SS520 是江苏长电(CJ/长晶)生产的一款肖特基整流二极管,面向中等功率直流整流和开关电源应用。该器件以低正向压降和快速恢复特性为主要优势,适合在高开关频率和高效率要求的电源电路中作为整流、续流或反向极性保护器件使用。其基本电气和热性能指标如下:直流反向耐压 Vr = 200 V;额定平均整流电流 IO = 5 A;反向电流 Ir = 200 μA(在 Vr = 200 V 时);非重复峰值浪涌电流 Ifsm = 150 A;工作结温范围 Tj = -55 ℃ ~ +150 ℃;封装为 SMAG。
如需进一步的电气特性曲线(Vf–If、Ir–Vr、功耗–温度、热阻 RθJA/RθJC)、封装尺寸图或具体 PCB 焊盘设计建议,我可以根据厂方 Datasheet 帮您提取并给出针对性的布局与热管理方案。

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.
