DB207S 单相整流桥(JUXING 钜兴)产品概述

一、产品概述

DB207S 是钜兴(JUXING)出品的一款单相整流桥,采用 DBS 封装,适用于小功率至中等功率的整流场合。该桥整流器的典型正向压降为 1.1V(每只二极管在额定电流下的典型值),直流反向耐压达 1kV,最大整流电流 2A,非重复峰值浪涌电流 Ifsm 为 60A,反向漏电流 Ir 为 10μA,工作结温范围宽 (-55℃ 至 +150℃),在开关电源、适配器、仪表和工业控制等领域具有良好的适配性。

二、主要电气参数

  • 正向压降 (Vf):1.1V(典型,单个二极管在额定条件下)
  • 直流反向耐压 (Vr):1000V(1kV)
  • 直流整流电流:2A(平均整流电流)
  • 非重复峰值浪涌电流 (Ifsm):60A(脉冲性浪涌承受能力)
  • 反向电流 (Ir):10μA(在 Vr 条件下的典型漏电)
  • 工作结温范围:-55℃ ~ +150℃
  • 类型:单相桥式整流器
  • 封装:DBS(Molded Bridge)

三、产品特点

  • 高压耐受:1kV 的反向耐压适用于高压整流与隔离电路,增强系统安全裕度。
  • 低正向压降:每管约 1.1V 的压降有助于减少功率损耗与发热,提升效率。
  • 良好浪涌能力:60A 的峰值浪涌电流保证在通电启动、充电电容等场景下的短时抗冲击能力。
  • 宽温度工作范围:-55℃ 至 +150℃,适应恶劣环境与长期高温运行要求。
  • 低漏电流:10μA 的低反向电流适合高阻抗电路与低功耗应用。

四、封装与引脚说明

DBS 封装的 DB207S 为四端桥式封装,便于电路板直接安装。典型引脚功能如下:

  • ~(交流输入)- 两个相同标识的引脚,接交流电源或变压器次级。
  • +(正极输出)- 整流后正极输出。
  • -(负极输出)- 整流后负极输出(通常接地或回路负端)。 安装时请按封装丝印与电路图对应连接,注意引脚的机械强度与焊点完整性。

五、热设计与可靠性建议

  • 功耗估算:在额定整流电流下,桥内两个二极管轮流导通,整体压降导致的功率损耗约为 P ≈ Vf × Iavg × 占空(视负载波形而定),建议在 PCB 设计时预留足够铜箔面积和散热路径。
  • 散热处理:对于连续 2A 级别工作,建议在 PCB 下方加宽铜箔、增加热过孔或在金属壳体/散热片附近布局,以降低结温并延长寿命。
  • 环境与老化:在高温、高湿或含腐蚀性气氛中使用时,应考虑封装防护或选择更高等级的密封产品。

六、典型应用场景

  • 开关电源输入整流、次级回路整流
  • 充电器与适配器的整流模块
  • 工业控制与仪表电源
  • 家用电器小功率直流供电
  • 练功试验台、电子负载的整流单元

七、安装与焊接建议

  • 焊接工艺:遵循标准波峰焊或手工焊接工艺,避免过高温度和过长时间的局部加热以减少封装应力。若需回流,参照元件厂商或行业 IPC 指南的推荐温度曲线。
  • 机械应力:安装时避免拉扯引脚或在后续加工过程中对封装施加过大力,防止内焊线断裂或引脚松动。
  • PCB 布局:交流引脚和直流输出引脚间保持适当的爬电距离与绝缘措施,特别是在高压应用中遵循相应的安全间距标准。

八、选型与采购建议

选择 DB207S 时,请确认工作电压、整流电流与浪涌能力符合实际工况,若系统长期接近极限工作点,建议上级别型号或增加散热/保护方案(如限流电阻、熔断器、MOV、TVS 等)。采购时注明品牌(JUXING 钜兴)和封装 DBS,以确保一致性并便于替换。

九、常见注意事项

  • 反向耐压为 1kV,但在系统瞬态(雷击、开关浪涌)下应加保护器件以防超压击穿。
  • 若需要低正向压降以降低功耗,可考虑肖特基整流器,但其耐压与漏电流特性、温度范围需权衡。
  • 了解具体测试条件(如 Ir 测试电压与温度)有助于更准确地评估在目标应用下的表现。

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
