US1D 是晶导微电子推出的一款独立式快恢复/高效率整流二极管,采用 SMA 封装,面向通用开关整流与电源管理应用。器件设计兼顾低正向压降与较短反向恢复时间,适用于降低整流损耗并提高开关效率的场景,具有良好的热稳定性与浪涌耐受能力。
以上参数为典型/额定值,具体使用时请参照晶导微电子提供的完整数据手册。
US1D 使用 SMA 封装,适配常见表贴生产工艺。建议在 PCB 布局时注意:
封装焊接请遵循晶导微电子的回流焊工艺和存储、搬运规范,避免过度热循环与潮湿引起的焊接缺陷。
当项目需要在 200 V 级别进行高效率整流且电流在 1 A 左右、同时希望降低开关损耗时,US1D 是性价比高的选择。若工作电流或频率显著高于此范围,可考虑更大电流或更短恢复时间的功率二极管或肖特基器件;若对反向耐压要求更高,则选择更高 Vr 额定的型号。
晶导微电子 US1D 提供了在通用整流与中高频开关场景下均衡的电气特性与可靠性,适合工业、电源与消费电子等多类产品设计应用。请在最终设计中参考厂商完整数据手册与典型应用电路以确保最佳性能。

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.
