US1D_R1_00101 是 PANJIT(强茂)推出的一款独立式快恢复高效率整流二极管,采用 SMA 封装。该器件专为开关电源和高频整流场合设计,兼顾低正向压降与较快的恢复特性,能够在中等频率电源转换与浪涌抑制场景中提供可靠的整流与保护功能。
以上参数适用于典型测试条件,实际应用中请参考厂商完整数据手册并考虑 PCB 散热与环境温度对性能的影响。
SMA 封装体积小、适合集成密集电路板,但受限于热阻和散热面积。尽管器件额定为 1 A 连续整流,实际持续电流能力受 PCB 铜箔面积和工作温度影响。建议在高负载或高环境温度应用中通过加大铜箔厚度/面积或增加散热结构来改善热管理。
PANJIT 品牌提供的 US1D_R1_00101 适合追求成本与性能平衡的中低功率整流应用。如需替代件,请匹配关键参数:Vr ≥ 200 V、IF ≥ 1 A、Vf 接近 1.3 V、Trr 接近或优于 50 ns,并保持 SMA 或兼容封装以便于 PCB 布局替换。详情与样品或批量采购建议联系官方渠道或授权分销商,并参考最新数据手册以获取完整电气与机械规格。

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.
