B340AXF-13 是 DIODES(美台)推出的一款功率肖特基整流二极管,采用 DO-214AD 表面贴装封装,面向中低压高电流整流与保护应用。器件以低正向压降、快速开关、良好的浪涌承受能力和宽工作温度范围为主要特点,适用于开关电源输出整流、二极管 OR-ing、反向极性保护以及瞬态抑制等场合。
DO-214AD(SMB 类型)为常见的功率肖特基表面贴装封装,适合自动化 SMT 贴装与后续波峰或回流焊接。封装便于 PCB 散热设计,但在高功耗场合仍建议配合较大铜箔和热沉方案。出货时请按厂家条形码 / 批次管理,确保在适宜的干燥与温度条件下储存,避免长期潮湿影响焊接性。
B340AXF-13 以 0.5 V 左右的低正向压降与 3 A 连续整流能力为主要卖点,适合低压高流、高频开关电源输出整流、反向保护与电源 OR-ing 等应用。设计时重视 PCB 散热、漏电流随温度变化与浪涌限制,遵循制造商的焊接与可靠性建议,能在功率密集和空间受限的系统中提供高效可靠的整流与保护功能。
如需精确的热阻、完整电气特性曲线、封装机械尺寸或推荐回流曲线,请参照 DIODES 官方数据手册或联系厂商技术支持获取原厂资料。

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.
