  • 高反向耐压:该二极管的直流反向耐压(Vr)达到了40V,能够在相对较高的工作电压环境中正常运行,适合多种应用场合。
  • 极低的反向泄漏电流:在40V时,反向泄漏电流仅为12µA,表明该元件在关闭状态下几乎不浪费电能,符合现代节能设计的要求。
  • 快速恢复特性:STPS140U的恢复时间小于500ns,在高频开关应用中表现出良好的性能,有助于提高开关电源的效率,减少电磁干扰。
  • 广泛的工作温度范围:结温最高可达150°C,意味着该组件可以在严苛的环境条件下稳定工作,适应多种工业应用。

2. 封装和安装类型

STPS140U采用表面贴装型(SMD)封装,符合DO-214AA (SMB)国际标准。这种封装形式使得该二极管在PCB版上的布局设计更为紧凑,适合现代小型化电子产品的需求,同时也便于自动化焊接,对于大批量生产具有明显优势。

3. 应用领域

STPS140U广泛应用于各类电子电路中,尤其是在以下领域具有显著的优势:

  • 开关电源:由于其较低的正向压降和快速恢复特性,使其非常适合在开关电源中作为整流二极管使用,能够有效提升开关电源的转换效率。
  • 电池充电器:其低反向泄漏电流特性使其能够显著延长电池充电器的使用寿命,同时提高充电效率。
  • 逆变器:在逆变电路中,STPS140U的高反向耐压特性确保了其能在高压环境中稳定运行,同时避免能量损失。
  • LED驱动电路:在LED照明设计中,STPS140U可用于整流电路,为LED提供稳定的直流电源,确保其亮度和使用寿命。

4. 技术参数总结

以下是STPS140U的关键技术参数列表:

  • 二极管类型:肖特基
  • 直流反向耐压(Vr):40V
  • 平均整流电流(Io):1A
  • 正向压降(Vf):550mV @ 1A

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
