BAP64-03 产品概述

一、产品简介

BAP64-03 是时科(SHIKUES)推出的一款独立式小信号整流二极管,采用 SOD-323 封装,面向对体积、耐压和反向漏电有要求的便携及通信类电路。该器件在典型工况下具有良好的正向导通特性与较低的反向漏电,适用于小电流整流、开关整流和防反接保护等场合。

二、主要电气参数

  • 二极管配置:独立式
  • 正向压降(Vf):0.95 V @ IF = 50 mA
  • 直流反向耐压(Vr):175 V
  • 最大整流电流(Io):100 mA(连续)
  • 反向电流(Ir):≤10 μA @ Vr = 175 V
  • 工作结温范围:-65 ℃ ~ +150 ℃
  • 封装:SOD-323(小体积表面贴装)

以上参数基于常规测试条件,Vf 特性在 50 mA 时为典型参考值,实际应用中温度和脉冲条件会影响即时数值。

三、关键特性与优势

  1. 高耐压:175 V 的反向耐压使得 BAP64-03 可用于较高电压环境下的小电流整流或保护电路,适合隔离电源、开关电源的次级回路或高压信号通道。
  2. 低反向漏电:在最大反向电压下反向电流仅 10 μA,便于在高阻抗测量、低功耗电路中保持小泄漏,避免对敏感节点造成干扰。
  3. 稳定的正向压降:0.95 V @ 50 mA 的 Vf 值在小信号整流中提供可预见的压降,有利于电路的稳态设计与功耗估算。
  4. 宽温度范围:-65 ℃ 至 +150 ℃ 的工作结温适应恶劣环境与工业级应用,保证在高温场合下的可靠性。
  5. 小型封装:SOD-323 体积小、适合高密度贴片组装,利于便携设备和密集板级设计。

四、典型应用场景

  • 小电流整流与开关整流:适用于逻辑电源、次级整流或小功率电源模块。
  • 反向极性保护:在电源输入端或子系统中防止误接导致损坏。
  • 高压信号钳位与保护:用于抑制短时过压或作为隔离通道的保护元件。
  • 通信设备与测量仪表:在对漏电流敏感的输入通道与高阻抗测量电路中使用。
  • 便携与消费电子:在尺寸受限的 PCB 布局中实现可靠的整流与保护功能。

五、封装与可靠性注意事项

BAP64-03 的 SOD-323 封装便于自动贴装与回流焊工艺,建议参考以下封装与工艺建议以保证良好可靠性:

  • 回流焊温度曲线应符合通用无铅工艺规范,避免超过器件最大结温限制。
  • 焊盘设计应兼顾热量分布与足够的焊接面积,减少焊接应力集中以保证机械可靠性。
  • 在高湿或苛刻环境下建议进行适当的防潮处理与保管;长期存储请按 J-STD-033 等规范控温防潮。
  • 过流或短路保护应在电路设计中考虑,尽量避免长期在接近或超过规格最大额定值(100 mA)下工作。

六、使用与设计建议

  • 在需要更低正向压降或更大整流电流的场合,考虑与 Schottky 或更大电流等级的器件对比选择。
  • 设计时对 Vf 和 Ir 做温度与工作点的余量评估,尤其在高温工况下正向压降和漏电可能变化明显。
  • 若用于开关场合,关注器件的恢复特性与在高频脉冲下的性能;必要时进行实际测量验证。
  • PCB 布局中将敏感节点与高压节点隔离,留出适当爬电距离,保证安全与抗干扰能力。

七、结论

BAP64-03(SHIKUES 时科,SOD-323)是一款面向小信号整流与高压低电流保护应用的元件,结合 175 V 耐压、低反向漏电和宽温度范围特性,在通信、仪表、便携与工业类设备中具有良好的实用性与可靠性。按推荐的封装与焊接工艺使用,并在电流与温度设计上留有余量,可获得稳定长期的工作表现。若需更详细的电气特性曲线或封装尺寸图,请参考厂方数据手册以便完成最终设计验证。

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.
