S2M 通用高压整流二极管 — 产品概述
一、产品简介
S2M 是晶导微电子推出的一款独立式通用整流二极管，封装为 SMA (DO-214AC)。器件主要面向需高耐压、高整流电流及良好浪涌能力的电源整流和保护场景，典型工作结温范围为 -55℃ 至 +150℃。
二、主要电气参数
- 直流反向耐压 VR: 1000 V
- 直流整流电流 IF(AV): 2 A
- 正向压降 Vf: 1.1 V @ 2 A
- 非重复峰值浪涌电流 Ifsm: 50 A（按行业短时半波浪涌条件测得）
- 反向电流 Ir: 5 µA @ 1000 V
- 工作结温范围 Tj: -55℃ ~ +150℃
三、主要特点
- 高电压耐受：1000 V 反向耐压，适合高压整流与屏蔽保护用途。
- 低反向漏电：在满压下仅 5 µA，利于高压回路的静态稳定性。
- 良好浪涌承受力：50 A 的短时浪涌能力，可吸收瞬态冲击电流。
- SMA 封装，适合自动贴装与回流焊，封装耐热、可靠性高。
四、典型应用场景
- 开关电源二次整流、高压整流电路；
- 工业电源、仪器仪表高压部分；
- 逆变器、LED 驱动器以及需要高耐压保护的直流回路；
- 防反接保护、电荷泵与高压采样电路中的整流元件。
五、封装与热管理
SMA (DO-214AC) 封装在 PCB 布局时需考虑散热路径与焊盘面积。常规环境下 2 A 连续整流时产生的正向功耗约为 Vf×IF，可通过增加铜箔面积和热过孔减小结壳温升。高温运行或频繁浪涌时应进行适当降额设计。
六、使用建议与可靠性
- 在高压应用中注意 PCB 爆弧和爬电距离，确保间距满足安全规范；
- 对于突发浪涌，建议配合合适的限流/抑制元件（如保险丝、TVS）共同使用；
- 采用合适的回流焊工艺参数，避免超时超温，保证焊点可靠性。
- 器件符合常规工业环境可靠性要求，建议在极端环境下做样机验证。
七、订购与合规
型号：S2M，品牌：晶导微电子，封装：SMA (DO-214AC)。如需批量采购、样片或详细数据手册（含极限参数、封装图和焊接曲线），请联系晶导微电子销售或技术支持。该器件适用于符合 RoHS 要求的无铅装配流程。

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.
