1N5399 是鲁光(LGE)推出的一款独立式通用整流二极管,适用于中高电压整流与阻断场合。器件采用 DO-15 轴向封装,结构稳固、便于手工装配与波峰/回流焊接。该型号在高达 1kV 的反向电压下仍保持极低的反向漏流,正向压降在中大电流下表现平衡,适合线性电源、高压直流供电与保护电路等场景。
由此可见,1N5399 在高压工况下具有良好的阻断能力和低漏流特性;在 1.5 A 工作点时正向功耗约为 1.65 W(P = Vf × I),需注意散热管理。
DO-15 轴向封装体积小、热阻相对较高,器件的结温对寿命和参数影响较大。实务建议:
1N5399(LGE/鲁光,DO-15)是一款面向中高电压、低漏流需求的通用整流二极管,额定 1kV 反向耐压与 1.5A 连续整流能力使其在高压直流供电与保护电路中具有明显优势。选型时需兼顾散热、工作频率与浪涌要求,合理的热设计与测试验证可确保长期稳定可靠运行。若需替代或扩展应用,可根据电压、频率与功率要求选择相应的快恢复或肖特基器件。

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.
