1N5819 是一款通用肖特基(Schottky)整流二极管,扬杰(YANGJIE)提供的该型号采用 DO‑41 轴向穿孔封装,面向整流、保护与开关电源等应用。其主要特点是正向压降较低、回复速度快、抗浪涌能力良好,适合中等电流的电源与保护电路。
主要标称参数(按提供数据):
DO‑41 为轴向引线的穿孔封装,易于手工焊接与波峰/选择性焊接安装,适合中小批量或维修场景。封装尺寸允许在 PCB 或面包板上灵活布局。引脚极性通常在器件一端有标记(注:装配时注意确认阳极/阴极方向)。
工作结温范围 -55 ℃ ~ +125 ℃ 适用于工业级应用。肖特基结构对高温更为敏感,长期高温会影响反向漏电与可靠性。对潮湿与温度循环的应力测试应参考扬杰供货的完整可靠性报告(如 HTRB、温度循环、湿热等)。
总结:扬杰 1N5819(DO‑41)是一款面向中等电流、40 V 级别的通用肖特基整流器,低正向压降和较好的浪涌能力使其在电源整流、反接保护和续流等场景中具有良好性价比。选型时请结合实际工作温度、漏电容忍度与散热条件,并参照厂方完整 datasheet 以获得全部测试条件和限制说明。

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.
