SS14（DOWO 东沃）肖特基二极管 产品概述
一、产品简介
SS14 是一款独立式肖特基整流二极管，封装为 DO-214AC（SMA），由 DOWO（东沃）提供。该器件以低正向压降和快速开关特性为主要卖点，适合中低电压、1A 等级的整流与保护场景。器件规格中的核心参数包括：正向压降 Vf = 550 mV（在 1 A 条件下）、直流反向耐压 Vr = 40 V、额定整流电流 1 A、反向电流 Ir = 100 μA（在 40 V）以及非重复峰值浪涌电流 Ifsm = 30 A。工作结温范围为 -55 ℃ 至 +150 ℃。
二、电气性能要点
- 正向压降：550 mV @ 1 A，具有明显的能量损耗降低优势（相比普通整流二极管）。
- 反向耐压：40 V，适用于常见低压供电系统。
- 反向泄漏：100 μA @ 40 V，需在高温或高阻断电压时关注漏电上升。
- 浪涌能力：30 A（峰值、非重复），能承受瞬态冲击电流。
- 额定电流：1 A（连续整流），在高温或散热不足时需降额使用。
三、结构与封装优势
DO-214AC（SMA）封装在机械强度与散热之间取得平衡，适合表面贴装工艺（SMT）或手工焊接。独立式（离散）元件便于在电源输入、二次整流或保护回路中单独替换与调试。
四、典型应用场景
- 开关电源（输入整流、续流二极管）
- 功率管理与降压转换器的肖特基整流
- 反向极性保护与二极管 OR’ing
- 热插拔、USB 供电保护及快速恢复整流
- 工业与消费电子低电压电源路径
五、设计与使用建议
- 散热设计：1 A 连续工作时须保证良好散热，PCB 加大铜箔或设置热过孔以降低结温。
- 温度影响：反向泄漏随温度上升显著增加，高温环境下需适当降额或选用更高 Vr/更低 Ir 器件。
- 浪涌保护：虽具 30 A 峰值能力，但频繁冲击会缩短寿命，关键场合建议配合限流或浪涌抑制元件。
- 并联注意：若需提高电流能力，应注意器件 Vf 的匹配与均流，否则并联效果有限。
六、可靠性与采购提示
工作结温范围宽（-55 ℃ 至 +150 ℃），适应工业级应用。选择时确认来源渠道与批次质量，查看供应商的质量保证（如 RoHS、出货检测报告）以保证长期可靠性。若应用对漏电或耐压有更高要求，可考虑更高规格的肖特基器件或改用晶体管/同步整流方案。
本概述基于 SS14（DOWO 东沃）基本参数给出实用建议，便于工程师在电源设计与保护电路中快速评估与应用。
Request for quote

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.
