S2M 产品概述
一、产品简介
S2M 为 LGE（鲁光）出品的一款通用整流二极管，属于独立式封装器件，额定整流电流为 2A。器件适用于中高压整流与保护电路，具有较低的正向压降与良好的浪涌承受能力，适用于开关电源、适配器及工业电源场景。
二、主要电气参数
- 直流整流电流：2A（连续）
- 正向压降（Vf）：1.15V @ If=2A（典型）
- 直流反向耐压（Vr）：1000V（1kV）
- 反向电流（Ir）：5µA @ Vr=1kV
- 非重复峰值浪涌电流（Ifsm）：50A（单次脉冲）
- 工作结温范围：-55℃ ～ +150℃
三、封装与热性能
- 封装形式：SMB（DO-214AA）独立封装，便于手工焊接与自动化贴装。
- 热管理建议：虽为中等功率器件，但在持续 2A 工作下需考虑铜箔散热或散热岛设计，必要时靠近热源或使用散热片以降低结温并提高可靠性。
四、特点与优势
- 高耐压：1kV 额定可满足高压整流与保护需求。
- 低漏电：5µA @1kV 的低反向电流，有利于高阻荷载与高压回路的静态损耗控制。
- 良好浪涌承受能力：50A 峰值浪涌支持开机或短时脉冲冲击。
- 稳定正向压降：1.15V@2A 在常温下表现稳定，便于热设计与效率估算。
五、典型应用场景
- 开关电源（输出整流/续流）
- 适配器与充电器
- 工业电源与电机驱动的高压整流
- 电源保护（反向防护、续流二极管）
- 高压整流桥（与其他相同型号并联/串联使用需注意均流与耐压）
六、工程使用建议
- 在高温或连续满载环境下，对结温进行裕量设计，采用合适的铜箔面积与过孔散热。
- 若多只并联使用以提升电流能力，应保证器件温度一致以避免不均流。
- 对于高频开关场合，若对开关损耗或反向恢复时间有严格要求，请在样机验证中确认是否满足系统需求。
七、质量与采购
S2M 由 LGE（鲁光）制造，采用 SMB（DO-214AA）标准封装，适配常见 SMT/TH 换装方案。采购时请确认器件批次与完整的技术资料（datasheet）以便进行可靠性与环境试验验证。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
