SS315A（DOWO）产品概述
一、简介
SS315A 是 DOWO（东沃）推出的一款单只独立整流二极管，SMA 封装，适合自动贴装生产。该器件设计用于中等电流整流与过压保护场合，具有低正向压降、低反向泄漏和宽工作结温范围，满足工业级应用对可靠性与寿命的要求。
二、主要电气参数
- 正向压降 (Vf)：约 850 mV @ If = 3 A（低损耗，适合高效率设计）
- 直流反向耐压 (Vr)：200 V
- 额定整流电流：3 A（持续工作）
- 反向电流 (Ir)：≤100 μA @ Vr = 200 V（漏电小，适合高阻抗电路）
- 非重复峰值浪涌电流 (Ifsm)：70 A（单次冲击能力强）
- 工作结温范围：-55 ℃ 至 +175 ℃（适应宽温环境）
三、产品特性
- 封装紧凑（SMA），体积小、散热性能稳定，利于自动贴片和高速装配线。
- 低正向压降，减小导通损耗，提高系统效率并降低热量产生。
- 具保护环结构（guard ring），改善击穿特性，提高耐压与抗浪涌能力。
- 符合 RoHS 无卤标准，满足环保与法规要求。
- 高正向浪涌承受力，适合有启动突波或短时过载的场合。
四、典型应用场景
- 开关电源（SMPS）整流、输出回路保护。
- 适配器与充电器的整流与反接保护。
- LED 驱动、电机驱动与工业控制电源。
- 通信设备、家电和消费电子中需要 200 V 级耐压与 3 A 整流能力的场合。
五、封装与可靠性建议
- SMA 封装利于回流焊工艺，推荐遵循制造商的回流温度曲线以确保焊接可靠性。
- 虽然工作结温上限为 +175 ℃，但为延长寿命应尽量降低结温，合理设计散热路径和铜箔面积。
- 在有频繁大浪涌的应用中，应评估 Ifsm 要求并视情况增加限流或软启动措施。
六、选型与采购提示
产品型号标识为 SS315A（DOWO），请选择正规渠道采购以保证原厂元件及合格的 RoHS 证书。为获得更详细的电特性曲线、封装尺寸与焊接资料，请参考 DOWO 官方规格书或联系供应商获取样片和测试报告。
综上，SS315A 以其低 Vf、较高 Vr 和良好的浪涌能力，适用于追求效率与可靠性的中等功率整流与电路保护应用。

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.
