US1MG 是时科(SHIKUES)推出的一款独立式快恢复二极管,采用 SMA(DO-214AC)封装,面向高压整流与中高速开关电路。器件在保持较低正向压降的同时提供 1kV 的反向耐压能力和较快的反向恢复特性,适合需要高效率和耐冲击能力的功率应用场合。
这些参数使 US1MG 在高压整流、开关电源回路及浪涌保护中有良好表现,兼顾功率损耗与瞬态承受能力。
SMA(DO-214AC)封装体积小、适合表面贴装工艺。尽管器件额定连续电流为 1A,但由于封装体积和热阻限制,实际 PCB 设计时需重视散热:
US1MG(SHIKUES)是一款面向高压整流与中速开关场合的快恢复二极管,1000V 的耐压、1.65V 的正向压降与 75ns 的反向恢复时间在性能与成本之间取得平衡。适用于开关电源、LED 驱动、高压整流与浪涌保护等应用。选型时应关注开关频率、热管理与系统浪涌特性,合理设计 PCB 散热与保护电路,以发挥该器件的稳定性与可靠性。

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.
