US1M 是 BORN(伯恩半导体)推出的一款快恢复/高效率二极管,采用 SMA 封装(对应常见的 DO-214AC 贴片封装),面向高压整流与开关应用。器件在 1A 工作电流条件下正向压降约为 1.7V,直流反向耐压可达 1kV,反向漏电流在 1kV 时典型约 10µA,反向恢复时间 Trr 为 75ns,能承受非重复峰值浪涌电流 30A,工作结温范围为 -55℃ 至 +150℃(Tj)。
SMA(DO-214AC)封装便于自动化贴片与回流焊接,适合空间受限的功率模块。若应用要求更低的正向压降或更短的反向恢复时间,可考虑 Schottky 或超快恢复二极管家族;若电流等级或耐浪涌要求更高,应选用更大封装或并联设计。
总结:US1M 在 1A 级别的高压整流与中速开关场合提供了良好的耐压、恢复特性与封装便利性,是高压低至中功率电源与保护回路的实用选择。购买与设计前建议参考 BORN 官方数据手册获取完整的典型曲线与封装尺寸。

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.
