US1008FL_R1_00001 是强茂(PANJIT)推出的一款独立式快恢复高效率二极管,封装为 SOD-123FL。该器件额定直流整流电流为 1A,反向耐压高达 800V,适用于高压开关电源、离线适配器、LED 驱动、电机驱动等需要高压耐受与快恢复特性的应用场景。
该器件在 1A 工作点下 Vf 约为 1.7V,设计时应考虑功耗 P ≈ Vf×I,配合 PCB 散热与铜箔面积进行热降额。若应用中存在重复高浪涌,应确保 Ifsm 的非重复特性满足系统要求。Trr=100ns 属于快恢复级别,能有效降低开关损耗与电磁干扰,但在高速开关设计中仍需评估反向恢复电流对电路的影响。
SOD-123FL 为小型表面贴装封装,适配自动贴装与回流焊工艺。建议:
选择时参考实际电流、峰值浪涌与环境温度,必要时为降低结温采用更大铜面积或散热片。高压应用推荐在系统级进行泄放与滤波设计以控制瞬态电压。该器件工作结温最高 +150℃,但长期可靠性建议在安全边界内留有降额余量。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
