BAP64-05 产品概述

BAP64-05 是一款由 CJ(江苏长电/长晶)供应的通用小信号二极管,采用 SOT-23 小封装,内部为一对共阴极(common-cathode)二极管。器件针对空间受限、低功耗的便携与工业级电子电路设计,提供高达 175V 的反向耐压和良好的开关/整流性能,适用于各种保护、整流与电平处理场景。

一、主要规格

  • 二极管配置:1 对共阴极(双路二极管,公共阴极)
  • 正向压降(Vf):1.1 V @ 50 mA
  • 直流反向耐压(Vr):175 V
  • 最大整流电流(IF(AV)):100 mA
  • 反向电流(Ir):10 μA @ 175 V
  • 工作结温范围:-55 ℃ ~ +150 ℃
  • 封装:SOT-23(小体积、适合贴片工艺)
  • 品牌:CJ(江苏长电/长晶)
  • 产品型号:BAP64-05

二、产品特点

  • 高反向耐压:175 V 的电压等级,适合中高压信号或电源侧的反向保护与整流应用。
  • 低正向压降:在 50 mA 时 Vf 约 1.1 V,有利于减小开关损耗与热量产生。
  • 低反向泄漏:在最大反向电压下 Ir 仅约 10 μA,有助于高阻态下维持电路稳定。
  • 紧凑封装:SOT-23 体积小,便于在空间受限的 PCB 上布局,适合自动贴片与回流焊工艺。
  • 共阴极配置:方便构建二路输出共地或作钳位、比较器保护等电路布局,节省引脚资源。

三、典型应用场景

  • 小功率整流与电源保护(小型适配器、便携设备备用线路)
  • 输入反向保护、极性错误保护电路
  • 信号钳位、夹位保护(高压脉冲、浪涌抑制)
  • 电平移位与逻辑接口保护(在允许电压范围内)
  • 多路小电流开关与混合信号电路中的二极管矩阵

四、封装与引脚说明

  • 封装形式:SOT-23,常用三脚表面贴装封装
  • 引脚建议用途:两个阳极(或两个阴极,视封装引脚定义而定)与公共阴极的排列,便于并联或独立使用。详细引脚排列请参考器件数据手册与封装图纸。
  • PCB 布局建议:走线尽量短且粗,减少串扰;若长时间大电流工作,应在焊盘处增加铜箔厚度或热散区域以利散热。

五、使用建议与可靠性

  • 温度与功率热管理:虽然器件允许结温最高 +150 ℃,但 SOT-23 的散热能力有限,建议在连续工作时合理限制平均电流或采用合适的散热设计(增加 PCB 铜箔、拓展焊盘);对于脉冲场合,可承受短时较高电流。
  • 电流限制:标称整流电流为 100 mA,实际应用中应根据 PCB 散热条件和环境温度做降额设计以保证长期可靠性。
  • 焊接注意事项:适用于常规无铅回流工艺(请参照制造商数据手册中的回流曲线与湿敏等级信息)。
  • 工作环境:适合工业级温度;在高湿、高温、电化学迁移敏感应用中,需综合考虑封装防护与外壳设计。

六、典型电气参数(参考)

  • Vf = 1.1 V @ IF = 50 mA
  • Vr = 175 V(反向持续电压)
  • Ir ≤ 10 μA @ Vr = 175 V
  • IF(AV) = 100 mA(整流电流)
    (以上参数以制造商正式数据表为准,设计时请参考最新 Datasheet 的极限与典型曲线)

七、包装与采购建议

  • 包装形式通常为卷带(Reel)供 SMT 贴片线使用,请根据产线需求选择合适卷盘数量与单位包装。
  • 订购前建议确认制造批次、物料放行文件(如有)、以及产品的封装视图与引脚定义,以免因封装版本不同而产生装配问题。
  • 在关键应用场合,可要求样品做可靠性与温升测试,以验证在目标 PCB 和工作条件下的实际表现。

总结:BAP64-05 以其 175V 的耐压、较低的正向压降与共阴极双二极管结构,适合多种小功率整流与保护应用。合理的 PCB 热管理与电流降额设计能显著提升器件在实际工程中的可靠性与寿命。建议在最终设计前查阅并依据制造商完整数据手册中的详细参数与封装图进行验证。

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.
