B245AF-13 产品概述
产品名称： B245AF-13
品牌： DIODES（美台）
类型： 肖特基二极管
封装： SMAF（DO-221AC）
一、基本特征
B245AF-13 是一种高性能的肖特基二极管，专为降低开关损耗和提高电能效率而设计。其反向电压最高可达45V，适用于多个电子应用场景。该二极管的正向电压在2A电流下为500mV，显示出优秀的导通性能。其平均整流电流为2A，能够满足多数中小功率设备的需求。
二、性能参数
反向电压（Vr）： B245AF-13 的最大反向电压达到45V，适用于需要中等电压的应用。这使得其可广泛应用于电源管理、直流变换器和其他要求反向电压不超过45V的场合。
整流电流（Io）： 该器件的平均整流电流为2A，满足了对中等电流承载能力的要求。其设计使得在较高电流条件下工作依然能够维持稳定性能。
正向电压（Vf）： 在额定电流2A下，正向电压仅为500mV，这一低压降特性为电子系统的能量效率增添了很大的优势，尤其是在电池供电和移动设备中的应用。
反向泄漏电流： 在最大反向电压45V时，反向泄漏电流为200µA，这样的指标有助于减少在静态条件下的能量损失，提高系统的整体性能。
电容： 在4V和1MHz的条件下，其电容为93pF，意味着该二极管在高频应用中能够保持稳定的性能表现，适用于快速开关电路。
速度： B245AF-13 是一种快速恢复二极管，其恢复时间小于500纳秒（ns）。这一特性使得它非常适合于高频率的开关电源和脉冲应用。
工作温度范围： 器件的结温范围为-55°C 至 150°C，允许其在极端环境条件下运行，使其适合于航空航天、汽车及工业应用等需要高可靠性和耐环境变化的场合。
三、应用领域
B245AF-13 的广泛应用使其成为电子设计中的理想选择。以下是一些主要应用领域：
- 电源管理： 适用于AC-DC转换器、DC-DC转换器、电池充电器等。
- 消费电子： 在智能手机、平板电脑和其他移动设备中，便于降低功耗与延长电池寿命。
- 工业控制： 作为保护二极管，确保设备在过电流或反向电压条件下的正常工作。
- 太阳能应用： 在逆变器和太阳能充电控制器中用于处理能量的整流与控制。
- 汽车电子： 用于汽车充电系统、LED驱动器等恶劣环境下的电子应用。
四、总结
B245AF-13 以其高效的电能管理、快速的开关性能和宽广的工作温度范围而著称，是电子设计中不可或缺的元素。它不仅能满足现代电子设备日益增长的性能需求，同时由于其低功耗特性，为应用系统提供了更高的能量效率。无论是在消费电子、工业控制，还是在电源管理中，B245AF-13 肖特基二极管都展示了其卓越的综合性能，是设计工程师在选型时值得信赖的选择。

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.
