系统保护应用。

注:反向漏电流在最大反向电压下可达 1 mA,需在低漏电流要求的应用中评估可接受性。

四、典型应用场景

  • 电源线路的整流与反向极性保护(如便携设备、消费电子)。
  • 输入电源的浪涌钳位与抑制。
  • 二极管耦合或隔离用途(例如电源切换/OR-ing),在电流需求不超过器件额定值时使用。
  • 小电流电源和信号通路的快速保护元件(需注意反向漏电流对电路的影响)。

五、设计与布板建议

  • SOD-323 为小型表贴封装,热阻相对较高。若工作于接近额定电流或有频繁脉冲,建议增加焊盘铜面积以利散热;必要时将焊盘接到较大散热层或铜箔。
  • 对于持续或高频脉冲应用,推荐在评估真实工况下测量结温(Tj),并确保不超过器件允许的温度范围。
  • 布线时应缩短与二极管相关的导线长度,减小寄生电感和串联阻抗,以提高浪涌承受性能。
  • 如果用于逆向阻断或静态保护,应考虑反向漏电流对系统待机功耗和信号完整性的影响。

六、可靠性与使用注意

  • SOD-323 封装适合自动化贴装,但在回流焊、手工焊接时须注意温度曲线以免焊接损伤器件。
  • 该器件能承受短时峰值浪涌,但反复超过额定脉冲可能降低寿命,应在系统设计中留有余量。
  • 反向漏电流为 1 mA(30 V),在对漏电流敏感的低功耗或计量电路中需谨慎选型或并联低漏电器件以满足要求。
  • 推荐在样品评估阶段做整流效率、结温和寿命测试,验证在目标环境下的稳定性。

七、封装与订购信息

  • 封装:SOD-323(小型外形,适合高密度贴装)
  • 品牌:DOWO(东沃)
  • 型号:BAT760-7
  • 订购与样片申请时请确认完整的器件标识、包装形式(卷带、托盘)与出货单位,以便于 SMT 生产与库存管理。

总结:BAT760-7 是一款体积小、抗浪涌能力可观且适用于低电压整流与保护的表贴二极管。设计时需关注封装带来的散热限制与反向漏电流特性,在合适的工作点上可为各类便携与工业电子设备提供可靠的保护与整流功能。

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.
