US1M 是一款独立式快恢复整流二极管,适用于需要较高耐压与快恢复特性的整流或自由轮回回路。品牌:TWGMC(台湾迪嘉),封装为SMA,工作结温范围宽(-55℃ ~ +150℃),单只整流电流1A,兼顾体积与热性能,适合中等功率密度应用。
注:给定信息中存在反向耐压(Vr)值的描述差异(基础参数列出100V,而描述处提到1kV)。本文为便于工程选型,以型号US1M常见含义和描述中的“1kV”作为参考耐压(1000V)进行说明;若实际器件为100V等级,请以实际出货数据表为准。
US1M(SMA封装)为一款面向高压整流与快恢复需求的实用二极管,兼顾较高耐压、快回复时间与适中正向压降,适合SMPS 输出、逆变或高压整流场合。选型时请以厂家最终数据表为准,结合系统电压、浪涌能力与散热条件进行热、电综合评估,以确保长期稳定可靠运行。若需要,我可根据你的系统电压、工作频率与PCB散热条件,帮助做更具体的选型与热设计建议。

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.
