BAV103PF 产品概述

BAV103PF 是由 ST(先科)提供的一款无铅高压开关用二极管,单只独立封装,针对需要在高反向电压与中等工作电流条件下可靠整流与开关的应用而设计。器件具有较低的正向压降与极小的反向泄漏,配合良好的抗浪涌能力,适合在受限空间内实现高压脉冲或连续整流功能。

一、主要特性

  • 单只独立式二极管,封装型号:LL-34。
  • 无铅(RoHS 兼容),便于环保类产品设计与生产。
  • 正向压降 Vf ≈ 1.0 V @ IF = 100 mA(参考典型工作点)。
  • 直流反向耐压 Vr = 200 V,适合高压工作环境。
  • 最大整流电流(持续):250 mA,适用于中等电流整流场合。
  • 反向电流 Ir ≈ 100 nA(在额定条件下的典型泄漏水平)。
  • 非重复峰值浪涌电流 Ifsm = 3 A,可承受短时脉冲浪涌。

二、电气参数概览(关键项)

  • 正向压降(Vf):1 V @ 100 mA(用于评估功耗与温升)。
  • 直流反向耐压(Vr):200 V(评估最大反向工作电压与安全边际)。
  • 正向整流电流(IF):250 mA(持续使用时的额定电流)。
  • 反向漏电流(Ir):100 nA(典型值,实际随温度升高可能增加)。
  • 峰值浪涌电流(Ifsm):3 A(非重复脉冲,受脉冲持续时间与环境温度限制)。

(注:更详细的温度相关参数、动态恢复特性与典型曲线请参阅完整数据手册。)

三、封装与机械特性

  • 封装:LL-34,体积小巧,适合紧凑电路布局。
  • 单端引脚设计,便于安装与替换。
  • 无铅外形与封装材料,适合现代电子制造的环保要求。

四、典型应用场景

  • 高压开关与脉冲整流电路。
  • 保护电路:反接保护、浪涌抑制与钳位电路。
  • 高压小信号整流、检测与复位回路。
  • 电源模块中的局部整流与续流路径。
  • 需要低漏电和较高耐压的便携或工业控制设备。

五、设计与使用建议

  • 给予反向电压一定余量,避免长期在 Vr 近值处工作;在高温工况下反向泄漏会上升,应留有裕量。
  • 正向工作电流接近 250 mA 时,应考虑封装与 PCB 的散热能力,必要时采取外部散热或降额使用。
  • 浪涌电流 Ifsm 为非重复峰值脉冲能力,若应用存在频繁或较高能量浪涌,应选择更高浪涌能力的保护元件或并联限流措施。
  • 焊接与回流工艺应遵循无铅器件的标准工艺条件,避免超过元件的极限温度和应力。
  • PCB 布局时,确保高压回路走线留足间隙并采取适当的绝缘与爬电距离设计。

六、可靠性与采购建议

  • BAV103PF 属于通用高压开关型二极管,适用于批量生产与成熟电子系统。
  • 采购时请确认供应商的零件批次、器件来源及完整数据手册,以确保参数与封装一致。
  • 在关键应用中建议进行寿命与热循环评估,包括在目标温度范围内的漏电、正向压降和反向耐压测试。
  • 若需完全替代或比对产品,请以完整电气参数与封装图为准,优先选择同类额定 Vr、IF 与 Ifsm 的器件。

总结:BAV103PF 提供了在 200 V 级别下兼具低正向压降、低反向泄漏和中等整流能力的解决方案,适合高压开关与保护用途。在实际设计中应注意热管理、反向电压裕量与浪涌保护策略,以确保长期稳定运行。有关更详细的电气特性曲线和机械尺寸,请参考 ST(先科)提供的完整数据手册。

Sourcing availability signal

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
