产品概述：B140B-13-F 肖特基二极管
一、概述
B140B-13-F 是由 DIODES（美台）公司制造的一款高性能肖特基二极管，广泛应用于各种电子电路中，其关键参数使其特别适合电源管理、开关电源和其他需要快速整流的场合。该器件的主要特点包括较低的正向电压降和较高的反向耐压能力，使其在高效能和高可靠性方面表现出色。这款二极管采用表面贴装型SMB封装，帮助简化PCB设计，降低元件占用空间，满足现代高密度电子产品的需求。
二、关键参数
直流反向耐压（Vr）：B140B-13-F 的最大反向电压为40V，这一设计使其适合在大多数常见电源电压应用中运行，保证电路稳定。
平均整流电流（Io）：其额定平均整流电流为1A，适用于各种中小功率电路，确保在工作时能够稳定提供所需的电流输出。
正向压降（Vf）：该二极管在1A负载下的正向压降为500mV。这一低压降特性有助于最大限度地减少功耗，提高效率，尤其是在需要持续大电流的应用场景中。
反向泄漏电流：在40V的反向电压下，反向泄漏电流仅为500µA，这使得 B140B-13-F 在高温环境下仍能有效控制功耗，适合用于高温和高频应用。
反向恢复时间：该器件的速度达到快速恢复，响应时间小于500ns，对应电流大于200mA。这使得 B140B-13-F 非常适合在高动态范围和频繁开关的电路中使用，如开关电源和交直流转换器。
温度范围：B140B-13-F 可以在-65°C 到+150°C 的广泛温度范围内工作，展示了它在恶劣环境条件下的优秀稳定性和可靠性。
电容特性：在4V和1MHz频率下，电容值为110pF，这一特性有助于提高高频应用中的整体性能。
三、应用场景
B140B-13-F 肖特基二极管在许多场景中都可以找到其身影，以下列举了一些典型的应用：
电源管理：在开关电源和线性电源中，B140B-13-F 可以作为整流二极管，帮助将交流信号转换为直流电，同时保证良好的效率。
逆电流保护：在电池供电的设备中，B140B-13-F 可以用作逆电流保护器件，有效防止由于反向电流导致的电池损坏。
高频开关电源：由于其快速恢复特性，该二极管是高频开关电源的理想选择，能够减小开关损耗，提升电源转换效率。
RF应用：由于其低电容特性，B140B-13-F 可用于射频电路，降低信号损耗，保证信号传输的质量。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
