B340A-13 为 GOODWORK(固得沃克)出品的独立式肖特基整流二极管,封装为 SMA (DO-214AC),面向需要低正向压降与高速整流的电源和保护电路。此型号在直流整流电流 3A 的工况下,典型正向压降仅 0.50V,适合降额设计或要求高效率的小功率开关电源与续流路径。
SMA 封装体积小,便于自动贴装与波峰/回流焊接,但散热依赖 PCB 版图与铜箔面积。建议:
B340A-13 适用于要求低 Vf、3A 连续整流和 40V 耐压的场景。若需更高耐压或更低漏电,可考虑其它肖特基或快速恢复二极管;若需更高电流等级,则选择更大封装(如 DO-214AA/DO-214AB)或并联使用并做好热均流设计。订购时请确认 GOODWORK 的完整型号、批次与质量认证,以确保可靠性与可追溯性。
如需封装尺寸图、热阻参数或典型电气特性曲线(Vf‑If、Ir‑Vr‑T),可基于具体应用索要 GOODWORK 的详细 datasheet,以便进行精确的热设计与电气仿真。

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.
