B340-13-F 是一款高性能的肖特基二极管,广泛应用于各种电子电路中。其设计专注于低正向压降和高反向耐压,使其成为高效电源管理和整流应用的理想选择。以下是对该产品特点、规格、应用场景等方面的详细介绍。
1. 直流反向耐压(Vr)
B340-13-F 的最大直流反向耐压为40V。这意味着该二极管可以在高达40V的反向电压下正常工作,确保在电源设计中具备足够的安全裕度。
2. 平均整流电流(Io)
该二极管的平均整流电流为3A。在负载电流高达3A的情况下,B340-13-F 可以正常工作且保持稳定性能,适合大部分中等功率的整流应用。
3. 正向压降(Vf)
B340-13-F 在3A电流下的正向压降为500mV,表明其在工作时的功耗非常低。此外,低压降特性可以显著提高系统的整体效率,尤其是在电池供电及能源敏感的应用中。
1. 反向泄漏电流
在40V的反向电压下,反向泄漏电流仅为500µA,这一特性使其在高温及严格条件下也能保持优异的性能。较低的反向泄漏电流对于提升电磁兼容性和电路的稳定性至关重要。
2. 快速响应速度
B340-13-F 的恢复速度小于500ns,适合快速开关应用,如开关电源(SMPS)和高频率的功率转换器。同时,其速度特性允许用户在高速切换中确保电流的迅速导通与截止。
3. 容值特性
在4V条件下,B340-13-F 的结电容为200pF(在1MHz下测量),这一较小的电容值帮助减少交换损耗,提高电路响应速度,对高频应用尤为重要。
B340-13-F 采用SMD(表面贴装)型DO-214AB封装,具有良好的热管理性能,适合自动化的生产工艺流程。其物理体积小、安装简便,便于在密集的电路设计中使用。
B340-13-F 的应用领域非常广泛,主要包括:
B340-13-F 的工作结温范围为-55°C至125°C,这意味着其在恶劣环境及高温工作条件下依然能够保持稳定的性能。该产品的可靠性经过严格测试,适用于汽车电子、工业控制、消费电子等领域。
综合总结,B340-13-F 是一款性能卓越的肖特基二极管,以其低正向压降、适中的整流电流、优异的反向耐压和快速恢复速度等特点,成为电子工程师在设计电源管理和整流应用时的首选。标配的SMC封装使其兼具了良好的热性能与小巧的体积,是提升系统效率、保证电路稳定性的重要元件。无论是在高效电源、电子整流还是电池供电等领域,B340-13-F 都能提供可靠的解决方案。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
