B140AF-13 是一款由美台（DIODES）生产的肖特基二极管，其主要设计用于功率管理、整流电路以及其他需要快速开关的电子应用。该二极管以其优越的电气性能且适合表面贴装（SMD）技术，能够满足现代电子设备小型化和高效能的需求。

二、基本参数

  1. 二极管类型: 肖特基
  2. 反向电压（Vr）最大值: 40V
  3. 平均整流电流（Io）: 1A
  4. 正向电压（Vf）: 500mV @ 1A
  5. 反向泄漏电流: 200µA @ 40V
  6. 工作温度范围: -55°C ~ 150°C
  7. 电容（C）: 50pF @ 4V, 1MHz
  8. 封装类型: SMAF (DO-214AD)

三、性能特点

  1. 低正向压降: B140AF-13 的正向电压为 500mV @ 1A，这使得在整流时有更高的效率，减少了功耗，尤其适合需要高效率的电源转换应用。

  2. 快速恢复特性: 这款二极管具有快速恢复特性，其恢复时间小于或等于 500ns，适合高频大电流开关应用，比如开关电源和高频逆变器。

  3. 低反向泄漏电流: 在最高额定反向电压 40V 下，仅有 200µA 的反向泄漏电流，有助于提升电路的整体效率和稳定性。

  4. 宽工作温度范围: 可在 -55°C 到 150°C 的温度范围内正常工作，使其适用于各种严酷环境的电子产品，包括汽车电子、工业控制等。

四、封装与安装

B140AF-13 采用 SMAF 封装（封装编号 DO-214AD），该表面贴装型设计能够有效节省空间，适合现代电子产品的紧凑设计。其小型化的特点也带来了良好的散热性能，为电路提供可靠的保护。

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
